5.1.6 Each module (or series-connected string of modules) shall be provided with the maximum
series fuse, specified at 20A.
5.1.7 Modules with different electrical characteristics must not be connected directly in series.
5.1.8 Use a special solar cable and plugs for installing the PV system and make sure that all connections
are safe and tight. The cable should be minimum 4 mm2 (12AWG), and able to withstand the
maximum possible system open-circuit voltage.
5.1.9 Cables should be fixed to the mounting structure in such a way that mechanical damage of the
cable and/or the modules is avoided. Don’t apply stress to the cables. For fixing, use appropriate
means,
such as sunlight resistant cable ties and/or wire management clips specifically designed to attach to the
module frame. While the cables are sunlight resistant and waterproof, where possible, avoid direct
sunlight exposure and water immersion of the cables.
5.1.10 The junction boxes in these PV modules contain bypass diodes wired in parallel with the PV
cell string. The bypass diode in the junction box can prevent the degradation of component
performance caused by shading or covering (such as aging of packaging materials, sealing-off, etc.).
Refer to the junction box diode specifications provided in the relevant product specifications.
5.1.11 In the case of partial shading, the diodes bypass the current generated by the non-shaded
cells, thereby limiting modules heating and performance losses. In the event of a known or suspected
diode failure, installers or maintenance providers should contact Solahart. Never attempt to open the
junction box.
5.1.12 Do not connect different types of connectors.
5.1.13 Keep connectors dry and clean, and ensure that connector caps are hand tight before connecting
the modules. Don’t attempt making an electrical connection with wet, soiled, or otherwise faulty
connectors. Avoid sunlight exposure and water immersion of the connectors. Avoid connectors resting
on the ground or roof surface.
5.1.14 Don’t disconnect under load. When it is necessary to open the connector, make sure that the
component is in a non-working state, and must use a professional unlocking tool, and avoid pulling the
connectors hard.
