We are normally on shore power
but before we head
south this fall I want to install an inverter
so that I can maintain refrigeration
(X3) without always running the genset. I've determined that all three draw about 1100 watts so a 1500W inverter
will handle everything.
I have two 8D house batteries. If I wire the refrigeration
directly into the inverter then from now on both the friges (2) and seperate freezer
(1) will always be on the inverter.
If thats not desirable then I suppose I could install some kind of selector switch like the one that switches from shore power
to gen power and use it to switch the frig/freeze from inverter to shore. Or is it ok to just leave it hooked to the inverter forever?
I could just use the genset to charge the batts like I do now although they charge from the engines when we're underway (Twin diesel
trawler) or from shore power when we're at the dock
Is there a way to figure how long my batts will handle this inverter draw on a full charge assuming good batts? I imagine it would shorten the batt life some but that's just a guess. How have others dealt with this?
Any input / Ideas
