Connecting Inverter to PV Arrays

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 lighttight materials or disconnect the DC circuit
breaker. Exposed to sunlight, PV arrays will output lethal voltage.
Risk of damage to the inverter.
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.
Risk of damage to the inverter.
Make sure that the maximum short current of each string is less than maximum
input current. Please refer to chapter “APPENDIX”.
Due to only one MPP tracker for all DC inputs, Each PV string should have a
homogenous structure, including the same type, the same number, identical tilt
and identical orientation.
