Common Questions
RG Series (Gas Gensets) FAQs
What kVA range does the RG Series (Gas Gensets) cover?
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.
How do I choose the right model in the 25–125 kVA range?
Add up your running load in kW, divide by 0.8 (power factor), and add a 20–25% margin — 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.
Which engine powers the RG Series (Gas Gensets)?
Tata Motors engines. Rishabh Power Solutions is a GOEM (Generator Original Equipment Manufacturer) — we build, canopy, test, and support the complete genset around the engine, with ISO 9001:2015-certified manufacturing.
Can I get an AMC or CMC for a RG Series (Gas Gensets) genset?
Yes. We offer Annual Maintenance Contracts (scheduled visits and labour) and Comprehensive Maintenance Contracts (parts, consumables, and unlimited breakdown visits included) for all our gensets, with genuine spares. Details are on our Services pages, or raise a service request online.
