The LNEPower Low Voltage Battery System 2.5L is a reliable, scalable, and smart energy storage solution, engineered for residential and small commercial energy storage integrators, solar EPC contractors, and renewable energy solution providers. Built with cobalt-free lithium iron phosphate (LiFePO4) cell chemistry, this low-voltage ESS delivers exceptional thermal stability, long cycle life, and reliable performance even in harsh operating conditions. With a single module capacity of 2.56kWh and flexible expandability from 2.56kWh up to 25.6kWh, it enables clients to tailor energy storage solutions to diverse customer needs, from single-home backup power to small commercial peak shaving systems.
This modular stackable energy storage system features a tool-free stacked design, allowing seamless capacity expansion from 2.56kWh to 25.6kWh by adding standardized battery modules. For installation partners, this reduces inventory pressure – you can stock universal modules and configure solutions for any customer demand – while the simplified installation process cuts on-site labor time and costs by up to 50% compared to traditional fixed-capacity battery systems.
Built with cobalt-free LFP battery cells, this system delivers unmatched thermal and chemical stability, eliminating thermal runaway risks and ensuring maximum safety for residential and commercial installations. It offers a cycle life of over 6000 cycles at 90% depth of discharge (DoD), with a standard 10-year warranty, reducing replacement costs and long-term maintenance burdens for end clients, and enhancing your brand’s reputation for reliable renewable energy solutions.
This low temperature charging ESS supports reliable charging at temperatures as low as -10°C, making it suitable for installation in cold climate regions where traditional battery systems suffer performance degradation. With an IP65 protection rating, it is fully dust-tight and water-resistant, supporting both indoor and outdoor installation, and adapting to harsh environmental conditions with consistent performance.
The integrated intelligent BMS (Battery Management System) provides real-time monitoring, overcharge/over-discharge protection, and cell balancing, maximizing system safety and performance. It supports remote firmware upgrades, eliminating the need for on-site maintenance visits, reducing after-sales service costs for partners, and enabling seamless system optimization throughout its service life.
