48V LiFePO₄ Battery · 16kWh · IP67 All-Weather
The EG4 314Ah All-Weather is EG4's newest wallmount battery platform — 16kWh nominal (12.86kWh recommended usable) behind a 200A continuous discharge rating, an LCD touchscreen, and an IP67 enclosure rated for direct outdoor installation. It drops into existing 280Ah-form-factor systems, adds an emergency stop and automatic self-heating, and is built for a 10,000-cycle service life.
Next-gen wallmount capacity with drop-in compatibility for existing 280Ah form-factor installs.
Continuous discharge power up to 10.2kW, with a 250A battery breaker and 12.8kW of peak power for 3 seconds.
Rated for 10,000 cycles at 0.5C and 80% depth of discharge, with a 15-year design life behind it.
An onboard LCD touchscreen for local diagnostics, plus WiFi/Bluetooth connectivity for remote system visibility.
Internal heating keeps the cells within charge range through cold weather, protecting both performance and lifespan.
A physical rapid-shutdown control adds a manual safety layer on top of standard BMS protections.
Rated for direct outdoor installation, with the flexibility to wall-mount or floor-mount depending on the space.
A high parallel ceiling for serious capacity growth well beyond a single module.
This is EG4's newest wallmount battery line, built as a capacity and durability step up from their 280Ah generation while keeping the same physical form factor — it slots into existing 280Ah-based installs without a redesign, using the same quick-connect terminals plus an added bolt-style terminal for ring connections where needed. New BMS functions carried over into this generation include WiFi/Bluetooth connectivity and active cell balancing, on top of the LCD touchscreen and E-Stop.
At 16kWh nominal (12.86kWh recommended usable at 80% DoD) with a 10,000-cycle rating and a 15-year design life, it's built for long-term daily use. The IP67 enclosure covers direct outdoor installation, with the option to wall-mount or floor-mount depending on the space available, and up to 32 units can run in parallel for large-scale storage on a single platform.

Certifications (UL1973, UL9540, UL9540A, UN38.3) are listed as pending on this product's own spec sheet — confirm current status before publishing. Application: residential, commercial, off-grid, backup.
This battery needs a compatible inverter to function. Closed-loop communication partners differ by installation type — grid-tied installs pursuing UL 9540 certification have a narrower list than fully off-grid installs.

It's EG4's newest wallmount platform, built with new BMS functions on top of their 280Ah generation — WiFi/Bluetooth connectivity, active cell balancing, an LCD touchscreen, and an E-Stop — while keeping the same physical form factor and connection style.
Yes — EG4 built it in the 280Ah form factor specifically so it can slot into existing installs without a redesign, using the same quick-connect terminals plus an added bolt-style terminal for ring connections.
Per this product's own spec sheet, UL1973, UL9540, UL9540A, and UN38.3 are all listed as pending. Certificate of Compliance and Certificate of Conformity documents are available to download, but full listing status is worth confirming directly before treating certification as final.
Yes — it's IP67-rated, built for direct outdoor installation, with the option to wall-mount or floor-mount depending on the space.
It's rated for 10,000 cycles at 0.5C and 80% depth of discharge, with a 15-year design life, backed by a 10-year (or 10,000-cycle) manufacturer's warranty.
Given the voltages and currents involved, installation should be handled by a qualified, licensed electrician or solar installer familiar with your local code requirements.
