Direct Current PV heating

As you know, there's no mechanical Arc Suppression in the bimetallic thermostats designed for AC so they would have to be bypassed or set to maximum (and not relied upon) and replaced with a DC contactor controlled by an additional thermostat. I would have expected this to still come in under the cost of an inverter as well as delivering greater efficiency.

 

12V invertors are a total joke. 100 Amps or more to get anywhere close to a kilowatt is madness! If you found a 48V off-grid invertor, that might make sense.

Yes, never thought of that.

See what I can find in the 48V range.
