FAQ
The RG Series (Gas Gensets) spans 25 to 125 kVA across 8 models, built on Tata Motors engines. Every model's full specification sheet is published on its own page in this section.
Natural gas, LPG or biogas, on Tata-powered platforms from 25 to 125 kVA.
Add up your running load in kW, divide by 0.8 (power factor), and add a 20–25% margin, so an 80 kW load needs a 125 kVA set. If large motors start direct-on-line, allow roughly 3× the largest motor's kW as starting headroom. Our kVA calculator under Tools does this in seconds, or send us your load list for a free sizing.
RG model numbers reference the equivalent diesel platform, and rated output on gas is lower because of normal gas-engine derating.
