Hi Y'All - I'd like ask for feedback on the following:

Current Situation): My wife and I have lived in an upper floor condo in SW Florida for 17 years. I5 years ago I bought a small 2800W propane generator that we stash in the bottom of a coat closet and set up on our balcony for a couple of days when the power is out following a storm. I had an electrician install a NEMA L14-30 box on the balcony and wire it to a 10-circuit manual Reliance transfer switch so that I can selectively control various 120V circuits.

We've only had to use it twice in 15 years and it did a good job of keeping our refrigerator running during the day. At night we just don't open the refrigerator, run a bedroom ceiling fan and a few LED lights. This setup works for 2-3 days.

I chose propane because I won't store gasoline indoors - after the propane tanks are filled they're stored in an outdoor shed. I'm not getting any younger and I dread dragging them up several flights of stairs to swap them out on the balcony as they empty.

Proposal A): Replace propane generator with a refurbished EF Delta Pro which I can buy relatively inexpensively on e-Bay - I need the 30A AC port for connection to my manual transfer switch. I'll have the same electrician handle any necessary rewiring and will charge the DP via house power.

Expansion Proposal B): As they become more cost-effective, I'd like to add several portable solar panels on the balcony to take advantage of the additional charge if an outage lasts more than a couple of days.

Does this approach make sense to you? Is there a better alternative I should consider? Thanks in advance...

If you need this about twice every 15 years, I don't think there is better alternative. Of course you could invest in beefy battery, but if it's staying unused for 99.9% of time, I see it waist of money.
Why you need to swap tanks (out of disaster events), are they leaking?
 
Delta Pro seems to have a horrible reputation for reliability these days and getting refurb one sounds like you'll soon be dealing with RMA process.

Thanks, Kmin - these are 20 lb tanks like are used on barbecue grills - they last about 10 hours or so and have to be replaced when empty; 2-3 days = 5-6 tanks...

Thanks, Bruce- My experience with refurb products is that they have to go through much more QC than when first built - I'll post if I have a problem...

Ok, I see.
20lbs propane has about 120kWh of energy. Generator has efficiency about 20-25%, so about 25kWh. With 2.8kWh generator that doesn't modulate well, you get 9hours. The problem is that if you only need to power refrigerator, ceiling fan, led lights, cell phone charger.. you need less than 1kW and if your generator doesn't modulate, you consume 3x. Best option would be modern ~1kw generator that can run 2-3days with 20lb tank.
I don't see solar battery solution smart choice for storm backup, no sun, no power.

Sounds like he'll be able to better utilize the propane generator by rapidly charging the Delta pro, then shutting off the generator until the Delta pro battery drops down to a level where he needs to run it again. So he will no longer have idle losses from hours of coasting at prob 200W or less.

The good news is if it does fail on you you'll still have your existing propane generator setup.

That's good if that battery can take 2+kW charge from generator. Otherwise it would be useless middle man in the setup
