Description

Deye BOS-G 40 Pro - 40.96kWh High-Voltage Battery Storage Set is the uncompromising energy solution for large residential buildings, multi-family homes, and commercial applications. If you produce large amounts of solar power, you need a reliable partner to put this energy to use without losses. Thanks to the innovative high-voltage architecture, this system operates with extremely low line losses. Your self-generated electricity flows highly efficiently from the roof directly into the large battery storage and is available to you exactly when you need it.

Your Key Benefits at a Glance

Maximum safety: The long-lasting lithium iron phosphate cells (LiFePO4) are the safest choice on the market. They are absolutely thermally stable and are completely free of the questionable heavy metal cobalt.
Powerful capacity: With a massive 40.96 kWh storage capacity, this set offers enormous reserves. This lets you effortlessly supply your own power to energy-intensive loads at night or on cloudy days.
High-performance high-voltage technology: The clever series connection of the modules increases the system voltage. This significantly minimizes energy losses and enables very fast charging and discharging for maximum efficiency.
Active system protection: The integrated smart battery management system (BMS) monitors every cell around the clock and reliably protects the entire system from overcharging, deep discharge, or short circuits.

Intelligent Energy Management for Your Everyday Life

A modern large-scale battery storage system is the intelligent heart of your energy supply. When your solar system produces an abundance of electricity during the day, the Deye high-voltage system captures this valuable energy. As soon as the sun sets, operations start, or demand in the building increases, you simply draw on your free electricity. This drastically reduces your monthly energy costs and gives you long-term planning security. In addition, the system is ideally prepared for safe backup power operation: if the public grid fails, the battery storage, combined with the inverter, continues to supply your most important loads completely seamlessly within a fraction of a second.
