Thanks for the replies folks. Cruising/off-grid is easy. I would have 3 independent systems, 12v and the two different AC ones. No switching between them, either AC can charge the batteries
via different chargers.
For my own peace of mind, and for safety
I will need to label the wiring. Seeing a black wire and wondering whether it is 12v neg or 110v hot isn't good - it needs to be obvious. There will be a lot of work
just doing that - the boat
is 30 years old, has had a large variety of people work on it adding stuff. And occasionally some have not followed the wiring colour code standards.
Its when connected to shore power
while in Marina's that it could be problematic, from regulatory and/or insurance
angles. And possibly for selling, although that isn't on the agenda any time soon.
This thing has two gennies and a total of 20 batteries including the two in the dinghy
. Lots of flexibility to configure the way I would like. I have in mind using the existing 2000W inverter/charger coupled to the 2.5kW genny, and putting in a new and larger 240 v inverter/charger coupled to the 7.5 kW genny and shore power
. I will change the washer to a front-loader, mainly as they use a lot less water
and my holding tank
is just way too small at present. The dryer works well so less inclined to change it out. Other stuff I would prefer not to replace until it dies, hence some effort to have a compliant dual AC voltage set-up.
