Description

Deye BOS-G 30 Pro - 30.72kWh High-Voltage Battery Storage Set is the ultimate solution for anyone who wants to make the most of their self-generated solar power and sustainably lower their electricity bills. Specially designed for large single-family homes, multi-family buildings, or commercial operations, this high-voltage system delivers impressive performance. Thanks to its advanced technology, you benefit from extremely low energy losses, ensuring your valuable solar power is used with the highest efficiency exactly where you need it most.

Your Key Benefits at a Glance

Maximum safety: The long-lasting lithium iron phosphate (LiFePO4) cells are considered the safest battery technology on the market. They are extremely temperature-resistant and are completely free of the environmentally harmful heavy metal cobalt.
Enormous storage capacity: With a generous 30.72 kWh, this set offers plenty of room to safely store even very large amounts of solar energy for the night or cloudy days.
Efficient high-voltage technology: The clever series connection of the battery modules enables high system voltages. This reduces line losses to an absolute minimum and allows for particularly fast charging and discharging processes.
Active system protection: The integrated smart battery management system (BMS) monitors every cell around the clock and reliably protects your entire system from overcharging, deep discharge, and short circuits.

Smart Energy Management for Everyday Life

A future-proof battery storage system is now the clever centerpiece of your residential or commercial energy supply. When your solar system produces more power than you're currently using on sunny days, the Deye high-voltage system captures this surplus and stores it safely. As soon as the sun sets or demand in the building increases, you simply draw on your free solar power again. This noticeably reduces your monthly energy expenses and gives you a reassuring sense of security. In addition, the system is excellently equipped for reliable backup power operation: if the public grid fails, the storage system can seamlessly continue supplying important devices in your household with power within a fraction of a second.
