3.84kWh of heated, app-connected 12V storage
Put 300Ah of LiFePO4 capacity into one protected 12V battery enclosure.
The RICH SOLAR ALPHA 3 is a 12.8V 300Ah LiFePO4 battery with 3.84kWh of nominal energy, a 300A BMS, Bluetooth monitoring and 100W internal heat. It is designed for higher-capacity RV, cabin, marine-house-bank and off-grid 12V systems where one large battery can simplify interconnects.
At a glance
The numbers that define this system
Current product-specific documentation permits up to four identical ALPHA 3 batteries in parallel and does not support or document series use. Do not build a 24V or 48V bank by placing these batteries in series.
System fit
Plan around weight, high current and a single 12V architecture.
At 71.7 lb and up to 300A, this battery requires secure mounting, correctly torqued terminals, short properly sized cables and protection rated for the available fault current. Verify charger and inverter settings before connection.

Common questions
Before you build around this product
How much energy does it store?
The battery is 12.8V and 300Ah, equal to 3,840Wh or 3.84kWh nominal. Usable energy depends on settings and operating conditions.
Can I connect ALPHA 3 batteries in series?
Series use is not supported or documented. RICH SOLAR documents up to four matching batteries in parallel.
When does the heater operate?
The current data states that the 100W heater activates with charging current at or below 3°C / 37.4°F and stops when charging is removed or the battery reaches at least 10°C / 50°F.
Can it run a 3,000W inverter?
Potentially, but verify inverter surge, battery current, cable size, fuse/disconnect rating, terminal limits and desired runtime. Inverter wattage alone is not enough.
