The Rich Solar ALPHA 4 is a 24V 100Ah lithium iron phosphate battery designed for electrical-power storage in compatible motorhome, recreational vehicle, camping, trailer, van, boat, and off-grid power systems. With 25.6V nominal voltage and 2,560Wh nominal energy, it provides defined battery storage capacity for properly designed mobile or recreational power systems. Built-in Bluetooth communication supports battery-status viewing through the RICH SOLAR app, while the integrated battery management system provides documented overcharge, over-discharge, over-current, short-circuit, temperature-protection, and balancing functions. Internal heating supports low-temperature charging conditions when charging current is present, with the official specification sheet and manual listing 200W heating power. The battery must be installed and connected according to manufacturer instructions, with electrical power-supply connection completed by a qualified electrician.
The ALPHA 4 combines a 100Ah nominal capacity with a 25.6V battery architecture for 2,560Wh of nominal stored energy. Rich Solar identifies the battery for motorhomes, recreational vehicles, and camping applications where a properly sized 24V battery system is required.
Built-in Bluetooth communication allows users to pair the battery with the RICH SOLAR app for operating visibility. The official app guide identifies Real-time, History, Control, and Parameters screens for reviewing information including charge level, remaining capacity, voltage, current, temperature readings, cycle count, and protection counts.
The integrated heating system is managed by the battery management system and activates only when low-temperature charging protection is present and charging current is available. Rich Solar states that the battery does not use its own internal power to activate the heater, and the heating function turns off after the required temperature threshold is reached.
The ALPHA 4 includes an integrated battery management system with documented overcharge, over-discharge, over-current, short-circuit, temperature-protection, and balancing functions. The manual permits up to four matching ALPHA 4 batteries in parallel when configured according to its instructions, and states that electrical power-supply connections must be completed by a qualified electrician.
Designed for compatible 24V mobile and recreational power systems, the ALPHA 4 combines lithium iron phosphate storage with app-based operating visibility and low-temperature charging support.
Its 2,560Wh nominal energy rating, integrated battery management system, IP65 protection class, and documented parallel capability help support careful system planning and long-term ownership.
