2.4 Proper usage

n The inverter may only be used in grid-connected photovoltaic systems. The inverter is suitable

for use with all solar modules whose connections do not need to be grounded.

n In the installation solar modules that have an IEC 61730 Class A rating are required as the

inverter is non-isolated.

n If the maximum AC mains operating voltage is higher than the photovoltaic array maximum

system voltage then solar modules that have a maximum system voltage rating based upon the

AC mains voltage are required.

Note
