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
wire to make sure there is no loose or
pulling off.

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 2.4kW from your 3kW system, then
the Export Limit Rate of 3kW inverter is
80.0%.
