Product Description

Product Description

High Efficiency Home Solar Power Generator System Wall-Mounted Energy Storage Battery for Photovoltaic Supply

Our Residential Solar Energy Storage System is designed to provide reliable, clean, and efficient power for modern homes. Whether you are looking for a backup power solution for grid outages or aiming for energy independence with an off-grid setup, this system delivers.
Constructed with high-grade Lithium Iron Phosphate (LiFePO4) chemistry, it offers superior thermal stability and safety compared to traditional lithium-ion batteries. The sleek, wall-mounted design saves floor space and blends seamlessly into garage or utility room environments. Integrated with a smart BMS, it communicates effectively with your inverter to optimize charging and discharging efficiency, ensuring your home stays powered when it matters most.

Key Features & Advantages

1.Premium LiFePO4 Chemistry: Unlike standard lithium-ion batteries, our system uses Lithium Iron Phosphate cells, renowned for their superior thermal stability and safety. This ensures the battery is non-combustible and can withstand high temperatures without risk.
2.Ultra-Long Cycle Life: Engineered for durability, the battery offers over 6,000 cycles at 80% Depth of Discharge (DOD). This translates to 10-15 years of daily usage, significantly lowering the long-term cost per kWh compared to lead-acid alternatives.

1.Intelligent BMS (Battery Management System): The built-in smart BMS acts as the brain of the battery. It provides real-time monitoring and comprehensive protection against over-charging, over-discharging, over-current, short circuits, and extreme temperatures, ensuring optimal performance and safety.

2.Space-Saving Wall-Mount Design: The compact and lightweight form factor allows for easy installation on walls in garages, utility rooms, or basements, saving valuable floor space. Its modern aesthetic blends seamlessly into residential environments.

1.Wide Compatibility: The system is designed to communicate seamlessly with most  hybrid inverters on the market (such as Growatt, GoodWe, Voltronic, SRNE, etc.) via RS485/CAN protocols, making integration into new or existing solar setups effortless.
2.Scalable Capacity: Available in 5kWh and 10kWh modules, the system can often be paralleled (depending on the specific model configuration), allowing you to expand your storage capacity as your energy needs grow.
