Deye 12kw 3 phase inverter F56 error


Recommended Posts

Hi, I have a Deye 12kw 3 phase inverter with 3 x Dyness Powerbox Pro 10.24 batteries. The dip switches on all batteries is correct in terms of master and slave and all green lights are on.

When I change the settings on the inverter under battery settings to lithium, the inverter gives a F56 error. The comms cable is plugged in correctly in the inverter under BMS and on master battery on IN. If I change to use battery% or batter V it works. Anyone have an idea what the problem can be? I changed the comms cable but still same problem.
