Common Questions
RK Series FAQs
What kVA range does the RK Series cover?
The RK Series spans 3.5 to 5 kVA across 2 models, built on Rehlko (formerly Kohler) 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 3.5–5 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 RK Series?
Rehlko (formerly Kohler) 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.
Is the RK Series CPCB-IV+ compliant?
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.
Can I get an AMC or CMC for a RK Series 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.
