I have an 8kW Sunsynk inverter. I was advised by Sunsynk support that were upgrading the firmware after I contact them via the support chat to query why my battery was not assisting the load when the PV gen was not sufficient even when tge SOC was 97%
Now the firmware is
COMM:E43D - MCU:6027-1724
I have no idea what version was in the inverter before. Is there some way of determining what the previous version was?
