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

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.

Under the permission given by your energy
provider, the ratio of your system output
power divided by the rated power of the
inverter is called Export Limit Rate. For
instance, if the energy provider only
accepts 4kW from your 5KW system, then
the Export Limit Rate of 5kW inverter is
80.0%.
