The Rich Solar ALPHA 5 PRO is a 51.2V 100Ah LiFePO4 server rack battery designed for compatible residential, commercial, recreational vehicle, and off-grid energy storage systems. Each battery provides 5,120Wh nominal energy, with a 3U rack-mount form factor for organized battery-bank installations. Built-in Wi-Fi and Bluetooth monitoring, an LCD and LED interface, and RS485, RS232, and CAN communication ports support system visibility and compatible inverter communication when properly configured. An integrated 150W subzero heater supports low-temperature charging management, while Rich Solar lists UL1973 and UL9540A certification for this model. Final system design, inverter compatibility, rack configuration, wiring, and installation should be confirmed by a qualified professional using current Rich Solar documentation.
The ALPHA 5 PRO combines 51.2V nominal voltage with 100Ah capacity for 5.12kWh of stored energy per battery. Its 3U rack-mount design is intended for structured battery-bank installations in compatible energy storage systems where service access, capacity expansion, and organized equipment placement matter.
Wireless monitoring allows operating information such as state of charge, voltage, current, temperature, and remaining capacity to be viewed through the compatible app. RS485 and CAN protocol options are listed for communication with supported inverter brands, including Rich Solar, Pylon, Growatt, Schneider, Luxpower, Victron Energy, Sol-Ark, GoodWe, Solis, Senergy, SMA, and Megarevo, with the correct protocol selection required during setup.
Rich Solar identifies an integrated 150W subzero heater for charging support in cold conditions. The product information states that charging is off below 32°F, internal heating starts below 41°F, and internal heating stops above 50°F, helping the battery manage low-temperature charging conditions within the documented operating requirements.
The ALPHA 5 PRO includes a smart battery management system, automatic cell balancing, a built-in circuit breaker, and front-panel status visibility. Rich Solar documents overcharge, over-discharge, overcurrent, temperature, and short-circuit protection functions, while the manual states that wiring and installation work should be performed by qualified personnel.
The ALPHA 5 PRO stores 5.12kWh per battery in a compact 3U rack-mount format designed for compatible 48V-class energy storage installations.
Wireless monitoring, front-panel status indicators, and communication ports support practical battery visibility and properly configured inverter integration.
