Single-phase Microinverter User Manual
9. Technical Data
Warning: Be sure to verify the following before installing the Hoymiles Microinverter
System.
Verify that the voltage and current specifications of the PV module match those of the
microinverter.
The maximum open-circuit voltage rating of the PV module must be within the operating
voltage range of the microinverter.
The maximum current rating at MPP is recommended to be equal to or less than the
maximum input DC current. But the maximum short-circuit current must be equal to or less
than the maximum input DC short-circuit current.
The output DC power of the PV module is NOT recommended to exceed 1.35 times the
output AC power of the microinverter. Refer to the “Hoymiles Warranty Terms & Conditions”
for more information.
