48V 200Ah Wall-Mounted Powerwall Battery

48V 200Ah Wall-Mounted Powerwall Battery

48V 200Ah Wall-Mounted Powerwall Battery is an all-in-one solution for home energy storage, which integrates the battery, UPS, and battery cabinet into a modular system for easier and faster installation.

Ultra-high power is widely used in solar power generation, wind energy systems, UPS systems (uninterruptible power supply), telecommunication systems, railroad systems, switch and control systems, emergency lighting systems, broadcasting radio and broadcasting stations, and commercial home solar energy storage systems.

The system can connect to the customer’s home internet and store energy through the battery to meet the customer’s needs.

The Battery Management System (BMS) features protection against over-discharge, over-charge, over-current, high and low temperatures.

The BMS system can automatically manage the charging and discharging status and balance the current and voltage of each battery.

I am operating a temperature range of 32F to 122F (0C to 50C) with excellent discharge performance and cycle life.

Li-ion battery BMS is a very important battery pack safety protection accessory, that adopts a high-quality Keheng New Energy self-developed BMS circuit protection board, realizing over-charging, over-discharging detection, high temperature, and short circuit detection.
