I have 2x Sunsynk inverters with 4x fredom won 5kwh batteries as well as 20x 460 panels on the roof. So,almost totally of grid.
Battery discharge limit is set to 24%.
Here is the problem.
Load indicated at night(while on battery) on average 1300 watt. (As per Sunsynk app).
When battery SOC reaches 24% it switches to grid power as per design. All good. But. Now the load suddenly changes to average 900 watt. No change in load conditions. I’m still catching zzzzz’s.
This change in load is the difference between batteries pulling through night or not.
Any opinions?
