One hundred amp hour lithium batteries were three forty nine from the off grid store in Milton. Not bad considering.

Inverters !
- Thread starter crankcall
- Start date
Has anybody seen this thing? Battery / inverter/ charger all in a box , one stop job . Charges in an hour and if the stats are to be believed runs everything I need to do without being an electrician
And it can go anywhere, .

@Scuba Steve has one (or at least one similar).
Those things are nice, and they're absolutely convenient, but they're also insanely overpriced for their capacity in many cases.
2048wh at 120v means that if you're running a ~1500w appliance (ie coffee maker) you could run it for about 1.3 hours hours before the battery is dead. Obviously you're not going to run a coffee maker for 1.3 hours straight, but you get the idea - say 15 minutes for a cycle, so you'd get 5 pots of coffee before it's dead, assuming no other loads at all.
If you're using only 100w, you're going to get 20ish hours. The math is pretty simple in the end.
But, In checking, those units are $2000.
Compare that to a 100ah Lifepo4 battery (which is probably somewhere around the equivalent capacity of what's in there) for $300ish now, and an Amazon pure sine inverter with some USB plugs built in to it (I paid something like $250 for mine), and you've got somewhere in the vicinity of the same capacity for 1/4 the money. Yeah, you'll need a charger, but I picked up a 100a Lifepo4 charger on Aliexpress for $80, and there are lower amp chargers for Lifepo4 available for <$50 if you're not in a rush. In the end is it all as pretty as that Ecoflow? Nope. But at 1/4 the cost, you could put it all into a carry tote from Princess Auto or something and make it respectable, and you're still at way less than half the cost.
Here's the 280ah (for comparison) Lifepo4 that I built and currently have in our camper. At the time this cost me around $1100 for the parts (4 cells, the BMS, wire etc) and I'm sure I could build it now for even less since Lifepo4 is coming down in price every day, but it goes to show you what you can get in capacity if you don't need pretty, and you're handy. I built it in a Princess Auto tote and just have connectors on both ends of the box, one smaller set for the connection to the trailer house loads, and bigger beefier connections on the other end for the bulk of the heavy inverter load and fast charging - 150-200a in some cases.
This is perhaps far more DIY than many would like or feel comfortable doing, but here's a prefab 100ah for $299, plus your inverter, a few wires to connect between the two (one wrench needed), and bobs your unclle, $1400 left over in your wallet.

Renogy On sale, $339. I had 2 of these in my boat, they replaced my 4kw gas genny. A ho alternator and a decent set of house batteries will ran my boat.
Eco watt thing is fifteen hundred bucks off Amazon. Based on the cycle of my nespresso ( which makes single serves ) I can make approximately 20 coffees and still charge my cell phone . And if I sell the boat it can stay with me . Looks pretty and is reasonably well made with all the BMS and overload / undercharge shutdown features built in . Problem solved for me .

They certainly have "simple and in a nice convenient package" wrapped up.
Update on my Ecoflow Delta two max battery generator. This little unit exceeded my expectations, they seem to have a good handle on adaptive thinking , cigarette jack , USB A and C , six AC plugs and will accept AC or solar charge and can be run from an automotive alternator . Extra battery cassettes can be added and the best part , Ecoflow has announced the Wave air conditioner unit , smaller than a case of beer and uses about two hundred watts somehow using a compressorless cooling tech . This battery gizmo will run AC for eight hours . Should take the stickiness out of the boat cabin for a decent sleep. Yes I could have cobbled together a system for less money , but putting AC in my last boat was a three k project alone, this is aux power and AC and I’m under three . It can move to a trailer or sprinter van if life takes me that way .

I’m interested in reading about this but anything compressor less than I’ve ever heard of is either a swamp cooler type set up or a peltier module, neither of which provide any sort of meaningful cooling. Unless there’s some fancy new technology I haven’t heard of yet.
I have a compressor based 2250 BTU mini air conditioner in our camper that runs off of our inverter and will run for about 10 hours straight on my lithium battery bank, and although there is not a hope in hell of it cooling the entire trailer with that few BTU, I point the air outlet directly over top of the bed and it provides a nice cool breeze all night long for sleeping which gets the job done - we’ve spent many a night in pea soup conditions comfortable as could be with no generator needed, and then we just recharge the lithium battery from the car next day while enroute.
It's R290 so not compressorless. 6000 btu so 0.5 tons. Seems similar to portable a/c with ducting to dump hot air. The most convenient but least efficient way to cool a space with a compressor.

yes as usual , the info I got from the first saleguy was incomplete . I did vist TruGrid solar in Milton ( where they are very knowledgable ) for more info. The website is a bit vague on internal tech , as the guys there said , lots wont understand it anyway. Its a mini reversable heat pump, can switch from AC to heating , uses R290 refridgerant . Rated 6000 btu can drop a 100sqft space 15deg in 20mins . Runs 8hrs on its own internal battery which has a recharge time of 1.5hrs , longer on solar but thats an option.
on sale for $1100 cdn so not the cheapest thing , but the portability is interesting . I think if I doing a trailer setup I would look at a more RV specific unit ( like you see on most trailers now) , but only rooftop , the wall units have a history of leaks into the wall and ultimate failures.
In the last decade , options for reliable solar panels / wind gen sets/ hydro generators has boomed.
Friends on an Island camp have reliable high capacity AC power using a plug and play Battery inverter generator setup that was under ten grand, About 25% of the cost estimate to run an underwater cable . New spin on this , insurance companies are now looking at people to install an engineered plug in system with built in monitoring and safety , there have been enough claims of home made Edison experiments the rules are changing

Just for your info in your enclosed floating bedroom, R290 is propane. Only 0.25 lbs of it though so even if it leaks, you shouldn't be able to blow.
Propane ? This I did not know! This is why I come here , for info and advice from folks that know stuff I do not .
And to find out anyone that ever voted liberal is a F’wit, but mostly electrical and hvac stuff which I’m not good at .

I have run "propane" refrigerant in older cars after repairs, the DIY stuff they sell at CT, PA, etc. marketed as R12a (not R12) et.al is basically propane. IME it works much better at cooling than the "proper stuff".
Just make sure to label the port to not contaminate some techs AC recovery gear in the future...

Read the fine print on those numbers. They're often perfect world, ie an R2000 room in the shade and the AC only running at 25% duty cycle.
Real world is usually vastly different results.
Used a ton of that stuff back in the day.
Do they even make R12 anymore? Pretty sure I’d heard that any old R12 cars now had no choice but to retrofit.
I had to recharge my daughters Subaru a few days ago and was happy to see that the new 123YF refrigerant is now available cheap in these refill cans now as well. It was insanely priced at one point.
As a start temp drop is based on cubic ft not square feet. Also very affected by humidity levels (and especially change in humidity). Almost every sales quip is complete garbage and should be ignored.
As a rough calc, 100 sq ft with 8' ceiling dropping 15 degrees (I'm assuming Fahrenheit), in 20 minutes without changing humidity is (800/20)*1.08*15=700 btu. Seems plausible that by the time you added solar gain, pumping conditioned air out, (Which means warm air infiltrates) heat escaping from exhaust pipe, humidity reduction, etc the number the sales guy used might be reasonable.
I’d suspect it’s was tested , somewhere in a lab in the Quong Dong province , inside a tent ,set up in an R two thousand room , that was already air conditioned….
