Remote troubleshooting over WhatsApp
Most inverter problems are diagnosable from the screen — a fault code, a flashing pattern, or a mismatch between expected and actual production. Send us a photo or short description and we'll usually identify the cause in the first reply.
No call-out fee for the diagnosis itself. We'll only recommend an on-site visit if the issue genuinely needs hands-on work.
- Fault-code interpretation (FXX series and others)
- Production-drop investigation (low yield vs expected)
- Grid-disconnect / no-AC issue isolation
- Step-by-step recovery instructions over WhatsApp
On-site visits in Multan & nationwide
When the issue can't be resolved remotely, our technicians come to your installation. We carry standard test gear (clamp meters, IR thermometers, insulation testers) and the most common spare consumables so most visits resolve in a single trip.
Same-day or next-day scheduling for Multan and surrounding areas. Nationwide visits arranged on request — typically within 3–5 working days.
- Full system inspection (DC strings, AC side, earthing)
- Live measurement & thermal check
- Connector / MC4 inspection & replacement
- Written service report after every visit
Repair & component replacement
For inverter units that need bench-level work — failed cooling fans, blown capacitors, faulty DC fuses, control-board issues — we strip, diagnose, replace components, and bench-test under load before returning the unit to service.
We source components from local distributors and reputable suppliers. Quotes are provided up-front with a parts list before any chargeable work begins.
- Cooling-fan replacement (most common cause of derating)
- Capacitor & DC-fuse replacement
- Display / communication-board diagnosis
- Bench-tested under load before return
Installation review & commissioning
A second pair of eyes on a brand-new installation. We verify that wiring polarity, MPPT inputs, grid-protection settings, earthing, and inverter configuration match the system design — before you sign off the installer's invoice.
Particularly useful for net-metering systems where incorrect grid-code settings can cause repeated disconnects. Independent — we are not the installer, so the report is unbiased.
- String voltage & polarity verification
- Grid-code & protection-setting check
- Earthing & isolation-resistance test
- Written commissioning report
Monitoring-app setup & WiFi dongle
Solis Cloud and SolisHome give you real-time visibility into production, alarms, and historical yield — but the initial pairing trips up a lot of users. We get it set up correctly, set sensible alarm thresholds, and walk you through the app once it's working.
Done remotely over WhatsApp in most cases (about 20–30 minutes). On-site setup available if your WiFi router is in a difficult location.
- Solis Cloud account & plant creation
- WiFi-dongle pairing (S1 / S2 / DLS series)
- SolisHome / Solis Cloud app walk-through
- Sensible alarm thresholds & reporting setup
