From the pictures it looks like its just a battery and no inverter. So you would probably need a separate inverter for it. But i think its something simular to a tesla power wall, that you would connect to a grid tied inverter or a hybrid inverter and then so on.

The capacity is only 4.8kWh so would only provide a ~6% charge for a model 3(77 kWh battery).

I was curious how long it would take me to make up the cost (not including cost of installation) and plugged it into gemini. Came out that it'll take about 3 years to make up the cost. I'd guess about 5-6 years if you can't install it yourself. That assumes an average rate of 15 cents/hWh at super off peak, and 35 cents at peak times. My area has exceptionally high rates, so most of the country wouldn't be as significant. During summer months my rate is over 60 cents, so might actually take me more like 2.5 years not including installation.

Here's the breakdown:
Based on one full cycle per day using 80% of the ECO-WORTHY 48V 100Ah battery's total 4.8kWh capacity, it would take approximately 3 years to make up the $840 purchase price through energy arbitrage.
Savings Breakdown
With a price spread of $0.20 per kWh (saving $0.35 - $0.15), your daily performance would be:
  • Per Day: $0.77 (Based on discharging 3.84 kWh)
  • Per Week: $5.38
  • Per Month: $23.38
  • Per Year: $280.32
Payback Period
  • Time to Break Even: 1,094 days (Approx. 2.99 years).
  • Remaining Value: Since the battery is rated for 6,000 cycles, you would reach the break-even point with roughly 4,900 cycles of life remaining, during which the energy shifted would be pure profit (over $3,700 in additional potential savings over its lifetime).
Key Efficiency Assumptions
To achieve these numbers, you should account for a few technical realities:
  • Round-Trip Efficiency: Most LiFePO4 battery systems lose about 10-15% of energy during the charge/discharge process due to heat and inverter conversion. This may extend your payback period by 4-6 months.
  • Hardware Requirements: This calculation only covers the battery cost. You will also need a compatible 48V Hybrid Inverter to manage the timing of the charging and discharging, which adds to the initial investment.

Also, assumes the price of electricity will stay the same over this time. All indications would be an increase in price of electricity, making payback likely less and the "pure profit" part more significant.

Very good point. Definitely unlikely for prices to go down although prices are already outrageous

Hello fellow so-cal resident 😂, your numbers are about spot on, i did the same math a few years ago, and had about the same ROI on a small diy solar panel system and 7kwh diy battery for peak shaving. Cant wait for the summer peak rates to kick in 🤬

Does this have an inverter that can schedule battery charge to off peak TOU hours?

seriously. F SDGE. Prices are absurd. If I could do the install myself, I'd probably go for the DIY route, but I just don't feel confident when it comes to electrical stuff. Did you also have to buy the hybrid inverter?

Indeed, it's pretty nutty how large EV batteries are. I wish V2H was something more EVs supported.

They really need to, why own such a large battery for a single purpose when it could easily power your home for days
