Hello all
i have installed 12 panels 285w connect to a growatt sph3000 and 200ah batteries.
the issues I have is :
- the inverter discharge the batteries below 50v even that I configured the LV at 50
-at night wen the batteries discharge to 50% the inverter start to charge with 210w then discharge a little more. And do this all night long until the PV have enough power to charge the batteries.
-wen I set export limit to 0, sometimes the system export to grid draining also from batteries. I thing the batteries must be use only for load house, not to export.
any one can help me to try do solve this.
best regard and thanks
