The bad fan in the Multipluses has lead me to replace the stock fans in my MP2 3000s with Noctua NF-F12 iPPC-24V-3000 fans. They are much quieter and ramp up and down just as the original :) best Upgrade ever
I don't understand why most companies don't spend an extra 20€ and put Noctua fans in their products. Did you also check that the temp remains the same?
That's always the caveat with replacing fans, if you're not getting the same or better airflow then the silence could be dangerous. Some designs look for high airflow and others need high static pressure. But if temps are the same it's okay.

Hello Andy. Thank you very much for having an opportunitty of watching your enthusiastic and thus supaa attractive shows. You have become my coach and advisor - I ordered a battery DIY box recommended by you!! Expect some bucks as a donation if/when it arrives from China. I am not able to send you a bottle of wine we make at home for your tasting - so I let you be happy with beers over there in Australia. Wrong calculations on VRM portal occur not only when DC is measured. I experience the same issue with meter ET340 - Victron´s 3F AC meter installed to monitor the grid-tied invertor installed prior my Multiplus II 5000W Invertor. Firstly, at VRM portal it is shown incorrectly after Multiplus (it is uncertain how software understands the sharing of 1F which is basicaly fed by Multiplus permanently). However, in setup menu of Cerbo it is correctly set as connected to the AC1input. It means prior the input logicaly. Secondly, the Grid-tied Invertor´s production is calculated into the overall consumption!!! Therefore, the historical data collection is insane while I do not start to investigate by a help from data of grid provider (from mandatory smart grid energy smartmeter) and e help of application monitoring the grid-tied invertor. I am ready to purchase the second meter ET340 to monitor the consumption if it helps. The question to Andy and to the more-experienced-tehn-me Andy´s followers: would it help? As a positive result to the third Q. Thirdly, in Slovakia the use of GridTied Invertors is motivated by both - electricity supplier accepts overproduction and gives it back with no additional fee (honestly, the service called VirtualBattery is for 3EURO/month) and grid provider allows to send overproduction into the grid system. It is calculated by the mandatory smart gridmeter as the sum of all phases. Therefore, it would be efficient to use all of the production to feed the battery by Multiplus if the battery is not full and GridTied Invertor produces electricity. I am not able to set this kind of feature to be active if it exists. Next, if it is possible to take back part of overproduction to feed the battery by Multiplus it would be efficient to take the energy from battery if the overall 3F consumption (measured by additional ET340) is higher then the overall production by charger and GridTied Invertor. If it possible how to set it to be activated? I tried to look for these questions at victron´s webpages - however, they address the users to check forums and frequent Q&A sections. But I have not found any way how to ask directly victron´s experts 😞 Thank you very for your possible replies. I hope that I will find solutions with your help. Not only Andy´s reply would be appreciated. Jan
Thank you very much, Jan. Very specific questions you're asking and not easy to answer. If the inverter contributes to the consumption, it seems to be wrongly defined in the system. It is set as a load meter and not a PV inverter meter. It all depends on where your inverter is connected to the system. The MP can take care of the AC load including the power coming from the PV inverter if connected on AC-out.
First RUclips video watched after getting back on cellular data after Helene passed through. On the 4th day with no power and no Internet. My tiny 1000Wp panels (4x250W), 24V 200Ah battery, and 2000W inverter has been keeping my fridge and freezer running and providing us some lights, fans, and coffee. Trickle charging the battery from my Chevy Bolt EUV when the sun isn't shining (350W). Thankfully there's 2 free AC chargers in town where I can get more power. Need more solar...
no way man...the Shunt is the most important. With it you get the right voltage and battery capacity...it is actual a very good mesurment point in you installation
The best decision I made for my 48V system was removing the shunt. I’ve had no issues relying solely on the MultiPlus for system management. I still use a shunt on my 12V system for manually adjusting capacity when adding or removing power banks, but it's not really necessary. In my experience, shunt data can be quite unreliable, especially with inverter loads. Even a small amount of ripple can throw off the readings.
