Your neighbors lost power for 72+ hours last year. Their food spoiled. Their well pumps stopped. Their security systems went dark. It doesn't have to be you.
You already know these problems. We have the solution.
SDG&E decides when your power goes out. No warning. No timeline. You're left in the dark—literally.
No power means no water. No showers. No toilets. No irrigation. How long can your family go without water?
When fires threaten and evacuation looms, your security cameras, gates, and communication go dead. When you need them most.
$500+ in freezer meat. Insulin that needs refrigeration. Medications that can't get warm. Gone in 24 hours.
SDG&E rates increased 40% in the past 3 years. They're not stopping. Your bill will only get worse.
Fuel runs out. Maintenance is constant. They're loud. They break. And they won't run your whole house anyway.
Solar + Battery Storage That Actually Works
The safest battery chemistry available. No thermal runaway. No fire risk. No cobalt. Certified to the strictest UL 9540A standards.
While Tesla Powerwall degrades after 4,000 cycles, our Guardian systems are rated for 16,000+ cycles. That's 40+ years of daily use.
Not just lights and a fridge. We size your system to run everything—AC, well pump, EV charger, workshop. Everything.
The most advanced hybrid inverters on the market. Seamless grid/battery switching in milliseconds. Your devices won't even notice.
Not 10 years like the big box competitors. Twenty-five years of full coverage. Because we build systems that last.
We're in San Diego County. When you call, you get us. Not a call center in another state. Not a chatbot. Us.

They have billion-dollar marketing budgets. We have better engineering. You decide.
Installation takes 2-4 weeks. If you wait until fire season peaks, you'll be at the back of the line while your neighbors have power and you don't.
