The inspection of the photovoltaic power generation system is mainly to conduct visual inspection of various electrical equipment and components, including battery components, Corrugated Roof Solar Mounting, junction boxes, controllers, inverters, system grid-connected devices, and grounding systems.

1. Inspection of battery components and brackets

Check whether the cell of the module has cracks, missing corners and discoloration (process problems); whether the surface glass is damaged or dirt; whether the frame is damaged or deformed.

Check whether the appearance of the Corrugated Roof Solar Mounting is flat and beautiful, whether the components are installed firmly, whether the lead wires are in good contact, whether the lead wire sheath is damaged, etc. Check components or phalanx for rust and loose screws.

2. Inspection of DC junction box and AC power distribution cabinet

Check the casing for corrosion, rust, and deformation. Whether the internal wiring is wrong, whether the terminal is loose, and whether the external wiring is damaged.

3. Inspection of controller and inverter

Check the casing for corrosion, rust, and deformation. Whether the terminal is loose, whether the input and output wiring is correct.
