A day with home storage
01 / Daytime
Solar production can supply your home first, with available surplus charging the battery. Energy use, battery settings, and your utility agreement shape where power goes next.
Solar→Home + battery
02 / Evening
Your battery can supply stored energy as solar production falls. Your chosen operating mode and backup reserve determine when it discharges; the grid can still supply additional power.
Battery→Home
03 / Grid outage
A compatible backup system isolates from the grid and supplies the circuits included in your design. Available charge, appliance demand, and solar conditions determine how long backup lasts.
Battery + available solar→Selected circuits
Designed around your priorities
The right battery plan starts with a conversation about your home, not a promise that one size powers everything.
Talk through my optionsStart with refrigeration, lighting, internet, and the other circuits you want to support. Larger appliances need a separate power and capacity review.
Review how much electricity you use and when. We consider daily energy use, outage priorities, and the reserve you want to keep available.
Confirm solar compatibility, electrical upgrades, installation location, controls, and the coverage included in your written proposal.
