We have 3 separate starting batteries one for each engine and one for a Northern Lights 6KW genset.
I assume the 3 bats you show on the schematic are the 3 x 4-d house bank.
How do the 3 starter banks connect into the system....ie how are they charged?
For charging we have 4 60 watt solar panels connected to a Xantrex model 35 3 stage charge controller. We also have a Sunforce 600 watt 3 phase wind turbine connected to a MPPT charge controller
The last piece of the puzzle is our Northern Lights M673L3 genset. It is wired to a MagnaSine MS200 inverter charger.
The MPPT is connected now to the center battery terminals in the house bank. the other two charge controllers are connected to the house bank via the battery switch and in the case of the solar controller to batteries 1 and 3 in the house bank.????
Your schematic doesn't represent this.
I am assuming that the unlabled box with + and - are either bus bars or power posts.
In that regard the positive bus, and the negative bus can be considered direct to battery. As mentioned the 3 batteries making the house bank should be connected pos to pos, and neg to neg, then a pos tail to the pos bus bar, and a neg tail to the neg bus bar from the opposite end of the bank.
Nothing except the bus bar tails should be connected to the batteries, with one exception.
The exception is the voltage sense wires to the charge controllers.
I do not see any voltage sense wires in your schematic for either the wind or solar. The Magnum senses voltage on it DC source.
Why are you showing a ground to the bat switch?
Remember, I said put your hand on each and every wire that goes to and from the bats, switches, and controllers. Make sure you know each beginning and each end.
Don't assume, or draw how you think it goes. Draw exactly what you have.
