Key Benefits
- 3,840Wh nominal energy
- 300A maximum charge and discharge current
- Bluetooth monitoring and internal heating
- IP65 enclosure
- Supports up to four batteries in parallel
What’s Included
- One Rich Solar ALPHA 3 12V 300Ah LiFePO4 Battery
- Integrated battery-management system (BMS)
- Manufacturer documentation
Best Uses
- Large RV and motorhome systems
- Marine house banks
- High-output 12V inverter systems
- Cabin and off-grid power
- Emergency backup storage

Compatibility and Installation
Use a LiFePO4-compatible charger or inverter/charger set for the battery’s nominal voltage and charging profile. Size cables, terminals, disconnects, and overcurrent protection for the expected current. Confirm communication compatibility before relying on closed-loop BMS control. Do not wire batteries in series unless Rich Solar specifically approves that configuration. Installation must follow the manufacturer manual and applicable electrical codes.
Frequently Asked Questions
How much usable energy does it provide?
The nominal rating is 3,840Wh. Real usable AC energy is lower after inverter conversion and depends on operating conditions.
Does it have low-temperature support?
Internal heating supports cold-weather use. Follow the published temperature limits and allow the heater/BMS to manage charging protection.
Can I add more battery capacity later?
Rich Solar lists support for up to four matching batteries in parallel. Follow the manual for balancing, fusing, cabling, and commissioning.
Will it work with my inverter?
It can work with an appropriately sized 12V-class inverter/charger that supports LiFePO4 charging. For communication-based systems, verify the exact protocol and firmware first.
What warranty applies?
Rich Solar lists a 5-year warranty for this model.
