Note:
1.Before installing the PV terminal, please
double-check that the PV input voltage and
current do not exceed the MPPT limits.
2.When installing the PV terminal, pay
attention to the difference between the
positive and negative poles and the one-to-
one correspondence between the terminals
and the machine.
3.There is a "click" sound when the terminal
is connected,please gently pulling the PV

If the local grid company requires to limit the
output power from your inverter systems,we
introduce the concept of Export Limit Rate.The
ratio of your system output power divided by
the rated power of the inverter is called Export
Limited Rate.For example,if the local grid
companyonly accepts 4kW from your 5kW
system,then the Export Limit Rate of 5kW
inverter should 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 build-in DC isolator at the bottom of the inverter.
2.Switch on the PV Array and DC isolator next to your inverter, if you can not find this switch, 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.
