Whole-home backup, sized honestly
"Whole-home" means different things depending on your loads. See what it really takes to back up most or all of your house — and where load management saves you from oversizing.
What do you want to keep running?
A quick, honest backup profile in about a minute — no contact info needed to see it.
Step 1 of 3
When the grid goes down, what do you want to keep running?
Start with your goal — we'll tailor the rest around it.
No contact info needed to see your estimate. Multiple options. One better decision.
The honest variables
Usable capacity
The kWh you can actually draw — and how full the battery is when the outage starts.
Your real loads
Fridge and lights sip power; AC, water heaters, and pumps gulp it, with big startup surges.
Recharge strategy
Solar refills the battery by day — but storm clouds cut production when you need it most.

Build a backup plan that fits your home
Tell us what you need to keep running and we'll size an honest option — battery, solar-plus-battery, or another path. If staying as you are makes more sense, we'll tell you.
We compare the numbers. You decide. If solar isn't right for your property, we'll say so.
