Solis IntelliHome 16kWh 51.2V Wall-Mounted Low Voltage LiFePO4 Battery
The Solis IntelliHome 16kWh is the largest low voltage storage battery in the SolisStorage range: a single unit that collects what the solar array produces during the day and releases it as the sun goes down. With 16kWh it covers the evening and overnight consumption of a whole house without having to parallel several units. The format allows wall or floor mounting, so it suits a plant room as readily as a garage.
The cells are lithium iron phosphate, rated for more than 6000 cycles and an expected life of about ten years, with a depth of discharge of 100%. For this model Solis declares a maximum charge and discharge current of 157A, about 8kW at the nominal 51.2V, and gives no peak figure above the continuous rating: the battery works flat, with no short-term overload. The figure that counts in the installation remains the lower of battery and inverter, to be checked for the specific pair being installed. Running several batteries together calls for a combiner box or a busbar, to be planned separately.
Two things the installer must know. Early deliveries of this battery do not include the connectors to the inverter: two M8 ring terminals have to be crimped onto the power cable, for S6-EH1P(3-10)K-L-PLUS, S6-EH3P(5-18)K02-NV-YD-L and S6-EH1P(12-18)K03-NV-YD-L alike. On top of that, any inverter built before April 2026 needs a firmware update before commissioning with a SolisStorage battery. Installation must be carried out by qualified personnel.
