Off Grid and Gas Furnace

Singlemalt Member Posts: 3
Living off grid, pure sine inverter delivering 120 volts.

Would like to install a forced air gas furnace with a modern control circuit board.

I've been told if I can get 120 volts AC to the furnace it will run no problem.

It has been suggested that I would be subject to spikes and surges that would take out the solid state board.

I'm having no TV, Computer, or high end washing machine issues now so can't see how the furnace should have a problem.

I can't find any installers who have installed a gas furnace on an off grid electrical system.

Any comments or experiences would be helpful.

    What kind of inverter do you have?

    some of the older modified squarewave designs wreak havoc on certain controls.  The newest of the new tend to be less susceptible than many from the past decade or so.

    Phantom load would be a concern for me.  I do not have a source for reliable information on that.
