Confirm the DC Switch is turn on.

Guidance for installer

Step1: Measuring the voltage on the PV side with a multimeter, ensure the red probe is connected to the positive terminal and the black probe to the negative terminal. The correct measurement should be a positive number within the MPPT range. If a negative number appears, it indicates that the PV wires are reversed. If the voltage is too low, wait for sufficient solar energy to start the device.

Measure the PV terminal voltage

Step2: After measuring the voltage on the PV side, check the voltage of the PV on the screen of the inverter to see if it matches the measured voltage.

Setting Path: System Status➡️ PV1/PV2

Step3：Ensure that the PV terminals are sourced from the SolaX accessory kit.

Step4: 

Use a multimeter to measure the voltage at the inverter's AC port. In a three-phase system, measure the line voltage.

Step5:Upgrade the firmware version to the latest.

Step6: Only connect the PV, disconnect the AC switch, and check if the inverter screen lights up.

Tips: For X3-hybrid G4，check the COM connector to ensure that PIN3&6 is not short-circuited. Then check the Shutdown connector to ensure that PIN4&6 is not short-circuited.
