4,800Wh of Rack-Mounted Power for Residential and Commercial Systems
The ALPHA 5 is Rich Solar’s 48V 100Ah server rack battery — built with Grade A LiFePO₄ cells rated for 7,000+ cycles and a 10-year warranty, designed for parallel expansion in residential, commercial, and off-grid installations. Available by pre-order, produced to demand.
Built for Rack-Mounted Installations
The ALPHA 5 is a different kind of ALPHA battery — a 48V 100Ah server rack unit built for residential, commercial, and off-grid energy storage rather than mobile use. Grade A LiFePO₄ cells deliver 7,000+ charge cycles and low self-discharge, housed in a metal server rack enclosure designed for long-term, rack-mounted durability.
Multiple units can be connected in parallel to scale system capacity, with an included RS485 communication cable simplifying integration. Because each battery is produced to demand, it’s available by pre-order with delivery of up to 60 days.

Where It Fits
Common Questions
Why is this pre-order only?
The ALPHA 5 is produced based on demand rather than kept in standing inventory, so orders ship within approximately 60 days rather than immediately.
Does it have Bluetooth or self-heating like the portable ALPHA batteries?
No — the ALPHA 5 is built for stationary, rack-mounted installations rather than mobile use, so it doesn’t include the Bluetooth app monitoring or internal self-heating found on the ALPHA 1 and ALPHA 2 lineups.
Can multiple units be connected together?
Yes — it supports parallel expansion to scale system capacity, with an RS485 communication cable included to simplify integration between units.
Is a rack included?
The battery ships with its own metal server rack enclosure. Bundles combining multiple batteries with a shared rack are also available as separate purchase options.
What’s the warranty?
The ALPHA 5 is backed by a 10-year warranty.
