JSI10KTL-12KTL-15KTL User Manual 

4.5 

Connecting inverter to PV Arrays

4.5.1 

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.  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 1000V 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 “9 Technical Specification”.

 

For  each  input  zone,  PV  arrays should respectively  have  a  homogenous

structure, including the same type, the same number, identical tilt and identical 

orientation.
