need a positive circuit solar controller
or use a DROK voltage buck booster as an intermediate step
what i need is a charge controller that controls the V+ output
the majority of controllers use common connection for all the Plus connections and control the output via the negative side
this works as long as you can isolate panel negative and battery negative
which is Easy to do on a new install
but i have situation where i can't find and separate the negative line from an OEM solar panel wiring, old panel has been replaced
the original was 5w~10w trickle maintenance for the chassis battery, using only a blocking diode in the positive feed and the panel negative wire is tied into chassis wiring someplace, and only the positive wire was run up front to the fuse panels for connection
using a normal controller ties all the positives together, i have to use jumper wires to the negative BUS for both sides in and out and they are common, batteries in back panel hot wire up front, negative unknown
since using an isolated negative is not possible
need a controller with control in the positive side of the circuit
or maybe a voltage buck booster between the panel positive and the power connections terminal block
a DROK between the solar controller and the panel might provide isolation and voltage boost
panel into DROK (which would only function when the panel was producing power )
booster output connected to input of solar controller
we are talking a max of 90w power,
my memory from our previous discussions , says these are common neg, with the positive out put floating and controlled
which should work for this project
comments please
