System and method for modular electric device having biased modular safety doors

An electrical system, comprising:

• a battery configured to provide DC power;
• an electrical connection to an electrical grid configured to provide AC power;
• a local power generation device configured to provide DC power;
• a power sink configured to receive AC power;
• and
• a modular inverter device configured to interconnect the battery, the electrical connection to the electrical grid, the local power generator and the power sink, the modular inverter device including,
• a plurality of module receptacles, each module receptacle including:
• a cavity configured to receive modular power device, such that the modular power device is aligned to engage a backplane;
• a rigid door member having a side and an edge, the rigid door member sized to cover an opening to the cavity to prevent exposure of the backplane;
• a hinge disposed on the edge of the rigid door member, the hinge configured to allow a swinging motion of the rigid door member;
• a latch mechanism disposed on the side of the rigid door member having a disengagement orifice and configured to hold the rigid door member in a closed position;
• and
• a disengagement mechanism disposed on the side of the rigid door member and configured to release the latch mechanism when a modular electric device penetrates the disengagement orifice, the modular electric device sized to prevent exposure of the backplane when engaging the disengagement orifice.

A method, comprising:

• aligning a disengagement protrusion disposed on a leading edge of a modular electric device with an empty module device receptacle configured to receive the modular electric device, wherein the empty module receptacle includes a latched module door having a disengagement orifice that is latched in a closed position and prevented from rotating;
• penetrating a disengagement orifice of the door with the disengagement protrusion;
• in response to the penetration of the disengagement orifice by the disengagement protrusion disposed on the leading edge of the modular electric device, releasing the door latch such that the door is free to rotate;
• rotating the module door to an open position by pushing the modular electric device into the empty module receptacle;
• engaging a backplane disposed in the receptacle with the modular electric device;
• and
• arresting a transient current with a transient current arresting circuit when the modular electric device engages the backplane.
