P 6.2-9 Control & Set includes ： Alarm Cancel, Fault Resetting, Parallel Master/Slave settings, 3phase 380V output Master/Slave B/Slave C settings.
  • Page 23 6.2.1 Parallel Master-Slave Setting In the Parallel Application, only one “Master” is needed. The rest of the inverters are “Slave”. The Master does not need to be set, only the Slave. Note! Two inverters cannot be set as Master. All Slave inverters are required to be set. If two inverters are set as Master, it could cause permanent damage to the inverters! Move the cursor to Parallel Set “Master”, hold the＂∧＂choose “Master and Slave”.

  • Page 24: Fault Code

    6.3 Fault Code 6.3.1 Short-C Meaning: Short-circuit Reason: Boost switch tube or output IGBT drive circuit short circuit protection Solution: 1.Remove the short circuit line's source. 2.The load has a large capacitor, remove. 3.The output error of active devices, remove; 6.3.2 Over-C Meaning: Over-current Reason: When the load current is more than 1.5 times,the time longer than 1 second Solution: 1.
  • Page 25 6.3.7 Bat Hi Meaning: Battery over voltage Reason: Battery voltage is too high Solution: 1. When there is a sudden disconnect the battery connection action, the action is very dangerous, check the battery wiring is reliable. 2. The battery capacity is too small, the charging current relative to the battery is too high, increase the battery capacity.
  • Page 26 6.3.13 CAN O-T Meaning: CAN communication over time Reason: CAN slave detect the communication interrupt timeout Solution: 1. CAN communication wire is not reliable,exclusion it; 2. CAN network must have an 120Ω anti reflection resistance, every device has an 120Ω resistance, but the entire network can only have one device short connect to this resistance,proposed short connect with the farest one from master.
