I have an off grid cabin ready to be energized my question is regarding my inverter I have a 3000watt inverter / 480watts of solar panels / 30 amp transfer switch / 4-250 amp hr batteries / 3000 watt back-up generator / 400 watt fuse between the battery bank and inverter / 8 circuit breaker panel box so the inverter states that it supplies 60 volts to 2 single wires to hardwire to panel box but that the nuetral is not to be connected to the common ground so does this then dictate that the 2 single supply lines that each carry 60 volts get wired to the black and white(nuetral) wires in my panel to energize the panel to a standard 120 volts?

Before you do anything with this inverter please run the model number by us first due I did noted about connection format I want to double check it due you mention 60 volts per leg so I want to make sure before I can able tell you the correct connection before something will damaged it if not carefull.

And the fuse you say 400 watt fuse or you saying 400 amps which one it is ?

Merci,
Marc

Oops my mistake the fuse is 400 amp typed it in wrong the inverter is a GP3000HD that is designed for rv use originally thanks

Oops didn't send the fuse is 400 amps my mistake the inverter is a GP3000HD primarily used in RV units Thanks

Ahh ok IIRC the black will go to the black junction point you should able follow the circuit what it have build in receptales { but watch the circuit arrangement some case you may have two circuits on 120 volt side }

The white will be at netural juction point.

And with this model it is a modifed sine wave so just be aware some electroic stuff WILL not run properly with it.

Let me grab the PDF it should be simauir what it you will have that set up.

http://www.pvpower.com/pdf/datasheets/go%20power/mobile_power_guide.pdf

scroll down about half way you should see the transfer switch that what it should be connected.

as far for ground just bond it from inverter frame to panel ground.

I will have to dig up little more with the inverter / converter regulations to make sure you are ok on that part.

Merci,

If the neutral is not at the same potential as ground (you say it's actually at 60V), you can't really use this inverter safely with a hard-wired electrical system. Panels are not designed to have any voltage between neutral and ground. Even when set up with an isolated neutral bar (as in a subpanel), the neutral bar is not expected to be at high potential and is not properly insulated for it.

That true but one way or other the OP have to concat that manufacter to verify the inverter connection to make sure they are ok with 120 volt supply as long the OP use the proper transfer switch as the link I posted above.

And to OP if you try to read the voltage with DVM it will not read correct at all due the chopped wavefourm if you have true sine wavefourm the DVM will read it correct.

Merci,
Marc

Thank-you so much for all your input. Great to have access to so many Professionals. This system will be treated the same as an RV system looks like the transfer switch sorts everything out.
