Here is my test setup
8 x 520W Bi-facial Jingko panel tilt 60 degree (on only one string MPPT #3)
30 KWh LIFEPO4 battery set up as a lead acid on LUX inverter
Output at 12am near mid day
PV = 3761W
Grid = 3542W
Inverter = 37W
Bat charging =112W
DC / AC conversion efficeincy = 3542 / (3761-37-112) = 98.06% (my rough calculation)
NOTICE: the error on the battery voltage reading of 53.5V (lower than actual by 0.6V).
This will cause overcharging of the batteries connected to this inverter.
