This or the Pecron E3800?
For me: I buy this. Why? Because it could interchangeable with other brand inverter, solar panel, or batteries. With Pecron, you can not do that. You have to stick with Pecron brand batteries and very expensive.

Pecron E3800LFP is AIO, which is battery and inverter together as one unit. If inverter break down, you have to buy the NEW whole unit. Eco-Worthy, you just buy new inverter. Because the batteries are separate. If you want add more batteries, EW batteries are way cheaper than Pecron.

I have 4 batteries EW 280Ah 12V for about $1000. I could connect those 4 12V batteries in SERIES. It become 48V battery system, then I could add to this system. And of course, you could get any brand solar panels with this. I saw some 200watt bifacial only $60.

E3800LFP + 2 BATTERIES E3800 = $2897 (4200 watt AC Output, Battery 11,520Wh, 120V single phase)
2 x E3800LFP = $2600 (8400 watt AC Output, Battery 7,680Wh, 240V split phase)
Buy 2 of this Eco Worthy System = $2400 (7000 watt AC Output, Battery 10,240Wh, 240V split phase)
Buy 1 of this EW System + 4 x 12V 280Ah Batteries = $2200 (3500 watt AC Output, Battery 19,456Wh, 120V single phase)

I don't see a mention of UL certs. AFAIK, no UL1973 = no permits (unless your local government is incompetent and doesn't administer the NEC like they're supposed to).

This is eco worthy power station on mobile car has model no SL3500. Since it has battery pack upgrade plus inverter change, will call this as SL3500 V2. eco-worthy web site also sell the same V2 unit. However, their web site SL3500 installation menu is for V1 dated at 20250619 even this SL3500 V2 showing up in their web site for weeks.

Not necessarily incoming tech replacing, just a competitive environment for HF inverters, and a growing glut of prismatics that were supposed to feed an EV market that has stalled.

What permit? This constitutes a backup power system with no grid-tie in.

There are a number of municipalities that allow opting out for just this type of scenario. A number of others that only want to see power mast and panel up to code. It just depends where you are and what you can do.

Is the inveter available separately? I would rather have that to combine with 280ah or 100ah 48v system.

Your comment makes it clear that you do not understand what this is. An Anker or EcoFlow system needs no permits. There is no part that interfaces with the utility.

no connect to grid, no permits. just don't go to the grid, it's a racket that will never benefit you.

Not an expert by my understanding is if not UL certified then there may be an issue with home owners insurance if there was a fire or damage determined to be due to the batteries/inverter. Would just check with your own policy on that.
