Record the fault
Send the brand, model, displayed code and when the unit fails or trips.
COMPONENT-LEVEL DIAGNOSTICS
Multi-Brand Inverter & Online UPS Component-Level Repair
If your inverter trips under load, stops charging, or shows a blank display, we trace the fault to the inverter power stage, control board, battery bank, or connected electrical wiring.
What happens after you enquire
Confirm the diagnosis
Discuss the diagnostic findings, parts availability and quotation before repair work begins.
Review the testing
Ask which functions were checked under load and what to monitor after handover.
Hybrid solar inverter repair in Rawalpindi and Islamabad
When diagnostics identify a failed circuit or power semiconductor stage, we explain the proposed repair, parts availability, and cost before work begins. Every repaired unit undergoes staged load testing and thermal checks before handover.

Online UPS runtime and charging assessment
For an online UPS that cuts out prematurely or alarms on overload, we assess the connected load, rectifier/charger performance, DC bus stability, and battery capacity to determine what is limiting backup runtime.
