I'm running four 6V batteries and a 2000W inverter. I use them to power my microwave for about three minutes only to heat a cup of something. I don't think I'd use it for ten minutes. Do you have four batteries or only two?

I have 2 Group 27s deep cycle. Looking like this may be more than I thought just to run it for 5-7 minutes?

As long as you realize the most likely path will be a significant battery upgrade that is fine. Some do seem to manage on two batteries.

Don’t expect to cook dinner, run the furnace all night and wake up to make coffee on inverter also.

You could run it for the 10 minutes on the two 27s IF they were fully charged to start with, but then you also have to get through the 24 hr day running the furnace etc until the next gen hours lets you recharge the batts.

With four 6s or four 27s and being able to recharge the batts at least every day (but only need solar each day in summer in the open for that--needs gen in winter under trees) can run the MW for 10 minutes to do spuds, then right after, 5 minutes to do frozen veggies. Meanwhile steaks get done RVQ outside.

The 15 min of MW time at 120a is not what matters with the four 6s. You still have to run the furnace and watch movies on those same batts.

It is all about scenario. When do you do this and how often? When are gen hours if any? Got any solar? Is there any sunshine in the forecast?

Good idea to run the gen to run the battery charger/converter while also using the inverter to run the MW. Different 120v source plug- ins of course--don't want any 240v!!!!

Same thing on 15 amp shore power if that is what you have at somebody's house you are visiting or at a fairground for dog trials. The converter input "supports" the inverter draw from the batts so it is not so hard on just two 27s for that 10 minutes. Means the 10 min is during gen hours in that scenario.

For 10 minutes, start the generator. Pay me now or pay me later.

It is all about understanding what uses what & smart power management. You are not at home with limitless power availability.

A genny running your charger is the fastest way to restore power to the battery bank. Run the genny at meal times when you might also want to use the microwave. That is also the time to be sure that anything rechargeable is put on charge.

Run the genny for a few hours in the morning till the battery bank is fully charged & when the CG does not have many around with people leaving or headed out for the day. Maybe doing the same as you. If everyone runs their gennys together, for the same reasons, nobody bothers anyone else with the noise.

I'm just curious, what takes 10 minutes in a microwave?

If you regularly use that kind of power and don’t have a recharging source like a generator or solar, you likely won’t get them recharged while towing. The generator is still the way to go.

Not true if you are using a DC-DC charger !

I suspect if he had the knowledge and skills to install a DC-DC charger, he wouldn't be asking this question. A DC-DC charger is not a stock item.

About the only thing my cook uses the microwave for, & they take awhile, is baking potatoes.

Otherwise the microwave is used to store bread.

Thanks. I tried that, and I have to say I prefer the regular oven. Of course that takes 2 hours.
