Claim:
1. A photovoltaic (PV) power generation apparatus, comprising: a wire box coupled to an alternating current (AC) system through an AC bus and to both a first direct current (DC) power source and a second DC power source; a first inverter having a first chassis attached to the wire box and being coupled to the first DC power source through the wire box, the first inverter comprising a first pass-through channel and a second pass-through channel electrically isolated from the first pass-through channel, wherein the first inverter is configured to convert DC power generated from the first DC power source into AC power that is outputted into the AC bus; and a second inverter having a second chassis attached to the first chassis and being coupled to the second DC power source through the first pass-through channel and the wire box, the second inverter comprising a third pass-through channel configured to allow a third inverter to be coupled to the wire box through the third pass-through channel and the second pass-through channel, wherein the second inverter is configured to convert DC power generated from the second DC power source via the first pass-through channel into AC power that is outputted into the AC bus, and wherein the first chassis and the second chassis are separate chassis and are stackable.
