Everyone talks about the "ideal" situation where house bank is physically located in the same space.
Sure it'd be great to locate all my batteries
in one physical space, but unless I go to lifpo, I can't do that. Maybe in about 5 or so years when this bank dies, lithium will be a real price
competitor, but until then, it will have to wait.
That being said, I'm having a hard time finding out how people are wiring
a house bank that is located in two separate locations.
I know that cable lengths between the two banks should be "equal" lengths, along with the interconnects being equal lengths. I'm wiring
up 4, potentially 5 firefly batteries
, 2 in each location(or 3 in one, 2 in the other). The distributor i'm working with is giving me a good deal and due to work
i've done with them in exchange for discounts.
That being said, heres a very basic schematic i was thinking of doing for my wiring. The unswitched bar will also have my MPPT
controllers and my inverter/charger as well(connected via fuse & service
Bar to ACR to Starter - 2/0
to bar - 2/0
Inverter/Charger to Bar - 4/0
Bar to House Switch - 2/0
BOTH House bank to Bar - 4/0
My biggest question is regarding the alternator
and how it will charge the two banks. The alternator is a Balmar
100amp externally regulated with mc-614. I have two battery
temp sensors, one for each bank as well.
Anyone have thoughts on this?
