The EG4 WallMount 314Ah Indoor Battery pairs with the EG4 6000XP Inverter to give you whole-home backup power in an indoor-rated enclosure. It stores 16.1 kWh of usable energy and delivers 200A of continuous output, enough to run essential circuits or a full panel depending on your load setup.

Why This System Matters
Indoor lithium storage batteries like this one are becoming the standard for homeowners who want backup power without dedicating a shed or garage bay to it. The chemistry is LiFePO4 (Lithium Iron Phosphate), which is the same cell chemistry used across most modern home battery systems for its thermal stability and long cycle life. This unit is built for indoor wall or floor mounting, not for marine, RV, or golf cart applications.
Battery Characteristics
- Chemistry: LiFePO4 (Lithium Iron Phosphate)
- Capacity: 314Ah / 16.1 kWh nominal energy
- Enclosure Rating: IP20 (indoor use only)
- Mounting: Hybrid wall or floor mount design
- BMS: Third-Generation BMS with advanced cell balancing and monitoring
- Cold Weather Protection: All-Weather Self-Heating function maintains performance and battery health in cold environments
Wiring & Configuration Limits
This battery is cross-compatible with other EG4 battery models, allowing you to scale storage capacity by adding additional units to an existing EG4 system. Auto-ID technology automatically recognizes and syncs new batteries into the system during installation, simplifying setup.
Not compatible with: This is an indoor-rated (IP20) unit — it is NOT designed for outdoor, marine, or unconditioned garage installation without additional protection. It is NOT a starter battery and should not be used for engine cranking applications. [NEEDS VERIFICATION]: maximum number of batteries per system stack and series/parallel wiring limits were not provided in source data — confirm with the manufacturer specification sheet before designing a multi-unit stack.
Pro-Installer Tip
Lithium packs stacked into a whole-home backup system are unforgiving of mismatched batteries — mixing a new 314Ah unit with an older EG4 pack of different age or cycle count invites imbalance between packs, which stresses the weaker unit's BMS every charge cycle. Confirm firmware and pack age compatibility before paralleling multiple units, and let the Auto-ID sync fully complete before applying load. Verify pack voltages and balance with a shunt-based battery monitor at commissioning, and again at the six-month mark. Because this is LiFePO4 chemistry, you can plan around 80-100% depth of discharge for daily cycling without the shortened lifespan lead-acid systems suffer at similar DoD levels.
Key Benefits

Compatibility & Fitment
The EG4 WallMount 314Ah Indoor Battery is cross-compatible with other EG4 battery models for expanded storage capacity, and is designed as a pairing with the EG4 6000XP Inverter as sold in this bundle. It is intended for indoor residential or small business backup power applications.
This system is NOT rated for outdoor or marine installation without additional environmental protection. It is NOT a drop-in replacement for golf cart or RV battery banks. Standard lead-acid chargers are NOT recommended — this battery requires charging equipment compatible with LiFePO4 BMS communication protocols. [NEEDS VERIFICATION]: specific charger/inverter communication protocol details beyond the bundled 6000XP were not provided in source data.
