This extensive capacity is ideal for large-scale operations, emergency backup power, or off-grid energy. It effortlessly meets your highest energy demands, ensuring reliable power when and where you need it most.
Premium Grade A Cells for Long-Lasting Battery Life
The ALPHA 5 PRO features premium Grade A cells known for their exceptional safety, lightweight design, high energy density, and durability. With over 7000 cycles at 80% Depth of Discharge (DOD) and a 10+ year lifespan, you'll have long-term reliability with minimal maintenance.
Smart BMS for Unmatched Protection
The ALPHA 5 PRO guarantees safety and reliability. The advanced Battery Management System (BMS), with a built-in circuit breaker, protects against overcharge, over-discharge, over-current, short circuits, high/low temperatures, and rare hardware failures in high-voltage solar charge controllers. Even with physical damage or excessive thermal exposure, the ALPHA 5 PRO will run as cleanly as before.
Reliable Power in Extreme Weather
The ALPHA 5 PRO is built to handle extreme temperatures, operating safely from -4°F to 140°F. It stops charging below 32°F and discharging below -4°F, with an auto shut-off when temperatures exceed 140°F. You're guaranteed consistent performance no matter the conditions.
Easy Installation with Rack-Mount Design
The ALPHA 5 PRO features a 3U rack-mount design, fitting seamlessly into server racks. Its robust sheet metal casing ensures durability and strength, while the removable carry handle simplifies transport and installation.
The Ultimate Replacement for Lead-Acid Batteries
The ALPHA 5 PRO provides all the energy you need in a compact battery. It's eco-friendly, with a 10+ year lifespan. It's the smart, efficient choice for energy storage featuring a BMS for added safety and real-time monitoring.
Three Charging Methods for Maximum Flexibility
