Connecting Inverter to PV Arrays
5.5.1
Safety
As input of the inverter in the PV power system, PV Arrays’ features should be paid
attention to. Please refer to PV module’s data sheet.
When designing PV arrays, following requirements should be met.
Lethal voltage exists!
Do cover the PV arrays with light-tight materials. Exposed to sunlight, PV arrays
will output lethal voltage.
There is a risk of inverter damage.
Make sure that the maximum open voltage of each string is within DC input
voltage range of the inverter. Voltage over 450V can damage to the inverter.
There is a risk of inverter damage.
Make sure that the maximum short current of each string does not exceed
maximum input current. Please refer to chapter “Appendix”.
PV string should have a homogenous structure, including the same type, the same
number, identical tilt and identical orientation.
