Setup (I have attached the spec sheets / manuals for each of the following components in my system)...
1) EcoWorthy 48V 3500W All-In-One Inverter 80A MPPT
2) 48V 200ah LiFePO4 9.6kWh battery
3) Six Heliene 380W solar panels (41.2V max / 9.23amps) set up in 2s3p
Problem...
The MPPT charges the battery extremely slow! It doesn't matter what the SOC is of the battery. When I test the amps coming in from the PV array at the inverter, it shows 25amps (I have some shading), however, the MPPT never shows that many amps; it will show anywhere from 3amps to 12amps (at best). The voltage, however, reads the same as when I test the PV array. What might the problem be?
If I charge via my gasoline generator, it will charge the battery fairly quickly at 20amps; and if I charge via grid power, it charges at the max 40amps and the battery charges within a few hours. But from my PV array, it's just not charging quickly. I have selected the correct battery type in the inverter. Any thoughts or ideas? Thanks!
