I am in So Cal in a town where the city takes there own cut and thus electricity prices are ridiculous (Real rate calculated by taking bill and dividing by KHw is nearly $0.5 / kWh. I bought panels at 24 panels at $120 / 380 Watts call it $3K for nominal 9120 Watts but my real production is about 7800 peak 85% not bad. I bought an EG4 18KV off a guy who had planned to go off grid and an EG4 battery ~15Kwh battery to go with it for call it $8K. Another $2k in installation costs (12 panels on the flat patio cover needed angle brackets and welded up a angled patio cover on the side of the house for the other 12, some wire, flex, connectors, breaker to tie it to the panel. All in about $13K. Tax incentives cover ~1/3 so real cost is $9K. New california law only pays me $0.038 per KWh and charges me $.50 no wonder all the solar companies are going out of business. No way am I going to put power back into the grid at those prices.
My bill dropped from $400 to $150 / month. (My previous solar install under the old rules did drop to zero with no battery install required since the utility was paying me at the same rate they were charging. I get that there are infrastructure costs, but there is no way that infrastructure costs are 93% of costs. (In fact they publish that generation costs are 60%, pay us 60% and everyone would be happy)
Saving $250 month gives a payoff time of 3 years. This makes sense to me with the crazy rates in this city. It also insulates somewhat from future rate hikes. If your rates are in line with US average (about $.25) the payoff would double to 6 years.

You set this to provide your electrical load with solar and charge your battery at the same time. If the battery goes down a certain percentage or during cloudy days with solar not producing the power you need then the inverter will automatically switch to your grid. It will not send energy back to the grid if your batteries are full or your solar is producing more power than you need.
As a battery backup newb, I really appreciate the clarification. I live in Florida and want something for a few days backup after hurricanes take power down. I don't plan on going solar anytime soon, so I want something that will charge from the grid (preferably, off-peak).
This looks like it will work well for what I want.
Can this support a couple of HVAC systems (3 ton, 1½ ton)?
Still, it is really high!
100 Ah x 51.2V = 5.12kWh per battery; 4 batteries x 5.12kWh/battery = 20.48 kWh total. Other comments on here discuss why this # isn't exactly the same as useful capacity, but ya, it's a good amount of storage.
A google search says the average single-family home in California uses 28 kWh a day. If you have solar generation that generates roughly that amount, I'd imagine that these batteries would hold enough energy for the average house's overnight energy use. Once this stuff is UL-listed, these deals will become grid defection kits.

Curious on this as well. Do I need electric company to turn off the power as well while working on this?
EG4 went through a similar thing. It has to be on the nameplate.
You're not going to get these permitted. For some people that doesn't matter.
