Description

Deye BOS-G 35 Pro - 35.84kWh High-Voltage Battery Storage Set is the ultimate energy solution for anyone who wants to use large amounts of self-generated solar power and massively reduce their electricity costs. Specially designed for large single-family homes, multi-family buildings, or small businesses, this high-voltage system offers impressive capacity reserves. Thanks to advanced high-voltage technology, you benefit from extremely low energy losses, allowing your valuable solar power to flow with maximum efficiency from the roof directly into the battery storage and your loads.

Your key advantages 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 completely free of the environmentally harmful heavy metal cobalt.
Massive storage capacity: With an impressive 35.84 kWh, this powerhouse offers more than enough capacity to safely store even very large amounts of solar energy for the night, cloudy days, or commercial operation.
Efficient high-voltage technology: The clever series connection of the battery modules enables high system voltages. This reduces thermal line losses to an absolute minimum and allows 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 battery system from overcharging, deep discharge, and short circuits.

Intelligent energy management for your everyday life

A future-proof battery storage system is today the smart heart of your building's or business's energy supply. When your photovoltaic system produces more electricity than you are currently using on sunny days, the Deye high-voltage system captures this valuable surplus and stores it safely. As soon as the sun sets or energy demand in the building increases, you simply draw on your free solar power again. This immediately reduces your monthly energy expenses and gives you a reassuring sense of financial security. In addition, the system is excellently equipped for backup power operation: if the public power grid fails, the battery storage, in combination with your inverter, can continue to supply critical loads with energy completely seamlessly within a fraction of a second.
