Solar Cables
Figure 4-3 PV Panel Wiring – 4 Panels
Figure 4-4 PV Panel Wiring - 6 Panels
Connect the PV panels together in two strings of 2 panels, as shown inFigure 4-3 or Figure 4-4. The panels
and cables are labelled.
If you have a multi meter check the voltage of each string to ensure each string has a similar voltage and the
same polarity. Check the voltages at C and E for string 1 and at D and F for string 2 before plugging into the Y
joiners. Also check that the resistance from each connector (C, H, G and F) to the framing is high (more than
120kΩ).
The cables are to be installed in conduit where they are accessible (within reach of the ground) and where
they are exposed to sunlight (not shaded by the panels or in the ceiling) except for the last 200mm where
they plug into the cabinet.
If using the boot to enter the ceiling space (refer to Figure 4-5) then place the boot under one of the panels
to help protect the entry from the weather and sun (do this before installing the panel).
Run the PV cables and earth wire from the Allied Solar AS-2560 to the solar panels on the roof placing the
cables in conduit in exposed locations.
