Hello y'all,
I have a battery bank of 4x SOK 12v 206aH batteries, series and parallel, to make a 24v system. The rest of my components are Victron:
24v 3000w Inverter
MPPT 150/85 Charge Controller
Victron Battery Monitor
I had contacted SOK to get the specs to fill in the fields on the Victron App for both the Charge Controller and the Battery Monitor. According to the manufacturer, the Max Charge Voltage for the battery bank should be 29.2v.
We are entering the rainy season where I am in the PNW and I suspect my generator will become my greatest ally in maintaining charge of my battery bank. On 4th day of no sun (second time charging up my battery bank) the generator is going and the monitor reads 27.07v and stayed at that charge voltage for over 1 hour. When I shut the generator off the battery monitor read ~26.6v. I plugged in my laptop (~150w) the voltage dropped immediately and stabilized at 26.47v. The generator ran for a total of 4 hours and charged from 24.03v - 26.47v (generator delivering 1.16kW to the battery bank). This is the second time I have had to use the generator with similar results, the first time after I turned off the generator the Battery Monitor reading 26.8v. Voltage immediately dropping to ~26.6v when low wattage item plugged in. Anyone have any idea on why the system would be hard stuck on charging past 27v? How do I get my bank to reach full capacity at 29.2v?
I am new to off-grid systems, but a former apprentice electrician (AC/grid).
Thank you for your time and reading.
