Que: How do you assess the current state of India's solar inverter testing ecosystem compared to global markets?

Ans: Honestly, it’s a story of two speeds. India’s solar deployment has been phenomenal, the ambition is real, and the momentum is real. But when you look at where our testing and validation infrastructure sits relative to markets like Germany or the US, there’s still a meaningful gap. In those markets, rigorous validation is almost cultural, it’s built into how products are developed, not treated as an afterthought.

Here, inverter manufacturing is scaling fast, but the validation backbone hasn’t kept pace. Most of what’s available is imported, which creates its own dependencies. And as inverters get more sophisticated, handling grid support functions and managing bidirectional flows, the need to validate them under real-world conditions becomes non-negotiable.

The market opportunity gives you a sense of the scale we’re talking about: from roughly USD 427 million today to nearly USD 848 million by 2034. That growth will only mean something if we can back it with the confidence that what we’re deploying actually performs. That’s the problem we’re trying to solve.

Que: What gaps prompted Exeliq to develop GridX-120, and what does the platform offer?

Ans: GridX-120 came out of a lot of conversations. Over years of working with inverter manufacturers, a few things kept coming up: dependence on imported test rigs, long wait times, limited local support, and the need to stitch together multiple systems just to run a complete validation. That’s not sustainable when you’re trying to move fast.

But the deeper issue was this: manufacturers could run basic checks but simulating how an inverter actually behaves on the Indian grid with its voltage fluctuations and frequency deviations was genuinely hard. A lab environment under ideal conditions doesn’t tell you the full story.

GridX-120 was our answer to that. It’s a 120 kW automated validation platform that brings functional testing, HV testing, insulation resistance, earth bond, and long-duration burn-in into a single workflow. The programmable AC Grid Simulator can recreate real grid conditions rather than idealised ones. It also uses regenerative architecture, so up to 90 percent of test energy is returned to the grid which matters when you are running extended validation cycles. And critically, it comes with local engineering support, which is often what manufacturers need most.

Que: What risks arise when inverters aren’t adequately tested for real-world grid conditions?

Ans: A well-performing inverter in a controlled lab can still be a problem in the field. The grid doesn’t behave like a lab. There are voltage fluctuations, frequency shifts, sudden load changes and an inverter that hasn’t been validated against those conditions can trip unexpectedly, underperform, overheat, or fail to synchronise correctly.

These issues rarely show up on day one. They surface after deployment, sometimes months in, which makes them expensive and disruptive to address. And increasingly, this isn’t just about product quality, it’s about grid stability. As renewables take a larger share of generation, inverters are expected to actively support the grid during disturbances. That raises the bar for what validation needs to cover.

Que: How does advanced testing improve inverter reliability, performance, and lifespan?

Ans: The real value of advanced testing is that it moves problem-solving earlier in the development cycle to where it’s far cheaper and faster to fix issues. Grid simulation lets you observe how the inverter behaves across the range of conditions it will face in the field, and catch issues such as tripping behaviour, synchronisation gaps, thermal instability before they become field problems.

Safety testing, including HV, insulation resistance, and earth bond testing, builds the electrical integrity that long-term reliability depends on. And burn-in testing is where you catch the issues such as component ageing, thermal stress accumulation, behaviour over time. You simply can’t see those in short-duration tests.

Beyond catching problems, all this testing generates engineering insight. It helps manufacturers refine designs, tighten performance, and build products that hold up over a real service life, not just a commissioning checklist.

Que: How important is indigenous testing infrastructure to India’s self-reliance goals?

Ans: India’s PLI push has built roughly 144 GW of annual domestic solar manufacturing capacity. That’s a serious foundation. But manufacturing without indigenous validation is a half-built value chain. I often say: if manufacturing is the muscle of India’s energy transition, testing infrastructure is the nervous system. Without it, you don’t really know what you’ve built.

Dependence on imported validation systems means dependence on foreign supply chains, service schedules, and support ecosystems. Indigenous capability closes that loop. It lets us design, test, certify, and support products entirely within the country. That also has implications for export competitiveness and development speed, which matter as Indian manufacturers look to compete globally.

Que: What challenges do domestic manufacturers face in accessing high-quality testing facilities?

Ans: The challenges are layered. Cost and procurement timelines are the obvious ones. Imported systems are expensive, and lead times can derail product roadmaps. But the less visible challenge is support. Inverter development is iterative. You need to adapt test sequences as products evolve, add new validation routines, and troubleshoot in real time. Getting that kind of responsiveness from an overseas supplier is genuinely difficult.

What manufacturers are actually looking for and what we believe this market needs is a validation partner, not just a validation system. Someone who understands their product, can evolve with their roadmap, and can provide technical depth throughout the development lifecycle. That’s the gap we built Exeliq to fill, and it’s what GridX-120 represents.
