Control Box (Control Unit) for Deye BOS-G-PDU-2 Battery, High Voltage

This is the box that commands a Deye battery cabinet from the BOS-G series. It contains no cells and stores no energy, it connects the battery modules to each other and makes the link to the inverter. The main BMS, the contactors, the protections and the display on which the system status is read, without the need for a computer or an app, are also here.

One unit coordinates between 3 and 12 BOS-G-Pack5.1 modules of 5,12 kWh each, that is banks between 15,36 and 61,44 kWh, suitable for guesthouses, commercial spaces, farms or workshops. The nominal charge and discharge current is 100 A, with a maximum allowed of 120 A, so the system can deliver energy quickly when consumption rises abruptly. The unit weighs about 19 kg, is mounted in a standard 19 inch rack and works over a wide temperature range, from -20 to 65 degrees C. The package already includes the termination resistor, the communication and power cables of various lengths, the earthing conductor and the interconnection cables between cabinets, for the case where the system is later expanded.

Model BOS-G-PDU-2, working range 200-1000 Vdc, nominal charge/discharge current 100 A, maximum 120 A, auxiliary supply 12 V +/- 2% at 4,15 A. Managed modules: 3-12 x BOS-G-Pack5.1 (15,36-61,44 kWh) connected in series. CAN and RS485 communication for synchronisation with compatible Deye inverters, integrated display for status, alarms and main parameters. Dimensions 440 x 570 x 150 mm (19 inch rack), mass 19 kg, protection degree IP20, operating temperature -20...65 degrees C.

Who it suits

Suitable for a commercial installation or a farm that is building or expanding a high voltage Deye BOS-G bank between 15 and 61 kWh, coupled to Deye HV hybrid inverters.

Terms explained

• Series connection: The modules are chained one after the other and their voltages add up; this way less current flows through the cables for the same power.
• 12 V auxiliary supply: A small, separate source that keeps the control electronics powered even when the battery bank is disconnected.
• 19 inch rack: The technical cabinet standard in which the equipment is mounted, the same one used in server rooms; it provides fixing and predictable dimensions.

Technical details

Specifications confirmed from the manufacturer's datasheet

Deye BOS-G-PDU-2 is the control box for the high voltage battery clusters of the BOS-G series. Its role is to connect the 5,12 kWh BOS-G-Pack5.1 modules in series and to make the link with the inverter, concentrating the master BMS, the contactors, the protections and the status display.

The operating voltage range is 200 - 1000 Vdc, depending on the number of modules connected in series: between 3 and 12 modules, that is between 15,36 and 61,44 kWh. The nominal charge and discharge current is 100 A, and the maximum allowed is 120 A. The auxiliary supply of the electronics is at 12 V with a tolerance of 2%, at a current of 4,15 A.

Communication is done through CAN and RS485, for synchronisation with compatible Deye inverters, and the integrated display shows the system status, the alarms and the main parameters. The unit is mounted in a 19 inch rack, having dimensions of 440 x 570 x 150 mm and a mass of about 19 kg, with protection degree IP20.

The operating temperature range is wide, -20...65 degrees C. Standard delivery includes the termination resistor, the communication and power cables of various lengths, the earthing conductor and the interconnection cables between cabinets, for expanding the system.
