[RE-wrenches] Adding battery backup to Enphase

[William Dorsett]

I talked with Enphase tech support a couple months ago, and he expected their AC Battery to be out 2nd Q 2016 at an unknown price. It is designed primarily for load shifting so isn’t big… maybe 1 kWh which you stack like you do inverter/module pairs along a trunk cable to whatever capacity you want. If it’s like their other hardware, I expect it to be well thought out and am looking forward to being an early adaptor.

Esteemed wrenches;

I have a new client who has convinced himself the world as we know it will be ending in the next few months. He has ~6kW of Enphase and wants to add battery backup for critical loads.....quite a few of them. I recommended he buy some Kill-a-Watt units and start to monitor kWh usage. 

My first thought was the new Enphase "AC Battery system." Is this even available for purchase yet, and if so has anyone here tried it? I'm thinking ease if compatibility, tech support, warranty......

Otherwise will likely AC couple a new inverter.  I was thinking an Outback Radian, and lithium batteries (looking at Iron Edison) as my prediction is they will be mostly sitting idle for the next 10 years at least. Any pitfalls, horror stories, and no-nos anyone is willing to share? Crossed off NiFe; my house runs on them and they are fairly high-maintenance, as I predict this client will be.
