From the project
A repository to do collective work on an open source micro-inverter.
- Having the first open source PV micro-inverter - Finally a design easy to repair that is no longer a black box - Redeem your data sovereignty, you will no longer depend on a proprietary cloud to follow your solar production and consumption.
- This project is propulsed by its community. - The collective work generated is meant to remain open. - Design files are made with open source software - Namely kiCAD. - Mechanical interfaces and components are modeled using FreeCAD. - Simulation files use ngSpice.
