Find Compatible Solar Panels for Your Inverter

Select your inverter and get instant compatibility results for every solar panel — with optimal string configurations.

The solar panel matcher automatically finds every compatible solar panel for your inverter. It checks voltage limits, MPPT range, and current ratings across your local temperature extremes, then calculates the optimal number of panels per string. Select your inverter, set your climate conditions, and get instant results — no manual calculations needed.

Need a full compatibility check?

Run a detailed safety check with temperature-adjusted voltage and current calculations.

Already have panels?

Find an inverter that fits your panel array with the right MPPT range and DC/AC ratio.

How does string sizing work?

Learn the engineering methodology behind these compatibility checks.
