Summery is that Tesla powerwall is the best option of you want to add a battery? Works with all systems since it's AC coupled and works as backup when there is an outage. Price is good as well.
Always good to do some calculations. If your battery solution costs $10,000 and is 10kWhrs in size and lasts 4000 cycles (that's about 11 years) then the capital cost to you is 10000/10/4000 which is 25cents per kWhr. This worth thinking about especially if you charge the battery using off-peak electricity. If your off peak grid electricity is, say, 30cents per kWr then your battery electricity is going to cost you 55cents. Charging from solar PV makes a lot of sense. Then your cost per kWhr is back to 25cents (excluding capital depreciation of your panels). As for switchover on a grid power outage; in most systems that switchover duration is milliseconds. However, I don't believe house battery systems claim to be a UPS (uninterruptable power supply) (Could be wrong). Either way, for sensitive electronic equipment in your house it would still be wise to connect those devices to the power using a UPS because they will guarantee zero off time on power outage, suppling power to your devices for those vital milliseconds while the house battery system flicks over from grid to battery.
Wow, this Segway Portable PowerStation Cube Series sounds like a game-changer for outdoor enthusiasts like us! The massive capacity, fast recharging, and waterproof technology make it perfect for camping trips. Plus, the smart app control is a cool feature. I'll definitely check it out for my next adventure. Thanks for the recommendation!
The Enphase 5P might be a great alternative - given its higher enery output (3.84kW sustained) and warranted 15 year life - as a modular, stackable battery.
Looking for an automatic transfer switch. Our battery backup is run by Growatt Inverters which can be programmed to run during certain times. An ATS which would use the inverter as the "primary", and the grid as the "failover" would do the trick. Most ATS manufacturers are focused on generator backup for the grid, and uninterested in tech support. Ideas?
some growatts have the switching capability. most of eg4 inverters have it! i just bought one with a similar purpose as you in mind. i also bought a subpanel-i’ll move most of my circuits to it but keep my ev circuit in the old breaker box. i’ll got an eg4 battery and will charge at night then run the house off the battery during the day. i have time of use where night is 4cents and day is 21+cents
15,000 cycles at the usual one charge cycle per day is... 41 years. In 41 years, maybe even 3 years, home battery tech will have improved and reduced in price.
Wow all of these are for people who know nothing about solar power and have money to burn. An honest designer should be able to build them a complete off grid ready system for half the cost per kwh.
The FranklinWH battery storage system is better than all your product reviews. It's 13.6kwh capacity, 12 yr warranty and AC coupled capabilities, combined with its industry best LFP technology, there isn't a better option available in whole home integration. Pretty disappointing you don't know your products better.

Signature Solar for more storage and less $$

That's not math 😂 they sell 5kwh for 2g and under

What about FranklinWH?
I agree, not including FranklinWH is a serious oversight. It has actually been on the market for over a year, unlike the Panasonic.
No Solaredge battery !
Exactly! FranklinWH is by far the best storage system available today

Is compatible with 3 phase circuits?
Does anyone know anything about Paladin power? A battery back up system.
Review did not even mention the walrus or Rino or Kong or Condor elite, why not receive the bigs boys under 6 k ?
There's no such thing as an AC battery. There ARE battery banks that include an AC Inverter.

forgot to say that the inverter will power the new subpanel and will be isolated from the grid circuits.
Just to be clear, there are no AC batteries. The Tesla Powerwall has an integrated Inverter.
Good info.
EG4 life power, 30kwh for less then $9,000! These powerwalls are overrated and overpriced.
EG4 for the win. 3 powerwall batteries 14.3x3 = ~$10K for ~45KW
Anyone can say their batteries will last 15,000 cycles. A more useful bit of info would be what brand & chemicals do the batteries use.

SUNPOWER’s new SunVault?
EG4 is a better deal than any of these.
