Interface Changes:

The shape and position of the communication port on the PRO battery pack differ from those on the original BOS-G system.

Bracket Compatibility:

The PRO system maintains the same structure as the original 3U-H RACK and 3U-L RACK brackets; existing brackets can still be used, saving on hardware investment.

Capacity Expansion Capability:

The BOS-G system supports up to 12 battery packs (60 kWh).

The BOS-G PRO system supports up to 16 battery packs (81.92 kWh).

→ More suitable for large-capacity commercial projects.

II. Common Customer Questions and Handling Recommendations

Question 1: The high-voltage system BMS of the original BOS-G is configured with 12 battery modules. Can BOS-G PRO battery packs be connected?

Answer: Yes, but the number must be limited to 12 modules or fewer; otherwise, the voltage will exceed limits and the BMS will not recognize them.

Question 2: What should be done if a customer uses a BOS-G high-voltage box with all BOS-G PRO battery packs?

Answer: Purchase an additional accessory kit: 10100602000085 BOS-GM5.1 BOS-GM5.1 BCable 2000 DEYE BOS-G After-Sales Accessory Kit (Single Carton)

Question 3: What should be done if a customer uses a BOS-G high-voltage box with both BOS-G PRO and BOS-G battery packs?

Answer: It is mandatory to require the customer to place the batteries in separate layers, for example: place BOS-PRO on the lower layer and BOS-G on the upper layer, and clearly label each. Mixed insertion is not allowed. Otherwise, it is recommended to use a separate bracket for batteries of the same model. Additionally, purchase the accessory kit: 10100602000085 BOS-GM5.1 BOS-GM5.1 BCable 2000 DEYE BOS-G After-Sales Accessory Kit (Single Carton)
