Rishabh Instruments is the world’s largest maker of analog panel meters - those needle-and-dial instruments that still monitor electrical systems everywhere - but that is just the most visible edge of a quiet, 40-year-old engineering group built on a single idea: measure, control, and optimize the flow of electricity. Founded in Nashik in 1982, the company transformed itself through a series of acquisitions, most decisively the 2012 purchase of a loss-making Polish electronics and die-casting business that it restructured into its most profitable arm, and it now ships more than 145 product lines to over 3,000 customers across 100 countries. The recurring approach is vertical integration - 99% of manufacturing is done in-house, from plastic moulds to finished circuit boards - which lets the company control quality, customize products, and absorb shocks that trip up competitors who outsource.
Business segments
Three engines at different stages - a global instrumentation platform that is the group’s backbone, a nascent solar inverter business that just turned profitable, and a European die-casting operation being deliberately reshaped for higher margins - all fed by the same in-house manufacturing backbone.
1. Electrical and electronic instrumentation: the group’s global measurement backbone
A vast catalogue of devices that monitor, protect and control electrical systems, sold through a multi-brand, multi-country network where the company often holds the number-one slot in niche categories.
- World’s largest in analog meters - the company holds the absolute number-one global position in analog panel meters, a product line with complex mechanical movements that is no longer feasible to manufacture in Europe, generating roughly ₹40-45 crore in revenue.
- A product for every point in the electrical network - the portfolio spans analog and digital panel meters, multi-function meters, current transformers, rotary CAM switches, temperature controllers, transducers, data loggers, protection relays, power quality analyzers, and even radiation-monitoring gates installed at airports and border checkpoints.
- Software now wraps the hardware - the August 2024 acquisition of Microsys in the Czech Republic added the PROMOTIC SCADA visualization system for industrial process automation, so the company can now bundle its instruments with software that takes inputs from its own devices and others on a factory floor to enable analytics and decision-making.
- Three channels, one short order book - products reach customers through 339 authorized distributors/stockists globally, direct sales to OEM panel builders, and tenders, with a firm order book that typically covers one to three months of average sales.
- Poland is the profit engine - Lumel SA, the Polish electronics subsidiary, contributed 51% of the group’s consolidated profit after tax in FY26 with a 23% EBITDA margin, and has been the most popular brand in Poland for meters, controllers and recorders for five consecutive years.
2. Solar string inverters: a homegrown bet on rooftop solar
The first company in India to design, develop and manufacture solar string inverters end-to-end, now operationally profitable after a redesign for high-volume production.
- First-mover in Indian-made inverters - the company was the first in India to build solar string inverters entirely in-house, covering single-phase units from 2.5 kW to 6 kW and three-phase units from 3 kW to 20 kW, with development continuing up to 120 kW.
- Turned profitable by redesigning the box - the single-phase inverter was redesigned from metallic enclosures to aluminium die-cast housings and re-engineered for high-volume manufacturing, moving from hundreds to thousands of units, which helped the business reach breakeven in recent months as of August 2025.
- Sold under its own brand and inside others’ - the company sells inverters under the Rishabh brand and also supplies semi-knocked-down kits to Indian brands that sell under their own labels, while reaching smaller EPC companies directly through its existing distribution network.
3. Aluminium high-pressure die casting: a European foundry being deliberately reshaped
A Polish plant that melts 20 tons of aluminium a day into precision castings for car compressors and industrial equipment, now exiting low-margin automotive contracts to chase higher-margin non-automotive work.
- 35,000 castings a day from one roof - the Lumel Alucast facility in Zielona Góra spans 17,000 square metres and houses a foundry, CNC machining, a dedicated tool shop and a laboratory, producing everything from aluminium housings for car compressors to cooler systems for battery aggregates.
- Half the portfolio is being deliberately shrunk - the business is phasing out loss-making legacy automotive contracts that were signed years ago and never revised for the energy and wage crisis in Europe, shrinking turnover by a planned 10.7% in Polish currency during Q2 FY26 as part of a planned transition.
- The target mix is 75% non-automotive - the freed-up capacity is being redeployed toward higher-margin non-automotive opportunities, with over 50 RFQs in progress, because non-automotive contracts provide much longer revenue visibility.
- A one-stop shop for Tier-1 customers - the plant is forward-integrated with high-precision CNC machining, surface treatment, powder coating, assembly of electronic elements, and testing, so it can deliver finished components rather than just raw castings.
Group structure and partners
A listed Indian parent with a multi-layered subsidiary chain across seven countries, where the Polish electronics subsidiary is the material profit contributor and European Union funds help finance factory upgrades.
- The parent company, Rishabh Instruments Limited, has been listed on BSE and NSE since September 2023 and sits atop a structure that reaches Poland, the USA, the UK, China, Cyprus and the Czech Republic through a chain of wholly or majority-owned subsidiaries.
- Lumel SA in Poland is the material subsidiary, contributing 51% of consolidated profit after tax in FY26, and has received EU co-financing for multiple projects including a new SMT line and development of innovative control and protection devices.
- The group’s operational entities split into two divisions: the electrical and electronic instruments division, which includes the Indian standalone business, Lumel SA, Sifam Tinsley in the UK and USA, Shanghai V&A in China, and Microsys in the Czech Republic; and the high-pressure die casting division, which is Lumel Alucast in Poland.
- Marquee customers include ABB, Siemens, Schneider Electric, Hitachi Energy, Endress+Hauser, Lucy Electric and L&T Electrical & Automation, while R&D partnerships with IIT Bombay and IIT Jodhpur extend the group’s innovation reach beyond its own R&D centres.
