If you want to connect the photovoltaic modules by using the cables purchased by yourself, the
following requirements must be complied:
Cable installation should comply with all local regional and national regulations.
In some countries, an individual circuit breaker used between the solar panel and air
conditioner must be installed. So select a circuit breaker in accordance with local regulations,
and the rated current is more than 30A.
The electrician must identify the positive pole and negative pole. Reverse connection
may cause permanent damage to the air conditioner.
Use qualified photovoltaic cables only.
The cable can resist UV rays and climate of rapid change.
The rated voltage of the cable is more than 600V.
The cross section area of the cable depends on the maximum short circuit current and the
length of wire.
Be very careful when installing the cable at extremely low temperature.
Recommended to use the cable of cross section area of 4mm or greater, and the wire should
be as short as possible to reduce the energy consumption.
When the modules are connected in parallel, cables must be securely fastened on the support frame
which is used for mounting the modules to avoid wire slack.
