Hi everyone,
I recently got a multi-cooker/steamer & plugged it in to my friend's off-grid electrical system. Friend has a 1500w inverter hooked up to his system. We blew the inverter when we plugged the steamer in. :frown2: Turns out he had his freezer plugged into the inverter as well & the steamer itself is 1200w. I found that out after I dug the steamer box out of the trash later that night. Oops, had no idea a $30 appliance could be 1200w! When we tried to plug the steamer straight into his gas generator it bogged down immediately on startup so we unplugged it. He got a new inverter, but is obviously not keen on me plugging my steamer into his off-grid setup again.
That said, we still need to use this steamer off-grid. So, I was thinking about getting a heavy duty inverter & trying to run it off my 7.3L diesel "generator" >:)
But now I'm cautious about damaging things there too: batteries, wiring, possibly the alternator or even another inverter. I've read about electrical devices like this surging up to 50% over their stated wattage on startup.
I'd like to be able to run the steamer off-grid for around 30 minutes, ideally an hour.
Any recommendations?
Thanks :)

can't find a propane steamer or use a propane cook top ?

you are basically running a the equivalent of a small AC cooling unit and while his inverter should have been overload protected most inverters that can handle that wattage need a massive battery bank to keep going ( my camper has 4 batteries and an inverter that can handle the load you're dealing with but I still fire up the generator when the wife wants to blow dry her hair
lol

a decent generator may be a better answer


if you do use your truck i would imagine you would need a better alternator so you can stay at idle and an upgraded alt to batter lead and +to+ cable ( the inverter should be powered off the battery directly)

the downside is a load inefficient 7.3 generator running the whole time your steaming

Gonna take 200w minimum solar panel, charge controller, 2-4 100amp hr batteries, inverter minimum for that thing. Plus enough sun 4-8hrs of good light. Other than that I would use a generator. there are some good Yamaha ones that are few hundred less than Hondas and just as good. The Hondas have a great reputation but their price shows they know about it lol. plus very fuel efficient even on low/high settings.

Thank you ZMANN, White_Buffalo7.3, & Justin0009,
That's all very helpful info. :smile2:
What are some decent battery brands & models?
I've heard a lot of good things about Interstate & Optima over the years. But will truck batteries be able to handle drain from a 1200w device for 30 minutes to an hour?
Or do I need to be looking at dedicated deep cycle batteries?
Thanks again!

I would get dedicated deep cycle batteries. In dealing with RV's over the years, I've never had good luck with 12V deep cycles as they almost always lasted 18 months - 24 months max before they were toast. Currently I have two Trojan 6V deep cycles in series and they've been great for probably going on 8 years. They are big and heavy though. Cheers!

is this a steamer, like a cooker? 1200 running watts is also not the max peak to kick it off.

have you considered a campfire steamer that works off of heat?
