Pre-commissioning checklist for battery installs: Ten minutes of checks that prevent most warranty calls.

Most battery-related warranty calls trace back to a handful of predictable oversights at commissioning. A short, repeatable checklist protects both the system and your service schedule.

Battery commissioning checklist: DC polarity, terminal torque, firmware version, serial log and photo evidence
Battery commissioning checklist: DC polarity, terminal torque, firmware version, serial log and photo evidence

The checklist

  • Verify DC polarity and torque on every terminal before first energisation.
  • Confirm firmware versions on inverter and battery management system.
  • Record battery serial numbers and installation date in the commissioning report.

Photograph the installed system and attach it to the report. Six months later, that photo is the fastest way to close a support case.

Commissioning StepTarget Measurement / SettingPass Criteria before Handover
1. DC Polarity & Terminal TorqueMultimeter V_dc check (breaker open) + calibrated torque wrench (Nm)M8/M10 busbar & battery terminals torqued to 8–14 Nm per datasheet; zero reverse polarity
2. CAN-Bus / RS485 BMS LinkRJ45 pinout check (Type A vs Type B) + 120 Ω termination resistorInverter/GX displays real-time BMS SoC (%), cell temperature (°C), and CVL/CCL/DCL limits
3. Smart Meter CT OrientationVerify K→L arrow towards load/grid per manual + phase sequence L1/L2/L3Positive grid import when AC load is switched on; battery discharges to zero out grid meter
4. Firmware & Serial LogUpdate inverter + BMS to matched release; photograph nameplate & wiringArchive serial numbers, firmware versions, and photos in customer commissioning dossier
