i'd also look into having portable propane, even if just for emergencies or backup.
but don't buy them at big 5 for $30 bucks if you can find them at a larger asian grocery store for 15 bucks.

[off-grid-] solar power is *battery power*, and battery power will supply *watts*, and not necessarily *kilowatts*...

As you've already seen, OP, your Jackery won't support even a 500W draw for very long at all.

For example, and this is a very extravagant setup, I'm assembling THREE 100 Amp-hour 12V batteries in parallel for 300 Amp hours of which I can only use half (150 Amp hours)... even then, I plan on pulling a 1400 watt load through an inverter (12V to 120V) for just 5 minutes at a time, and with a maximum of 5 times per day if that. That is a considerable hit on just one or two batteries.

(I tip my hat to AGGRO! for making this work; I would assume, with the engine idling to prevent dumping his truck's battery...

When I was coaching lil league I put a 2000 watt inverter in my truck with a 1000 watt microwave. I used it for years.

And rofl @ oktavist's suggestion!


My three batteries are in a little camp trailer and will be charged with 420 watts (two 210 watt panels) of solar. I will have wired also a "shore" (120 volt) charger, an 120V connection, breakers, etc and a generator should I need to throw some bulk-phase charge amps back into my batteries then let solar finish the absorption phase of charging. I hope to not need the generator at all but I will have it so that I don't damage my batteries by chronic undercharging...

You may benefit as I have from Bob S who has lived with off-grid solar-charged battery power and knows how to make these kinds of systems truly work as well as possible.

Start here with his F.A.Q.s - https://handybobsolar.wordpress.com/...ad-this-first/

Good luck to you!

I have a small camp stove that takes regular automotive gas, which in my mind is more efficient then turning gasoline into electricity then heating food with it. I bought it and a companion lantern when bicycle camping a lot in the 80's, along with a small dedicated container for extra gas. Camping for a week was no problem for one person and at the time gas was easier to find than LP where I was camping.

If I had to do a cooking option with a small generator, I'd get one big enough to power the small air fryer I use pretty much every day. Works great, light weight, easy to clean, simple construction.

I too was a die-hard unleaded stove/Lantern guy but that has changed in the last few years as I had more and more issues with the equipment. I was replacing the "generator" in the lanterns almost every year. Made the switch to 1lb propane cylinders and have not looked back.

Get the refill adapter and fill them from a a BBQ tank (And fill that from your 500Gal tank)...

It pulls ~200W, then ~450W then it shuts off when starting. This is in saute mode.
Thanks for the info. I probably won't be cooking with electricity if I have propane available. On the other hand, I think my off-grid solar setup could handle it.

Yep, that era occurred before I moved rural and got onto a 500 gallon tank with a nurse valve. LP is cleaner and easier, for sure.

What I liked about gas prior was flexibility, practically everyone encountered had gas of some sort and, unlike LP, bartering/buying/sharing was simple, just pour out what was needed.

More recently, a different version applied when the gas station was out of diesel and I needed some for the tractor; I just siphoned it out of one of the truck tanks and back in business.

Where I live in Oregon most people are all-electric and power is super cheap but when it goes out, rarely, that's it, dark ages. Good reason to have backup like discussed here. For cooking, I'd fall back to the camp stove or charcoal grill or gather some tree wood around the property and start a campfire next to the house and cook.

I went through a period of power self-sufficiency for the shop and house in CA and found it to be quite a sunk cost, even with the business writeoffs. At the time, 30 years ago, I was designing stuff like the Tesla powerwall, perhaps not as slick, but using solar to charge large capacity material handling batteries and running inverters to power the property grid with diesel genset as a backup. Over time, simplicity started to seem more attractive. It still does.
