The ALPHA 5 PRO supports CAN/RS485, making it compatible with many popular inverter brands, simplifying upgrades, reducing extra components, and enhancing system performance and reliability.

Instant Monitoring with Smart Display

Monitor your battery effortlessly with our PC monitoring software. The 3.5-inch smart touchscreen provides instant access to live data, individual battery status, and system settings. LED indicators on the front panel show battery SOC, operational status, and alarms, ensuring you are always informed and connected.

Essential Backup Energy Power Outages

The ALPHA 5 PRO Server Rack Battery offers a robust 5120Wh. When dealing with power outages, the ALPHA 5 PRO supplies a continuous 100A charge and discharge current, offering a dependable, efficient, and safe power solution to prepare you for any situation.

Unlock 76.8kWh of Energy with Flexible Expansion

The ALPHA 5 PRO is expandable with up to 15 units in parallel, reaching up to a total of 76.8kWh. 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

Power up quickly with three flexible charging options: LiFePO4 battery chargers, solar panels, or generators. From off-grid living to emergencies, keep your home energized and ready for any situation.
