Wall-Mounted Energy Storage Battery – 48V 4.5kWh LiFePO₄
Wall mount series adopts high-quality lithium iron phosphate batteries, equipped with intelligent BMS battery management system, long cycle life, high safety performance, beautiful appearance, free combination and convenient installation. LCD display, visualization of battery operating data. Compatible with most solar inverters, providing efficient energy for photovoltaic off-grid households, commercial and other electrical equipment
Compact Energy Storage for Home and Off-Grid Power
This energy storage battery provides 4.5kWh of clean backup power. It mounts to the wall, saving space while delivering dependable performance. Use it with solar systems, off-grid cabins, or as a home backup.
The battery uses LiFePO₄ cells, which are safer and last longer than other types. You’ll get over 6,000 cycles at 80% depth of discharge. That’s more than 10 years of use in most systems.
A built-in Battery Management System (BMS) keeps your battery safe. It protects against overheating, short circuits, and overcharging. The unit runs quietly and produces no fumes—safe for indoor use.
