Why is it important to set MeterValueSampleInterval to 1 second?

Real-time (1-second) data is essential because power meters can trigger shutoffs if limits are exceeded over a 1-minute interval. With second-level updates from each EVCS, dynamic load management (DLM) can respond instantly to demand changes, ensuring optimal control. In contrast, 30–60 second intervals risk outdated decisions, especially when managing multiple EVCSs. Accurate, high-frequency data enables precise, efficient load balancing across the entire site.
