The EG4 WallMount 314Ah Indoor Battery pairs with the EG4 18kPV Inverter to give you a whole-home backup system built for indoor installation. It stores 16.1 kWh of usable energy and delivers 200A of continuous output, so it can carry real household loads, not just a few circuits.

Built for Indoor Whole-Home Backup
This system is designed for homeowners and small business owners who want dependable backup power without sacrificing indoor space to a bulky enclosure. The EG4 WallMount battery uses LiFePO4 (Lithium Iron Phosphate) chemistry, the chemistry preferred for stationary home storage because of its stability and long service life compared to lead-acid alternatives. The manufacturer states the battery includes a third-generation Battery Management System (BMS) for monitoring and cell balancing, along with a self-heating function that protects performance in cold environments.
Battery Characteristics
- Chemistry: LiFePO4 (Lithium Iron Phosphate)
- Capacity: 314Ah, 16.1 kWh usable storage
- Max Continuous Output: 200A
- Peak Power: 12.8kW
- BMS: Third-Generation BMS with advanced monitoring and cell balancing
- Cold Weather Protection: Self-heating function for cold-environment performance
Wiring & Configuration Limits
Series and parallel expansion limits for this battery are [NEEDS VERIFICATION] — not stated in the source data provided. Do not wire this battery in series or parallel with other batteries, including other brands or older EG4 models, until you confirm compatible expansion limits from the manufacturer documentation.
Pro-Installer Tip
Lithium batteries lose usable capacity and risk internal damage if charged below freezing without protection. This battery's self-heating function is designed to address that friction point, but you still want to confirm the heating function is active and functioning before a cold snap — not after. Undetected cold-charging events cause microscopic lithium plating on the anode, which shows up months later as premature capacity loss or BMS lockout. Use a shunt-based battery monitor to track charge events and internal temperature readings over time, not just voltage. As a professional standard, plan your daily discharge around 80-100% DoD (Depth of Discharge) for LiFePO4 systems like this one, and avoid habitually running the battery to absolute zero.
Key Benefits
- 16.1 kWh of usable storage per battery for whole-home or small business backup
- 200A continuous output supports heavy simultaneous loads
- Third-generation BMS improves balancing precision and response time over earlier generations
- Self-heating function extends reliable operation into cold weather without manual intervention
- Indoor wall-mount design keeps the battery out of the elements
