Abstract

An electronics module docking system includes docking member removably coupled to a photovoltaic module. The docking system includes a first connector port electrically coupled to one or more photovoltaic cells of the photovoltaic module. The photovoltaic module is selectively coupleable to the docking member. The docking system includes a housing to enclose an electronics module. The housing may include second connector port that is selectively engageable to the power electronics module. The power electronics module and the photovoltaic cells are electrically coupled to one another upon selective engagement of the connector ports. The inverter housing is receivable by and removably coupleable to the docking member allowing the inverter housing to be removably coupleable to the photovoltaic module.

First claim

a bottom surface having a second access opening defined therein, wherein the first access opening and the second access opening cooperate to define a passageway when the junction box is secured to the docking member;
a first connector port adapted to be electrically coupled to the photovoltaic module by a connector routed through the passageway; and
a second connector port adapted to be electrically coupled to a power inverter.

2. The power inverter docking system of claim 1 , wherein the docking member comprises at least one docking slot adapted to secure the junction box to the docking member.

3. The power inverter docking system of claim 1 , wherein the junction box comprises a port structure that includes the first connector port and the second connector port.

4. The power inverter docking system of claim 1 , wherein the junction box comprises a port structure having a first wall and a second wall perpendicular to the first wall;
wherein the first connector port is defined in the first wall; and
wherein the second port is defined in the second wall.

5. The power inverter docking system of claim 1 , wherein the junction box comprises a port structure having a first wall and a second wall parallel to the first wall;
wherein the first connector port is defined in the first wall; and
wherein the second port is defined in the second wall.

6. The power inverter docking system of claim 1 , wherein the connector comprises an electrical wire.

7. The power inverter docking system of claim 1 , wherein the second connector port comprises a plurality of electrically-conductive sockets.

8. The power inverter docking system of claim 1 , wherein the junction box is adapted to be removably coupled to the docking member.

9. The power inverter docking system of claim 1 , further comprising a housing adapted to be removably coupled to the docking member, wherein the housing includes the power inverter.

10. A junction box for electrically coupling a photovoltaic module to an electronic device, the junction box comprising:
a bottom surface having a first access opening defined therein, wherein the first access opening cooperates with a second access opening defined in a base of a docking member to define a passageway when the junction box is secured to the docking member;
