The plug connector has its own polarity. Make sure that the connection is safe and tight. The plug
connector should not receive outer stress. Otherwise, it is only used to connect the circuit!
●
Use of suitable material
Use cable extensions and plugs that are designed for outdoor application. Ensure that they are in perfect
electrical and mechanical condition. Use only cables having one conductor. Select the appropriate cable
diameter to minimize voltage drop (to calculate the minimum cable diameter and the fuse, and to
calculate controls, multiply the Isc and Voc by a factor of 1.56).
If the module is connected to the control box, you must choose the control box with LJQ-1
、
LJQ-3 type
Connectors.

Maintenance and cleaning
●
Do not change the PV components optionally (diode, junction box, plug connectors )
●
Given a sufficient tilt (at least 15°), it is not generally necessary to clean the modules (rainfall will have a
self-cleaning effect). In case of heavy soiling (which will result in output reductions), we recommend cleaning the
modules using plenty of water (from a hose) without cleaning agents and using a gentle cleaning implement (a
sponge). Dirt must never be scraped or rubbed away when dry, as this will cause micro-scratch. We recommend
that the system be inspected at regular intervals.

Checklists:
●
All fastenings are tight and secure and free of corrosion.
●
All cable connections are secure, tight, clean and free of corrosion.
●
Cables are not damaged in any way.
●
Check the earthing resistive of metals.
