The RT+ case
The fine print
Ratings per ISO 8528-1, standard reference 25 °C / 100 kPa / 30% RH. Full declared output holds well beyond the reference: Prime to 50 °C, COP to 40 °C, up to 1,000 m altitude, with no derating within those limits. RT+40 is rated Limited Prime. RT+62.5 is rated Prime with no COP. Scheduled oil change is 500 hours, while some competitors publish 700–750. We trade that interval for a 400+ dealer service network that actually reaches your site.
FAQ
The RT+ range accepts 68–80% of rated output in a single step depending on the rating (up to 20 kVA in one step on a 25 kVA set), and Rishabh publishes the exact figure for every rating. Block loading is what decides whether the set holds when a lift, compressor and AC bank restart together after a power cut.
The RT+ Series spans 20 to 125 kVA across 13 models, built on Tata Motors engines. Every model's full specification sheet is published on its own page in this section.
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.
No. RT+ sets deliver full Prime-rated output up to 50 °C ambient and COP/Continuous rating up to 40 °C, with no derating up to 1,000 m above sea level, well beyond the ISO 8528-1 reference conditions of 25 °C.
RT+25 through RT+62.5 can be supplied single-phase. RT+82.5, RT+100 and RT+125 are three-phase only.
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.
Every Rishabh genset carries a 2-year or 5,000-hour warranty with 1 + 4 free services (the industry standard is 1 + 3). The first scheduled oil change falls at 500 hours.
Yes. The series is CPCB-IV+ compliant. CPCB IV+ is India's strictest genset emission norm, mandatory for new diesel gensets since July 1, 2023, cutting PM and NOx by roughly 90% versus CPCB-II. It also keeps you eligible to operate during GRAP air-quality restrictions in Delhi-NCR.
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.
Yes. The entire RT+ range (25 to 125 kVA) meets CPCB IV+, mandatory for new diesel gensets up to 800 kW since 1 July 2024. RT+ sets are built as an authorised Tata Motors GOEM with genuine Tata engines, Stamford or Mecc Alte alternators and Deep Sea Electronics controllers.
