Installation instruction

、
Please read the below notes carefully before installation.
A) Make sure the open voltage and operation voltage is in the range of 10.5-28V, and we recommend
the 18V rated voltage solar panel or 24V battery.
B) Make sure the inverter’s AC voltage and frequency is the same with power grid voltage and
frequency.
C) Installation inverter in the low humidity and well-ventilated place to avoid the inverter damp and
overheating, And clear the inflammable and explosive materials around.
D) Recommended to use 4AWG DC input cable that can handle more than 50A current.
E) DC input cable no more than 8M, because long DC cable will reduce the voltage from solar panel
to inverter, then make some loss.
F) There must be a circuit breaker between solar power generation and power grid(show like the
“ switch A” in figure 1). And there will be no load before the circuit breaker.
G) Before connect all the connections, you must disconnect the utility power. After make sure the all
connections are right then connect the utility power.
H) If you need to disconnect the mains switch when the solar power generation is in operation, you
must
disconnect the control switch first(show like the “switch A” in figure 1).
I) Avoid children touch or play the inverters, in order to prevent electric shock.
J) Non-professional do not disassemble the inverter, only qualified serviceman can repair it.

Connection DC terminal
Connect the solar panels positive terminal to inverter
’s positive terminal, and negative to negative.
And you must screw up the nut to avoid the bad contact.
