Please check the maximum input voltage of the inverter and output voltage of the solar cell
array. If the output voltage of the solar cell array exceeds the maximum input voltage of the
inverter, critical damage can occur in the inverter.
The output voltage must be set in consideration of temperature coefficient during wiring of the
solar cell module. If the output voltage of the solar cell array is set without consideration of
temperature coefficient, input over-voltage or low-voltage in the inverter can occur according to
an ambient temperature.

DC Connection
①
Open the cover by loosening 2 bolts in the bottom part.
②
Connect
PV (+) to the left part
of DC breaker
and
PV (-) to the right part of DC breaker
as
below
③
For DC wiring, pls. use 70SQ wire (pls. change the wire thickness depending on wiring length)
④
Wire and terminal lug should be designed according to 95℃ at least and tightening torque
should be 18 [N•m].
