Model limits
This hourly view is a planning model. It starts at midnight with a full battery, assumes a constant base load, your inverter efficiency and idle draw, a 75% solar yield, no charging taper, weather variation or startup surge, and never charges above the usable capacity.
Use the result as a research brief.
These tools make assumptions visible so you can test conservative and favorable scenarios. They do not replace a product manual, electrician or measured appliance data.
