UTL vs Havells on-grid inverters
On warranty the two are level at 10 years. Where they differ is in what they publish: Havells gives maximum and European efficiency for each model, and UTL's page gives an MPPT efficiency figure.
Updated 26 September 2026
Havells is a large Indian electrical brand, and its Enviro GTi on-grid inverters run from home sizes to commercial ones. On warranty, it and UTL say the same thing, so the comparison moves to what else each brand gives you.
At a glance
| UTL | Havells | |
|---|---|---|
| Model compared | 3.3 kW on-grid, GT-3P3-GX-S1 | Enviro GTi 3000 NG and 3300 NG |
| Warranty | 10 years | 10 years |
| Maximum efficiency | Not published in these terms | 97.7% |
| European weighted efficiency | Not published in these terms | 97.2% |
| MPPT efficiency | Up to 99% | Not compared |
Havells publishes more of the numbers an engineer would ask for. European weighted efficiency in particular reflects how an inverter performs across a normal day rather than at its single best point, and Havells states it for each model.
Choose Havells if
- You want each model’s maximum and European efficiency in writing before you buy.
- You already use Havells for wiring or switchgear and prefer one electrical brand.
Choose UTL if
- You want the inverter, the panels and a later battery from one solar brand, priced as one system.
- You want it from a stocking distributor in Mohali, sized for your roof, from 3 kW upwards.

Questions we are asked
Is UTL or Havells better for an on-grid inverter?
On warranty they match: UTL lists 10 years on its 3.3 kW on-grid inverter, and Havells lists 10 years on its Enviro GTi range. Compare the quotes on price, service in your area, and whether the inverter comes with the rest of your system.
What efficiency does a Havells on-grid inverter have?
Havells lists 97.7% maximum efficiency and 97.2% European weighted efficiency on its Enviro GTi 3000 NG and 3300 NG. UTL lists up to 99% MPPT efficiency, which measures something else, so the figures cannot be compared directly.
Does RSK Solar Energy sell Havells?
No. RSK Solar Energy is a UTL Solar distributor. We can quote UTL on-grid inverters and help you compare them with a Havells quote.
