I have a Growatt SPF 3000K LVM-ES, a EG4 -48V100AH battery and 1.92KW solar panels for a years now. I have been using the power to run my freezer, refrigerator, lights and garage opener in my garage.
As the weather was getting hot, I also run 1200 BTU Midea Window AC when the SOC is more than 90% and I turned it off when the Battery SOC went down to 53V or (75%) in the evening.
Then the last two morning, the battery got to alarm mode and was under 49V . I have set my system program to SBU and 51V on Program 12. How come, the utility didn't kick in to charge my battery when the SOC falls below 51 V ? Any suggestions?
