Hi John,
Let's look at the usage of the system related to the charging needs.
The house bank has the most draw. The starting bank, should be able to
start many times without needing a charge. The battery switch if used as a
(1 -2 - all) should allow you to combine the house and the starting bank(in
any configuration). In this layout, most of the need for charging should be
on the house bank (solar and wind). The alternator should be attached to
the battery switch (controlled by the switch position) to select the battery
bank that you choose(house or starting or both) for your charging needs. I
don't know about your 110v charger. Mine will do both banks and has
attachments for two bank connections.

Subject: [Liveaboard] Electrical systems install
Dear list I am helping a friend install solar panels and wind generator and
a new alternator. We have a plan but I would like to ask you if it sounds
like a GOOD plan.
1 The house bank is 430 amp hours (4 6volt golf cart batteries) they are in
the port cockpit locker and a starting battery is in starboard
2 The wind generator WINDBUGGER is mounted on the mizzen with a 8 gauge
wire. It is 30 ft to the comp. It goes to a 50 amp diode to another 25 amp
breaker to the NC25A Charge controller. From the charge controller to the
house batteries there is an additional 25 amp breaker. (This is according to
the diagram that came with the Charge controller).
3 Instead of the 1-2-both-off rotary switch we have installed a dual circuit
battery switch (on-off-combine) made by blue seas, as well as a battery
combiner (called a automatic charge controller)
4 Instead of running the 100 amp alternator to the common post on the old
rotary switch, we put it to the house bank
Our questions are:
A. We have a 40 amp multi stage charger for 110 where do we put the battery
charger wires?
B. Is it correct that the wire from the wind generator goes to the house
bank?
C. The two 50w solar panels are lead to another charge controller (a
Morningstar 6amp) and then straight to the House bank is that correct?
D. Is there a problem with charging from 3 sources, can anyone of the units
burn out (mainly we are worried about the solar panels) because of the power
coming from the other charging sources
This is how far we have come. Man there are so much to think about and
neither of us are electricians so thanks so much for the input
Regards John Miami
