Head of EU Distribution Product Management at Sungrow, Eleonora Potestio explains how PV inverters convert DC to AC, enforce grid codes, and serve as the plant’s control and data hub. From curtailment to compliance settings, inverters sit between panels, home or business loads, and the grid – driving efficiency, safety and visibility.
Europe’s diversity creates complexity: different grid codes, languages and service expectations. Eleonora outlines why interoperability is essential – PV inverters, batteries, wallboxes, smart meters and EMS must “speak” shared protocols. Standardization cuts integration time, lowers costs and enables consistent pre-/after-sales support across 25+ languages and markets.
Modern households add storage, EV charging and smart-home loads. Advanced control – dynamic limits, tariff-aware charging, flexibility markets – requires an energy management layer. Open APIs and tested integrations let EMS orchestrate PV inverters and third-party devices, moving beyond monitoring to real optimization and market participation.
Germany drives capacity and regulation; the Nordics (notably Sweden) lead in digital infrastructure and easy access to flexibility markets; Italy scales smart metering; the Netherlands tops solar per capita. Eleonora stresses: clearer standards and interoperability programs will speed multi-vendor rollouts and make future upgrades seamless.
“PV inverters are the brain of the plant, converting energy and enforcing grid rules while providing the data and control modern systems rely on.”
“Europe’s strength is also its challenge. Interoperability and shared protocols are how we integrate diverse devices, markets and languages at speed.”
“Advanced use cases – from smart charging to flexibility – need an EMS. Open interfaces let PV inverters and third-party devices work as one system.”
