Inverters

India’s 500 GW renewable energy target by 2030 dominates every policy conversation. Capacity additions, auction pipelines, transmission corridors; these are the metrics that make headlines. But there is a quieter, less glamorous constraint that could undermine all of it: the country’s under-investment in testing and certification infrastructure for clean energy equipment.

China strongly criticized the EU’s ban on Chinese inverters in EU-funded solar projects, warning it could damage trade relations, supply chains, and Europe’s energy transition.

The new policy has already applied, and impacts billions in funding from the European Investment Bank on renewable projects including standalone and co-located storage.

A King Abdullah University of Science and Technology (KAUST) researcher whose lab has demonstrated up to 100% accuracy using a single hardware counter tells pv magazine that firmware-level detection of inverter attacks is technically viable – but today’s communication standards do not transmit the firmware‑integrity signal to operators.

The new inverter is designed around standardised 5 MW and 5.5 MW PV sub-arrays with the aim to reduce balance-of-system costs. It features a maximum efficiency of 99.0% and a high-voltage architecture of up to 1,600 Vdc and 1,000 Vac.

IT security firm Jakkaru has identified a vulnerability in microinverters from AP Systems that could enable a “kill switch” scenario, potentially shutting down tens of thousands of inverters simultaneously and disrupting grid operations.

Noida-based Involtics has launched the GTSI series of single-phase hybrid inverters (3 kW/3.6 kW/5 kW/6 kW) for residential solar applications. The inverters work seamlessly with solar panels, batteries (lead-acid and lithium-ion), and the grid to deliver continuous power for household loads.

The Industrial Accelerator Act says solar projects awarded through public procurements or other public support schemes would need to feature Europe-made solar inverters and cells within three years after the act becomes law. For battery energy storage systems, similar requirements would be introduced using a phased approach from one year after the act enters force.

The WTO ruled that U.S. clean energy tax credits under the Inflation Reduction Act violate international trade rules by giving domestic products preferential treatment over Chinese goods. The decision specifically targets the ITC and PTC Domestic Content Bonus Credits.

New documents reveal US government found only two cases of communications in Chinese inverters that differed from official documentation. The discrepancies were deemed “non-malicious” and “non-intentional” by investigators.
