Have used a IP43 smart charger 12/50 (1+1) and MPPT smart regulator 100/30 several seasons with latest recommended firmwares charging AGM batteries.
Last Monday did i install LFP GBS cells and a BMS, one busbar for load and one for charging, AGM starter battery is directly connected to charge busbar.
Yesterday evening did I stop all charging while I was installing BMV-712.
Afterwards did I connect the new BMV-712 to the virtual network and restarted both solar and shore power charging.
Maybe after an hour did I notice that the starter battery voltage was 16.2 V,
BMS protected LFP cells by disconnecting them.
I expected to see 14.2 or 13.5 volt but this overcharging was a shock.
Created a user profile on IP43 to force a lower voltage.
Recondition has always been disabled.
What can trigger the 16.2 voltage?
Is it me using the Victron features in wrong way:
- no trickle charging of any battery
- IP43 connected to charge busbar
- AGM starter battery connected to charge busbar
- Service LFP bank charging conrrolled by BMS
- via the virtual network does IP43 get voltage figures from LFP service bank from the BMV-712
Is the solution to disconnect BMV-712 from virtual network VE.smart networking
and let Shore power share data with solar regulator via virtual network?
