Hello fellow cruisers
I am designing the charging
system surrounding my upcoming conversion to EP. I have included a simplified diagram of the system.
My design requires a few things to work
that I am not certain will; thus I seek advice
from more experienced system designers and solar
The system will have two 48V banks, one in each hull
, to power
said hulls respective pod-motor. There is also a 24V house bank in the bridge-deck that is already in place and operating satisfactorily. I intend to redirect all solar charging
to the 48V banks to take advantage of the larger arrays each charge controller would be able to handle. The pod motors will be able to charge their respective bank with hydrogeneration when the boat
The 24V house bank would be kept topped up by the 48V banks.
First question: Can I use a solar charge controller to safely charge the 24v bank from the 48V batteries
? It seems like it would work
but I would like to hear of anyone successfully doing this in their own installation
Can I use a 0 1 2 switch to effectively select which, or neither, of the 48V batteries
controllers are seeing? The charge profile would be the same for both banks. This is necessary so that I can direct all charging to one bank or the other if one or the other is full or they are out of balance.
