After reading manuals still I am little bit confused about which one to use.
My installation as follows on our sailboat.
A non victron inverter/charger combi
4x160 agm non victron service batteries
280watts solar array charging service batteries via victron mppt smart 100/20
340watts solar array charging same battery bank via victron mppt smart 100/30
A bmv 712 monitor
a venus gx have connection to 100/20, 100/30 and 712 with ve.direct cables.
my problem is two mppts are
ok and works fine in bulk phase,
then they are ok passing to and work in parallel in absorb phase
afterwards they are ok passing to float phase. however in some shady days 100/30 stays in float which is normal, 100/20 turns back to bulk mode which is not normal.
manuals says do not use smart battery sense or smart networking between mppts if there is a gx product in the system. Do I have to use dvcc in order to get two mppts synced. Or can I use smart networking while dvcc is off.
thanks in advance
