Connect the SOFAR 3.3K~12KTL-X to PV arrays over DC input power
cables.
Input mode selection
：
SOFAR 3.3K~12KTL-X has 2 MPPT, The two
MPPT can run independently, but also can be operated in parallel,
According to the system design, the user can choose the mode of MPPT
operation.
Independent mode (default):
If the two MPPT panels are independent, the input mode should be set as
"independent mode".
The setting method is introduced at chapter 6.3.
Parallel mode :
If the two MPPT panels are paralleled together by combiner, the input
mode should be set as "parallel mode".
The setting method is introduced at chapter 6.3.
Note
According to the inverter type, choose the inverter accessories (cables, fuse holder, fuse,
breaker etc.), SOFAR inverter with PV array should be excellent performance, reliable quality.
The open circuit voltage of PV must be less than Maximum DC input voltage of SOFAR
inverter, The output voltage of the solar array must be consistent with the MPPT voltage
range.
The positive and negative poles of the panel to inverter need to connect
fuse separately. The electric wire should choose PV cable,from the junction
box to the inverter, line voltage drop is about 1~2%, The inverter is
installed in the PV bracket, which saves the cable and reduce the DC loss.
Check polarity of PV array, to ensure the correct wiring of PV
array;
Please don't put the positive or negative of the PV array connect
to earth.
