We are having an unusual phenomenon on a customer Victron Quattro 48V 10kW system. In the space of 1 minute there are 4 fault reports followed by 4 fault cancellations, as follows :-
#67 No BMS on Solar Charger [258]
#67 No BMS on Solar Charger [256]
#67 No BMS on Solar Charger [288]
Low Battery on VMS Bus System [0]
BMS lost on VMS Bus System [0]
#67 No BMS cleared on Solar Charger [258]
#67 No BMS cleared on Solar Charger [256]
#67 No BMS cleared on Solar Charger [288]
Low Battery cleared on VMS Bus System [0]
BMS lost cleared on VMS Bus System [0]
The behaviour of the system does not seem to be adversely affected.
The sequence happens regularly every day, seemingly when
- The battery SOC falls to the low threshold
- The battery SOC rises to 100%.
The batteries are 3 x Freedom Won eTower units ?
Has anyone seen this before ? Any suggestions as to what the solution might be ?
