Guidance for installer
Step1: Select another safety code to see if it can be saved successfully. If it can, this indicates a network delay; you can then switch back to the correct safety code.
Settings path: Setting→Advanced Setting→Safety
Step2: If the safety code cannot be saved, confirm that the DC Switch is flipped to ‘ON’. Then, use a multimeter to measure the PV voltage. Make sure within MPPT rang of the inverter.
If the system includes a battery, please refer to the user manual to ensure that the battery switch is properly turned on. The inverter screen should display <Normal>.
Step3: Turn the DC switch to 'OFF' to disconnect the PV, turn off the battery, and disconnect the grid power. Wait for the inverter screen to turn off for 15 seconds, then turn on all switches and wait for the inverter to return to <Normal> status before setting <Safety> again.
