Frequently asked questions
How do I know which inverter size I need?
Add up the wattage you want on backup (fans, lights, TV, router) and add 30% headroom. Our technician does this calculation free during the site visit.
How long does an inverter battery last?
A good tubular battery lasts 4–5 years with regular distilled-water topping; flat-plate batteries typically last 2–3 years.
My inverter beeps and gives no backup — is the battery dead?
Not always. It can be a blown fuse, loose terminal, failed charging section or a single weak cell. We load-test before advising a replacement.
Do you provide same-day service?
Yes — in most areas of Delhi NCR we dispatch a technician within 2–4 hours of your booking during business hours (8 AM – 9 PM).
Is there any warranty on the repair?
Yes. We provide up to 90 days warranty on repair work and 6–12 months on replaced spare parts, depending on the component.
Do you charge a visit fee?
A nominal inspection charge applies. It is fully adjusted in the final bill if you go ahead with the repair.
