Growatt 5kva low voltage inverter fault


Recommended Posts


Someone advised me to connect 3 strings of 4 panels each  in series then parallel. my inverter fault (13) comes on. Is this the incorrect way to wire up.

Fault is there even when i unplug two strings?

what is recommended to wire up the panels on this inverter?

Current set up 12 x 335watt panels

48 volt battery set up.

Thank you for the feedback. Much appreciated. i have changed to 3 panels in series thereafter parallel x 4 strings and the inverter seems to be fine. please refer to the label on the side of the inverter. The supplier advised that this is a low voltage inverter but the amp and input rating is different to the image you shared.
