PRAG 5kWh Lithium-ion Battery: The Future of Efficiency

The PRAG 5kWh/48V LiFePO4 Lithium Battery is an advanced energy storage solution that defines the next generation of solar power in Nigeria. Engineered for longevity and extreme reliability, this battery is the "gold standard" for 5kVA residential and small commercial systems.

At Kara Nigeria, the PRAG 5kWh Lithium Battery is currently priced at ₦1,884,840.00.

Importance of Solar Energy in Nigeria

With the removal of fuel subsidies and increasing grid instability, solar energy has transitioned from an alternative to a primary power source. For Nigerian homeowners, this means escaping the noise and pollution of generators while securing a stable, long-term energy cost. Lithium technology ensures that every bit of sunlight you capture is stored with maximum efficiency.

Advantages of Lithium Batteries Over Traditional Batteries

1. Incredible Lifespan: Offers 6,000+ cycles at 80% Depth of Discharge (DoD). This means the battery will last 10–15 years, whereas tubular batteries often fail after just 3–5 years.
2. Superior Efficiency: Boasts over 98% efficiency, allowing for faster charging and near-total power discharge without damaging the cells.
3. Lightweight & Compact: Weighing just 45kg, it is much easier to install and wall-mount than a heavy bank of lead-acid batteries.
4. Zero Maintenance: No water topping, no acid leaks, and no terminal corrosion.

Key Features of the PRAG 5kWh Battery

1. Grade A LiFePO4 Chemistry: The safest lithium tech available, designed to be non-toxic and thermally stable in high-heat environments.
2. Intelligent BMS: The Battery Management System protects against overcharging, short circuits, and overheating, ensuring the safety of your home.
3. Scalable Design: You can connect up to 15 units in parallel, allowing your system to grow as your energy needs increase.
4. Smart Monitoring: Compatible with mainstream hybrid inverters with CAN, RS485, and RS232 communication ports.

Top Lithium Battery Brands in Nigeria

PRAG is a trusted local powerhouse, but you can also explore these top brands at Kara Nigeria:

1. SMK Solar: Highly popular for its robust 5.12kWh modules and LCD screens.
2. Sako Solar: Offers exceptional value for 48V/51.2V LiFePO4 storage.
3. Felicity Solar: Known for larger wall-mounted units (10kWh - 15kWh).

Installation and Maintenance Tips

1. Inverter Sync: Always use the communication ports to link the battery to your inverter. This allows for active cell balancing and optimized charging.
2. Cool Environment: While lithium handles heat well, installing the unit in a cool, ventilated indoor area will prolong the life of its sensitive electronics.
3. Cabling: Use high-quality DC cables to ensure there is no energy loss or heating at the connection points.

Cost Analysis: Why Invest in Lithium?

While the upfront price is higher than tubular batteries, the Total Cost of Ownership (TCO) is significantly lower. Over a 12-year period, you would likely replace a tubular battery bank three times, eventually spending more than the cost of a single PRAG Lithium unit that is still performing at peak capacity.

Conclusion and Recommendations

For a standard 5kVA system, the PRAG 5kWh Lithium Battery is a one-time decade investment. It provides enough capacity to run lights, fans, and refrigerators comfortably through the night with zero maintenance.
