5.2 Connecting AC Output Power Cables
Connect the SUN2000 to the AC power distribution frame (PDF) or power grid using AC
output power cables. Ensure that the cable connections meet the requirements of the local
power grid operator.
Prerequisites
A three-phase AC switch needs to be configured outside the AC side of the SUN2000. To
ensure that the SUN2000 can safely disconnect from the power grid under abnormal
conditions, select an appropriate overcurrent protection device according to local power
distribution regulations.

Do not install a single circuit breaker for several SUN2000s.

Do not connect loads between the SUN2000 and circuit breaker.
Context
Flexible cables are recommended for ease of installation. The outer diameter of the cable
conductor should be less than or equal to 4.2 mm. Table 5-1 lists the specifications.
If the PID module is used in a PV array containing the SUN2000, verify that the working voltage of AC
cables to the ground is no less than 600 V AC, and that the voltage between AC cables is no less than
1000 V AC.