How does the MP measure SOC when you have MPPTs? I have never tried that... Edit: I just tried and set the MP as the Battery Monitor in the System setup. It shows no SOC at all any more and the discharge current is without DC loads. So that's not gonna work...
Victron issued a fix for noisy fans in the Multiplus. They will give you a free PWM PCB to connect to the fans if your Multiplus is in the faulty range of serial numbers. Mine sounded like the fan bearings were worn out until I fitted the 'workaround' PCB. It did take two attempts however as the wires were too short on the first PCB they sent me! As for 'DC Power' my Lynx Shunt tells me I am charging my batteries via some DC generation even when there is absolutely nothing connected that could do this. No wonder the SOC wanders out of calibration. For such expensive equipment some of the Victron stuff is rather disappointing even if some of it is also rather impressive. I've also been annoyed by the Victron warranty procedure. A brand new Cerbo didn't work out of the box and I had to wait over two weeks for a replacement and also pay the postage to return the faulty one for testing. That's pretty bad customer service in my mind.
I heard about this before. Luckily mine seems OK and the fans are not too noisy. Honestly, I would not care as the system is in the garage (unless I make videos at this point of time😄)
@16:00 you can adjust the calibration of the clamp meter to get it correct in both directions. Requires connecting to the flash memory IC and changing it, the same way it was modified to default to DC at power on, did it to my unit.
This has also been my setup as well.... I have 15kwh of DIY batteries with no comm, the 1000a smartshunt, multiple mppts, and only a Phoenix 48v 1200va but it has never reported consumption. I figured it is just due to the inverter and hoped it will show up when I move to two multi 5kva.
Same weather conditions here in South Australia too Andy. The big inverter souns like a 747 about to take off when the cloud edge effect kicks in and feeds 60-70 amps into the batteries. Both systems close to 100% SOC at 10.00 am, I'm happy. My 48v Escooter is fully charged, I'm too old and lazy to ride a bicycle.
I'm using the lynx shunt as fuse holder and communication center for my 4 "pieters" only. The SOC I'm receiving van the BMS directly. In my opinion it's the best looking version from available Victron shunts to get my biggest fuse to my system without cables or extra powerrails. 🤑💸 Greetings from good old Germany. PS: I'm using a Adler EF3 fuse with 50.000amps breaking capacity. It fit's perfect in this shunt.
I’m all too familiar with having my hands inside electrical panels and having loud noises go off right when you’re going to make a change. Makes you need to go change your shorts! From what I’ve heard from Victron, there’s no communication between the lynx distributor and the lynx shunt. The only device that will notify you of a blown fuse is the lynx bms. All the lynx shunt does is supply power to the lights on the distributor. The inaccurate voltage on the shunt has always been an issue. I also with that we could see the DC power in the VRM. Doesn’t make any sense why they can’t use the same shunt in the lynx shunt like they do with the smart shunt. The smart shunt has a lot more features than the lynx shunt.
I purchased a fuse blade block splitter of Aliexpress for 21$. It is similar to the lynx but 20× cheaper. Put a Victron smart shunt in front of it, and it tells me everything I need to know and offers great protection at a reasonable price! I will connect my inverter straight to the shunt thought!!
Fully agree. Additionally to that the whole lynx line is NOT 1000A as Victron specs. The busbar inside is 8x30mm which due to busbar calculators is 418-478A depending on which calculator you take. I pulled 550A over the distributor and the case started to deform as it got to hot. All torqued down with corret nm specs due to manual, it was the busbar heating up, load on each 200A fuse was 130A.
@@OffGridGarageAustraliayes I asked several times in the victron forum, also directly to mVader and no answer till today. Your 10mm x 30mm shouldn't get warm with 250A. Either bad contact or bad quality copper. I have 8mm x 40mm busbars salvaged from NH disconnect knifes which are silver coated 99% copper and that gets warm from 450A on. Its rated till 630A to run 24/7/365
That's really strange. The smart shunt simply reports the current running through it and that's what I would assume is the minimal functionality for any shunt. Might this be a problem in the cerbo when data is received via CAN?
There's nothing wrong with the shunt, it is DC connected so can only measure DC current and DC volt and then report that upwards. Upwards is where the error is, ie the display of power based on the report from the shunt. Upwards is probably not asking the shunt for data.
