Single-phase Microinverter HMS-350/400/450/500-1T-NA
8. Technical Data
Be sure to verify the following before installing Hoymiles Microinverter System.
1. 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.
• We recommend that the maximum current rating at MPP should be equal to or less than the maxi-
mum input DC current.
2. The output DC power of PV module shall not exceed 1.35 times of the output AC power of the microinverter.
Refer to “Hoymiles Warranty Terms & Conditions” for more information.
