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.
AC breaker used as disconnect device,and the disconnect device shall
remain readily operable.
Caution
Context
All the AC output cables used for the inverters are outdoor three-core cables. To
facilitate the installation, use flexible cables. Table 4-2 lists the recommended
specifications for the cables.

Multi core copper wire
AC cable should be correctly sized to
ensure the power loss in AC cable is
less than 1% of the rated power. If the
resistance of the AC cable is too high,
it will cause a huge increase in the AC
voltage, which may lead to a
disconnection of the inverter from the electrical grid. The relationship between
power loss in AC cable and wire length, wire cross sectional area is shown in the
