Power Converter Question

[trashman]

Thanks for the tips. I checked the reverse polarity fuses, and those were ok, i further checked the breakers and fuses and i found i shut off the elec to the water heater, once i flipped the breaker, the fan went on to the inverter and it started charging. So because i shut off the elec water heater element, that shut off the invertor. (i didnt want the element to go on while it was off season and winterised ). Thank you again.