@@OffGridGarageAustralia First upwards is your Cerbo GX communicating with the Lynx shunt over CAN. The problem must either be that the Cervo GX doesn't ask the shunt for data or has told the shunt to disable measurement. The shunt doesn't know anything upwards from the Cervo GX, it can't distinguish between a BMW and a Tesla.
That's what I explained in the video, right? The calculated DC load is not 100% accurate but still pretty accurate. Installing another shunt for the DC load would be a major upgrade to the distribution busbar in the top of the shelf as I would need to separate all DC loads from the main busbar. That's not an option for me.
Only 2 batteries can be connected to the new Power-in instead of 4 with the 'old' one. I'm not a big fan of fuses for battery connections and rather use double pole DC breakers (like the NOARK). They act as battery main isolators as well as safety devices. But they are a lot bigger of course, so it all depends...
For me the shunt works perfect (in combination with 3xMPII). A 0.2V drop in measurement I can confirm es wenn. It is named a shunt - so it does what a shunt is supposed to do right? OK it does do some more and is for what it does maybe expensive. I use it since I connected my batteries via serial and batteryaggregator to the Cerbo. This combination has sometime issues (software bugs or USB instabilities) - getting better but still not perfect. So I use the shunt as BMonitor (SOC...) and BatteryAggregator for DVCC control. This combination works fine. The SOC caclulation of the Shunt fits well (no I have not tested it more than 160days :)). I assume your problem has more todo with the VRM & Cerbo in as with the Shunt. Still it is a bug that Victron should fix. For the shunt they at least should comment on the 0.2V voltage difference.
It would be nice if you could go into more detail about the DC system. I know you've mentioned it a few times. I still don't know where my consumption is coming from, is it the Cerbo GX, DC/DC converter, switch that I've attached? The value changes from 5-80W every second in my 48V system. ???
Where you connect phoenix inverter? In the right or left part of shunt( left is for batteries only and right for consumers and MPPT? Lynx shunt dont report fuses blown , only lynx bms.
All connected correctly. You might be right with the fuses but I'm sure I have seen some kind of fuse setup in the VictronConnect app where it actually showed that...
Yeah it's ridiculous that the leds need a 5v power source from other products like a shunt or bms. It should have its own power supply, but doesn't. That aside the lynx distributor is a great unit. If you think it's expensive try buying 2 x 1000A covered bus bars, fuse holders, lugs, cable and spend the time making cables and mounting everything. They actually work out cheaper than doing all of that and way less time to install. Nice and compliant too.
I have a Quattro system, Lynx Smart shunt, DC power system is enabled although I have minimal loads on the DC side, consumption is measured perfectly adequately and shows in my graph. AC loads are not measured in the shunt, so it's a problem elsewhere related to your system setup when using the lynx shunt. Annoyingly it does lose SOC when updating the firmware, this also meant my scheduled overnight charge did not work, even though it was set to charge to 100%. Lack of being able to set SOC to anything other than 100% is annoying. There are no kWh counters either. For me these are little inconvenienes rather than problems or show stoppers.
Yes it's possible, but the Smartshunt needs to be shimmed out a little for a straight fit if you're using solid copper bus bars to connect it between two Lynx devices. Or, you can flexible cable of a suitable gauge for your loads between the devices.
@@skipr.3419 there is a 10mm version of the Lynx Power In and Lynx Distributor available. Probably made to accommodate fitting of the SmartShunt or BMV Shunt.
I would speak to your Victron designer as I don't think it's intended to use a Phoenix with Lynx distribution. Clearly it can work at a certain level but I don't think they are designed to go together. All the schematics I've seen for Lynx are with a MultiPlus and CAN connection. I think the Cerbo is not expecting the layout you have which is why it doesn't 'detect' consumption, but not 100% sure how you have it all connected.
