Description

Deye BOS-G 50 Pro - 51.20kWh High-Voltage Battery Storage Set is the ultimate large-scale storage solution for anyone who won't compromise on energy supply. This high-voltage system is the ideal choice for multi-family homes, agricultural operations, or commercial warehouses. Thanks to forward-thinking technology, you benefit from extremely low thermal losses, so gigantic amounts of your self-generated solar power are used with maximum efficiency exactly where you need the energy.

Your key benefits at a glance

Absolute safety: The robust lithium iron phosphate cells (LiFePO4) are considered the safest and most durable battery technology. They are thermally stable and completely free of the heavy metal cobalt.
Massive storage capacity: With a huge 51.20 kWh, this powerhouse offers more than enough room to safely store even very large amounts of energy for intensive commercial operation or nighttime use.
Efficient high-voltage technology: The well-engineered series connection of the high-voltage modules reduces current flow at the same power level. This drastically reduces line losses and enables particularly fast charging and discharging processes.
Active system protection: The integrated smart battery management system (BMS) monitors every cell in real time and reliably protects your entire investment from overcharging, deep discharge, and short circuits.

Intelligent energy management for large-scale applications

A battery storage system of this size is the highly intelligent heart of your commercial or private energy supply. When your large photovoltaic system produces massive power surpluses on sunny days, the Deye high-voltage system captures and safely stores it. As soon as the sun sets or machines start up in the building, you can immediately draw on your free solar power again. This noticeably reduces your monthly energy costs and makes you independent. In addition, the system is excellently equipped for reliable backup power operation: if the grid fails, the storage system, combined with the inverter, can seamlessly continue supplying critical loads with energy within fractions of a second.
