The Rich Solar ALPHA 5 is a 48V 100Ah lithium iron phosphate server rack battery designed for compatible residential, commercial, and off-grid energy storage systems. Each battery provides 4,800Wh nominal energy in a rack-mount enclosure with an LCD display, direct current circuit breaker, and RS485, RS232, and CAN communication ports. Its integrated battery management system supports documented charge, discharge, overcurrent, short-circuit, and temperature protection functions for properly configured systems. The official Rich Solar specification sheet lists a 100A maximum charge current, 100A maximum discharge current, and an IP21 protection class for this battery. Final inverter compatibility, battery-bank sizing, communication settings, rack selection, wiring, and installation should be confirmed by qualified professionals using current Rich Solar documentation.
The ALPHA 5 combines 48V nominal voltage with 100Ah rated capacity for 4.8kWh of stored energy per battery. Its server rack format is suited to organized battery-bank layouts where compatible equipment, clean installation planning, and service access are important.
Rich Solar specifies an LCD display along with RS485, RS232, and CAN communication capability. These features support local battery visibility and communication with compatible inverter or system equipment when the correct connections and settings are used.
The integrated battery management system is documented with protection functions for overcharge, over-discharge, overcurrent, short circuit, and temperature conditions. A built-in direct current circuit breaker and front-panel start/output switch provide local battery control features; system isolation and servicing procedures should follow applicable installation requirements.
Rich Solar lists the ALPHA 5 as a pre-order product, with the official product page stating that delivery may take up to 60 days because batteries are produced based on demand. This makes purchase timing, compatible equipment confirmation, and installation planning especially important before ordering.

The ALPHA 5 provides 4.8kWh of nominal lithium iron phosphate storage in a rack-mount format built for compatible 48V battery system layouts.
An LCD display, circuit breaker, and multiple communication ports support practical system monitoring and professionally configured battery integration.
