Enphase will release a new off-grid battery in December that will be half the price of the current battery, don't buy anything from them before then. Look at Pika Energy. We are installers and they just got acquired by Generac, we're Generac dealers also so it comes under one roof for us. The Pika product line is well thought out, DC coupled, does Zero Export very nicely and uses Panasonic batteries. It's easy to expand from two to six batteries, They have an interface to Generac RXS transfer switches which lowers the cost of transfering. Looks like a mature product line. If you have the ability to export to the grid, Sonnen makes a good product which we have installed, uses Sony batteries which are bulletproof. We have achieved Zero Export with a Solar-log 1200.
