A High-Performance LiFePO₄ Battery for Versatile Energy Solutions
The EG4® LifePower4 battery is engineered to deliver high-density energy storage with unmatched reliability. Unlike lead-acid batteries, which suffer from short lifespans and frequent maintenance, LiFePO₄ (Lithium Iron Phosphate) technology offers:
- Longer Lifespan – Over 6,000 deep cycles, meaning daily use for 15+ years.
- Higher Energy Efficiency – 99% charge/discharge efficiency ensures minimal energy loss.
- Superior Safety – Stable lithium chemistry and advanced BMS prevent overheating and overvoltage issues.
- Lighter & More Compact – Weighing just 99.6 lbs. (45.2 kg), it’s easier to handle and install.
Designed for Seamless Integration
With its 100Ah capacity and 5.12kWh energy storage, the LifePower4 battery is built to support a wide range of energy systems. It integrates smoothly with 48V inverters, including Sol-Ark, Growatt, Victron, and Schneider Electric, and features RS485 & CAN communication ports for real-time monitoring and optimization.
Ideal for:
- Solar Energy Storage – Store excess solar energy for nighttime use or backup power.
- Off-Grid & Remote Power Systems – Reliable energy for cabins, RVs, marine applications, and tiny homes.
- Home & Business Backup Power – Keep essential appliances running during grid outages.
- Scalable Commercial Storage – Expand energy capacity for large-scale operations.
Certified Safety & Durability
When it comes to energy storage, safety is just as important as performance. The EG4® LifePower4 is built with:
- Dual Fire Arrestors – Prevents fire hazards with advanced flame-resistant technology.
- Emergency Stop (E-Stop) Function – Instant shutdown for additional safety.
- UL 1973 & UL 9540A Certified – Tested for thermal safety, fire resistance, and reliability.
- IP20 Protection Rating – Designed for indoor installation in controlled environments.
With these protections in place, the LifePower4 battery meets the highest industry standards, ensuring safe operation for residential and commercial applications.
Scalability & Expandability
Need more power? The LifePower4 battery is modular and scalable, allowing you to expand your system as needed. Connect up to 64 batteries in parallel, reaching a total capacity of 327.7kWh.
This makes it an excellent choice for:
- Large homes needing off-grid power storage
- Businesses looking to lower energy costs
- EV charging stations needing high-capacity power reserves
