MCB 10A 16A 16A 20A 20A 32A 40A 50A
MCB with rated fault current of 30 mA≤I
fn
≤300 mA should be installed between inverter and grid.
No load should be connected directly with the output of inverter.
Figure 12
Incorrect connections between Load and Inverter
Impedance of the AC connection should be less than 2Ω. To ensure anti-islanding function PV cable
should ensure power loss to be
＜
1% of nominal power. Also AC cable between inverter and grid
connection point should be less than 150m. Chart below provides relationship between AC cable
length and cross section with losses

AC Cable Loss for inverter
inverters come with good quality IP66 /IP68 AC connector. Please refer to information
below to make correct AC connection.
