Preparation
Step 2: Screw the wall bracket on the wall
Step 3: Match the inverter with wall bracket
Below tools are needed before installation.
Installation tools: crimping pliers for binding post , screwdriver, manual
wrench and

driller.
b) Use the wall bracket as a template to mark the position of the 2 holes on
the wall.
c) Drill holes with driller, make sure the holes are deep enough (at least
50mm) for installation, and then tighten the expansion tubes.
d) Install the expansion tubes in the holes, and tighten them. Then install the
wall bracket by using the expansion screws.(

e) Hang the inverter over the bracket, move the inverter close to it, slightly lay
down the inverter, and make sure the 3 mounting bars on the back are xed
well with the 3 grooves on the bracket.
Note: Please refer to the details from the Quick Installation Guide.
Step 1: Unscrew the bracket from the back of the inverter.
a) The wall bracket is xed on the inverter, and the user should remove it

5.5 Connections of the Inverter
PV String Connection
The inverter has one-string PV connector. Please select PV modules with excellent
function and reliable quality. Open circuit voltage of module array connected
should be
＜
Max.DC (table as follow) input voltage, and operating voltage should
be within the MPPT voltage range.
Table3 Max. DC Voltage Limitation
Max.DC Voltage
WARNING!
PV module voltage is very high which belongs to dangerous voltage
range, please comply with the electric safety rules when connecting.
WARNING!
Please do not make PV positive or negative ground!
NOTE!
Please follow the requirements of PV modules as below:
Same type; Same quantity; Identical alignment; Identical tilt.
In order to save cable and reduce the DC loss, we suggest installing
the inverter near PV modules.
5.5.1 The Main Steps to Connect to the Inverter
DANGER!
Danger to life due to high voltages on DC conductors.
When exposed to sunlight, the PV array generates dangerous DC
voltage which is present in the DC conductors. Touching the DC
conductors can lead to lethal electric shocks.
Cover the PV modules.
Do not touch the DC conductors.
