4.3. Connecting AC Output Power Cables

Connect the SOFAR 3.3K~12KTL-X to the AC power distribution frame
(PDF) or electrical grid using AC output power cables.

It is not allowed for several inverters to use the same circuit breaker.
It is not allowed to connect loads between inverter and circuit breaker.

Caution

Context

All the AC output cables used for the inverters are outdoor five-core cables.
To facilitate the installation, use flexible cables . Table 4-1 lists the
recommended specifications for the cables and the breakers.

Table4-1

The models marked with“ *” should be available only for some designated
countries.

Note: For the sake of safety, please make sure to use correctly sized cables,
otherwise the current makes the cable overheat or overload, even cause a fire.
