Hi there, I have a growatt SPF 5000ES, with 8 AGM Batteries and 3 x 450 Watt JA panels, now on the Inverter it says MPPT voltage range 120 - 430 VDC and reading off the front panel display of the inverter it says it has 137 VDC from the PV , yet it is neither supplying power to the load or charging the batteries.. I ran through the standard settings and maybe I missed something ??? Anyone have any ideas or do I simply need some more Panels to boost the voltage. Many thanks in Advance