@@OffGridGarageAustralia the Victon shunt looks like it only relays a "general fault code, that one of the fuses are blown" and only the lynx BMS actually reports which fuse is blow to the Cerbo. Since posting, I've found the Lynx "Peter" uses the I2C protocol to relay the individual fuse statuses to shunt/BMS and then uses VE.Can to report to the Cerbo. I think an ESP32 with its native I2C interface and a CAN transceiver might get the job done. While having the flashing lights working by running power to the "Peter"'s RJ10 is great, I want fuse notifications to the VRM/phone push notifications.
Andy did not 'zero' the clamp meter after setting to DC current measurement. You can clearly see that it records 0.07A while not clamped on any wires - this makes positive readings read larger than actual, and thus also negative readings read lower than actual. Clamp meters are not precision measurement devices, though, so you should not give too much weight on the decimals provided in comparison to shunt-type meters.
@@Stefanfj -- DC Clamp Meters use a Hall Effect device and are effected by the Earth's magnetic field and other man made magnetic fields. They need to be zeroed right before you clamp them over the wire and the meter's axis needs to remain constant.
I know I am late to the party. I had done as suggested and added a smartshunt to measure the DC usage and it is still not attributed to the used power graph or figures.
You are not too late... Victron recommends using a smart shunt but it needs to be configured as Energy Meter in the smart shunt app. Connect to the Shunt via VictronConnect, Settings, MIsc and reconfigure the Shunt as DC Energy Meter. Have you done that?
@OffGridGarageAustralia yep configured as an energy meter and it's readings are being used on the VRM from what I can tell. But still not contributing to consumed
🐸🐸🐸Talking about equipment problems, I've been having issues with error code #66 (incompatible device) apparently you should not use V.E. smart if you use a GX device which is what I had running. Victron community is excellent and the Victron Community Manager immediately responded explaining. I could not see my "Off Grid life" without Victron ❤
@@OffGridGarageAustralia Yes, IO was debating whether to reactivate it too, the two MPPTs used to run identically before and they no longer do so however the Victron experts seem to consider this correct.
@@9111logic I usually have this message only showing when I connected new Victron devices via USB or VE.Direct, or disconnect some and reconnect them on different ports or do a simple restart of the GX. But it does not affect the functionality and everything works perfectly fine. At the end, it is just a warning, not an error.
@@OffGridGarageAustralia Unfortunately, I have both my MPPTs connected via VE. Direct, and I wouldn't be happy to change that. The instructions state that if both are being used the B.T. will be ignored but it obviously isn't the case, at least not in my case. I shall try to reactivate it and monitor the situation purely for academic reasons.
Hi, i have a Lynx Shunt as well, but its only giving me round SoC without a decimal sign. How its possible that in this Video the Shunt is showing 96.2% and 96.1% in VRM at the 20:50 Mark? Do anyone know how i cac get teh decimal signs ?
It should be possible to "fake it" by making a python script that gets the calculated dc valus and then makes a fake smart shunt that is defined as a dc loads shunt. Shouldn't be too hard but i cant do much without knowing what data the lynx shunt provides in dbus-spy
@@OffGridGarageAustralia yeah... i did some modding on venusos, unfortunately i can't make anything for that without knowing what data the lynx shunt provides
The Lynx system is pretty neat, but 1kA is way overrated. I've installed one of the temp sensors directly on the bus bar on one of my installations and with 200A continuous Load it gets to above 60°C within one or two hours. So probably good for up to 1kA short term, but not more than 2-300A sustained load.
That is definitely too hot for 200A. I have never seen such high temperatures at these rates. Could be something wrong with the busbar connection in this area?
@@OffGridGarageAustralia It`s right on one of the shunt legs, I torqued the connection to 13nm as per spec. The bus bar was brand new, and it's in a dry and warm environment. So oxidatzion shouldn't be an issue.
arghhh!!! lol i watch this channel quite often.... clue me in to why several things are named "Peter"... I used to think I knew but maybe not.... the suspense!!! lol
Yup, an ongoing joke about things he doesn't pronounce easily the first time. Tongue tired I guess. I'm sure he can say distributor just fine, he just plays it off as a joke.

You have to enable setting "Has DC system" in VRM/GX and it will measure. Cheers!
