Enphase storage & grid protection

[ncs55]

I found this from enphase. http://www2.enphase.com/global/files...ed-Systems.pdf And this has been discussed before in here. https://www.solarpaneltalk.com/forum...78-ac-coupling The best article I found concerning ac coupling with enphase is here. http://www.civicsolar.com/support/in...rid-pv-systems

Personally, I am not sold on the Enphase solution yet. It is still new and not proven in the field as of yet. Just my opinion. For Going hybrid I would consider first what are your exact concerns and needs, doing your homework on the products available and reliability factor, what their features are and how to design and integrate them into your existing system affordably. Personally, I would consider adding something like The Conext SW or XW inverter with a solid battery bank that is matched for your load profile when the grid is down. The SW is a newer inverter line that is smaller and more affordable than the XW units. I am not sure if the Enphase system can be AC coupled with either, but I know that a Sunny Boy can be AC coupled with the XW. Also when you are considering making your system into something that it was not really designed for. You will need some type of transfer switch to shift the power away from the grid and to your critical load center when the grid goes down. Transfer switches are pretty costly. XW's have internal transfer switches and I think the SW's do as well. If you are serious about going hybrid it will cost a little bit of money to achieve a robust and reliable system and may involve abandoning enphase all together to achieve what you want. We are having great success with the XW inverters and the 600V charge controllers and or AC coupling with SMA's. It is a costly system but works flawlessly and can accept generator input which we think is necessary to have as a backup source. On that note the SW can accept a 120V generator input and give you a 240v output which can come in handy even if you do not normally need it.

I am having issues configuring my de 5548 ac coupled with enphase micro inverters. My main concern is related on how to charge the batteries. And I was reading some document from enphase that they don

Enphase only produces micro inverters, they do not work at all with batteries

Enphase has an "AC battery" solution that's available now but is pitifully small (270 watts out max, 1.2kwhr.) LiFePO4 based. They can be daisychained.

What's an AC battery?

Never mind. I found that battery. It is a play on words. It is really just a LiFe DC battery system with an AC charger built in.
