Classification: CPC G | IPC G

Claim 15:
16. A system, comprising:
a hub configured to wirelessly communicate with a plurality of power electronics modules, wherein each of the plurality of power electronics modules of at least a portion of the plurality of power electronics modules is associated with a corresponding photovoltaic panel; and
a controller that is physically connected to the hub and communicates with the hub via wiring that also carries power from photovoltaic panels to an inverter, wherein the controller is configured to:
obtain a configuration associated with at least one metering component installed at a site to be metered;
perform a metering component test including at least one of:
detecting phase assignment of the at least one metering component based at least on the configuration including by
discharging a battery by a predefined power amount on a first line;
determining whether a measurement on a first metering component changed by an expected amount;
in response to a determination that the measurement on the first metering component did not change by the expected amount:
determining that a measurement on a second metering component changed by the expected amount;
determining that the second metering component is on the first line; and
setting a phase adjustment factor for the second metering component to reflect the determination that the second metering component is on the first line;

in response to a determination that the measurement on the first metering component changed by the expected amount:
determining that the first metering component is on the first line;
setting a phase adjustment factor for the first metering component to be 1;
discharging the battery by the predefined power amount on a second line;
determining whether the measurement on the second metering component changed by the expected amount;

in response to a determination that the measurement on the second metering component did not change by the expected amount and a determination that the measurement on the first metering component changed by the expected amount:
determining that the first metering component is on the second line; and
setting a phase adjustment factor for the first metering component to reflect the determination that the first metering component is on the second line;

in response to a determination that the measurement on the second metering component changed by the expected amount:
determining that the second metering component is on the second line; and

setting a phase adjustment factor for the second metering component to be 1; and
detecting polarity of the at least one metering component based at least on the configuration; and

output information associated with the metering component test.
