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

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%.
