Kunwer Sachdev
Inventor & Indian patent-holder of Emergency Rescue Device (ERD) technology · Founder of Su-Kam (1988–2018) & Kunwwer.ai · Mentor to Su-vastika · Owner and funder of LiftInverter.com
LiftInverter.com is owned and funded by Kunwer Sachdev — the inventor and Indian patent-holder of ERD technology, founder of Su-Kam and Kunwwer.ai, and a mentor to Su-vastika, one of the brands this site compares. We state that plainly because trust depends on it.
The facts, stated plainly
- This site is owned and funded by Kunwer Sachdev — it is not a neutral third party.
- Kunwer Sachdev is the inventor and Indian patent-holder of ERD technology, the elevator-backup category this site documents.
- He mentors Su-vastika, a manufacturer that appears in our brand comparisons, but holds no shareholding or financial stake in it.
- He is the founder of Su-Kam (1988–2018) and Kunwwer.ai; he is no longer associated with Su-Kam (see the note below).
- Wherever a Su-vastika product is mentioned or compared, that relationship is disclosed.
- No manufacturer pays for coverage, placement, or ranking on this site.
About Su-Kam. Kunwer Sachdev is no longer associated with Su-Kam Power Systems Ltd. in any official or unofficial capacity. He founded and led Su-Kam from 1988 to 2018, but has had no involvement in its management, operations, or decision-making since, and any products, services, communications, or representations made under the Su-Kam name today have no connection to him.
What this site covers
Beyond backup power, LiftInverter.com covers lifts and elevator technology broadly — how they work, how they are installed and maintained, and the safety standards that govern them. We also track lift safety in India closely: we report news of lift accidents across the country and publish a factual review of every major incident as it happens, so that recurring and preventable causes are placed on the public record rather than forgotten.
Why publish anyway?
The ERD category is poorly documented, and most buyers are sized and sold by a single vendor in one conversation. A reference site — even one with a disclosed owner — is more useful than no reference at all, provided the method is transparent and the same for everyone. That is the standard we hold ourselves to.
How we handle the conflict
Ownership does not change the method. Every vendor, Su-vastika included, is evaluated against the same published criteria. Specifications, sizing math, and comparisons are shown openly so you can check them yourself rather than take our word for it. Where our interest and your interest could diverge, we tell you, and we leave the underlying numbers visible.
Attribution is not endorsement. We credit Kunwer Sachdev as the inventor of ERD technology because it is a matter of public record — and we disclose his ownership of this site for the same reason. Read the numbers, compare the brands, and decide for yourself.