I have this always enabled and makes no difference with the Lynx shunt
This is why I have a shunt measuring the DC load, the VenusCalculatedValue is less accurate (and fluctuates like the AC load)
a separate Smart Shunt to only measure the DC load is the recommended method.
That's what I explained in the video, right?
The calculated DC load is not 100% accurate but still pretty accurate. Installing another shunt for the DC load would be a major upgrade to the distribution busbar in the top of the shelf as I would need to separate all DC loads from the main busbar. That's not an option for me.
Andy, you play with the Lynx Class-T Power In yet? Love to hear your opinion before I pull the trigger. Thanks mate!
Only 2 batteries can be connected to the new Power-in instead of 4 with the 'old' one. I'm not a big fan of fuses for battery connections and rather use double pole DC breakers (like the NOARK). They act as battery main isolators as well as safety devices. But they are a lot bigger of course, so it all depends...
Thanks Andy! Big 👍
For me the shunt works perfect (in combination with 3xMPII). A 0.2V drop in measurement I can confirm es wenn. It is named a shunt - so it does what a shunt is supposed to do right? OK it does do some more and is for what it does maybe expensive.
I use it since I connected my batteries via serial and batteryaggregator to the Cerbo. This combination has sometime issues (software bugs or USB instabilities) - getting better but still not perfect. So I use the shunt as BMonitor (SOC...) and BatteryAggregator for DVCC control. This combination works fine. The SOC caclulation of the Shunt fits well (no I have not tested it more than 160days :)). I assume your problem has more todo with the VRM & Cerbo in as with the Shunt. Still it is a bug that Victron should fix. For the shunt they at least should comment on the 0.2V voltage difference.
If you don't have any DC loads or non Victron inverters connected, it will work.
It would be nice if you could go into more detail about the DC system. I know you've mentioned it a few times. I still don't know where my consumption is coming from, is it the Cerbo GX, DC/DC converter, switch that I've attached? The value changes from 5-80W every second in my 48V system. ???
Do you have an inverter connected as well? Turn it off and see what the DC system shows.
Hallo Andy!!!! Wie immer eine tolles Video..👍👍
Danke Dir
Hey man, I like the way you are building a secure room for all your valuable components. Are you going to have a steel door with a good lock on it?
No, just a normal door with a lock. The garage itself is locked so...
I am wondering if it might be possible to replace the shunt inside the Lynx shunt with the 1000 amp smart shunt
Probably not... actually, it might be possible but need some special tools to make a bus bar adapter/extension.
Andy the australian I don't have those device,Just a shunt and the water runs fine
Where you connect phoenix inverter? In the right or left part of shunt( left is for batteries only and right for consumers and MPPT?
Lynx shunt dont report fuses blown , only lynx bms.
All connected correctly.
You might be right with the fuses but I'm sure I have seen some kind of fuse setup in the VictronConnect app where it actually showed that...
Maybe Harold Halewijn (He has a Dutch channel on YT) can get Victron to fix this. He has some influence there like Andy does with JK.
Thanks Andy
Hello Wayne and thank you.
The problem isn't the shunt, it's the software / vrm that needs to be fixed. Not firmware related.
It works with the Smart Shunt though.
Yeah it's ridiculous that the leds need a 5v power source from other products like a shunt or bms. It should have its own power supply, but doesn't. That aside the lynx distributor is a great unit. If you think it's expensive try buying 2 x 1000A covered bus bars, fuse holders, lugs, cable and spend the time making cables and mounting everything. They actually work out cheaper than doing all of that and way less time to install. Nice and compliant too.
I know, I have built such a busbar, installed cables and breakers. It was a hell lot more work than installing the Lynx.
I have a Quattro system, Lynx Smart shunt, DC power system is enabled although I have minimal loads on the DC side, consumption is measured perfectly adequately and shows in my graph. AC loads are not measured in the shunt, so it's a problem elsewhere related to your system setup when using the lynx shunt. Annoyingly it does lose SOC when updating the firmware, this also meant my scheduled overnight charge did not work, even though it was set to charge to 100%. Lack of being able to set SOC to anything other than 100% is annoying. There are no kWh counters either. For me these are little inconvenienes rather than problems or show stoppers.
