Is my system working? Designing

Is my system working? Designing the screen that answers it, for Morningstar.

Morningstar's solar charge controllers have a small web interface built in, called Live View. It showed every reading at equal weight, and the electricians using it kept asking the same thing: is it working, and is it safe? I redesigned it around that question: a status card first, output in context, a 30-day view that makes changes stand out, and a three-step setup that puts the settings that can damage hardware first.

It runs on the controller itself, so the whole thing had to fit in about 5 MB with system fonts only. https://liveview.figma.site
