I never saw a post on this board with as many statements what does not work, or what is not permitted. I clicked on this thread "Youtube claimant to run his house and charge Teslas" thinking it would contain a Youtube link, and there is none.

9k PV, 10kW inverter, 25kWh batteries here. Not enough to be off grid in January and February, but March, yes. I even charge a car on it. Planning to over panel later this year before winter.

Off topic: Just to give you an idea how messed up our PoCo PG&E is. One of my renters called me 2018 that her fridge doesn't work. It was dark. I hoped to just give her a new bulb and feared to be on the hook for a fridge. Upon my visit, it turned out that her house had no power. I called PoCo...

You are free to do this but I think it's an honest bug in their shop software which hopefully can and will get resolved.

Actually: "completely free energy from 9pm to 9am" Why bother with panels? Just charge the battery bank at night from free grid power.

It's been 3h now since I changed [03] to APL ("appliance mode") and there has been no hiccup with the charging. SOC is at 53%. I reduced the current now over night as aim for about 80% by 7am, while I stay in pass-through mode. Next week I will experiment with the breakers that feeds the AC...

Are you saying that only one of the 2 elements work at any given time? (Or none) Makes sense that it's called 4500W then...

Thank you, so I should try PYL. I don't think I tried that one yet. I am thankful for this forum, as emailing SGP would have taken at least 4 to 5 days given the upcoming Christmas break. You guys helped me in minutes! I hope I can pay back one day.

[9] seems high. I lowered mine to 54.8

Wait a moment Solar Assistant can change configuration settings on the SGP inverter charger???? Total game changer!!

1 MWh would get you about 4000 miles. (1 kWh = 4 miles or 25kWh/100m) I think it's 3x as much.

So, 377kWh saved equals $52. 13c/kWh. A $20 electrical bill would be awesome to me. To feel better about this topic, I don't look at $ numbers, just at kWh billed: January 2176 --> 1329 February 1901 --> 1008 March 1903 --> 611 April 1651 --> ??? my math predicts 542 That doesn't...

Easier to change a setting in one inverter than in 5 batteries

I did it in reverse. Bought a PHEV 2 years ago and discovered that the price of electricity is not the same as in 2010 anymore. About 3-4x as much. That prompted me to build my first off grid system, sole purpose to charge the car. In summer, I visit the gas station twice. In winter every 2...

1st battery 100% SOC 54.63V cell voltages 3407mv to 3418mv 3rd battery 97.12% SOC 54.64V cell voltages 3411mv to 3415mv (tighter interval) Whatever it does, the situation has improved since my previous post 90 minutes ago. #3 was at 92% SOC and now it's 97%. #2,#4,#5 are all showing 100%...

Wow that looks almost like my wooden rack! 5 batteries just like mine. Looks great, whoever did that. Wait. No bus bars, just a chain. 😬 And both inverter wires on the same battery 🤕

My solar car charger has a 3000W inverter of which I only use 1400W for level 1 charging, I like to keep a reserve and I built it with two 24V 200Ah batteries. In parallel. They each have a 200A BMS, so I think I could pull in theory 400A with that setup. However, my wire is only good for 195A...

This should be pinned at the top of this thread, if the forum software provides such a thing.

12 noon, and all 5 batteries have SOC 100% 4 of them OVP, 1x "FULL". It's looking really good now. Time to move the electric water heater onto solar.

Hello, this thread is extremely helpful for me as I purchased SGP's 10k split phase inverter and their 48V batteries (4 received, 5th one coming soon). I have mounted the unit and built a rack for the batteries, started to hook up the wires. My question: when connecting batteries to the...

It has 4 mppts, max 13kpv.. but only 10kW output Not worth the $2400 price IMO Unless it can be operated parallel for higher kW I don't see that though Edit: parallel IS supported

Yes, I have this one between battery bank and AIO: Without cooperation between the 2 AIOs, each unit would feed a separate panel with 20 breakers and a limit of 41A (10kW). I rather would have a single panel with a limit of 82A (20kW).

7am, instead of reviewing crypto valuations I ran to the battery shed to record battery status. The 5 batteries have discharged somewhat unevenly, but it's the most uniform ever. Look at column F. It shows the variance and has overall increased since I recorded, with mornings always worst. All...

I think if I wanted to trick my wife, I would copy your blue/purple back lights first. That should distract from the wires that are not in conduit.

I had not paid much attention to the BMS status lately, mostly because of the clouds, the SOC never made it past 90%. However, today we got good sunshine and.. All 5 BMS report "Full" (no runners causing OVP) I have full BMS communications enabled.

I also added an additional battery today. #5 to a stack of 4. And I made a similar observation about uneven amps. TLDR: tech is smarter than me. I had disconnected all batteries and let them rest. Tried to bring all to the same voltage, by charging the new one. I know, Voltage is a poor...

I don't have grid-tie yet, maybe never will. So, strictly charging from pv. Which was on average 1kW, peak was 2.7kW. Which would mean 20A for all five on average (4A each). Peak was ~10A per battery. Tomorrow will be overcast/ rain again.

I believed you until this!

Well, I don't know that much about proper charging. Today SOC is 97% and item 7 is adjusted to 30A. My conclusion is that #7 is not really a setting for me to set but a display.

I have seen 36V charge controllers, and I have seen 36V inverters as well. If you want an AIO, you probably have to go with 48V. My SCC from AmpInt is a real MPPT and automatically senses 12V, 24V, 36V or 48V, provided that your battery is somewhat "full" E.g. it could mistake a really really...
