Battery Storage & Backup
Battery planning is not simply a count of appliances. It is a decision about runtime, simultaneous loads, motor starts, inverter capacity, and how the property behaves when the grid is unavailable.
Build My Backup PlanHomeowners, rural properties, and businesses seeking partial backup, whole-property backup, or a battery retrofit.
The right battery approach depends on what must run, for how long, what loads overlap, and what equipment must start under backup conditions.
See where your power comes from.
Pick a situation and watch the colored dots move. They show what a system like this is doing at that moment, and why a grid-tied system behaves differently from one with a battery.
Your solar powers your home first, tops off the battery, and any extra can go back to the grid, depending on your utility plan.
- Solar power flows to the inverter.
- Solar power flows from the inverter to your home.
- The battery is charging from solar.
- Extra solar power flows out to the utility grid.
Illustration only. A real design depends on your equipment, the loads you choose to back up, and a site review.
Questions that help shape the right next step.
Early planning does not replace final engineering, permitting, site evaluation, equipment selection, or contractual proposals. It gives those steps a more informed starting point.
Critical-load inventory and runtime priorities
kWh energy need versus kW power demand
Inverter output, surge, and motor-start needs
Existing solar, electrical equipment, and expansion opportunities
Common ways a system plan gets simplified too soon.
These are not reasons to delay a project. They are reasons to ask more useful questions before the property is committed to an approach.
Confusing capacity with output power
Planning for runtime but not start-up demand
Backing up every circuit by default
Skipping well-pump and HVAC evaluation
Organize the first inputs before a project review.
The separate Energy Planner considers usage, critical loads, storage, power, and runtime. Use it for a structured preliminary plan, then bring the results into a Project Review.
