Common Equipment Failures Solved

  • LED no display after power on: Confirm battery voltage strictly DC12V, positive and negative wiring reversed check
  • Genset no auto startup when mains lost: Adjust mains abnormal detection delay threshold, recheck MV mains sampling wiring
  • Startup cycle 3 times and lock protection: Check fuel cut relay wiring, battery power insufficient, engine spark plug fault
  • ATS breaker cannot auto close: Reconfigure auxiliary output function as GCB close signal via panel parameter
  • Need remote mobile APP monitoring: MGC120 without RS485 port, upgrade to MGC320 with Modbus communication
  • Need three-phase generator matching: MGC120 only single-phase sampling, select MGC320 three-phase version
  • Need power consumption kWh statistics: MGC120 no CT input, install external single-phase power meter separately
