Enjoyable watch. I totally relate to you worrying about the relay blowing it all up, worse case scenario, even though it can't. I would set a timer a minute before and watch it kick in myself. But yeah.I bet when you got into bed. you were thinking about it all and how you could improve the next day. Your enthusiasm is encapsulating.
Hi Andy,I love watching your clips here on RUclips ,one problem is that I'm loosing you, you giving us so much info it go's straight over my head, I lost you completely not every one is so knowledgeable in electronics And I tough this info is done for people like me Regards Jack Australia
You probably figured this out after 4 years, but for other people coming across this, you dont need a relay you need bus bars or victron distributor to share the power.
Great in depth video. Swap out that relay for a DPDT solenoid. A good one will handle 65amps continuous no worries. Thats what I did. Cheers from the sunny outback of South Australia !
You can hack the wind turbine diversion controllers to do this with solar. I've done it, works only with voltage, though, not S.O.C.. But at least you don't need smartphone, bluetooth, etc to do this. Really good for us old school types !
I know this is an older video but how did the system work out over an extended period of time as far as triggering the relay to turn on the Greta inverter? I’m looking to do the same exact thing since my five large solar batteries are kicking out being charged up here in the daytime and I have an excess amount of power that is just being bled off/wasted. Great video and appreciate the information. In case I missed it, what kind of relay is that and where can that be purchased? Thank you
As for the monitor for your batteries, I assume you have the batteries wired either in series or parallel depending on what voltage system you’re running and you’ve got the monitor showing the overall combined power of the batteries as opposed to the power level of each individual battery correct?
OK, I got a relay to do the same as you. But, when it switches off, it sends a voltage spike back down to the voltage sensor as its an inductive load, knocking the sensor out until I power it off and on again. How did you get around this? A diode? Which one?
The problem I have is not much energy is being used during the day, whilst I’m at work, so I thinking more batteries, perhaps double the storage and have a relay do the same thing, switching between banks, trouble is 60 amps is a lot for a relay to handle. I did look into it 6/8 months ago, but could only fine one type able to handle this level amps, needless to say it was expensive so I chickened out. But this video has stimulated my interest again. Any ideas people.
Good setup. I was thinking that the Raspberry pie was the clever bit of tech but actually the victron battery meter is the clever part. Now you just need to put the other batteries (in your grey box) onto the solar inverter to provide power whilst your main batteries are charging. lol That would make a crazy setup
Hi very entertaining and informative but I am a bit of a novice and have solar panels already into grid now want to add a small wind unit . Can it just be plugged into the mains or what please is simplest way please. Regards Terry
Watching the series on solar shed. Doing my own 400W system with 120Ah battery for 12v shed/garden lights etc. Love the Raspberry pie monitor via internet. I'd love to know more about setting that up. Any suggestions on others that might go in depth on this?
How far down does the Grid Tie pull the panel voltage when operating ? Do you even need the relay ? When the battery is charged it will stop pulling power from the panels. Grid tie would just pick up the current available? If both the Grid Tie and the charger are of the MPPT type I don't see why it wouldn't work.
Hi Andy, I know this video is old, but that relay is rated for 10 amp AC, DC could possibly cause an ARC and melt the terminals or weld them together, maybe better off using it to connect the AC side of the grid tie
Fantastic series this and I'm already thinking of getting a panel for the shed. So with the tie grid inverter pushing power back to the house does that mean it's just consumed within the house? We have one of the new electric meters and it shows energy imported and exported.
Thanks. Yeah energy from the grid tie goes into the house. As it’s only 300-400W it just gets swallowed up by the house loads but it does make a bit of difference. My house base loads are never lower than 400-500W so my grid tie inverter never “exports” any energy to the public grid...and basically the meter doesn’t know any different it just sees a slightly reduced consumption.
andy kirby Just been running tests on my grid tie and notice my eon energy monitor that has a clamp on the positive meter cable actually goes up when grid tie is feeding in power. I guess it's reading flow in both directions. I did think it was maybe to do with importing more than my baseload but it's not. I checked the Landis and Gyr smart meter(ex British Gas and now a dumb meter for my new supplier). On that smart meter I can see the real energy supply to my house down to 20W. I'd love to connect my old British Gas monitor back to the smart meter as that function should still work, but I need a pin to bind the energy monitor to it and no longer have it. Scratching my head a little as would like to monitor what's going on more accurately. Wonder if the Owl is more accurate?
Update. Been spending way too much time looking at an alternative energy monitor. For budget concious people it might be worth looking at the Ecoeye PV Energy Monitor, it comes with two sensors and works out generation and consumption . One sensor goes on the positive AC fro the grid tie and the other sensor goes inbetween the meter and CU. Also seems to have a funky trafic light system depending on if your exporting or consuming everything. I need to get a life as the energy monitor obsession is like a disease ☺
Energy monitor update. Clamped Owl monitor to inverter positive output to monitor watts coming out. I bought a GEO Minim LED monitor that clamps to meters flashing red light area. This now matches what the meter reports. The clamp meters will add solar and consumption so you don't get an accurate figure. I've done a quick vid on my channel which I will upload shortly. My energy monitoring saga is over........ Flymo 1200r robot lawnmower arrives tomorrow😀
Some meters will flag the export if you wont register yourself with feed-in tariff. Other thing is feed in when the grid is down. You need to make sure that inverter will switch off when grid is down. Otherwise that is against the Code.
i had the very same setup. alright to experiment, but the contacts got burned out after a while. also use a diode across the relay winding contacts to extinguish the high voltage created when the relay gets deactivated.
You might be interested to know your Victron controller has a Relay output to do this exact function without the BMV - it can be set in the software, its on the VE port (turns one pin on when batts full) Very nice setup you have there!
Hi Yes, thanks for that but I think you can’t use the VE direct for comms and relay at the same time... I’m not sure if it’s in this video but I’m using a raspberry pi running victrons venus software and have all the parts connected to the pi via ve direct.Thanks for the comment 😁
yeh unfortunately so as it uses the same port, just thought it might be useful for ppl who dont have the bat monitor and want to use the excess power , im using it to switch the pv to a second controller on another bat bank
