Kunwer Sachdev: The Inverter Man’s Journey from Su-Kam to Su-vastika

For most people, a power cut is an inconvenience to endure. For one young man standing in that darkness, it was an opportunity hiding in plain sight. That man was Kunwer Sachdev. And what he saw in the dark, he spent the next three decades turning into light for homes, for hospitals, for small businesses, and for an entire country that had quietly accepted powerlessness as a fact of life.

How difficult was for a Country Running on Borrowed Light?

India in the 1990s was a nation in flux. Economic liberalisation had begun; ambitions were rising but the infrastructure had not kept pace. Load-shedding was relentless; businesses lost revenue, students could not study, families cooked by candlelight.

The inverter market existed in patches fragmented, unreliable, and ignored by serious capital. No dominant brand, no standardised quality, no real attempt to serve the vast middle class with affordable power backup. Into this gap walked a man with no engineering degree, no family fortune, and no blueprint. 

Just an extraordinary ability to read what people needed and an iron conviction that he could build it.

Kunwer Sachdev, Founder, Su-Kam Power Systems 

A brand that, at its peak, operated across more than 90 countries and redefined how India approached power backup. Born on 16 November 1962 into a middle-class family in Delhi, he grew up studying in a government school in Punjabi Bagh, where his father worked as a section officer in Indian Railways.

He carries two titles earned through decades of relentless work: "The Inverter Man of India" and "The Solar Man of India." He is featured in Connect the Dots by Rashmi Bansal which profiles 20 self-made entrepreneurs from modest backgrounds and in Making Breakthrough Innovations Happen by Porus Munshi, which highlights Su-Kam's role in creating India's inverter industry. He has been awarded the Government of India's Bharat Shiromani and Ernst & Young's Entrepreneur of the Year.

Today, after a turbulent exit from Su-Kam, he leads Su-vastika Systems a next-generation energy storage company proving that reinvention, not retirement, is his default mode.

The Earliest Education

There was no silver spoon. From an early age, Kunwer helped his older brother sell pens cycling through Delhi's neighbourhoods and riding buses to hawk writing instruments. It would be easy to call this hardship. Sachdev would call it his first MBA.

The street teaches what no classroom can: how to read a customer, handle rejection without internalising it, and find the right pitch for the right person. He completed his graduation in Statistics from Hindu College and an LLB from Delhi University. His dream of becoming a doctor remained unfulfilled after he was unable to pass the medical entrance exam. Instead of mourning the closed door, he went looking for the open window.

What if the Core Belief was – “Problems Are Just Products Waiting to Happen”

What made Su-Kam successful it was about paying attention to the daily frustrations of ordinary people, to the silent suffering of a family whose child could not study because the lights went out every night.

"You don't wait for opportunities; you create them." — Kunwer Sachdev

He saw the inverter as a product of dignity a way to give people reliability and control over their own environment. He understood that in a fragmented, trust-deficient market, brand credibility had to be earned through product quality, not manufactured through advertising.

What was exactly behind the Success?

No honest telling of Kunwer Sachdev's story can skip over what happened to Su-Kam in its later years. The company that once powered millions of Indian homes found itself unable to keep its own lights on financial distress mounted, insolvency proceedings followed, and legal scrutiny cast a long shadow over a brand that had been synonymous with reliability.

At 40, Sachdev had also faced a personal health crisis high blood pressure and the physical toll of building an empire at breakneck speed. The years of relentless work had costs that did not show up on balance sheets.

After parting ways with Su-Kam, Sachdev did something many entrepreneurs at his stage choose not to do: he started again.

Su-vastika Systems was born not as a rebranding of Su-Kam, but as a genuinely independent venture representing a strategic shift toward cutting-edge energy storage technologies.

Su-vastika focuses on lithium-ion and LiFePO4 battery systems, Battery Energy Storage Solutions (BESS), and advanced power electronics for solar and wind storage, grid stabilisation, and peak demand management with large-scale installations already serving hotels, hospitals, offices, and industry.

This is not a man running from his past. This is a man who studied it carefully, extracted every lesson, and aligned his next act with where the future was heading.

His Approach?

Field-First — Always in the field, meeting dealers, watching products work in tier-3 cities, not just labs.

Relentless Learner — Voracious reader. Mentors’ young entrepreneurs. Unusually willing to discuss failures alongside wins.

Trust Builder — Understood that word-of-mouth from a satisfied dealer was worth more than any advertisement.

The Takeaway

• Look at what the market is ignoring, not just what it is already serving.
• Don't wait for perfect conditions. Begin. Clarity comes from doing, not from planning in isolation.
• It is often the most direct path — if you treat it as a classroom rather than a verdict.
• Build trust with every person in your distribution chain. Your brand is only as strong as its weakest link before the customer.
• The business needs a builder who is still standing. His health crisis at 40 was a lesson he does not let others ignore.

The Challengers' Manifesto

Take a moment to imagine the distance between selling pens on crowded streets and building one of India’s most recognized power brands, how many rejections, sleepless nights, risks, failures, doubts, and silent battles must exist between those two realities?

Kunwer Sachdev’s journey was never just about inverters, batteries, or business expansion. It was about vision. About seeing possibility in darkness when the world only saw inconvenience. It was about carrying ambition even when circumstances were small.

From standing on the streets trying to sell a pen…

To understanding consumer behaviour…

To entering industries without privilege…

To building Su-Kam into a household name…

To facing downfall publicly…

And still finding the courage to rise again through reinvention…

Editor’s Note

Is it success alone?

Or is it the courage to continue moving even after life tests every ounce of your belief?

And most importantly, in the ability to see possibility where others only see limitations.

What makes Kunwer Sachdev’s story compelling to me is not only the rise of Su-Kam or the luxury that followed success. It is the fact that his journey reflects both ambition and adversity. He experienced remarkable growth, faced public setbacks, and yet chose reinvention over surrender.

And perhaps that is what being a Challenger truly means.

I believe journey like this matter because they remind people that extraordinary beginnings are often hidden inside ordinary struggles.

Every Challenger starts somewhere small. What separates them is the courage to continue when the path becomes uncertain.

And that is exactly why this story belongs to the Challengers section of BIGSTORY.
