Why a Senga battery
Power you control. Rain, shine or outage.
A battery turns your home into its own small utility: store cheap daytime power, use it when PG&E charges the most, and ride through blackouts without noticing.
Beat peak rates every evening
Charge from solar or off-peak grid power, then run the house from 4 to 9 pm when rates spike.
Charge your EV from the sun
Stored solar charges the car overnight instead of expensive grid power.

We included a Tesla battery back-up system which should help our electricity bills and power our house in case of a black out.
Kathy & Clark S. El Dorado Hills, CA
Solar panels on the roof, plus a home battery. Very helpful, responsive and transparent throughout the whole process.
Eyal C. Solar + battery
The app easily tells you what is being generated and consumed from the panels, batteries and the grid.

Good questions
Straight answers, no sales pitch.
Still wondering about something? Call us. A real person in El Dorado Hills picks up.
Ask us anythingDo I need solar panels to install a battery?
No. Batteries work best with solar, but we also install them as standalone backup power and for shifting cheap off-peak grid power into the expensive evening hours.
Will a battery power my whole house during an outage?
That depends on the system size and your energy use. Most customers back up essentials like lights, outlets, fridge, Wi-Fi and medical devices. Whole-home backup is possible with the right capacity, and we will walk you through exactly what makes sense.
Which battery brand is best?
We work with Tesla Powerwall, Enphase IQ, FranklinWH and SolarEdge, all premium-grade. The best choice depends on your goals, energy habits and whether you already have solar.
Can I charge my EV from the battery?
Yes. Many customers store solar power during the day and use it to charge the car at night, saving even more.
How long do batteries last?
Most systems carry a 10-year warranty and are designed to last well beyond it. You get monitoring access and performance updates in the app.
