Arrangement of photovoltaic module array, has filter arrangement designed such that alternating current harmonics abutting against direct current input of inverter is suppressed and not allowed to pass toward module array

摘要

The arrangement has an inverter (3) tapping generated direct current (DC) voltage (UDC) from a photovoltaic module array (10). A filter arrangement is connected between the inverter and the photovoltaic module array. The filter arrangement is designed such that alternating current (AC) harmonics abutting against the DC input of the inverter is suppressed and not allowed to pass toward the photovoltaic module array. The filter arrangement includes a capacitor, which is electrically connected to DC supply lines extending to the inverter from the photovoltaic module array.
