4.Electrical Connection

Outline of this Chapter

This section introduces the electrical connection for the product. Please read the

information carefully, it will be helpful to understand the grounding, DC input,

AC output and communication connections and requirements.

Caution:

Before performing any electrical connections, ensure the DC switch is OFF and

AC circuit breaker is OFF. Allow up to 5 minutes for the capacitor to be

discharged.

Installation and maintenance should be done by certified

electrical engineer

Attention

Before the electrical connection, use opaque material to cover

the PV modules or disconnect PV string DC switch. PV arrays

will produce dangerous voltage if it is exposure under sun

Danger

For this product, the open circuit voltage of PV strings should

not greater 1100V

Note

The connected panel must meet the standard IEC61730A

。
