Commissioning Checklist for a Solar-Plus-Storage System
A structured commissioning workflow covering electrical checks, communication setup, battery activation, and grid-compliance verification before system handover.
Article context
Pre-commissioning checks
Verify all DC and AC wiring, check torque values on all terminals, confirm correct polarity, inspect grounding, and measure open-circuit voltage on each PV string. Take photos of all connections for your commissioning report.
Firmware and grid code
Update the inverter to the latest firmware. Select the correct country grid code—this controls voltage/frequency windows, ramp rates, and export limits.
Battery pairing
Power up battery breakers first, then the inverter. Select the battery brand and model, verify SOC and voltage readings, and run a short charge cycle.
Functional testing
Test grid-connected operation, simulated grid outage, battery charge/discharge limits, PV derating behavior, and monitoring platform connectivity.
Handover documentation
Provide a commissioning report, wiring diagram, warranty registration, monitoring login credentials, and a one-page quick reference guide.
