Inverter Inspection - 6 Month Preventive Maintenance

by Clancy Purdie, from the Community

This six month inverter inspection checklist supports preventive maintenance of power electronics inverters. Record title details such as inverter number, serial number, site, date, and preparer. Perform visual checks on enclosures, doors, cabling, wiring, air filters, and copper or aluminum plates. Verify AC and DC connections, control and DC power supplies, and LCL capacitors across modules. Add photos and document findings to track issues and corrective actions.

Solar Inverter and DC Isolator Inspection Checklist
This checklist guides technicians through a rooftop solar inverter and DC isolator inspection. It covers prestart safety and PPE, inverter identification, visual checks for damage and heat stress, removal of covers for internal inspection, and verification of cable condition and tight terminations. It also includes isolator checks for heat marks, moisture ingress, and enclosure integrity, with prompts to capture photos and document issues and corrective actions. Use it to ensure consistent, safe, and compliant solar PV maintenance.

RESCo End of Day Checklist
This end of day checklist for solar PV sites helps technicians complete shutdown and handover tasks. Verify fuses and combiners are closed and on, re-combiner breakers and DC and AC disconnects secured, inverter doors sealed, AC and DC disconnects on, and the inverter enabled and producing; record kilowatts and time observed. Check for inverter error codes, re-establish monitoring communications, confirm overall system status, and capture comments or action items with photos. Sign off with technician details and date.
