standards and rules:
1) Use the ground hole on the frame for grounding. Do not use mounting holes or drill extra holes for
grounding on the frame. Otherwise, the rigidity of the frame may be insufficient.
2) The frame is a corrosion-resistant coated aluminum frame. When grounding, it is necessary to use
toothed gasket or self-tapping screw to penetrate the film to achieve a good grounding effect,
otherwise it may cause poor grounding.
3) Each module is grounded individually. For example, ensure that all modules of series are properly
connected at the beginning and end of each string. Do not ground one part in a single array.
4) The material, shape, size, buried depth, and grounding mode of the grounding body must comply
with the design specifications.
5) Before the thunderstorm season, check whether the grounding of the PV module is reliable, such
as whether the grounding cable is connected effectively and whether the anti-corrosion treatment
measures are intact. If necessary, dig the ground to spot check the corrosion of the underground
part.
6) The recommended grounding cable diameter must meet grounding requirements.
7) Anti-thundered measure should be taken to module series Photovoltaic grounding and lightning
protection should implement by regulation of DL/T1364.
5 Installation method
1. The modules which installed at one series should be same power
、
same color
、
same current.
2. If the modules must be gathered together, we suggest that the first mix colors, secondly mix current,
mixed power is not recommended.
3. Only high current modules can mixed into low current modules series.
4. The strapping tape of cable need to use scissors to cut open, can't catch the connector pull off.
5. If there is tape to hold the cables on the backsheet, remove it before installation.
6. During installation, the backsheet of the modules shall not be scratched.
7. Do not tread module in any case.
8. Where there are sandstorm, the module connector should immediately connect after a short period,
or do sand protection, avoid sand enter into the connector and affect the installation.
9. Recommendations for coastal applications of PV modules (Table 13).