Is it possible to put a Smartshunt between the Lynx power in and the Lynx Peter? Does it fit, can it be connected?
Needs some tweeking and spacers, but then it works fine.
Oh, and you have to enlarge the holes on the Peter to 10mm.
Yes it's possible, but the Smartshunt needs to be shimmed out a little for a straight fit if you're using solid copper bus bars to connect it between two Lynx devices. Or, you can flexible cable of a suitable gauge for your loads between the devices.
You would have to drill the big bars out to 10mm, because the Smart Shunt has 10mm threads for some unknown reason🙄
That is exactly what I did
@@skipr.3419 there is a 10mm version of the Lynx Power In and Lynx Distributor available. Probably made to accommodate fitting of the SmartShunt or BMV Shunt.
We are waiting for more lifepo4 testing. Also what's the update on JK? They haven't fixed anything.
JK says, it will be fixed by the end of month. That was beginning of October.
More testing coming.
You should call it "Rechts Peter" according to the left one named "Links Peter" 😂
I would speak to your Victron designer as I don't think it's intended to use a Phoenix with Lynx distribution. Clearly it can work at a certain level but I don't think they are designed to go together. All the schematics I've seen for Lynx are with a MultiPlus and CAN connection. I think the Cerbo is not expecting the layout you have which is why it doesn't 'detect' consumption, but not 100% sure how you have it all connected.
It all works well if I replace the Lynx Shunt with a Smart Shunt, consumption is correctly shown.
Does anyone know a way to get an individual fuse blown status from the Lynx "Peter" 😂 to the Cerbo via VE.Can without using the Lynx BMS?
Where is the Lynx Peter connected to if not the BMS or Shunt?
@@OffGridGarageAustralia the Victon shunt looks like it only relays a "general fault code, that one of the fuses are blown" and only the lynx BMS actually reports which fuse is blow to the Cerbo.
Since posting, I've found the Lynx "Peter" uses the I2C protocol to relay the individual fuse statuses to shunt/BMS and then uses VE.Can to report to the Cerbo.
I think an ESP32 with its native I2C interface and a CAN transceiver might get the job done.
While having the flashing lights working by running power to the "Peter"'s RJ10 is great, I want fuse notifications to the VRM/phone push notifications.
Have you contacted Victron about this issue?
Yes
I have the same problem with the phoenix and the venus gx.. no lynx
Andy, don't you think sometimes, that you have too much, and all you need is a hybrid inverter and batteries?
No, I never had this thought.
@@OffGridGarageAustralia i c
Victron the best!!!
My question would be, does the smart shunt / bms connected to the venos os show a consumption bar in the vrm even if no AC load i connected?
Yes, it does. Tested and confirmed.
Thanks for this 1.
Why does the clamp meter read lower current on the negative cable?
Andy did not 'zero' the clamp meter after setting to DC current measurement. You can clearly see that it records 0.07A while not clamped on any wires - this makes positive readings read larger than actual, and thus also negative readings read lower than actual. Clamp meters are not precision measurement devices, though, so you should not give too much weight on the decimals provided in comparison to shunt-type meters.
@@StefanfjI see. Thanks for the prompt response.
@@Stefanfj -- DC Clamp Meters use a Hall Effect device and are effected by the Earth's magnetic field and other man made magnetic fields. They need to be zeroed right before you clamp them over the wire and the meter's axis needs to remain constant.
@@rpsmiththank you. The best comment on this issue imho now I understand what I occasionally did wrong with it and the "why". Thx! 🎉
@@camielkotte -- Correction! Smart Shunts don't use Hall Effect, DC Clamp meters do! I don't know what I was thinking when I wrote that. :o)
I know I am late to the party. I had done as suggested and added a smartshunt to measure the DC usage and it is still not attributed to the used power graph or figures.
You are not too late... Victron recommends using a smart shunt but it needs to be configured as Energy Meter in the smart shunt app. Connect to the Shunt via VictronConnect, Settings, MIsc and reconfigure the Shunt as DC Energy Meter. Have you done that?
