Let me begin by apologizing if I’ve provided too much information or my lack of knowledge is too apparent. I’ve recently replaced a destroyed diesel engine
on a Catalina 30
MkI with a Thunderstruck 10KW electric-drive. The previous owner mounted both wind
and solar electric
generation on the boat
, although based on examination of the overall wiring
in the boat
, I do not fully trust the wiring
or system designs.
The boat has two separate battery
banks, a 12-volt house bank (2x6-volt 190Ah AGM) and a 48-volt propulsion
bank (4x12-volt 105 Ah AGM). While the boat is at the slip, it has 24/7 stable 30A shore power
to charge the battery
banks (Xantrex Freedom HF for the house bank) and a separate one (Thunderstruck 48-volt charger
for the propulsion
bank), so battery charging
is not an issue in port. When away from the slip, the boat has 2x120 watt solar panels
(managed by a Blue Sky Solar
Boost 3000i solar charge controller) and a Primus wind
turbine to generate power to charge batteries
I believe both wind and solar are currently designed/wired to charge only the 12-volt house bank.
What is the best way to connect these systems on the boat so that they complement each other and not interfere with each other?
I believe the only option to charge the propulsion bank underway would be to utilize the Xantrex inverter
to provide AC power for the 48-volt charger
, or to have a portable generator
(Honda 2200) for longer cruises. Utilizing the Xantrex inverter
seems inefficient to me, is there a better way?
