Micro-inverter assembly for use in a photovoltaic system and method of making same
A micro-inverter assembly for use in a photovoltaic system includes a housing, a direct current (DC)-to-alternating current (AC) micro-inverter disposed within the housing, and a DC connector electrically coupled to the DC-to-AC micro-inverter. The DC connector is positioned within a recess formed in a bottom surface of the housing such that at least one electrical contact of the DC connector is accessible from outside the housing. According to alternative embodiments, the DC connector comprises a plug-and-play connector constructed for one of a rotational engagement and a translational engagement with a DC connector of a photovoltaic (PV) panel.
1. A micro-inverter assembly for use in a photovoltaic (PV) system, the micro-inverter assembly comprising:
a housing;
a direct current (DC)-to-alternating current (AC) micro-inverter disposed within the housing; and
a DC connector electrically coupled to the DC-to-AC micro-inverter, the DC connector positioned within a recess formed in a bottom surface of the housing such that at least one electrical contact of the DC connector is accessible from outside the housing;
wherein the DC connector comprises a plug-and-play connector;
wherein the recess is sized to permit a mating DC connector of a PV panel to linearly translate, when fully inserted within the recess, between a first position and a second position within the recess; and
wherein the plug-and-play connector is disengaged from the mating DC connector of the PV panel in the first position and engaged with the mating DC connector of the PV panel in the second position.
2. The micro-inverter assembly of claim 1 further comprising an AC wiring harness electrically coupled to the DC-to-AC micro-inverter and extending through the housing, the AC wiring harness comprising a pair of AC lead wires, a neutral lead wire, and a ground lead wire.
3. The micro-inverter assembly of claim 1 wherein the recess is sized to permit the plug-and-play connector of the DC connector and a mating plug-and-play connector of a PV panel to be concealed entirely within the housing.
4. The micro-inverter assembly of claim 1 wherein the at least one electrical contact comprises a plurality of spring contacts.
5. The micro-inverter assembly of claim 1 wherein the at least one electrical contact comprises one of a pin connection and a slot connection.
6. The micro-inverter assembly of claim 1 wherein the DC-to-AC micro-inverter is coupled to the DC connector absent a wired connection therebetween.
7. The micro-inverter assembly of claim 1 further comprising at least one threaded insert located in a side surface of the housing.
