a replaceable photovoltaic inverter is mounted on each of a plurality of photovoltaic module for the conversion of direct current , produced by the photovoltaic cells , to alternating current . the inverter is coupled to a mounting bracket on the photovoltaic module such that is can be easily replaced . replacement of an individual photovoltaic module inverter can occur during continuous operation of the photovoltaic module system with minimal impact on overall power production . the inverter is also mounted apart from the photovoltaic module to facilitate heat transfer generated by operation of the inverter .
