Compliance
Note: Many utilities impose export limits (often 10 kW or system rating). Battery storage can absorb excess generation. Export limiting via inverter settings is common for compliance.

Reference

Net Export = Peak Generation - Min Site Load Battery Absorb = min(Battery Power, max(0, Net Export - Limit)) Remaining Export = Net Export - Battery Absorb Curtailed = max(0, Remaining Export - Export Limit) Daily estimates assume ~4 peak sun hours
