The EG4 PowerPro is a 48V LiFePO4 wall-mount battery built for home backup and off-grid storage. Rated capacity is 280Ah, or 14.3kWh of usable energy. It carries UL1973 certification. This page covers what you need to know before you wire it into a bank: chemistry, discharge limits, and how it fits into a series/parallel system.
Note: If you would like to review the manufacturer Product Specifications, Warranty, Brochure, etc., for this system, please refer to the "Resources (System Manuals and Warranty)" Tab above on this page.
E-E-A-T Intro
Home battery storage lives or dies on two things: honest capacity numbers and correct system wiring. The EG4 PowerPro is a 48V LiFePO4 unit, UL1973-certified, sized at 280Ah / 14.3kWh. That certification matters — UL1973 is the standard testing lab shorthand for stationary battery safety, and it's one of the things an installer or inspector will ask about before sign-off. Beyond the headline numbers, the manufacturer data provided to us does not include BMS amperage limits, cycle life, dimensions, weight, terminal type, or operating temperature range. We are not going to guess at those. See the Resources tab for the manufacturer's full spec sheet before you finalize a design.

Wiring & Configuration Limits (Series/Parallel)
Manufacturer-published series and parallel expansion limits for the EG4 PowerPro were not included in the data provided to us. Do not assume this unit can be stacked to a specific number of units in series or parallel without confirming against the manufacturer's installation manual. [NEEDS VERIFICATION]
NOT confirmed for: any specific series count, any specific parallel count, or mixed-brand/mixed-age battery banking. Do not combine this battery with lead-acid batteries, other lithium chemistries, or older/used LiFePO4 units of unknown cycle history in the same bank.
Pro-Installer Tip
Lithium banks fail early for one avoidable reason: someone assumes a manufacturer's series/parallel limit instead of checking it. Wiring beyond the BMS-rated series count on a wall-mount unit like this can trigger BMS lockout or push individual cells outside their voltage window, causing irreversible cell imbalance over time. Before you design a bank around the EG4 PowerPro, confirm the exact series/parallel limit and continuous discharge rating in the manufacturer's manual (see the Resources tab), and validate real-world performance with a shunt-based battery monitor rather than relying on the inverter's built-in state-of-charge estimate. LiFePO4 chemistry generally tolerates 80–100% depth of discharge, but confirm that figure against this unit's documented cycle-life testing before you plan your daily draw around it.
Key Benefits
- LiFePO4 chemistry — no acid, no off-gassing under normal operation, longer service life than lead-acid at equivalent Ah.
- 14.3kWh of usable energy per unit for home backup or off-grid loads.
- UL1973 certification supports code-compliant residential installations.
- Wall-mount form factor for stationary installs (garage, utility room, mechanical closet).

Compatibility & Fitment
This unit is a 48V LiFePO4 wall-mount battery designed for home backup / off-grid storage applications. Charger compatibility details (charge voltage, recommended charger type) were not provided in source data — confirm with the manufacturer's manual before commissioning. [NEEDS VERIFICATION]
NOT confirmed / NOT included: This listing does not include an inverter, charge controller, mounting hardware, or interconnect cabling unless explicitly listed as a separate line item. Standard lead-acid chargers are NOT recommended for LiFePO4 chemistry without confirming charge-voltage compatibility. This battery is NOT rated as a vehicle starter battery. Do not mix this unit with lead-acid, AGM, or gel batteries in the same bank.
FAQ
