Abstract
A method of dedicated circuit verification using a monitoring system includes measuring current at circuit breaker, comparing breaker current with microinverter current generated from one or more solar panels and determining whether they are within a threshold amount of one another, and generating an output based on the comparison.
Claims16
A system, comprising:
- an alternating current (A/C) diode configured to prevent or reduce power flow in an unintended direction;
- and
- a processor and non-transitory memory with instructions stored therein configured to detect a mismatch of a distributed energy resource generated current and a circuit breaker current and to generate an output if a mismatch is detected.
A system, comprising:
- an alternating current (A/C) diode including a relay and configured to prevent or reduce power flow in an unintended direction coupled with one or more solar panel microinverters, the microinverters coupled with a circuit of a building to provide power to the circuit;
- and
- a processor and non-transitory memory with instructions stored therein configured to detect whether the circuit is a shared with a power consumer based on detecting a mismatch of a distributed energy resource generated current and a circuit breaker current measured at a circuit breaker for the circuit, and to shut down the circuit when a shared circuit is detected.
