Plan your system

Choose which household loads to move into daylight

Start with one flexible task. Moving everything to noon can create a new peak without answering whether the change helped.

Find a task with a real choice of timing

Laundry, some water-heating schedules and discretionary charging may have flexible windows, depending on the equipment and household. Identify one task you can move without compromising its purpose or changing equipment safety settings.

Write its current window, alternative window, approximate energy and any constraints. A task needing supervision is only flexible when someone is available. Do not assume an unattended operating mode is appropriate because solar production is high.

Look for available energy, not just a sunny icon

Compare the task with the observed generation window and existing loads. Battery charging, household demand and export may compete for the same production. A high solar number alone does not establish unused capacity.

DOE’s solar and storage overview describes storage as a way to move energy between times. For your experiment, follow the measured paths rather than assuming every daytime watt is surplus.

One scheduling hypothesis

A task consumes about 1.2 kWh. You currently run it after sunset. On suitable days, your records show an approximately two-hour midday export window. Moving the task into that window may reduce later battery use or grid import. It is a hypothesis to check, not an automatic 1.2 kWh saving.

Choose a fair comparison

Record several ordinary days before changing the schedule. Then observe several days with the new timing. Note weather, occupancy, battery starting charge and other large loads. A cloudless trial day compared with a stormy baseline day says little about scheduling.

Use the same measurement boundary and interval. If the question is evening grid import, compare that interval. If the goal is preserving battery energy overnight, compare evening and morning battery observations alongside household consumption. These are different outcomes.

Avoid overlapping flexible jobs

Two moderate tasks may produce a demanding combined peak. Stagger them when practical, and stay within the system’s documented operating limits. Energy in kWh does not tell you whether simultaneous demand in kW is suitable.

Keep manual trials simple before considering any automation supported by your equipment. Sunstead’s current remote viewing is read-only; this guide does not imply it can schedule household appliances or control an inverter from the public website.

Decide whether to keep the change

  • Did the task still meet the household’s needs?
  • Did the chosen outcome improve across comparable observations?
  • Were there inconvenient peaks or unexpected battery effects?
  • Does the timing work in another season?
  • Can another household member follow the schedule?

Keep a one-line result: “On comparable clear days, moving this task to early afternoon reduced our measured evening import; cloudy days still need a different plan.” Include actual numbers only after collecting them.

If results are mixed, narrow the question. A partial improvement during one season can still be useful. Avoid converting a short experiment into a universal savings claim or a prediction of the electricity bill.
