Common Equipment Failures Solved

• Uneven load distribution of parallel generators: PID gain parameter setting error, CT current transformer wiring reversed
• Failed to synchronize with mains grid: Mains and generator phase sequence inconsistent, voltage/frequency threshold parameter wrong
• Onboard relay burnt when driving glow plug: Onboard contact capacity limited to 16A, install external Hongfa HAT700BI 70A heavy relay for current amplification
• Laptop cannot connect controller for debugging: Use SG72A RS485 conversion adapter, check A/B wiring reversal and baud rate matching
• No engine data displayed on CAN J1939 channel: CAN-H/CAN-L wiring reversed, engine ECU communication protocol mismatch
• Frequent reverse power protection shutdown during grid parallel operation: Grid parallel phase angle threshold set too sensitive, genset governor response lag
