7,000+ Charge and discharge cycles at 80% depth of discharge for long-term use.

76.8kWh Total capacity when expanded with up to 15 units in parallel.

10 Years Warranty backed by a 10+ year designed service lifespan.

Product Overview

The ALPHA 5 PRO 51.2V 100Ah LiFePO4 Battery is designed for energy storage builds where battery performance, usable capacity, and long-term reliability matter. It is a strong fit for solar storage, RV power, marine electrical systems, cabins, commercial installations, and backup power upgrades.

Built with premium Grade-A cells and an advanced battery management system, the ALPHA 5 PRO delivers stable output, strong thermal and chemical stability, and low maintenance over thousands of cycles. The 3U rack-mount design and RS485/CAN communication make it easy to integrate into clean, system-ready solar and off-grid installations.

Wide Inverter Compatibility

The ALPHA 5 PRO supports CAN/RS485 communication, making it compatible with many popular inverter brands. This simplifies upgrades, reduces extra components, and enhances overall system performance and reliability.

Instant Monitoring with Smart Display

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

Unlock 76.8kWh of Energy with Flexible Expansion

The ALPHA 5 PRO is expandable with up to 15 units in parallel, reaching a total of 76.8kWh. This extensive capacity is ideal for large-scale operations, emergency backup power, or off-grid energy — effortlessly meeting your highest energy demands with 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 7,000 cycles at 80% Depth of Discharge (DOD) and a 10+ year lifespan, you get long-term reliability with minimal maintenance.

Smart BMS for Unmatched Protection

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 under physical damage or excessive thermal exposure, the ALPHA 5 PRO keeps running cleanly.

Overcharge Protection Helps protect the battery from charging beyond safe operating limits.

Over-Discharge Protection Helps prevent the battery from being discharged below safe voltage levels.

Short-Circuit Protection Built-in protection helps guard against short-circuit and overcurrent conditions.

Temperature Disconnects High and low temperature disconnects help protect the battery in demanding environments.

Built-In Circuit Breaker An integrated breaker adds an extra layer of protection against fault conditions.

LiFePO4 Stability The battery chemistry is designed for strong thermal and chemical stability.

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 — guaranteeing consistent performance no matter the conditions.

Easy Installation with Rack-Mount Design

The ALPHA 5 PRO features a 3U rack-mount design that fits 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 delivers all the energy you need in a compact battery. It's eco-friendly with a 10+ year lifespan — the smart, efficient choice for energy storage, featuring a BMS for added safety and real-time monitoring.
