How the score helps

A fairer way to compare unlike products.

Compare within a real class

A compact inverter is compared with similar compact inverters—not a 300-pound jobsite machine.

Understand every number

The benchmark table adds a class median and percentile statement underneath each available key spec.

See the method

Missing data is excluded, scoring weights are normalized, and runtime is labeled as manufacturer-published.

Best generators for…

Shop the use case, not the biggest number.

Focused rankings screen the catalog for a specific load, location, priority, or budget—and publish the rules behind every shortlist.
