My trailer has the batteries in front and the plugin in the back. I installed the shunt in the battery box in the front and hooked one end to the NEG of the battery and the solar panel/trailer load box to the other end of the shunt as well. I also hooked power from the POS to the shunt B1 and the midpoint of the two 6v batteries to B2.
My question is. there is a power supply in the rear of the trailer that has AC input from outside plug to a PC type power supply that has 12V cables that go directly into the power box also in the rear of the trailer. I think that ALSO charges and tops off the batteries in the front.
will this work correctly? will it show charging via this PC style AC power supply?
