About Sriram Agency

A power backup shop that still answers the phone after the sale

For twenty-one years Sriram Agency has kept lights, fans and shutters running through Chennai's power cuts. We started with tubular batteries and inverters; today most of what leaves the counter is lithium, because it lasts longer, charges faster and never needs a drop of water.

Everything we sell we also fit and service ourselves — solar panels, home UPS units, lithium and tubular batteries, generators, CCTV, D.T.H. and the everyday electrical goods a house runs on. Bring the old unit in and we will adjust its value against the new one.

  • Sales and service under one roof
  • Old goods exchange accepted

An estimate only. Real backup depends on battery age, charge level and how much each appliance actually draws. A mixie or a pump runs for a few minutes, not for hours — tell us and we will size it properly.

FAQ

Questions customers ask us

Yes — that covers the lithium home UPS, the lithium battery and the fitting at your house. If your existing wiring needs extra work we will tell you the cost before starting, not after.

The warranty is up to 60 months and a well-used unit commonly runs close to ten years. It never needs water, so most of what kills a tubular battery simply does not apply.

A mixie, yes — for the few minutes you actually use it. A motor draws a heavy surge when it starts, so tell us which appliances you want on backup and we will size the inverter for that surge rather than guessing.

Yes. Call or WhatsApp us with your area, and our technician visits, checks the load and the wiring point and gives you a clear quote before any work starts.

Yes — old inverters, batteries and electrical appliances are accepted against a new purchase. Show us the item or send a photo and we will tell you its value.

We work out of two branches — Pudupet in central Chennai and T.H. Road near Ponneri — and cover Chennai and the surrounding areas. Tell us your location and we will confirm.

Not sure which size you need?

One call and we will tell you what it costs and how long the fitting takes.
