It has only been 3 or 4 hours.. I just walked out there. Nothing like standing in the rain peeking at expensive equipment that's rated "indoor only".
But you're right. The SOC numbers are within 1% and the current is about the same from all 5, no weird stuff like 1A here and 5A there.
Of course, having all of them "full", whatever that means, helps a lot.
I am so glad that @marionw looked a bit longer at my battery photo.

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 recorded data was in user mode until the 2nd last row where I went back to full comms.
The other big improvement is that the inverter now shows the AVERAGE of the 5 SOC values. Not just the master battery's SOC.
Now I just need to see if I will get OVP issues with *proper* closed communications.

Good! My batteries definitely evened out and are looking better since a few full charges.
That SOC value is due to the comms re-enabling.

That looks good, don’t be too hard on yourself about OVP. In my opinion it’s somewhat natural in a battery groups early lifecycle, with these L16 default settings we are charging and topping off alittle more aggressively than relying on a lower voltage float and longer timelines to “fill” each cellular module, the OVP is just a byproduct of your modules not living together for a while, once they’ve lived and charged and discharged together you’ll see more consistency in delta soc and you won’t have mods reaching the finish line before other mods are often (OVP). In my opinion it’s not hurting anything, these cells will reach end of life with time before death due to exhausted performance imo

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.

Your chart is probably better for the batteries, staying between 20 and 80.

Yea but it's terrible for my grid usage..
CaliSunHarvester
Solar Enthusiast
Oh
I guess without grid you would go below 20.
I don't use enough (solar) electricity. Clearly, having panels at 100% by noon is not good.
January utility consumption on the property will be 1200kWh. The SGP delivered about 150kWh. The other 2 pv installations delivered 200kWh and 160kWh, so total consumption is 1710kWh of which 510kWh came from solar (30%).
I have a lot of space for savings.
Electricity cost in December was 44c "usage" + 16c "generation" = 60c per kWh.
There are taxes and fees on top of that.
And prices increased 13% since then.

For December and January I'm at about 50% total electric provided by solar/battery.... I'm wondering if Xcel (the power company) will notice...

Around here, everyone gets letters that they use too much energy compared to peer accounts. Every account gets the letter except the vacant vacation homes.
The letters are supposed to make us feel guilty and swallow those new higher bills.

Yeah, I get those too but actually mine is in the bottom of the range already (before my Solar Power System).

No, because I've only got 6 circuits connected (they are the critical stuff, but ... ) If I go fully legit at some point I'll probably set it up to handle up to 100% of the house/property.

No sun today...

@CaliSunHarvester Same here, I am full by 12:30pm usually and I have everything on my inverter now except the stove, well pump, and water heater. I need more batteries to store it because I’m only making it to about 2am on my batts then clicking over.
I think the fact that I live in Florida and you’re in Cali is why. I think we’re getting more sun.
I’ve noticed that during the day my panels are absolutely PUMPING out juice, I can’t use it all. I’m happy with my inverter it’s been kicking a$$

You have 2 batteries, right?
I have 5. Rarely go below 50%. We have a bad weather streak these days. PV made 1.67kWh today.
And I have not figured out how to feed AC into the inverter. 15A single phase did not work.
I thought I would get a 30A outlet from the old dryer, bit it turns out that the new heat pump dryer uses the existing 30A outlet.
Also, I am not sure that 30A 240V is enough to feed the inverter.
What kind of breaker did you hook the inverter up to?
My main panel is discontinued, so I cannot buy a new breaker for it, but maybe one of the sub panels could feed it.
Right now I try to minimize solar battery drain by using these e.g. for USB charging.. I know, it's silly:

I've got my AC connected via a 40A breaker which formerly went to a 220 air conditioner.

P.s.:
About half the population in Santa Cruz County has no power right now it seems. When I told the family that the entire upstairs will continue to work, they were happy. I didn't mention the fine print of required sunshine by Tuesday.
They gray areas that have no outages are uninhabited mountains.

Congratulations! Power outages here are rare...only a few in twenty years, but I'm kinda looking forward to the next one.

It's times like those that make every penny spent worth it.
As far as grid charging, you need 240V.

We have several accidental outages every winter, and sometimes intentional outages in summer.
They call it PSPS = public safety power shutdown. E.g. if strong winds are forecast combined with high summer temperatures, then the utility company shuts down power until conditions improve.
It's ridiculous.
how about people that want to charge from a generator? Many generators put out only 6kW to 7kW, which is 30A. So, 30A should work, with the right settings, I guess.
