- Upgrading our Solar All-In-One Inverter by PowMR. There are so many choices for solar power nowadays. It can get confusing and expensive. This is why we took a measured approach. We built this smaller system to run for a year while we build out our Homestead. By the time we really need off-grid power, we will understand a lot more about the process. We thank PowMR for letting us test this unit. It has allowed us to improve our system capability while providing knowledge to our homesteading community. In the near future, we hope to have a grid-down solar system that will keep us going strong for years.

Thanks for the video! I had no idea that the PowMr Solar Controller Inverter Charger allowed 4,000 watts of solar input at 450 volts. This information has caused me to rethink my solar system. Thanks for sharing! You have added a new subscriber.
Thank you. SunGoldPower updated their system shortly after I put this video out. They seem to be identical now. My SunGoldPower unit was well made. Thank you.
Srne these units. Different companies such as powMr sungoldpower and other companies buy these units and they are labeled or rebadged how do you want to call it with that manufacturer info
Setup would be great. I'm thinking of a Mr power 5000 watt for my motorhome. The setup is similar, so a quick tutorial would be helpful. 👍🙏
I will try to make the video. I am going to upgrade to two 5000 Sungoldpower paralleled. This will give me 10K output at 120v
Great vid
Good video, thank you
Glad you liked it!
this is excellent !!
My understanding of a maintenance menu (317V) is the nominal PV voltage (VoC)that is NOT under load. I.E. VOC of 317V is saying that you are under 450VDC and won't blow it up. However, keep in mind that when winter hits you will see the same panel produce 10-12% higher VOC. Therefore, I would NOT go over 380VDC (VoC) for a summer reading to be safe in all temps.
Thank you for that. I am always learning.
Don't you mean that in Summer, you would see 10-12% higher Voltage Open Current? Solar cells are clearly going to produce more power/ operate more efficiently during summer than winter. Therefore you would be getting higher open voltage current during summer than winter I would think.
Hello, Total wattage output in summer is higher due to sunny hours. However, the context I was writing about is to PROTECT the charge controller. VoC voltages increase when the panel is cooler, not hotter. Therefore, the panel is more efficient in cooler temps. Midnight solar and other sources explain this. My canadian solar panels are rated at 41.2 but in winter I see them crossing 44 to 45v voc. The midnight classic accounts for this so my 150V classic can handle 162v VOC due to that little tidbit. Try it out in summer by pouring ice cold water on your panel and you will see an increase voltage. My point is that a person needs to account for physics because not all controllers can survive above their rated PV voltage input and/or current.

Actually, the panels will produce more voltage in colder temps. Hence, the caution to connect less than the Voc limit to your charge controller. 10% is a common value to use as a Voc limit (total voltage combined) under the maximum. It is a temperature issue, not a solar irradiance issue.
@@Sovereign_Citizen_LEO VOC is Voltage Open CIRCUIT not Current. There is literally no Current with an open circuit. But it is the maximum voltage the Panel can put out. If the voltage is too high it could cause damage to electronic components like capacitors. (I have seen small capacitors explode like a firecracker when over voltage was applied.) Although you could get more solar energy from the sun in the summer, solar cells are basically special silicon semiconductors which change their output with temperature. Warmer makes them put out less voltage, and colder, especially well below freezing temperatures and they put out more voltage. Voltage could be compared to 'electrical pressure'. If you put more pressure into a pneumatic or hydraulic system than it was designed or rated for something can fail. Pretty much the same thing can happen with over voltage which is why this is an important design point to match panels to a charge controller input.
Have you ever had any problems with PowMr going into Overvoltage Charge Fault when the batteries reach full charge? I have a PowMr 10kw with 51.2V lithium and am experiencing this problem. Great videos! And any suggestions would be much appreciated. Thanks!
Tony, sorry to wear you out with questions but here’s another one, lol It seems you upgraded your inverter because the Sungold had limited solar input? I checked on the newer Sungold 3,000 24 volt and the solar input appears to be 4,000 watts now. My question is, if that is the case, would you use the Sungold or PowerMr? I’m leaning toward the Sungold because they have a California phone number where many companies are only email and/or text, thanks. Are most of the similar inverters made by the same manufacturer with different boxes, labels?
Hey Tony, on either your SGP or this PowMR, do you have a Parameter #30, with a value of 1? I have a #30 on my 80A SGP, but there is nothing in the SPG or PowMR manual to reference it. They both go from 29 to 32, so I have no idea what it might be lol.
Thank you for this and privies video , I'd like to ask you, how's your tracking solar systems works so far and what solar panels did you installed?
Please do a vid on setup.
Hi Tony,
Thanks for sharing this great video. I am new to solar and still learning. This inverter has maximum PV in 4000 watts but has output only 3000 watts. What is the point to put more than 3000 watts PV ? Put more than 3000 watts seems to waste because you always get maximum only 3000 watts. Please keep posting more video. Thanks.
You can use 3000 w coming out 24 hours a day but the sun only shines part of the day so the 4000 Watts goes into charging your batteries for evening and night
All extra is put into the batteries so the lights and AC stay on during the dark. It is not one for one either. There is loss during conversion.
@@SOUTHERNSOLARAcademy-nx5mk thanks for explaining. Meaning If my system didn't have batteries, the extra watts put in the inverter is wasted. To maximize the input watt is hook up the battery to use at night. Thanks.
@user713Blvd if you "over panel" your system its a great thing... cloudy days you will have more power to draw from. Winter is the reason to over panel, or rain days.
@@WattsMiner be careful how much you over panel your system buy some certain percentage that they want to name without even knowing what brand of equipment
I have owned several brands of equipment that actually specified much lower percentages.
And on Sunny cool days your solar panels can kick out a heck of a lot more power than you might expect compared to the hot days
GREAT VIDEO, TYvm for info.
I have question on the POWMR box, can you select battery input (ex.) 12v or 24v or 36v etc. Or does the POWMR limited to the battery voltage going in?
Can you only connect a 12v battery to certain one of these POWMR or a 24v battery etc
This is auto selected via the charger based on the volts applied at the battery terminals. It does allow a battery type selection as far as the type of battery.
HOWdy S-S-A, ...
Thanks ...
SUGGESTION: for ALL of your Stranded WIRES = consider crimping on FERRULES before screwing them down in your INVERTER, etc ...
especially on those "BOOGERED" up Ends ...
( ferrules are seriously dirt cheap ) ...

