question--why invert command on Xantrex Freedom 458, 20 amp inverte/rcharger remote control panel fails to activate the four ,six volt golf cart house batteries, to convert from 12 volt DC to 110 AC ...
What are the voltage readings on the two wires feeding the Xantrex? Check it as close to the inverter as possible. My guess is the mechanic hooked the Xantrex wires up incorrectly and it is only getting 6 volts.
