Re: freedom 2500 watt inverter
Re generator size (2800 watt)
Probabley not. When the generator is charging the batteries it it must also handel the AC loads. A 2800 watt generator will barely handel the possible 2500 watt AC load that the inverter can - let alone adding a 150 amp charger to the load. ("A freedom 2500 has a built in 150 amp charger and transfer switch" from spec sheet)
(150 amp X 14.2+ volts = 2130 watts and then you add power loss in the charger of est. 20% so 2130 watts /.80 = 2262.5 watts just to run the charger.)
You should look at a 5000 watt range generator or a control unit that limits the generator draw to a user specified level and makes up any short fall using inverter power while charging. (Note that the charging circuit will not be drawing maximum power at all times but the AC system must be capable of providing max. power when required.)
I hope this is not confusing to you and will help you out.
I didn't want to just say get a larger generator without a reason.
