Community Reviews

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.

    Big22JD713ModenacartModenacart

  • 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.

    JD713HairyButtGoblinModenacartJD713

  • 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.

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.
What happens if you do hardwire if power goes out. It goes directly to the battery until the battery runs out?

Over an 8hr period how much could this honestly put out, watt wise, continually without overheating?

This is about a three hour backup for a lot of people. Not nearly enough to be considered a backup system. If you have lots of power outages you probably want about 24 kwhr. This will just get you through minor outages.

Most homes have solar that shut off when utility shuts off. So as to not electrocute the lineman working on the power lines.
I think you mean most solar systems shut off grid supply when power goes out and only users power generated for charging batteries and local consumption, otherwise you would lose power too.

Have you ever use GAS/PROPANE GENERATOR to backup your house during power-out? It's the same method as gas/propane generator. When power-out, you TURN-OFF MAIN BREAKER of the breaker panel. Why we have to turn-off main breaker? So when we run gas/propane generator or ELECTRIC INVERTER, the electric-worker doesn't get shock if they work nearby.

WHEN POWER OUT:
  1. TURN MAIN BREAKER OFF
  2. TURN HVAC AND ELECTRIC HEATER OFF, because your inverter only 5k watt is not enough power to run it. And battery will not last long.
  3. TURN BREAKER THAT INVERTER CONNECT DIRECTLY ON, AND TURN INVERTER POWER ON.
WHEN POWER BACK: Do opposite direction above

JFC do not follow this advice. Get a transfer switch. You don't want to be in the business of shutting off your main. If you forget, you may kill people.

Nope. My solar completely shuts off during a power outage and doesn't even charge the batteries. Called the installer and that is how it is supposed to work. Imagine my shock when i found out about this. Although i have to say that i added my batteries after the solar so maybe if they were all installed at the same time it would act differently

Add another battery, prolly in a separate order, for another $725ea...or $635 I see (multiple listings for same battery)? Pretty good for another 5120Wh and a clean setup. You could do worse for $1628. Most well pumps are 240V, so the MPPT needs to output that to support; this does. Does anyone know standby drain? If you have 400w solar panels, how long does it typically take to charge 10240Wh? is the math simply 10240/400W (assuming SPs are actually outputting fully)

are we sure this is 240v? Just looking at the inverters they sell the ones that look like this are 120v

Each person has different idea. I just used my knowledge to help out, not for debating. But when someone comment like this, I knew exactly what type of person this is. Who ever think his idea is work for you, then go ahead buy a "TRANSFER SWITCH" and call electrician install for you. See how much it will cost. I give you Home Depot link transfer switch right here: https://www.homedepot.com/p/Relia...-n/a-_-n/a

If you a person can not able to remember turn off main breaker, when you come to breaker panel. You could ask electrician install "INTERLOCK KIT" on breaker panel like this: https://ibb.co/PZSp8Tx1

Even electrician install "POWER TRANSFER SWITCH" at my sister house cost $500 and don't even install interlock kit. But my sister still know how to turn off main breaker. Screen shot my sister panel breaker below.

Your installer screwed you royally. I would blast their name out there so others don't get screwed too.

This battery will likely not last eight hours.
People really need to do some monitoring of their own power consumption. My house at idle with me asleep with no ac or hot water heater running consumes 0.5-0.75 kw/hr. This would only power my house on idle for maybe eight to nine hours, while I sleep. Add in an AC and you add 1.5kw to 3 kw. Add in a hot water heater and add 4-5 kw. While awake add at least 0.5 kw. Add a dryer and add 4-5 kw. Add a stove and add 4/5 kw. If you start doing some basic math and you can easily see a 5 kw battery will last a very short time. This battery cannot power a hot water heater for an hour. The advice on this thread will at worst end up with someone dead, at best with people who are very unhappy their "whole house backup" is dead in an hour or a few hours. Only an idiot would take solar and battery backup advice on slickdeals, including my advice. If you want to get good advice, go to a forum where people do real diy solar and backup systems. You are going to have to do so work to know what you need. Most homes need at least 24 kw of storage to last 24 or more hours. Good luck.

Always depends. My electric waterheater uses about 3.5kwh per day (every day for the past two years). Lights on and watching tv on a laptop with a home server, still using 650w. 15kwh gets me about 12hr of regular daily living. That's with oven and cooktop use. Clothes dryer is another story and that will kill my battery fast. Things is that for an emergency situation i can milk the batteries out for days.
Those other forums are a much better place to get good ideas. But you might find something good here every once in a while.
