"why do you have 2 start batterys? ditch the 2nd one, and put the house battery on number 2 of that swtich. the house is the backup starting battery, and now you can jumper between house and start if ever needed for charging or starting."
If I were just bee-bopping around the coast all the time I would not bother with another starting battery. But, I spend a significant amount of time every year in the 50-100 mile offshore
range, in remote
areas, and in third world countries where there is not a west marine
in every costal town...why wouldn't I want an "Option C" to start my engine(especially when I have plenty of room for another battery).
"you need a battery switch between the house battery and house panel, and should have a main fuse as well."
already in place I just didnt include it on my diagram
"you need a battery swtich between the house battery and charger / inverter, and also a class t fuse."
I am planning on having the fuse spliced into the battery cables
when I have them made. I wasnt planning on adding another battery switch but I think it is a good idea. Thank you.
"the ac wiring is totally wrong for a charger / inverter."
it is just a rudimentary illustration not a schematic. That is not, litterally, how the inverter is wired. Are you referring to the common ground wire that i did not include?
"one, you don't need a transfer swtich for most charger / inverters (any good one anyways)"
The transfer switch is already in place for the 4kw genset I removed. I am just taking advantage of what is already in place. The inverter does have "pass-thru".
"you don't power the entire boat or ac panel from an inverter. it needs to be split up into inverter and non inverter loads"
what then do you do with a/c loads that you want to be able to run off both inverter and shore power
? Like the water
heater for example? When I am at the dock
(with shore power)and want to take a hot shower
I dont want to strain the house battery and inverter.
"you certainly don't power the charger / inverter from the inverter"
Yes, I am aware of that possibility. Having a big boat and playing with all these complicated toys is no place for ametures and idiots.
"don't screw around with ac if you don't know what you're doing."
I am not a marine
electrician but I did stay at a Holiday Inn Express Last nite...in all seriousness. I am not an idiot. I hired a marine electrician to: 1. inspect my wiring and clean up any problems and 2) do all the significant and complicated wiring and installations. I am just trying to educate myself so I don't do something stupid and dangerous...like try to charge the house battery...with the house battery. Thanks for you input!
