the specified size to installation to fix the button.
Inverter should be installed in a well-ventilated location
3.2 Connection and Installation
If you open the bottom cover of the inverter, connection mode is as follow: according to
the difference of the patch panel capacity, please install it according to the manual and invert
er needs to be installed in the ground firmly
When input power is ready, connect the positive terminal (PV) [+] and negative
terminal (PV [-]) on inverter, and then get input power connected, wrong connection
will damage the inverter
Use crimping terminal and insulation cap when connecting inverter input and output
wrong connection will damage the inverter

11
Do not open the box, the interior of the inverter is with high voltage, it is dangerous to
touch

5. Maintenance and Repair
5.1 Initialization and Error
To prevent inverter stopped by accident caused by any error including buzzer ring or
wrong instruction display, please press “F-RESET” to stop the buzzer ring, and examine and
solve the fault, then rerun the inverter. You can confirm the faults scan, which stores 500
failure reasons from 0～499, the nearest one is the 0, and you can use top and bottom key
(△,▽) on keyboard to check whether the specification or other part is wrong.
5.2 Buzzer and Fault
1) Buzzer
Buzzer will ring continuous in any abnormal conditions like instantaneous overload, if
you cancel the overload, the buzzer will not ring. If you press the [BZ-off], the buzzer will
also stop ring and you press the key again, it will ring again, if the alarm doesn`t ring when it
has error, the buzzer will ring usually.
2) Over-voltage Fault
Please close the inverter to protect the system once the voltage of the solar array is over
the predetermined voltage.
3) Cancel Fault Warning
The error information will display from the screen and the buzzer will ring at the same
time if inverter is serious damaged. Press [F-RESET] and [BZ-off] can cancel the warning
and the error information, the transformer starts to count (300s, 5min). If the alarm rings
again, stop inverter; contact our company to fix the transformer.

5.3 Fault
Inverter will display fault and stop running if it occurs abnormally.
Alarm and abnormal content will display in keyboard LCD if it occurs abnormally
