In this talk, we introduce µSolarVerter, our open-hardware micro-inverter designed to support decentralised solar production while giving users full control over the information their system generates. The project grew from a simple question: how do we make small-scale solar both understandable and adaptable, without locking people into a black box?

Our presentation will be split into three parts:

1. Design Journey — focusing on what people actually use

We’ll walk through the design process by following the things users interact with most: clear and accessible data, a flexible software layer, and a hardware platform that supports both without getting in the way. The story is about enabling insight and experimentation: good telemetry, open interfaces, and a control system that stays transparent, all backed by a converter designed to be efficient, safe and repairable without requiring deep power-electronics expertise. Hardware is there, but it’s not the centrepiece — it’s the foundation beneath a system meant to be explored, extended and trusted.

2. Deliverables — µSolarVerter as a platform

We'll show you how we made µSolarVerter as a platform, built with the intention of gathering a community around it. We will unveil our open documentation, open firmware and open data flows, making it easy to integrate with domotics systems like Home Assistant or openHAB, or to build your own dashboards and analysis tools. Users can experiment with their own production/load-matching logic, develop new applications, or simply keep their data fully local. The openness is practical: it’s there to be used, not just admired.

3. Invitation — unveiling the beta program

We will introduce our OwnTech beta program, inviting participants who want early access to the platform, to test it, review it, or contribute improvements. Whether you are interested in decentralised energy, open design, or taking a more active role in your own solar production, this is a chance to get involved from the start and help shape where the project goes next.
