A system includes an output terminal to couple to an electrical load and a plurality of power supplies coupled in parallel. Each of the power supplies includes a controller configured to monitor a power output of a downstream power supply and a power output of an upstream power supply, maintain a standby state of the power supply in response to the downstream power supply providing power below a first threshold value, transition the power supply to an voltage regulation state in response to the downstream power supply providing power above the first threshold value, and provide a maximum power in response to the upstream power supply providing power above a second threshold value. The standby state represents a state in which a power output of the power supply is 0%, and the voltage regulation state representing a state in which the power output of the power supply is above 0%.
