4.7 Safety check
Before the inverter operation, need to be examined for the photovoltaic array, Check Open
circuit voltage of the each PV array whether accord with the requirements.
Photovoltaic array
−Ensure Open circuit voltage of the each PV array accord with the requirements;
Ensure that the positive and negative polarity is correct.
DC connect
SOFAR 10-20KTL
Use the multimeter to check the DC side voltage and current;
Check the DC cable
，
Note the positive and negative poles cannot be reversed, Consistent
with the positive and negative pole of photovoltaic array, measured each input Open circuit
voltage
Compare the voltage, if the difference is greater than 3%, PV array line may be a fault
AC connect
SOFAR 10-20KTL
Ensure the AC breaker of the inverter is off
Check the inverter phase with grid is connected properly, Check the voltage of each phase is
within a predetermined range, if possible, Measure the THD, If the distortion is serious, the
inverter may not work.

4.6.3 Enable the DRMs function.
1. Connected the cables as shown below ;
2. Provided the DC Power through the PV Pannel until the LCD is working;
3. Set inverter country code as 02(Australia) in Enter Setting>Set Country Code(password 0001)
；
4. Enable DRMs function in Enter Setting>DRMs Control(password 0001);
5. Only DRM0, DRM5, DRM6, DRM7, DRM8 has been defined. Inverter will works as DRM0,
DRM5, DRM6, DRM7, DRM8 when Corresponding switch closure. Their priority is
DRM0>DRM5>DRM6>DRM7>DRM8.
