Factors Affecting Repair Cost

All prices shown here are indicative market ranges collected from local providers and are not quotations. Share your inverter model, battery capacity and the age of the system with the technician for an accurate estimate before work begins.

Maintenance Tips

1. 1Check electrolyte level every 45 to 60 days in summer and top up only with distilled water — never tap water, RO water or acid.
2. 2Fill only up to the maximum float indicator. Overfilling causes acid spillage and corrodes the trolley and floor.
3. 3Keep the battery in a ventilated area away from direct sunlight; every 10°C above 25°C roughly halves battery life.
4. 4Clean terminals every three months and apply a thin layer of petroleum jelly to prevent white sulphate build-up.
5. 5Let the inverter fully discharge and recharge once a month if you rarely have power cuts — batteries on permanent float charge sulphate.
6. 6Never connect a fridge, geyser, air conditioner, motor or induction hob to the backup circuit unless the inverter is rated for it.
7. 7Keep the inverter cabinet dust free and never cover it with cloth or store items on top; blocked vents burn boards.
8. 8Switch the inverter off at the mains if you are away for more than two weeks, but recharge fully before leaving.
9. 9Use a stabiliser or surge protection in areas with heavy voltage fluctuation to protect the inverter PCB.
10. 10Note the purchase date and warranty end date on the battery itself so you can claim before it expires.

Repair or Replace?

For inverters, repair is usually the right choice. A PCB fault, relay failure, blown fuse or fan replacement typically costs a fraction of a new unit, and a good technician can restore a ten-year-old inverter to full working order. Replace the inverter only when the transformer has burnt, when the board has multiple failed sections, when the repair quote crosses roughly half the price of a new unit of the same rating, or when your load has grown beyond its VA rating and you would be upgrading anyway. Batteries are the opposite — they are consumables with a fixed cycle life. A tubular battery typically gives three to five years in Indian conditions, flat plate two to three, SMF three to four and lithium eight or more. Once a load test shows capacity has dropped below about 60% of rated Ah, or the plates have hardened from sulphation, no additive or 'battery reviving' service will bring it back reliably. Be very cautious of anyone offering to 'recondition' a badly sulphated battery for a fee — occasional gains are temporary and the battery usually fails again within weeks.

How to Choose the Right Technician

1. 1Ask them to load-test the battery in front of you and show the meter reading before recommending replacement.
2. 2Get the recommendation in terms of your real backup need — list the exact appliances and hours you want covered.
3. 3Insist on a printed warranty card with the battery serial number, purchase date and dealer stamp.
4. 4Check that a new battery's manufacturing date is recent; batteries stored unsold for many months lose capacity.
5. 5Ask clearly what exchange value you are getting for the old battery and see it deducted on the bill.
6. 6Confirm whether the quoted price includes installation, cabling, lugs and the trolley or not.
7. 7For inverter repair, ask which component was replaced and request the faulty part back.
8. 8Prefer a provider who offers at least 30 to 90 days warranty on repair labour.
9. 9Verify they handle disposal through authorised recyclers rather than informal scrap channels.
10. 10Compare at least two verified providers before committing to a full system replacement.
