4.5 Connecting DC Input Power Cables
Connect the sofar 30~40KTL
to PV arrays over DC input power cables.
Input mode selection
：
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.
sofar 30~40KTL
MPPT voltage range
DC inductance 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.

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.

Note
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.

If the two MPPT panels is independent, the input mode should be set as "independent
mode".
The setting method is introduced at chapter 6.3.
Independent mode (default):
If the two MPPT panels is paralleled together by combiner, the input mode should be set as
"parallel mode".
The setting method is introduced at chapter 6.3.
