Built to make
technical work
more transparent.

Every tool is designed to explain how it works, with clear documentation of its methodology, assumptions, and intended scope where applicable.

Size your battery bank, solar array, and MPPT charge controller. Every output is traceable to a named formula.

Built for people who want to understand what a tool is actually doing.

Amperage Labs started from a straightforward idea: tools should show their work. Not as a feature, but as a baseline — because understanding a result is as useful as getting one.

Every tool here documents its logic, states its assumptions, and is upfront about where its scope ends. The goal is to support good decisions, not to replace the judgement behind them.

Open reasoning

Every output is traceable to the logic behind it, with assumptions documented. Nothing is hidden behind a "calculate" button.

Honest scope

Each tool explicitly states what it does not account for. Overselling accuracy is worse than useful precision.

No sign-up, no paywall

Core tools are free. Shareable configuration links, no accounts required, no data collected.
