Connecting the AC output power cables
Connect the inverter to the AC power distribution network or power grid using AC power cables.
Do not use the same AC circuit breaker for multiple inverters.
Do not install loads between the inverter and the AC circuit breaker.
The switch used as a disconnection device should always be operational and
ready to operate.
In Italy, each grid-connected photovoltaic system with a power
output of more than 11.08 kW must be equipped with an
external interface device (SPI)
Warning
Context
All the AC power cables used for the inverter must be 5-pole outdoor cables. For easier installation, use
flexible cables. The table lists the recommended specifications for cables and circuit breakers.
