Xantrex Freedom 458

Having a problem with my electrical system none of the a/c outlets work with shore power plugged in, power coming from shore power into inverter to the main breaker panel. Both of house batteries are dead does anyone know if the inverter requires some DC power to close some kind of relay to allow AC power in before I remove the inverter from the system.
The inverter is also a battery charger I bypassed the inverter and the AC outlets work fine would like to use the inverter/battery charger any inputs would be helpful

Re: Xantrex Freedom 458

Yes. Some of them need dc to allow the ac to pass through. Generally they will contine to let ac pass through once it starts. And you can disconnect battery

Ie if you jump 12v to the inverter for a few seconds the ac will work.

The inverter should be after the main ac panel so the inverter is breakered as well. But that is a different issue

If the batteries are totally dead you might need a different way to charge. The inverter / charger probably has safety features so it won't charge a supper dead battery

Another battery and jumper cables may bring the voltage up enough for the charger to kick in. (Once you rewire it back together)

Re: Xantrex Freedom 458

How did you "bypass the inverter?"

Does this model have a built in automatic transfer switch?

How have you wired it? IIRC, many of the combined I/Cs have multiple methods of wiring, i.e., subpanels, main panel, etc.

My Freedom 15, for example, is wired so that all AC loads are covered by my inverter, but I manage the loads downstream of the I/C, i.e., water heater is never on when the Inverter is on. Other wiring options include NOT having the water heater on the inverter output.

Need more info from you to answer the question, not sure I agree with the previous answer at all.
