Inverter recommendation for 100aH deep cycle battery?

[wahoowad]

I have an Ionic 100aH LiFePO4 battery for my boat trolling motor but would also like to use this battery for some portable power when camping. This battery has a max discharge current of 100A so conceivably I can get 1200W out of it, although I would never pull anywhere near that much. I'm thinking maybe a 500 - 750w inverter? I really don't have any high drain appliances - at different times/trips I might be powering an inflatable air mattress pump, sometimes some lights, recharging devices, maybe running a mobile Starlink. So not a lot of watts but thought I'd get something capable of running a home fridge during a power outage. What's that - 400W continuous, 700W surge?

Any recommendations on a decent make/model that has held up for you?

There are a lot of good quality inverters, if you are going to be charging electronics be sure it is a pure sine wave type.

I am a little Bias towards Victron, I have beem running my victron inverter (and many other components) for about 2 years now and have had 0 issues with them. I know redarc is very good as well. You are going to soend money if you want the least amount of wasted energy. Hopefully you have a way to charge on the go like a portable solar panel. Inverters will have a constant draw on top of the inefficiency going from dc - ac. would recommend trying to get everything off of 12v to run direct off the battery. You can find 12v > USB chargers and 12v air pumps pretty easy that will be more power efficient than an inverter.

As for the fridge i think 100ah for that is going to drop pretty quick, if you dont open the fridge it keeps the air. Youll have to figure out the ah pull of the compressor when it kicks on and figure out what is needed to keep that going (as far as inverter output).

Another vote for Victron. Most of this technology was perfected in motor homes and travel trailers years ago. Victron has been there for decades. Inverters and DC-DC converters also. Their prices reflect the actual market where the others jumped on the overland band wagon and charge more for the same thing.

i bought a modified sine wave 3000w inverter from harbor freight over 10 years ago and moved it into our teardrop about 4 years ago and it still works fine. the pure sine wave inverters are the way to go now and the prices are lower than they were when they first hit the market. i would go with a 2000w inverter and that way you can power larger items if you ever need to in the future. i go 12v on everything and have the inverter for items that i cant get in 12v, like the wife's hair dryer and my water pik. i also like the higher capacity inverter for "just in case"...
renogy has a 2000w pure sine wave inverter for $260. it is cheaper than victron, but i cant attest to quality of either. i just think its better to drop a few extra bucks and get a higher capacity unit...2000w will run an induction burner, a hair dryer and possibly things in the future that arent thought about right now. i know from experience that everytime i bought something...i always end up having to get the bigger size.

Exactly. Your current battery won't run a 2000W inverter, but don't let a $200 battery be the limiting design factor for your system! For $200 you could buy a 2nd battery and push 2400W if needed.
IMO, the main items I want 120v for in a truck camper are an electric kettle, 1200-1400w usually unless really weak and crppy. And an induction burner, 1400-1800W is standard for anything not 1-star. Other possible items are a small 700W oitput microwave, which uses 1100W and needs a 1500W inverter to actually run.
