Description
The HELIOS Series is a utility-grade, outdoor-rated LiFePO₄ battery engineered for whole-home backup, microgrids, and C&I retrofits that demand high usable energy with fast, clean installation. A sealed, weatherproof cabinet houses a 51.2 V, 314 Ah pack with an advanced BMS and front-service layout, so it can live outdoors beside the inverter without a separate battery room.
Designed for closed-loop communication with leading hybrid inverters, HELIOS delivers stable voltage, high round-trip efficiency, and stout surge handling for motor starts and clustered loads. The architecture supports straightforward parallel expansion via a high-current internal bus, making multi-battery scaling simple.
For installers, the cabinet provides clear cable landings, front HMI, integrated disconnects, and labeled comms ports to shorten commissioning and keep inspections tidy. For owners, cobalt-free LFP chemistry and rigorous safety testing translate into long life, dependable performance, and low maintenance.
