Default RT Inverter Upgrade

My wife has suggested getting the Insta-Pot, and she could use it in the RT and home. I am looking at this with a 750 W Inverter. I have read the Pot runs at 700W, but somehow I question this; if it did, I am under, but real close to max out. I really don't want to go to having a major electrical upgrade to accommodate this one item....we can damn well do without it. Can I ask your recommendations - I know enough to get into trouble, but not over a Pot!. Ron

I assume you have enough battery capacity, for 1hr cooking you will need 130Ah lead acid battery just to cook and a way to recharge. https://www.wholesalesolar.com/99494...-150ah-battery

The RT likely has the Tripplite inverter? If so it is a modified sine wave. They tend to not give full power to a lot of things, but a cooker should be all resistive and be OK. The inverter usually have quite a bit extra capacity for shorter times, so startup surge should also get by. You will probably be using about 75 amps or more, though, if the 700 watt rating of the cooker is correct. They often exaggerate a bit, so could be less.

At near full load, it will be noisy and fan running wide open, I think, so make sure all the ventilation is clear.

As always, thanks for the assistance. The Brochure shows 2 6V AGM 2400V Batteries...and I have four in this one - remember seeing a Decal saying something about solar ready. Due to health, we don't stay out long, so I wasn't concerned about solar package. The wife just thought it nice to be able to stop and "cook up" a meal when we are out and running. Ron

4 house batteries should be around 400ah capacity - very nice

I'll try to add to the great points already posted:

1. There would be no problem running it while plugged in or if on generator power.
2. The Insta Pot initial heavier power consumption phase (to get hot) could be done while plugged in (before leaving campsite for example), or on generator, or with the engine running + inverter.
3. The RV Tripp-Lite unit's Overpower feature is up to 150% of rated power for up 1 hour - something like 1100 watts on the 750 watt RV inverter unit.
4. The modified sine wave output of the Tripp Lite might cause the Insta Pot clock / timer to be wrong so you have to look at your watch to get accurate cooking times.

The 3 qt model is 700w.
That's the one most RVer use.

You are pushing it with a 750w inverter. (is that continuous? or max?)
you will need at least a 1000w inverter to be on the safe side.

This is more than a resistive device -- it is a computer controlled pressure cooker.

If it has electronic controls in it, there is a very good chance the Tripplite will mess it all up. It very well could do a safety shutdown of the cooker because of the pressure cooker part of it.

I was thinking it was a crockpot type cooker, which folks us all the time when driving in their vans, but they aren't pressure and not electronic controls.

FYI... most of the new crockpot in the market have electronic controls now.
It is not easy to find one with the old timer knobs.

The Instant Pot is the current rage in RVing. Several people I know have gotten them and we are considering the 3 qt. Instant Pot for our travels. It seems to do just about everything and being a pressure cooker as well it uses less energy just because cooking time is less. It is all electronically controlled. With a 2800w pure sine wave inverter and 800ah lithium ion battery bank the energy use is inconsequential.

We currently use a crock pot with simple dial controls. It is 120VAC and use it as a slow cooker. Often times (twice on our last trip) we prepared stew like pots or pork for shredded BBQ and slow cooked it all day by placing and bracing in the galley sink. The meal is ready on stopping at the end of the day. We did that with our former Great West Van because the TV and dedicated inverter with outlet for it was accessible at the galley. In our Advanced RV every 120vac outlet is hot all the time. With either van, while driving, charging input outstripped the energy use for the crock pot.
