Anyone know what wattage size the inverter is in the E-trek and how do they heat the hot water?
2500 watt inverter. The hot water heater is on demand electric. There is also an instant shot hot water faucet on the side of the kitchen sink for instant boiling water.
On demand electric - how will that work? The very smallest on demand electric I can find is a 9kW unit. That would be one heck of a high current drain and this one could only provide a temperature increase of 30 degrees at a 2gal/minute flow (that is the new normal shower flow rate) and this unit was 240VAC. You could be taking a cool shower in colder weather in any E-trek.
Add it up: induction cooktop (about 1.8kW), microwave (about 1.2kW), electric on demand water heater (about 9kW if they are going to heat shower water), and then there is the air conditioner that RT has said can run up to 18 hours on batteries (no idea what the wattage of the A/C unit is). If you had just the water heater, MW and cooktop operating that could be up to a 1,000 amp (12kW) drain on the 12 volt battery bank. I can only guess at the above wattage figures since as far as I know RT has not released these figures - but my wattage numbers should be in the ball park.
