Step 1
To prepare the appropriate cable. The front of a wire stripping to will be in accordance
with the following picture size, and then through the PG waterproof joint.
Step 2
Insert sealing plug into housing, and tighten the screw nut.
Step 3
The cable stripped to the corresponding stem node hole.
4.5 Connecting DC Input Power Cables
Connect the 20~33KTL-G2
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.

According to the inverter type, choose the inverter accessories (cables, fuse holder, fuse, breaker etc.), 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 inverter, The output voltage of the solar array must be consistent with the MPPT
voltage range.

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".
