The Solax Battery Lithium Ion 5.8 kWh 100 V-131 V with Integrated BMS is a high-performance energy storage solution designed to enhance residential and commercial solar power systems. Built with advanced lithium-ion (LiFePO₄) technology, this battery delivers dependable, safe, and efficient energy storage that’s well-suited for self-consumption, peak-shaving, and backup power applications. Its design incorporates a built-in Battery Management System (BMS), ensuring optimal cell balance, temperature regulation, and long-term reliability under varying conditions.

With a nominal energy capacity of 5.8 kWh and an operating voltage range of 100 V to 131 V, the Solax battery provides a versatile and robust storage foundation. Of this total, around 5.2 kWh is usable capacity, giving users substantial stored energy that can be relied upon to power household loads, critical circuits, or business equipment during grid outages or to maximise solar use during daylight hours.

Efficiency is a strong suit of this system: it achieves a faradic charge efficiency of 99 % and a round-trip efficiency of approximately 95 %, which significantly reduces energy losses during charging and discharging cycles. This means more of your solar energy is stored and available when you need it most. The unit’s depth of discharge (DOD) of up to 100 % allows you to utilise virtually the entire battery capacity without compromising performance, while still maintaining battery health.

Standard continuous power output is around 2.9 kW, with a peak output up to 3.5 kW, making this battery capable of supporting typical residential loads. The robust construction includes IP55 protection, allowing for both floor and wall installation in indoor or semi-protected outdoor environments. Mounting flexibility helps installers adapt the setup to different spaces without compromising safety or accessibility.

Safety and longevity are emphasised through a cycle life exceeding 6,000 cycles, and the battery is certified with industry standards such as CE, TUV (IEC62619), UL1973, ROHS, and REACH, ensuring compliance with international safety and quality requirements. Communication interfaces like CAN2.0 and RS485 facilitate seamless integration with compatible hybrid inverters for real-time monitoring and management.

Whether used as a single unit or combined with additional Solax batteries in series for greater storage capacity, the Solax 5.8 kWh lithium battery offers a flexible, efficient, and future-ready solution to bring energy independence and resilience to solar power systems
