As part of the energy transition, every solar panel, battery system and charging station must be registered in a central national service. This registry holds millions of installations and is essential for grid stability. Our original architecture, however, was over‑engineered, hard to scale, and increasingly unable to handle the growing load.

In this talk, we share how we rebuilt this mission‑critical system without downtime and without breaking existing integrations, while shifting to a fully cloud‑native, non‑blocking and asynchronous architecture. We’ll walk through the key design principles we applied, decoupling, scalability, resilience and discuss the unexpected challenges where elegant theory met messy reality.