Could you just split the feed from the solar panels to the charge controller and the grid tie? If the batteries are full, the charge controller wont be pulling many watts, so the extra will just go to the grid tie??
Its growing fast mate it looks like a great system. I do take a keen interest in this sort of thing so that i can pinch ideas from all me friends that have built similar systems but iv got to say yours is mint. Every one else is very conservative on what they spend but u just go for it and try all sorts of options. Nicely done mate
Hi mate, I remember!😁 yeah look for the best deal on panels, midsummer energy are a good supplier. Microinverters are ok but I prefer one big grid tie, it can get expensive very quickly, battery systems cost a fortune and the payback is a long time!
@@andykirby Thanks mate much appreciated. Will check out this site. Electric prices is a joke. Need all the solar I can get. Lol. Still Love watching your vids. Keep em coming. 😉
I have a compressor fridge. is there any way to wire it up to the load ports of a charge controller, so that it runs off the superflous solar during the day, but switches to battery power when the sun doesn't give enough power?
Watch it with inductive loads , (coils) the amp rating on relais are usually for resistive loads (lightbulbs) with inductive loads the amp rating usually goes down with 40 procent
Hey Andy, do the RJ45 ports not work on the energy meter? Would save you a usb port on the pie and if they work you should be able to hook it up to the shed network through your router? The other thing you might want to check is if the relay is switching under load you might get an arc over on the contacts that could potentially cause pitting on the contact points that could lead to problems with the transfer of power, you can put 4 ceramic disc capacitors (0.1mfd 100V should do), across the contacts 1 on each contact to reduce the arc over when disconnecting, the different sides mppts. Keep the vids rolling love them. Best wishes, Charles.
Oh bummer, that would have been a plus if they were ethernet, Oh well. The caps are something I learnt doing PLC load switching..... the one thing I missed out was the relay, yes, you can look at getting a bigger relay if needed, but what you would want for higher current loads would be a contactor, it is physicly allot bigger, but draws more current, this is becuase it has a much bigger spring to pull up on, this 'causes the "switch" action to happen allot quiker instead of a click you get a "CLACK" sound, and a contactor is made for higher load switching, the other thing I would warn you about is mixing diffirent wattage and voltage panels together, the higher wattage panels will start feeding back into the lower wattage panels causing them to heat up OR melt which is not wanted and could turn out disasteras for the person who does it if you put diffirent panels up give them them their own mppt, I don't mean 50 or so watts but if you look at 100 watts or more give them their own mppt...... Regards.
No point in having Float Charge on LiFe cells. Here I just use Ford Automotive Relays dime a dozen. They're good for 30A. Need more , use more parallel .
This is a bit of an adventure video. You shouldn't use ac on DC. Basics you've used a NO NC relay, so your normally open goes to the battery and the normally closed goes to the micro inverter. I would have gone for a SSR higher power relay (60a/70vdc) this uses less power. I would have also gone for a normal meter, there the same but show the kWh as digital or analogue. Doesn't help when you buy in to Victron. The MI uses nrf2001, someone's made a video and posted the protocol for it. (Git hub) I like the idea of what you have done. I'm playing catch up on solar as I'm 2007 era. I dropped it due to battery costs and performance was terrible. Comes in handy being the engineer, as I bought stuff, it broke and now making my own...saves a tonne of money, takes a lot of time though.
You lost me with the ebike - 12 months spent and now I've sussed it. You've lost me with this one - another 12 months of reading, head scratching and swearing to do :-)
Can i ask how you are switching the Grid Tie on & off , iv just had mine turn up , Got the relay etc , But the manual states (Never disconnect PV while inverter is active as it will be damaged.) just wondering how you got round this?
Haha! I didn’t read that manual actually, but it seemed to work ok, I’m only running 2 panels and around 350W peak so maybe at that level it can handle it ok. I’m not currently using this method as I found the relay was getting quite hot and would probably eventually fail, if I try it again I’d use a contactor rather than a smallish relay. At the moment I’m switching the PV voltage manually with circuit breakers and it’s working fine. Hope this helps!
Im working on a similar setup.. basically want one of these grid ties to cut in when the batteries are fully charged or at the least to be able to turn the grid tie inverter on/off remotely Thought it was going to be a a doddle using the VE bus output and the relay , But the Grid tie inverter manual says (*Magic smoke*) Think it maybe possible to leave the grid tie inveter connected directly to the batteries and switch the Grid on/off vier a relay instead - either that or i may go down the road of a Change over switch , i duno so many options this hobby seems to be never ending!
Lithium batteries pull hardly any current at all once they reach the voltage your providing. It just peters out. Nothing like a Lead Acid cell. Float Charging is sorta worthless. They will Absorb a bit more if you keep the float at your Charge voltage.
Can someone please tell me if the grid tie inverters work with smart meters? I'm not looking to make money from this venture but reduce my outgoings. I can get 1200w on my extension roof so wanted to utilise the space and save the planet
That relay doesn't look like a high current DC relay? A AC relay will have a max of 10amps AC but dc rating that might be around 3 amps. I would change the relay to a DC one :) Look at the thin wires inside the relay vs the much bigger cables you have going into it which will cause a big loss
Yeah to be honest it looked a lot bigger when I ordered it. It’s getting hot though now the sun is out so I’m gonna need to change it if I keep it setup this way. Thanks for the comment.
It's only a 10A AC relay, and you're feeding the DC to the GTI? That would be closer to 20A, so looks like you'll have to replace that one with something else!
Total watts used in 24 hours = watts in thousands l20w is . 120 thousand watts Or . 12 kilowatts If your average watts used was 120, then .12 kw x 24 hours 24 x . 12 is 63.2 kw hours 63.2 kwhours can cost us . 15¢ each totalling $9.48 That was almost $10 sold back to the elec co. I. 1 day
I did a bit of reading and consulted my electrician, basically anyone can wire up a system like this to the mains if they are competent enough, you are not allowed to connect a grid tie inverter via a 3 pin plug... but we knew that! Inverters must be certified for anti islanding in the country they are used in. Other than that just get the sparky in.
Enjoyable watch. I totally relate to you worrying about the relay blowing it all up, worse case scenario, even though it can't. I would set a timer a minute before and watch it kick in myself. But yeah.I bet when you got into bed. you were thinking about it all and how you could improve the next day. Your enthusiasm is encapsulating.
Excellent. You got the solar bug now and no cure.

