These Sonnen Batteries are wonderful product. They are an AC coupled system and can currently store up to 16kWh. As with most back-up battery you need a dedicated sub-panel but they integrate easily if you know what you are doing and they have sleek looking cabinet. Sonnen answers their phones and we have found the Sonnen salespeople and engineering to be knowledgeable and helpful.
