Could I please ask the community's advice regarding the following:
I use solar panels to charge 2 x 12 V / 200 Ah batteries in parallel that supply a 1000 W inverter. A BMV-712 Smart device with shunt controls the inverter (on/off) via a relay. A small UPS and switching station ensures the switchover to mains is eventless (computer and monitor). On really miserable days I use a CTEK charger to charge the (lead acid) batteries manually.
From my research, I believe the Victron MultiPlus 12/1600/70 would be a viable upgrade. If I've understood correctly, configuration of the conditional AC input connection will mean I can make the batteries the primary input. The built-in UPS function will bridge the switchover both ways and when on AC, the unit will intelligently charge the batteries.
The other alternative would be the Victron MultiPlus-II 12/3000/120-32 which from my research offers better grid compliance and more performance all round.
Would really appreciate any feedback.
Best regards