hi can you do another video on the wiring of the relay and how its switched over i have the same setup as you just looking at grid tie's thanks
Good on you Andy
Good show mate
Watched it last night and watched it again today.
Couldn’t find the link for the relay.

You should not use AC Relay to Switch DC current you will melt the Relay contacts if DC arcs...
Use DC Relay
Ex automotive relay.

Have fun. be careful, the GTI capacitors will cause arcing during switching. Over time, mine caused the switch to fail.
cables everywhere, I love it, my sheed looks the same:)
Hi.... Can i have your schematic on how you wire the relay with that of your GTI and Victron Charge Controller?

hi where gridtie cable connect to the replay and where white cable come from and connect to the relay
Lithium batteries pull hardly any current at all once they reach the voltage your providing. It just peters out. Nothing like a Lead Acid cell. Float Charging is sorta worthless. They will Absorb a bit more if you keep the float at your Charge voltage.

Hi! Found your video randomly. What's up? You like batteries?
What relay did you use? Can we have a link to it?
It doesn't look like it will last long. Don't think it is rated over 30V DC.
hi andy any update on how this setup is going
Hi yeah it’s going great, I’ve moved it into a rack now and it just sits and does it’s thing, there will be a proper update soon.😉
andy kirby good I'll be waiting on for the update I'm wanting to do the same thanks
Nice shed 👍

Yeah to be honest it looked a lot bigger when I ordered it. It’s getting hot though now the sun is out so I’m gonna need to change it if I keep it setup this way. Thanks for the comment.
Can you change it for a solid state relay?..also I would start labeling all you trips/breakers as your changing your system so often..
It's only a 10A AC relay, and you're feeding the DC to the GTI? That would be closer to 20A, so looks like you'll have to replace that one with something else!

A diagram would be so much better Thant pointing to a rats nest of wires. Very hart to understand. Not very helpful but an awesome idea.
I think you can see some good advices on Avasva solutions.
hi any 1 can explain or show me how to wire relay to solar charge and gridtie and white cable i will pay some $$ thanks
did you ever figure out how to set this up?
just wondering how legal is that DIY
I did a bit of reading and consulted my electrician, basically anyone can wire up a system like this to the mains if they are competent enough, you are not allowed to connect a grid tie inverter via a 3 pin plug... but we knew that! Inverters must be certified for anti islanding in the country they are used in. Other than that just get the sparky in.
When the grid companies swindle millions of pounds through faulty meters each year it's legal to opt out of paying.
Beyond me.. 😂 😂 😂.. Thick as shit me...
