We demand the connection must be
matching BYD’s, otherwise BYD don’t responsible for anything about
performance problem caused by your action.
4. Maintenance and Care
4.1General Maintenance
The following inspections of the modules should be carried out in
regular intervals:
(1) Regularly check the mechanical installation of the module.
Check the support equipment for fastness and symptoms of corrosion
or other damages. Check bolts and nuts for loosening, especially the
places with exposure to hard winds or at times of jolting. Ensure that the
fixing is fast and fasten immediately in places with some looseness. If
conditions permit the metal fittings that fasten or support the modules,
such as the bolts and nuts, should be protected from corrosion. A firs
inspection should be carried out 12 months after installation and
inspections every 10 years thereafter.
(2)Regularly check the electric wiring of the modules for reliable
connection to the components of the equipment and the grounding
system. Check regularly, if the value of the grounding resistance is still
reaching the designated requirement, If connections are not fast, fasten
them by soldering. After a thunderstorm or before the start of the stormy
season check the convergence box and the lightning protection
systems installed inside the equipment for loss of function and change
them immediately if necessary.
(3)Check cables, connectors and joints for current leakages and
deal with it, in order to prevent leakage currents caused by rainy or
snowy weather when checking the wiring, people must take insulation
equipment (such as tools and gloves etc,) with them and avoid touching
the bare parts of connectors or joints with bare hand, Check the system
for loosen parts of the connectors and fasten where necessary to
ensure good contact. Wipe the dust from the equipment regularly to
keep it clean.
(4) If the module appears in need of repair, the surface of the
module should be covered with fabric or other material. There is a
danger of high voltage, if the sun ray directly hit the module.
CAUTION:
If you come across loose connectors, please
contact Supplier or Maintenance and let them carry out
maintenance and care.
4.2 Module Cleaning
Excess dirt and dust accumulating on the glass surface of the
module can reduce its power output. Therefore BYD recommends
periodic cleaning of PV modules especially during times when the
modules do not have the expected power output.
The cleaning process
must be implemented after the PV modules are disconnected and
