Description

Deye BOS-G Pro - 25.6 - 87.04kWh High-Voltage Battery Storage Set - Selectable is the uncompromising solution for anyone who wants to make optimal use of their own electricity and become independent of fluctuating power prices in the long term. Whether for a demanding single-family home, multi-family buildings, or small businesses – this forward-looking system grows with your requirements. Thanks to advanced high-voltage technology, you benefit from extremely low energy losses, meaning more of your valuable solar power arrives exactly where you need it.

Your Key Advantages at a Glance

Maximum safety: The lithium iron phosphate cells (LiFePO4) used are considered the safest technology on the market. They are completely free of problematic cobalt and extremely temperature-resistant.
Tailored capacity: Start with 25.6 kWh and effortlessly expand the system as needed up to a massive 87.04 kWh. This lets you adapt your battery storage to your lifestyle or business at any time.
Powerful high-voltage design: The series connection of the modules results in a high system voltage. This drastically reduces line losses and enables particularly fast charging and discharging times in combination with your inverter.
Smart battery management: The integrated battery management system (BMS) monitors every single cell in real time and actively protects the entire system from overcharging, deep discharging, or short circuits.

Intelligent Energy Management for Your Everyday Life

A modern battery storage system today needs to do more than just store energy. The Deye high-voltage system is designed to form the heart of your home energy management. In combination with a suitable hybrid inverter, the system controls the energy flow fully automatically. When your solar system produces more electricity during the day than you consume in the house, the surplus is stored in the battery storage with minimal losses. In the evening or at night, when the sun isn't shining, you simply draw on this free electricity again. This noticeably reduces your monthly electricity costs and significantly increases your security. The system is also optimally prepared for reliable backup power operation: in the event of an unforeseen grid outage, the system can continue supplying important devices in your household with power within a fraction of a second, so you're never left in the dark.
