Leap Frogging

WINAICO Panels have wire lengths designed to enable 'Leap Frogging', a technique used to reduce loose wiring and assist a compact installation. To learn more about the technique click here.

Water Resistance and Gaps

All solar panels made by WINAICO come with a Male and Female MC4 or QC4 connector. These connections are designed to be IP68 Water resistant rating, allowing water immersion for short periods of time but should be avoided for prolonged periods. Ensure that the connections are joined, with an audible click at installation and no gap like the following image.

Bending Near Connectors

Bending at the near the connectors should be avoided. This may lead to premature fraying and exposure, reducing the lifetime of the system. Ensure that bends of the wires have are sufficiently away from intersection point of the wire and the connectors as in the following image.

Panel Grounding and Earth Faults

All panels should be adequately grounded to ensure safety during lightning storms and rare electrical events with the solar panels. The panels come with grounding holes to allow a safe connection without the need to drilling into the panel.

However, an exposed wire can simulate a panel grounding and create an earth fault in the system. A way to reduce the risk of earthing faults is to remove the long return wire through the Leapfrogging wiring Technique.

This online tool is to provide installers with a more accessible summary of our WINAICO Installation Manual. Information provided should act as a guide only. If there is confusion, the PDF Installation Manual must be the main source for clarification.
