48V 100Amps Stackable Lithium ESS

The Rolls ROL‑S48‑100STACK‑LV is a scalable 48‑volt lithium iron phosphate (LiFePO₄) battery module offering 100 Ah (5.12 kWh usable energy) in a stackable format engineered for Canadian residential and light‑commercial energy storage systems. Built to meet high safety standards — including UL 9540, UL 9540A and UL 1973 — it features a robust internal battery management system (BMS) that protects against overvoltage, undervoltage, high current, low temperature and over‑temperature conditions. With a compact size, parallel‑connect capability (up to 8 units) and CAN bus/RS‑485 communications, the module integrates seamlessly with modern hybrid inverters, solar controllers and backup systems. Designed with cold‑climate readiness and long‑life performance in mind, the ROL‑S48‑100STACK‑LV offers up to 6,000+ cycles at 80% depth‑of‑discharge — a solution built for durability and future‑ready storage installs in Canada.
