Hello everyone,
here is my system:
2 MultiGrid 48-3000-70 (MASTER & SLAVE)
8x6 Battery Crown 350ah
PV inverter at AC out 2200w solar pannel /PHotowat(DANFOSS) ULX1800i
. So I use ESS ,it ran perfectly for about a month, which means I could charge and discharge the battery with energy from/to grid ,setting grid point to use the battery at night with A/C
. Until one day,nothing is working,and my Multiplus stills in Absorption and Float
Sometime the ESS reacts to the setpoint ....My SOC stills at 97% to 100% and most time, these LEDs Mains On, Absorption and Inverter are on at the same time and now the Inverter led stop lightening...
I've done:
-all firmware to the latest
-resseting
thanks for your help
