Description

Deye BOS-G 45 Pro - 46.08kWh High-Voltage Battery Storage Set is the professional storage solution for demanding energy projects in large properties or commercial operations. This powerful high-voltage system was designed to safely absorb and efficiently deliver huge amounts of self-generated solar power. Thanks to the high system voltage, you benefit from significantly reduced energy losses, allowing your valuable solar power to be used optimally and drastically lowering your electricity costs.

Your Key Benefits at a Glance

Maximum safety: The lithium iron phosphate cells (LiFePO4) used offer maximum safety. They are extremely temperature-resistant and completely free of harmful cobalt.
Massive storage reserves: With an impressive 46.08 kWh capacity, this set provides ample room to easily bridge long nights or low-sun days using your own free electricity.
Efficient high-voltage technology: Thanks to the intelligent series connection of the battery modules, line losses are reduced to an absolute minimum. This ensures fast charging times and excellent energy yield.
Continuous system protection: The smart battery management system (BMS) continuously monitors every single cell and reliably protects your system from overcharging, deep discharge, or harmful short circuits.

Comprehensive Energy Management for Everyday Life

This battery storage system is the smart control center of your modern energy infrastructure. When your solar system produces more electricity than you consume during the day, the Deye system reliably captures this surplus. In the evening or during periods of high demand, this energy is then available to you free of charge. This protects you from unpredictable electricity price increases and strengthens your self-sufficiency. In addition, the set is perfectly equipped for smooth backup power operation: in the event of a public grid outage, the system kicks in and continues supplying important electrical loads within milliseconds.
