A three-module 15 kWh tower suits a household already exporting a good share of its generation; six to eight modules make sense where there is an EV on a cheap overnight tariff, electric heating, or a desire to carry a whole evening's load without importing.\u003c\/p\u003e\n\u003cp\u003eThe modular design is the point of the range. Solis builds each unit as an independent module, so a stack that starts at 15 kWh can be extended later by adding modules rather than replacing the system.

Solis rates the series for a depth of discharge of 90% or more and more than 6,000 cycles, which the manufacturer describes as an average service life of around ten years.
