An AC combiner box is used to connect multiple grid-connected inverters to a single power cabinet. It provides lightning protection and circuit breakers for each inverter output, ensuring safe and convenient access to the power cabinet.
Grid‐tied inverters feed power into the grid as AC current at the same frequency as the grid voltage. An “island” (aka, “islanding”) condition can occur due to a fault condition within the grid or when the grid shows a resonant‐load behavior.
The inverter disconnects from the grid depending upon the level and duration of leakage current detected. As a further safety precaution, in compliance with UL1741 CRD 2010*, the inverter conducts an isolation monitor interrupter self- test before connecting to the grid or every 24 hours, whichever is sooner.
The inverter “induces” a frequency variation by a injecting capacitive reactive power into the grid periodically. The time period during which the reactive power is fed into the grid depends on the required detection time (grid standard).
Any time the inverter is connected to the grid, the inverter circuitry continuously checks for ground fault conditions using a differential measurement of the AC phase (2W or 3W) lines searching for any values that would indicate leakage of current to ground.
