That is correct. I have the same 24V GW as yours. P10=2 cannot be changed. I suspect that a 48V model would be factory set to 4 and also not be changeable.

Is the value of P10 on the GW display = 2?

With up to 100ft of 8Ga wire on the solar side of the controller, you can sustain a 10% drop from 42.8 to to 38.52V and still have all the Volts needed to charge a 24V battery. On the battery of the controller, you want to keep the loss lower than 3%. Keep that length as short as practical...

I wrote about this earlier today! link

You meant 20A and 50A, not V. 50A would be 50%, so 41A would be within specs at 41% per battery.

What does the SOK specs say about charge current limits? 82/2=41 would be a 41% charge rate per 100Ah battery.

The Pi is a long DIY story. Fortunately, I have a degree in CS and had a long career in business data processing. I can design and program. Basically it logs data from the AIO and lets me see graphs through a web interface. Don't even think about asking for a copy of it. I run the last test...

Look at my avatar. All DIY. I am running a 5120Wh, 200Ah 24V AIO system with a 3000W Growatt AIO, in the van with 981W solar on the van roof. I have a 30A RV socket in the rear where I plug in my 30A trailer. I set this up so I could travel freely and enjoy A/C overnight. It works...

Not exactly, however here is a graph depicting the last 6 days in KWhs without power saving mode(PSM). There are no AC draws for the last three days. The red line shows 1KWh because I add a 1 to any GW measured KWhs to account for a DC feeezer for drawing directly from the battery. IOW, 1 +...

So then posters that use PMs excessively to discuss topics must have a treasure trove of material they can draw from to copy and paste into public postings, yes? I personally abhor PMs and if I get one, I will ask permission to reply publicly so all can enjoy.

Are PMs searchable?

At Sams Club, the label Duracell usually refers to a battery made by Deka-East/Penn, a company that manufactures in the USA. I had one of those from Bass-Pro labeled XPS. That is a good economy priced battery. Look at the top of the battery to confirm the mfgr. There may be a model no. Mine...

A better question is "What are the manufacturer's charging specs for the battery?". I have used AGMs for 12 years. Stop focusing on various charger's specs and post the battery's specs and then myself or others will be able to advise. Just as a guess, you will be using custom. You might be...

Yes. Your 2S2P array will be 74.4VMP which is inside the 30-115 range.

I don't have an answer for low voltage cutoff. I thought we were discussing what to do if your SCC stops running after a low temp cutoff by the BMS.
