Deye Commissioning – Battery Compatibility Deep Dive

In this practical technical session, Gareth Thomas walks through the exact setup steps required to correctly configure Deye inverters with the most common battery platforms supported by DPA.

The focus is simple: clear configuration, correct communication setup, and avoiding site delays caused by battery compatibility issues.

Batteries covered in this session include:

• Discover
• Pylontech
• PowerPlus

As more installers work across different battery brands, getting Deye setup right first time becomes increasingly important. Small configuration errors — especially around communication settings, battery mode selection, and cabling — can quickly lead to delays, fault finding, and unnecessary call-backs.

This session is designed to make that process clearer.

What we’ll cover
Closed-loop vs open-loop setup — understanding the difference, how each mode works, and when to use each one

Battery mode configuration — setting up the inverter correctly for different battery platforms

Pinouts and cabling — CAN / RS485 wiring requirements and the common mistakes that cause communication issues

PowerPlus integration — configuring self-managed batteries correctly

Troubleshooting — diagnosing BMS communication faults and resolving them efficiently

Firmware considerations — when updates are required for compatibility, and when they are not

Who should watch
Installers using or considering Deye hybrid inverters who want to reduce call-backs, avoid BMS communication errors, and confidently deploy multiple battery brands.
