Have had a Victron Multiplus for years. Installed several others in client boats.
I make it a practice to never use the Inverter mode unless away from the dock
& shorepower, or when the onboard diesel generator
is not running.
At dockside, you can choose the Charger Only
switch position on the Victron, not the ON position with is both charger
Away from the dock
, I typically check to see that no high-current AC loads are connected (like A/C, heaters, water
heater, battery chargers, etc.) before switching the inverter on. Then, I usually leave the inverter on so that 120VAC is available throughout the boat as needed. Works for me.
