Description

Deye BOS-G 85 Pro - 87.04kWh High-Voltage Battery Storage Set is the absolute flagship of this series and the maximum configuration for your commercial power supply. Designed for industrial facilities, large solar parks, and energy-intensive agriculture, this powerhouse handles any challenge. The advanced high-voltage technology ensures that energy losses are kept to an absolute minimum. Your valuable solar power is directed with maximum efficiency exactly where it lowers your operating costs most effectively.

Your Key Benefits at a Glance

Maximum safety: The long-lasting lithium iron phosphate cells (LiFePO4) are the safest choice for large industrial projects. They are thermally absolutely stable and completely free of the concerning heavy metal cobalt.
The absolute maximum: With a massive 87.04 kWh storage capacity, this set offers the largest reserves in the series. Effortlessly power even the most energy-intensive facilities at night or cap enormous load peaks during the day.
Powerful high-voltage technology: The clever series connection of the modules increases the system voltage to a maximum. This significantly minimizes energy losses and enables extremely fast charging and discharging for the highest efficiency.
Active system protection: The integrated smart battery management system (BMS) monitors every cell around the clock and reliably protects this massive system from overcharging, deep discharge, or short circuits.

Intelligent Energy Management for Large-Scale Commercial Use

This masterpiece of storage capacity is the heart of your self-sufficient power supply. When your gigantic solar system produces electricity in abundance during the day, the Deye high-voltage system safely captures this valuable energy. When the shift starts or heavy equipment ramps up, you draw your free electricity instantly and at high power. This radically reduces your monthly energy costs and protects your business from fluctuating electricity prices. In addition, the system is ideally prepared for reliable backup power operation: if the public grid fails, the storage system, combined with the inverter, seamlessly continues to supply your essential systems within fractions of a second, preventing costly production downtime.
