Your calculations stay in your browser.

This version runs calculations on your device. It does not send appliance lists, bills or calculator inputs to a calculator server, and it does not store them in browser storage.

Passing a load between tools

If you choose “Use this load to size a system”, the daily energy and connected load are placed in the destination URL. That URL can appear in browsing history and standard hosting logs. Avoid sharing it if you consider those totals private.

Hosting

The hosting provider may process standard request information, such as IP address and browser details, to serve and protect the website. This site uses fonts already available on your device and does not request fonts from an external provider.

Language preference

The selected language is included in page URLs. No calculator inputs are sent to a translation service.

Advertising and analytics

No advertising or analytics scripts are active in this version. If advertising is introduced, this page and any necessary consent choices must be updated to reflect the services actually used.
