Reserve is the friendly number: 100% means the batteries are full, 0% means you've used everything you should — time to stop and let the sun refill them.
House rule of thumb: run big appliances while the sun is up — the goal is to end each day with a full battery. The banner up top does the math for you, using today's solar forecast: a dishwasher run costs about 1.5 kWh, a load of laundry about 0.5.
These are estimates, tuned conservatively. When in doubt, the status banner at the top tells you what to do.
