Commissioning Checklist for a Solar-Plus-Storage System

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.
