Good day,
I have a 3x Multiplus 24V working as threephase system with 6x lithium battery 24V in parallel and a Fronius 3kW.
Nowadays the system is showing Error 60 (Battery high ripple voltage) once a day.
The wiring from batteries to inverter is ok.
When the error occurs, the battery voltage drops ~0.5Vcc.
The system have been programmed with and without ESS assistant and PV Inverter Support.
Someone else have this problem? Is there a solution?
