About Batterijsimulator

A reliable, free and transparent tool to support complex energy decisions.

About the maker

I'm an energy engineer with 10 years of experience in the energy sector. Throughout my career, I've seen how hard it can be for households to make well-informed decisions about energy technology such as home batteries.

With this tool, I want to help people make complex decisions based on reliable, transparent calculations. The simulator is free and will stay free.
