In this expert insight, industry veteran Kunwer Sachdev discusses how Su-Kam's Electroscopy innovation transformed inverter quality disputes into a live, verifiable demonstration, shifting the market conversation from price to proven performance, and opening global export doors for Indian manufacturers.
The Problem Nobody Wanted to Name
At a time when low-cost Chinese inverters were flooding Indian and global markets, Indian manufacturers faced a textbook competitiveness trap. Their products were technically superior with higher efficiency, faster changeover times, and better battery protection, but price-sensitive buyers had no way to verify this on a showroom floor.
Chinese imports, aggressively priced, continued to gain shelf space. The question Kunwer Sachdev asked: what if we could let the customer see it themselves, live, in front of their eyes, in under five minutes? That question became Electroscopy.
What Is Electroscopy?
Electroscopy is a portable Comparison Tool Kit (CTK), a lab-grade power analyser in a 5 kg suitcase, that simultaneously measures two inverters across efficiency, changeover time, no-load consumption, backup duration, and cost-per-unit. It features a 16x4 LCD display for instant on-the-spot reads and a USB-connected GUI for any PC or laptop.
Key Highlights
- The Problem Solved: Chinese inverters undercut Indian manufacturers on price while concealing lower efficiency, higher no-load consumption, slower changeover times, and shorter real-world backup.
- Four Iterations to Market: The R&D team required four full development cycles to stabilise the hardware across wiring quality and battery chemistry variables.
- The Sales Impact: Electroscopy changed the retail conversation from which is cheaper to which actually saves me money, winning international distributor exclusivity agreements.
- Extended to Solar with Solarscopy: The same philosophy was applied to benchmark solar charge controllers (MPPT vs PWM), battery performance under solar charging cycles, and solar PCU conversion losses.
The India Angle for 2026
India's rooftop solar and home storage market in 2026 faces an identical challenge to the one Electroscopy was built to solve. With solar inverter imports dominating on sticker price, Indian installers and quality-focused brands need tools and narratives that help buyers see through the spec sheet. Solarscopy's methodology of live, on-site comparison of solar charge controllers, PCUs, and batteries is precisely the channel-enablement strategy that Indian distributors and EPC companies should be considering as rooftop solar deployments accelerate under MNRE's 2026 targets.
The Core Innovation Lesson
The most powerful marketing claim is the one the customer can verify themselves. Anything else is noise in a market full of noise.
