Xantrex and cable sizes

[Dorn Hetzel]

It's not true that you can't make the wires thick enough or parallel enough of them to work. I don't know how many it would take, but you can find various tools for computing voltage drop in a given wire at a given current in amps. Ask Xantrex how much voltage drop is acceptable and parallel wires until each carries an amount of current that doesn't result in too much voltage drop. Then decide if the bundle of wire is too thick too deal with

Steve,



That was 115' total wire.



It's only 22' feet from inverters to the Batts. Via inside of rail

mounting. It's really a Guestimation, could be a little more or less.



Or four wires of 22' each. 2 Pos. 2Neg. 2 wires per inverter/charger



Not really so far fetched. with the exception that it will not work:{



Like so many things Looked good on paper.



At this point in the installation I've decided to put the new units

in the origonal inverter box inside the engine compartment.
