En-sem-ble AC battery storage

The IQ8 micro inverters are now available and I've seen all the Adverts from Enphase to change over. The inverter operation is quite simple as it is now just acting like a transfer switch when the grid goes down ( or you shut off your main breaker ) it keeps the supply of AC going. So the storing of AC is new to me and if anyone wants to jump in here to shed some light on this I would appreciate it..

    If you want to store AC you need their AC battery, which runs around $2500.  It's small (~1kWhr.)

    But in reality, isn't it a box wrapped around a UPS ? (Charger, battery, inverter, transfer switch)

    Not really Mike, you have to spend another 2,500 for to get this 1.2KWH of useage. I may be mixing this up with solar edge that needs a transformer if you have 120 vac loads. Both of these systems half baked at this time, to me....way too small to be useful compared to an off the shelf genset.

    I agree with you totally. After looking at a few Hybrid systems now, I don't like how Enphase has taken an easy DIY system with mini Inverters at the solar panel and are now defeating that purpose by making a very complicated machine. Since the Inverters are at the panels, I would think just a transfer switch on the panel going either to the mini inverter then to the 240vac breakers, or going to a DC controller. On my system this would be easy to do as my panels are 250w and compatible to my emergency 24vdc system. This won't happen as I'm happy with what I have now.
