Note: Modern monitoring captures 15-second data for performance analysis. String-level monitoring is standard for >100 kW systems. Plan 30% overhead for metadata and logs.
Reference
Inverter channels: 12 per inverter (V, I, P, etc.)
String channels: 3 per string (V, I, T)
Total points = Inv + String + Env + Meter
Data Rate = Total × (60 / Sample Interval)
Storage = Rate × 60 × 24 × 8 bytes × Days
