Battery Storage

EnPower Star ARO HV (High Voltage) Battery

Sleek, powerful and reliable, the EPS ARO HV battery series is carefully engineered to deliver a high life cycle (>6,000 cycles) and excellent performance with flexible capacity options (6.6 kWh to 19.8 kWh) per module. Each module can run up to 8 units in parallel for a max capacity 80 kWh of storage.

LiFePO4 batteries are the safest lithium batteries available on the market to date. Our batteries are fully protected by a battery management system (BMS) that regularly monitors each cell to ensure safety and performance.

What You will Get?

UL 1973/UL 9540-Certified.

All EPS products are UL-certified to guarantee compliance with the highest standards of quality, as well as safety for both workers and consumers.


The CPUC’s Self-Generation Incentive Program gives consumers rebates for installing energy storage systems. Access SGIP and get back ~30% of the cost of your new EPS system.

25 Year Warranty

All EPS products are protected by a 25-year warranty, which covers defects, damage, and problems.


The use of phosphates avoids the high cost of cobalt, reducing the cost of the LiFePO4 batteries.


Flexible capacity options: 6.6 kWh to 19.8 kWh.

High Cycle Life.

ARO HV batteries have a cycle life of >6,000.

Safety & No Thermal Runaway.

Unlike other battery technologies, LiFePO4 batteries have an excellent safety record with the lowest amount of reported cases of thermal events.

Superior Chemical Stability.

LiFePO4 is one of the most stable chemistries for battery technology, also featuring great energy density.

Sustain the Environment.

Our batteries are cobalt-free, fully avoiding environmental concerns associated with using cobalt.

Smart & Reliable BMS

EnPower Star Energy Storage Systems feature a smart Battery Management System (BMS) that forms part of the inner circuitry of the ESS.

Our BMS offers:
