Short answer: On sale prices, UTL and Luminous hybrid inverters are the cheapest at 3 kVA and 5 kVA. Nexus is the better buy when the inverter will hang on a verandah or covered wall (IP54 enclosure), when you want 5 kW on a 24 V battery bank, or when you want to start on solar without a battery. Deye is the choice for a fully exposed wall with a 48 V lithium battery (IP65).
- Best for a verandah, 3 kW: Nexus INNO 9G 3 kW 24 V — IP54, battery-less start, 4-year warranty*, ₹50,400.
- Best 5 kW on 24 V: Nexus DEV HYD 5 kW 24 V — IP54, 4-year warranty*, ₹81,375.
- Lowest price, indoor mounting: UTL Sigma Pro 3 kVA 24 V (₹41,330 sale, 5-year warranty) or Nexus 3 kW 24 V (IP21, ₹44,048).

Where each brand is the better buy
- UTL: the lowest sale prices at 3 kVA and 5 kVA and a 5-year warranty on the Sigma Pro. Best when price is the main factor and the inverter will be indoors.
- Luminous: a large national brand with the TX range from 3 kVA up to 30 kVA. The 5 kVA TX is currently on a deep discount.
- Deye: IP65 enclosure and lithium battery communication on a 48 V bank. Best for an outer wall exposed to rain and dust.
- Nexus: a published IP54 enclosure at 3 kW and 5 kW for verandah or covered-wall mounting, 5 kW on a 24 V bank (two 12 V batteries instead of four), battery-less start so you can add batteries later, and component-level repair in India.
The spec most buyers miss: where will it hang?
An inverter mounted indoors can be IP21. On a verandah or covered wall it needs splash and dust protection, which is IP54. On an outer wall in the rain it needs IP65. Most price comparisons ignore this, and a wrong enclosure for the location is a common cause of early failure in the monsoon. If a brand does not publish an IP rating, ask for it in writing before you buy.
