EG4 Pro Wall Mount Batteries (What is optimal setting in Sol-Ark 15K Inverter?

[Bluetrader2222]

I have 3 EG4 Batteries and Sol Ark 15K inverter setup in closed loop. I had it in Voltage but noticed the batter is better controlled via closed loop. What I wanted to understand is what is the SOC 10% voltage? So far I get 51V for 1% SOC. But yet the spec says 46V to 56.2 is 80% range. I did notice when I was in voltage mode the batteries tend to DROP voltage Fast 50 to 45v. So the fast drop in an indicator of 0% SOC? This was taken this morning on 1 of the batteries and they have cycled empty to full for at least 20 days.

I wouldn't regularly cycle them to much below 20% SOC, if you want to get the most longevity bang for your buck.

What is your Sol-Ark Battery Empty setting? My understanding, it tells the Sol-Ark what voltage is 0% SOC. I set mine to 45.5V. Not EG4 batteries, so your number may be different.

It was 48V and I just changed it to 45V because EG4 told me empty is 44.8 triggers shutdown in BMS
