Figure 4-9 NOT allowed: connect loads between inverter and circuit breaker
Table 4-2 Recommended AC output cable specifications
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 following figure：
