Hello,
We have 1200aH of Victron Smart Lithium batteries in the house bank of our sailboat. We have 700W of Solar. We would like the system (Cerbo GX, BMS, 2 Victron MPPT Controllers, 2 Multipass Charger/Inverters) to maintain our batteries (while at the dock on shore power) in the following manner.
Maintain batteries at a certain level say 60% (rather than 100% while at the dock plugged in)
Use Solar primarily to maintain the bank and switch to Shore Power only when Solar is not keeping the batteries at a specified level.
Is this possible? What is happening now... is that the batteries (while at dock) are always at 100% and the MPPT controllers scale the power back during the day and go to Shore Power to maintain the float even though there is still plenty of sun... Is there a way to accomplish these two things? It would be nice to have a setting for this that you could flip off to get the bank fully charged a few hours before leaving the dock... but keep this setting for maintaining the bank for the most longevity. While cruising it is not an issue as there is not shore power.
Thanks,
Tony
