OK
For regions where the local grid company
poses restrictions on the power output of your
solar system, we introduce the concept of
Export Limit Rate, which refers to the ratio of
the output power to the rated power of the
inverter. For example, if the local grid
company permits only 4kW from your 5kW
system, then the Export Limit Rate for the 5kW
inverter would be 80%.
Before turning the inverter on, please make sure the PV input voltage and current are within the MPPT limits.
Follow the steps below to turn the inverter on:
1.Switch on the built-in DC switch at the bottom of the inverter.
2.Switch on the PV Array and DC isolator next to your inverter. If the switch is not available, skip this step.
3.Switch on the Solar AC isolator if the inverter is more than 3 meters away from your switchboard.
4.Switch on the solar supply main switch in the switch board.
To shut down your system, follow the reverse order of the steps mentioned above.
If a backup box is connected, please
enable it when configuring the
inverter. For details, please refer to
Section 9.3.3 in the MID 11-30KTL3-
XH User Manual.
