Description

Deye BOS-G 80 Pro - 81.92kWh High-Voltage Battery Storage Set delivers uncompromising performance for industrial applications. If you're generating solar power on a large scale across expansive roof or ground-mounted installations, you need an energy storage system built for the task. Thanks to forward-thinking high-voltage technology, you benefit from extremely low thermal losses. Massive amounts of your generated solar power are stored with maximum efficiency and delivered exactly where your systems urgently need it.

Your Key Advantages at a Glance

Absolute safety: The extremely robust lithium iron phosphate cells (LiFePO4) are considered the safest battery technology for large-scale storage systems. They are thermally stable and completely free of the hazardous heavy metal cobalt.
Massive storage capacity: With a staggering 81.92 kWh, this powerhouse offers more than enough capacity to safely store even very large amounts of energy for intensive commercial operations and draw on them precisely during peak loads.
Efficient high-voltage technology: The well-designed 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 cycles.
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 dangerous short circuits.

Intelligent Energy Management for Industry and Commerce

A battery storage system of this scale is the highly intelligent heart of your professional power supply. When your large photovoltaic system produces massive surplus power on sunny days, the Deye high-voltage system captures it directly and stores it safely. As soon as the sun sets or heavy machinery starts up, you can draw on your free solar power immediately. This smooths out costly load peaks and makes you significantly less dependent on the public power grid. In addition, the system is excellently equipped for reliable backup power operation: if the grid fails, the storage system, combined with the hybrid inverter, can continue supplying your critical systems with power within a fraction of a second.
