This ECO-WORTHY setup is a 5.12 kWh, 48V backup system aimed at keeping critical loads running, especially lights, fridge, Internet, and a well pump. The inverter is described as supporting 240V split phase input and output, with installation typically handled through a transfer switch, interlock kit, or hardwire to a 50 amp breaker. The main limitation is runtime, since the battery is framed as short duration for heavier household loads and not suited to hot water heaters, dryers, or air conditioning for long. There is also concern that the inverter may only output 120V unless units are paired in parallel, so the voltage setup needs careful checking.

Common Questions (5)

  • It is better suited for critical circuits than whole-house loads. The 5kW inverter and 5.12kWh battery can handle lights, fridge, internet, and similar loads, but AC, dryer, stove, and water heater will drain it quickly or exceed its capacity.

  • Runtime depends heavily on load, but several comments estimate only a few hours for many homes. Light loads can stretch it to hours, while heavier everyday loads can cut that down fast; one estimate puts it around three hours for a lot of people.

    ModenacartModenacartGor32Modenacart

  • Yes. A transfer switch box or breaker-panel interlock is the safer way to connect it, because you need a proper way to isolate the house from the grid during outage operation. The inverter can be wired through a 50A transfer switch box or directly to a double breaker if the setup is done correctly.

  • Yes, it has been used as a UPS for a well pump and is described as supporting 240V split-phase output. One practical note is that some setups needed a grid-breaker reset when the unit got stuck in bypass mode, and a soft start may help with pump starting loads.

    ChrisG7990HairyButtGoblinJD713lass.richard

  • Yes. The system supports both 240V split-phase input and output, with L1 and L2 each providing 120V plus neutral and ground. It can be wired to a 50A double breaker, transfer switch box, or hardwired to the panel.

Note the inverter charger only supports 240v input from mains.

Every time I look into something like this, my head starts to spin. My mother lives in a manufactured home and power randomly goes out during bad weather. Could this be set up by an electrician to be a backup source for her? The idea is to keep lights, fridge, clocks, and maybe TV powered during an outage.

Look into a manual switch with 50 amp generator plug to a back up battery. You get can one that's 3kw and higher. It won't run the washer and dryer or ac. But it will keep all the things you listed without breaking the back. Will cost cost you a few thousand or more tho

This is exactly what it does. Yes, you should ask electrician install a "POWER TRANSFER SWITCH BOX" to 50AMP DOUBLE BREAKER of home electric panel. They charged $500 at my sister house. I know how to do it. So I do it myself. But you need to teach her how to use it to charging and power up the house.

Here is my "POWER TRANSFER SWITCH BOX or POWER INPUT BOX". Call whatever you want 😀:

Our power rarely goes out for more than an hour so I went interlock kit. They are breaker panel specific so you'll need to find out what model breaker panel she has and see if they make one for that model. This plus$200 in parts she could have lights, fridge and Internet/computer for hours. She'd have to go to the breaker box when the power goes out and turn off the main power from the poles and switch the input on, or leave this inverter on and just move some circuits to a sub panel. A lot of ways to do it depending on your budget.

My parents are on a separate meter for their well water and never had water when the power went out. I bought one of these from ecoworthy's ebay store and set it up as a UPS for their well pump. It works pretty good but there has been two times in the last 6 months that the inverter says it is in bypass mode but the well pump doesn't kick on. A flip off of the grid power breaker puts it back to inverter mode and a flip back on it goes to bypass mode and it works again.

This sounds like a classic (and unfortunately common) bypass relay fault on the EcoWorthy 5kW hybrid inverter (the SRNE-rebranded HFP/HYP4850U100-H or similar 48V 5000W model sold on their eBay store).
Contact the eBay seller immediately — EcoWorthy has replaced units for this exact bypass issue when still under the 1-year warranty. Send them a short video of the display saying bypass + output voltage reading 0 V. Several people got free replacements.
Might want to add a soft start.

If I buy this to back up my house which already has solar, what else do I need to do? Buy a power transfer switch and get it installed and that's yet?

YES, it supports BOTH INPUT AND OUTPUT 240V SPLIT PHASE.

L1 = 120V
L2 = 120V
N = NEUTRAL
PE = GROUND

Great that you have solar panel already. This system is just what you need to backup your house. And get electrician install "Power Transfer Switch Box" like mine: https://ibb.co/7twW8FNB

You could do "HARDWIRE" as well. Hardwire don't need power transfer switch box. You wired directly from INVERTER OUTPUT L1, L2, N, PE to electric panel DOUBLE BREAKER 50 AMP.

Most homes have solar that shut off when utility shuts off. So as to not electrocute the lineman working on the power lines.
