The “Monster” of energy storage — the SMK 18kWh Lithium Battery delivers massive, uninterrupted power for hospitals, factories, luxury estates, and other high-demand facilities. Engineered for industrial-grade performance, it provides a long-lasting and reliable solution for even the most energy-intensive applications.
The SMK 18kWh Lithium Battery is our largest and most powerful energy storage solution, built specifically for industrial environments and large-scale residential systems.
Designed to complement 11kW hybrid inverters and multi-unit parallel configurations, it provides the energy density required to run heavy equipment and full-property installations with confidence.
Built with industrial-grade LiFePO4 cells, this battery maintains thermal stability, high discharge efficiency, and exceptional durability under continuous heavy load.
Its advanced Smart Battery Management System (BMS) ensures precise cell balancing, surge handling, and optimized charge cycles — extending lifespan and maintaining peak performance.
This is the ultimate generator replacement solution for high-demand users.
Capable of delivering 24+ hours of continuous power (load dependent) for:
Backup duration depends on total system load and configuration.
At SMK Solar Nigeria, we provide energy solutions designed specifically for Nigerian households and businesses. Since 2016, we’ve helped thousands transition from unreliable grid power and maintenance-heavy lead-acid systems to smart lithium storage.
Rated for 4,000+ cycles at 80% Depth of Discharge (DoD), this battery is designed to last over 10 years under normal operating conditions — far outperforming conventional lead-acid alternatives.
Delivers more usable energy than four 200Ah lead-acid batteries combined, while occupying significantly less space and reducing overall system weight. Perfect for homes where space efficiency matters.
The built-in LCD screen displays: Real-time voltage Remaining capacity Battery health status Giving you full visibility and control over your energy storage.
The SMK Lithium Battery is more than just a battery — it’s a long-term energy investment. Compact, powerful, and built for Nigerian solar systems.