@OffGridGarageAustralia yep configured as an energy meter and it's readings are being used on the VRM from what I can tell. But still not contributing to consumed
@@cmcb7931 Thanks for confirming. Very strange indeed.
🐸🐸🐸Talking about equipment problems, I've been having issues with error code #66 (incompatible device) apparently you should not use V.E. smart if you use a GX device which is what I had running. Victron community is excellent and the Victron Community Manager immediately responded explaining. I could not see my "Off Grid life" without Victron ❤
I have this error from time to time but ignored it. Smart Network is the best feature...
@@OffGridGarageAustralia Yes, IO was debating whether to reactivate it too, the two MPPTs used to run identically before and they no longer do so however the Victron experts seem to consider this correct.
@@9111logic I usually have this message only showing when I connected new Victron devices via USB or VE.Direct, or disconnect some and reconnect them on different ports or do a simple restart of the GX. But it does not affect the functionality and everything works perfectly fine. At the end, it is just a warning, not an error.
@@OffGridGarageAustralia Unfortunately, I have both my MPPTs connected via VE. Direct, and I wouldn't be happy to change that. The instructions state that if both are being used the B.T. will be ignored but it obviously isn't the case, at least not in my case. I shall try to reactivate it and monitor the situation purely for academic reasons.
@@9111logic I have both connected since the beginning of my journey and I never had any problems.
Have you seen the new Lynx Class-T Power In?
Yes
Hi, i have a Lynx Shunt as well, but its only giving me round SoC without a decimal sign.
How its possible that in this Video the Shunt is showing 96.2% and 96.1% in VRM at the 20:50 Mark?
Do anyone know how i cac get teh decimal signs ?
Ok, Updating the Cerbo GX to 3.42 solved this
Thanks for sharing.
Thanks ✌️
Dieses Jahr noch die volle 100K ?
Yes, maybe...
Any news on the JK 15.33??
'it will be finished by end of October' was their answer
So you are selling it as a Demo fuse holder? lol As always a good video..
Yep, it's already sold.

It should be possible to "fake it" by making a python script that gets the calculated dc valus and then makes a fake smart shunt that is defined as a dc loads shunt. Shouldn't be too hard but i cant do much without knowing what data the lynx shunt provides in dbus-spy
Sounds so easy when you explain it.😄
@@OffGridGarageAustralia yeah... i did some modding on venusos, unfortunately i can't make anything for that without knowing what data the lynx shunt provides
The Lynx system is pretty neat, but 1kA is way overrated. I've installed one of the temp sensors directly on the bus bar on one of my installations and with 200A continuous Load it gets to above 60°C within one or two hours. So probably good for up to 1kA short term, but not more than 2-300A sustained load.
That is definitely too hot for 200A. I have never seen such high temperatures at these rates. Could be something wrong with the busbar connection in this area?
@@OffGridGarageAustralia It`s right on one of the shunt legs, I torqued the connection to 13nm as per spec. The bus bar was brand new, and it's in a dry and warm environment. So oxidatzion shouldn't be an issue.
@@djordjeblaga7815 Do you have a thermal camera to inspect the area around the hotspot? It will tell you what is going on.
@@OffGridGarageAustralia Yes I do, I'm going to do that the next time I'm there.

arghhh!!! lol i watch this channel quite often.... clue me in to why several things are named "Peter"... I used to think I knew but maybe not.... the suspense!!! lol
I think it originated with a Chinese inverter with a name that Andy found difficult to pronounce. So he decided to just call it “Peter”
Yup, an ongoing joke about things he doesn't pronounce easily the first time. Tongue tired I guess. I'm sure he can say distributor just fine, he just plays it off as a joke.
I can say it once or twice but when it comes in every second sentence, it just won't work any more.😄

refuse to use their lynx junk, its just another horrendously over priced fan-boy item they can rip you off with.. its about 2000% over priced.
I actually quite like watching your videos. But I think it's absolutely impolite to bite the viewer in the camera and not cut it out. For a live stream - ok. But this isn't a live stream and let me tell you, you're probably the only one who thinks it's great.
