Deye BOS-G PRO Cable Set 5 metres

The Deye BOS-G Cable Set is the essential connection kit for the installation and commissioning of the Deye BOS-G high-voltage battery series. This set establishes a secure connection between the battery tower (cluster) and the hybrid inverter. It includes all the necessary cables for power transmission (DC) as well as the intelligent communication between the Battery Management System (BMS) and the inverter.

With a standard length of 5.0 metres per cable, this set offers maximum flexibility in choosing the location of the battery storage and inverter, even if they cannot be mounted directly next to one another. All components are designed for the high voltages and currents of high-voltage systems and guarantee low-loss energy transmission.

Key features at a glance

• Complete set: Contains all cables required for connecting a BOS-G battery cluster to the inverter.
• Long reach: The generous cable length of 5.0 metres enables flexible installation in utility rooms or garages.
• Optimised cable cross-sections: The DC power cables are dimensioned for the high loads of high-voltage systems in order to minimise heating and voltage drops.
• Secure connectors: Pre-assembled connectors ensure error-free polarity and quick plug-and-play installation.
• Interference-free communication: The shielded communication cable ensures precise data exchange between the BMS and inverter.
• Industrial quality: Robust insulation and high-quality materials for lasting reliability in stationary storage applications.

Components of the set

• 1x EPCable 5.0 (Positive Power Cable)
  • The red DC power cable for connecting the positive terminal between the Battery Control Box (BMS) and the inverter.
• 1x ENCable 5.0 (Negative Power Cable)
  • The black DC power cable for connecting the negative terminal between the storage cluster and the inverter.
• 1x ECOM Cable 5.0 (Communication Cable)
  • The dedicated data cable (RJ45-based) for CAN/RS485 communication, allowing the inverter to read the battery data in real time.

Installation & safety instructions

• Strain relief
  • When routing the 5-metre cables, make sure they are laid without kinks and fixed to solid structures to avoid mechanical tension on the connections.
• Secure plug connection
  • Ensure that the power connectors click audibly into place. A loose connection can lead to arcing and overheating under high loads.
• Connection sequence
  • Always connect the communication cable (ECOM) first and check the correct assignment before energising the DC power cables.

FAQs about the Deye BOS-G Cable Set

Can I shorten the cables myself?

Not recommended. The cables are factory-fitted with special high-current crimp contacts. Manual shortening without professional tools can increase the transition resistance and compromise the safety of the system.

Is this set also suitable for the BOS-A series?

Only to a limited extent. Check the plug compatibility on the control box beforehand. While the communication protocol is often identical, the physical DC connections can differ between different model series.

Why is the ECOM cable so important?
