How a repair visit runs

1. Customer sends pictures of inverter screen, panel layout, fault code on WhatsApp.
2. Initial diagnosis given on the same call (often resolves the issue without a visit).
3. If a site visit is needed, schedule confirmed.
4. Technician arrives with multimeter, clamp meter, IR thermometer, and common spare parts (fuses, MCBs, SPDs).
5. Live readings taken: panel string voltage, inverter input, AC output, battery voltage, earthing resistance.
6. Root cause confirmed. Fix done on the spot where possible. Spare parts ordered if needed.
7. Brief written summary sent to the customer after the visit.
