Marstek 5Kwh Lithium Battery

The Marstek Modular Lithium Battery Storage System is a powerful, scalable, and ultra-safe energy storage solution tailored for residential and commercial solar applications. Built with high-grade LiFePO₄ (Lithium Iron Phosphate) battery cells and engineered for high efficiency, this system allows you to store solar energy during the day and use it anytime—day or night, during blackouts, or peak tariff hours.
Whether you are powering a home, a hotel, a farm, or a remote industrial site, Marstek’s ESS offers reliable backup, flexible installation, and impressive longevity—all while helping you reduce electricity bills and dependence on the grid.
Modular & Scalable Design:
This battery storage system offers flexibility through its modular structure. You can start small and scale up as your energy needs grow. Each module delivers 5.12kWh of storage capacity, and you can combine between 2 to 6 modules to achieve total system capacities ranging from 10.2kWh to 30.7kWh. This adaptability makes it suitable for both light residential users and heavy commercial consumers.
Safe & Long-Lasting:
At the heart of the system are Class A, large monomer laminated LiFePO₄ cells, which are known for their superior thermal and chemical stability. These batteries support over 6000+ charge-discharge cycles at 90% Depth of Discharge (DoD)—meaning they can last over 10 years with daily use.
Each module is equipped with an intelligent Battery Management System (BMS) that provides real-time protection against over-voltage, under-voltage, over-current, short-circuit, over-temperature, and under-temperature. This ensures not only user safety but also system reliability in all environmental conditions.
Smart Integration & Wide Compatibility:
These batteries are designed to integrate easily with most hybrid inverters on the market. Supported communication protocols like RS485 and CAN allow for seamless integration with third-party inverters and energy monitoring systems.
This wide compatibility makes installation easier and avoids the need for expensive replacements or changes to your existing solar setup.
Rugged & Weather-Proof:
Built to handle tough conditions, the Marstek lithium battery storage system features an IP65-rated waterproof and dustproof enclosure, making it suitable for both indoor and outdoor installations. It operates effectively in temperatures ranging from -20°C to 60°C, withstanding the heat of the tropics or the cold of high-altitude regions.
Each module can be wall-mounted or floor-standing, giving installers and users flexibility to optimize space and aesthetics.
