Description

Deye BOS-G 25 Pro - 25.6kWh High-Voltage Battery Storage Set is the professional solution for anyone who wants to make optimal use of their solar power and become permanently independent of fluctuating electricity prices. This powerful high-voltage system is specifically designed for demanding single-family homes and smaller commercial operations. Thanks to the high system voltage, you benefit from extremely low line losses, so your valuable solar power arrives exactly where you need it.

Your Key Benefits at a Glance

Maximum safety: The lithium iron phosphate (LiFePO4) cells used are absolutely safe, extremely temperature-resistant, and completely free of the concerning heavy metal cobalt.
High performance: The series connection of the high-voltage modules drastically reduces energy losses. This enables particularly fast charging and discharging processes.
Intelligent protection: The integrated battery management system (BMS) continuously monitors each individual cell and actively protects your entire system from overcharging, deep discharge, or short circuits.
Modular expandability: The system grows with your needs and can easily be adapted to increasing power demand by adding additional modules.

Comprehensive Energy Management for Everyday Life

A modern battery storage system today needs to do more than just store energy. The Deye high-voltage system forms the intelligent heart of your home energy management. When your solar system produces more power during the day than is being used in the house, the system safely stores this surplus. In the evening or at night, you simply draw on this free electricity again. This noticeably lowers your monthly electricity costs and gives you a reassuring sense of security. The set is also optimally prepared for backup power operation: in the event of a public grid outage, the system can continue supplying critical devices in your household with power within fractions of a second.
