That just depends on how it is wired. In my motorhome the microwave oven works on the inverter if that is the only available power source. The power for the inverter can come from the batteries (which doesn't work very well) or the main engine alternator. The water heater and air conditioners are not wired to the inverter.

You need to be a touch more specific.

On my RV I use a portable Induction cooktop and it works fine on the TRUE SINE inverter or generator or shore power.

I know if I buy another TT, I will ask for a propane DELETE ! 1000w-2000W PSW inverter, probably four 6V golf cart batteries and a 2000W generator (or maybe 2) and you should be all set.

Boondocking would require some good solar and generator use for hot water and to be sure the batteries were up for the evening. Good insulation and heated mattress pad will get you through most cool nights. If you boondock below freezing, you will still need a propane furnace. Non-vented propane heaters release too much moisture to be run overnight.


I am thinking seriously about moving from 4 golf cart batteries to 4 Renogy 12V 100ahr lithium iron batteries. The only thing holding me back right now is $3200.

It is never a good idea to run an unvented heater in a small space when everyone is asleep. A lot of things can go wrong.

Your Inverter ALWAYS works from the coach batteries. All the Engine Alternator does is resupply the energy lost from the batteries. If your Inverter does not work very well when the engine is OFF, then you have a problem and that needs to be fixed. Doug

Tiffins do NOT run off the Inverter. Doug

Even if it could run on the inverter (mine will) I crank the generator whenever the DW is going to use it for more than a couple minutes. Instead of depleting the batteries you are charging them with the generator. Same thing for the microwave as it’s a high amp appliance.

A big MH needs a couple hours of generator each day to keep the batteries charged when dry camping.


This post is my opinion (free advice). It is not intended to influence anyone's judgment nor do I advocate anyone do what I propose.

Lots of info. Yes we are looking at coaches again after selling our Zephyr a few years ago. We have never had an induction cooktop before. The coaches we are looking at have built in ones. Wife brought the question up. All coaches are used and are hundreds or thousands of miles from us, so a demo is out until we get there. It's not a deal breaker either way, just curious. We are VERY experienced with battery power and inverters. etc. Have just never had a induction cooktop. Searching the net hasn't helped, nor do the factory brochures or web sites. Just thought I would ask here. Thanks all.

Remember, the Tiffin Inductions require Induction cookware. Tiffin supplies the correct Cookware. Doug

Does an induction cooktop run off of the inverter or is it genset only if not plugged in.

I am referring to a cooktop in a large DP. Tiffin, Newmar, or Berkshire.

thanks


You can run it off any AC outlet that is wired to the inverter. We run the M/W off the inverter and it draws more amps than the induction cooktop.

The inverter is going to pull from whichever source has the higher voltage at that amperage. If the altenator cannot supply enough amperage then inverter will pull from the batteries. Under heavy loads my lead acids lose a lot of voltage so I only run cooking devices while one of the engines is running. And the batteries are only just over a year old. That is part of why I am looking at lithium batteries.

Well you are wrong. Tell you what, go disconnect the coach batteries and then try to run your Inverter from the Engine Alternator. Doug

I agree with Doug on this
Point of inverter connection is the batteries
The alternator simply keeps the voltage ? and hence the current a little higher

If you remove the battery from the circuit and attach the inverter directly to the cables with out the battery, it isn't going to work in almost all RVs
Certainly will not work in mine, going to need an alternator that can maintain 100+ amps at idle speed at full voltage at the connection point, with instant full amps, otherwise the inverter is going to fault and shut off