This was a learning system. I ordered a ferrule kit.
Tony, can you provide the vendor, part #, specs for the dc switch you'using for the batteries? Thanks
I don't remember the name. I ordered the ones in the inverter manual. You can download the manual at their website
just curious why you did not add the 2nd inverter to gain 220v instead of just replacing 1 with the other. you could have put the powermr where the sun gold is and ran the PV into just it. then added the sungold and just run battery lines. AC in and AC out to your 2nd leg.
These units are not capable of working together
Srne made these units. The resellers will eventually sell the higher voltage versions. Its a big improvement
They already have made the updated version. Both units have the exact same specs if a person buys one now.
@@SOUTHERNSOLARAcademy-nx5mk I'm considering ordering directly from the manufacturer. I have other of their stuff.
Send Gold 3000 W inverter was updated May 2023 to the same specs
😅 21:05 ibi😊😊
Yes they have.
Why didn't you choose the 5k system @ 48volts?
I explained all of that in the original video. This is just a test system to learn what questions to ask.
what can i say solar is like a drug when you know what you doing there is no turning back
I agree. It is very interesting to me. I have always been a life learner.
What size wire are you using from inverter to batteries
I believe it was 2AWG. My memory is foggy that far back. The original video has the specs.
Can this unit be set to no charging from the grid?
Yes it can. It is very versatile.
Excellent...I am going to get one to replace my existing ..Didn't know they have such powerful inverters and its cheap..
Mine is still rocking and rolling 1 month after installation. It is a solid rig for a good price.
What size wire are you using A.c. output is that a 8#
I don't remember, but it was whatever the Manual called for.
@@SOUTHERNSOLARAcademy-nx5mk Calls for 10# but yours looked like a 8#
@@SOUTHERNSOLARAcademy-nx5mk I have the same inverters I have 2 of them with 2 different battery banks running inter house completely off grid with 3,800w
did you steal this video from the tractor adventure channel?
No. I am Tony and I started a solar channel.
a lot of inverters are made by same people
buy crap , it will crap out !!!
crappy system - buy once cry once with victron
I love your exhaustive argument. Very compelling.
I started with a renogy 400w package to see if it was something that I liked. (Solar)
After a year I moved straight to victron with no issues.
I have yet to cry as I have bought more batteries and other equipment with the money I have saved to date.
Since you repeated that trite phrase how many different systems have you used? Not trying to be a jerk I'm just curious what equipment has failed you?
buy once cry once -- buy cheap u will weep @@williamkn621
The amount that was spent so far (unless sponsored) is worth a Victron. European build seems to have better longevity and quality over Chinese.
