The Enphase IQ Battery
Modular. Intelligent. Built to scale with your home.
Daytime production
During the day, your panels charge everything.
Complete energy independence
Solar panels make power. Batteries make freedom.
What happens when the sun goes down? When the grid goes down during a storm or PSPS event? Battery storage transforms your solar system from a money-saver into complete energy independence.
Nexus installs Enphase battery systems: modular, intelligent, and built to integrate seamlessly with your solar. Backed by 47 years of construction expertise.
How it works
Three modes. One system. Always covered.
Daytime
Solar powers your home. Excess energy charges your battery instead of going back to the grid.
Evening / Night
Battery powers your home automatically. No grid draw. No interruption.
Grid outage
Your home stays powered. Neighbors go dark. Battery + solar recharge keeps you running indefinitely.
Battery storage isn't just backup power.
It's freedom from rising electric rates. Freedom from outages. Freedom from the grid.

Battery storage FAQ
Questions homeowners ask before adding batteries.
Nexus is a certified installer for Enphase battery systems. Enphase provides modular battery solutions with flexible scaling options and whole-home backup capability. These systems integrate seamlessly with Enphase microinverters for optimal performance.
Solar panels generate energy during the day. Excess energy charges your battery instead of flowing back to the grid. At night or during outages, your home draws power from the battery automatically. Your essential circuits (or your entire home) stay powered.
Yes, with proper sizing. Multiple Enphase battery units can provide whole-home backup including air conditioning, EV charging, and pool equipment. We will design a system based on your specific energy consumption and backup requirements.
Backup duration depends on your usage. A typical home using essentials only (lights, refrigerator, internet, a few outlets) can run 12-24+ hours on properly sized battery storage. With strategic usage and solar charging during the day, backup can extend indefinitely during multi-day outages.
Yes. Nexus can retrofit battery storage to most existing solar systems. We assess your current inverter setup, panel capacity, and electrical panel to recommend the best battery option.
Enphase batteries carry a 10-year warranty with options to extend to 15 years. This is backed by the manufacturer and enhanced by our Nexus 25-year comprehensive warranty program.
