Never lose power again
Battery Backup & Hybrid Inverters
CFE outages keep getting more frequent as Baja's aging grid strains under growth. With Solar 1 battery backup, your home switches over in milliseconds — the refrigerator, internet and TVs never notice. No generator, no noise, no spoiled food, no dropped Zoom calls.
Uninterrupted power, automatically
Our systems transfer your home to battery power in milliseconds when CFE drops — so fast you'll only know because the neighbors' lights are off. When the grid returns, everything switches back and your panels recharge the bank for free. Saving money matters, but living your life matters more: a hybrid system gives you the best of both worlds — net-metering savings all year, and a home that stays on when the street goes dark.
Millisecond transfer
True UPS-grade switchover. Computers, routers and appliances never notice.
Up to 15-year warranty
Tier-1 batteries from multiple manufacturers with warranties up to 15 years.
Silent & fuel-free
No gasoline runs, no carbon monoxide, no 3am generator roar.
App monitoring
Watch production, consumption and state of charge from your phone.
Hybrid inverters: the brain of the system
A hybrid inverter manages solar, batteries and the CFE grid as one smart system: it powers your home with sunshine first, stores the excess, sells the rest to CFE, and islands your house automatically during outages.
And we're not tied to one brand. We install many inverter types — microinverter systems like Enphase, string hybrids, and all-in-one units — and match the technology to your home and budget, not the other way around.
Already have solar? We retrofit battery backup onto existing systems too.
Installed by certified electricians
Solar is only as good as its wiring. That's why every Solar 1 installation is managed by Gus at Baja Electrician — our #1 authorized installer — and carried out by his team of certified, insured electricians serving Rosarito, Tijuana and Ensenada, from panel upgrades to EV charger installation.

Frequently asked questions
How is this better than a generator?
Batteries transfer in milliseconds (a generator takes seconds to minutes), need no fuel, make no noise, require no maintenance runs, and recharge free from your solar panels the next morning.
How long will batteries run my house?
A typical 10 kWh battery runs essentials (fridge, lights, internet, TV, fans) for 12–24 hours. Sized right with solar recharging, you can ride through multi-day outages indefinitely. We size the bank to your actual loads.
Can I add batteries to my existing solar system?
Usually yes. If you have a grid-tie inverter we can retrofit a hybrid inverter or AC-coupled batteries — we work with many brands and system types. Send us your current setup for a free assessment.
