EG4 48 Volt 16 kWh 314Ah Outdoor Wall-Mounted Heated Lithium Battery (UL9540A) is a high-capacity energy storage unit designed for residential and light commercial solar systems that require outdoor installation and verified fire safety testing. This battery is engineered to provide reliable backup power and energy storage while supporting year-round operation in varying environmental conditions.

Operating at a nominal 48 volts with a 314 amp-hour capacity, the EG4 16 kWh battery is compatible with a wide range of hybrid, off-grid, and grid-interactive inverters. Its outdoor-rated, wall-mounted enclosure allows installation outside the living space, helping simplify system layout and conserve indoor room. An integrated heating system supports battery operation in cold climates by maintaining suitable internal temperatures for charging and discharging.

Key Features:

• 16 kWh Energy Capacity: Supports extended backup runtime and solar self-consumption.

• 48V, 314Ah Configuration: Designed for standard low-voltage battery systems.

• Outdoor Wall-Mounted Enclosure: Weather-resistant housing for exterior installation.

• Integrated Battery Heating: Enables cold-weather operation and charging.

• Lithium Iron Phosphate Chemistry: Stable chemistry designed for long service life.

• UL9540A Tested: Evaluated for thermal runaway and fire propagation behavior.

• Scalable System Design: Can be paired with additional units to increase capacity.

The EG4 16 kWh battery includes an internal battery management system (BMS) that monitors voltage, temperature, and current to support safe and stable operation. The outdoor design makes it suitable for installations where indoor battery placement is limited or not preferred, while still maintaining compatibility with common inverter platforms.

This battery is well suited for solar backup systems, hybrid energy setups, and off-grid applications that require dependable storage capacity with fire safety testing aligned to modern code requirements.
