Q & A

Inverter on or off ?.

Should I switch off my boats inverter/charger whilst out cruising ?, because there's nothing being used for mains type power at that time.

WW says:

Most inverters use very little power when cruising, however, they do use some power- often drawing less than one amp for high quality switchmode inverters, through up to 5 amps for transformer based units. So, while you might save some energy when cruising, it probably wont be noticeable in the larger scheme of things.
However, if you are not using the inverter overnight while out cruising, or if you leave the boat for a day or two, then it would be worth turning it off. Having it on while cruising is probably not going to make any noticeable difference to the battery charging rates, but an older combi might draw say 2amps current in stnadby- so overnight could take 24Ah plus from the battery bank- which is significant.
