Efficient energy storage for modern projects

The BOS-G 70 PRO offers, with its high voltage of 716.8 volts and a wide operating voltage range of 616 to 817.6 volts, an excellent basis for integration into existing energy systems. The lithium iron phosphate technology used ensures high safety, low self-discharge and a long service life.

Modular and customisable

The system architecture allows flexible expansion to up to 16 parallel battery racks and AC-parallel operation of up to 10 Deye inverters. This means the system can be precisely adapted to increasing requirements and remains expandable in the long term.

Safe energy management

The integrated BMS permanently monitors cell voltages, temperatures and charge states. It actively protects against critical operating conditions and, by means of automatic cell balancing, optimises the service life of the battery units.

Who is the Deye BOS-G 70 PRO suitable for?

The high-voltage storage set is ideal for:

• Commercial operations with high energy consumption or emergency power requirements
• Large photovoltaic systems focused on optimising self-consumption
• Private households with above-average energy needs
• Project developers requiring a modular, certified high-voltage system
