The prospective buyer should look for reliability, high quality batteries, safety, convenience, after-sales support, and operation over wide voltage range in an inverter. The buyers should always go for a well established brand. Reliable inverters are normally available from companies having a good in-house design capability with excellent manufacturing infrastructure and certified quality systems.

Batteries from reputed manufacturers will offer longer life and better quality. Batteries fitted by local manufacturers or assemblers, though low priced, turn out to be more expensive in the long run for customers as they require high maintenance and frequent charging.

Keeping in mind the prevailing power conditions in this region, the buyer should look for features that ensure safe operation. Some of these are battery deep-discharge protection, battery undercharge/overcharge protection, battery charging at sustained low mains voltage of 160V and electronic overload/short circuit protection. The inverter must save electricity during battery charging and should be capable of charging batteries with varying profiles..

Buyers of inverters from local, fly by-night operators usually repent their purchase decision, as these operators may not be available for service and support afterwards.
