• Environmentally friendly: Free from toxic substances, recyclable and with low energy consumption
• Compatibility: Perfectly matched to Deye inverters, including USB and remote upgrade

Efficient energy storage for modern applications

The BOS-G 30 PRO set is based on durable LiFePO4 technology and delivers a usable storage capacity of 27.65 kWh at a nominal voltage of 307.2 V. It is specially optimised for use with Deye inverters and can be easily updated via USB or remote access.

Flexibility & scalability

The modular design allows for easy expansion with additional battery units; up to 16 battery cabinets can be operated in parallel. This enables the system to scale from meeting the requirements of small commercial installations right through to industrial solutions.

Intelligent control & safety

The integrated BMS provides reliable protection against overcharging, deep discharge, overcurrent and temperature deviations. The system also ensures precise cell balancing and continuously monitors the state of charge for maximum safety and efficiency.

Applications of the Deye BOS-G 30 PRO

This high-voltage storage set is ideal for:

• Businesses looking to reduce their electricity costs and smooth out peaks in consumption
• PV system operators looking for flexible storage solutions with high scalability
• Homeowners with high energy requirements who wish to maximise their self-sufficiency
• Off-grid systems & backup solutions that require maximum reliability and self-sufficiency

FAQs on the Deye BOS-G 30 PRO high-voltage storage unit

How do I manually load individual BOS‑G modules?

You must not charge individual modules directly from the inverter. This can only be done within the grid-connected system. If you nevertheless wish to charge manually, approx. 57 V (LFP‑16S, 16 × 3.6 V) is permitted; the optimum is approximately 55 V, as this provides hardly any additional storage capacity. The modules have their own battery management systems (BMS), but they must not be subjected to higher voltages.

Do I need a fireproof room (T60) to operate the BOS‑G?

Yes, the EU manual explicitly states that the BOS-G Pro may only be used in fireproof rooms may be installed with T60-type fire-resistant windows and doors. From an insurance and safety perspective, it is essential that this requirement is adhered to.

What capacity and cycle life does the BOS‑G 30 PRO offer?

The system is available in several variants. The 30 PRO provides 30.72 kWh gross; usable space is approx. 27.65 kWh (90% DoD). The service life is ≥ 6,000 cycles at 25 °C and 0.5 C charge/discharge up to 70 % DoD. The warranty period is 10 years.

What protection functions does the BMS offer?

The integrated BMS protects against Overcharging, deep discharge, overcurrent, short circuits, as well as overvoltage, undervoltage and extreme temperatures. It also provides current and cell voltage balancing.

What is the system’s IP protection rating?
