Enphase Energy System
Complete home energy, powered by the sun.
Enphase is a global technology company focused on solar, battery storage, and EV charging for homes. I was the lead industrial designer on three core components of Enphase’s fourth-generation hardware, helping define a new visual design language across the product line. Working closely with UX and engineering teams in the U.S. and India, I led concept development, form exploration, ergonomics testing, prototyping, and design for manufacturing.
Together, the system is designed to integrate seamlessly into modern homes while withstanding the demands of outdoor installation, reducing on-wall clutter and simplifying the installer experience.
From left to right, the IQ Battery 10C stores energy for home backup, the IQ Combiner 6C centralizes connections for a cleaner installation, and the IQ EV Charger 2 adapts vehicle charging to available solar power.
IQ Battery 10C
Modular backup power for your whole home.
Designed to store and deliver power for the home, the IQ Battery 10C was the first product developed in Enphase’s new hardware generation and set the foundation for the system’s design language. The battery system is modular, allowing homeowners to create a cost-effective system tailored to their needs and scale capacity over time.
As industrial design lead, my focus was to create a product that integrates naturally into residential spaces while meeting the demands of outdoor installation.
Concept exploration centered on developing a form that remains visually cohesive when patterned on a wall. A slightly pillowed front surface was chosen to help guide the eye smoothly from one battery to the next.
A weighted prototype simulated real-world installation of the 120lb battery, guiding the placement and ergonomics of primary lifting affordances.
Through extensive prototyping, I developed a clear, lockable cover that provides visual confirmation of power status, along with a magnetically latching solution for safe cable disconnection during service.
Informed by insights from Enphase’s network of professional installers, we validated conduit entry, clearances, and service access across a wide range of installation scenarios.
Material studies evaluated color, texture, and branding visibility under varying outdoor lighting conditions. The front surface finish was tuned to subtly reflect its surroundings without harsh highlights, while powder-coated black sides visually slim the unit and quiet unnecessary details for a premium yet durable appearance.
IQ Combiner 6C
All the connections in one box.
The IQ Combiner 6C consolidates solar, battery, and EV charger wiring into a single enclosure, significantly reducing wall clutter and installation complexity.
The enclosure balances thermal performance, weather resistance, and installer flexibility within a compact, residential-friendly form. It maintains a NEMA 3R weather-resistant rating while supporting conduit entry from nearly every direction, adapting easily to a wide range of site conditions without additional hardware or workarounds.
We designed integrated thermal venting to support reliable outdoor performance and developed a low-profile, double-pivot latch that delivers even seal compression while remaining hidden beneath the enclosure’s lid.
By consolidating multiple functions into a single unit, the IQ Combiner 6C reduces installation steps and requires 62% less wall space compared to earlier generations.
IQ EV Charger 2
EV charging built for solar.
The IQ EV Charger 2 delivers fast, intelligent EV charging designed to utilize available solar and home energy systems. Built on a modular platform, the charger supports multiple global charging standards and installation styles while maintaining a clean, minimal presence.
We prioritized flexibility, allowing a shared core architecture to adapt across regions, connector types, and mounting scenarios without compromising performance or usability.
We explored cable management solutions across hardwired and socketed configurations, ultimately landing on a separate holster that improved mounting flexibility and kept the main enclosure clear of the often dirty charging cable.
With a standard 25-foot charging cable, storage quickly emerged as a key usability challenge. Iterative prototypes led to a solution that clearly presents the charging handle and allows excess cable to be easily wrapped and pulled free.
A built-in RFID reader allows homeowners to control charging access. I led the design and layout of the UI, using a dead-front display that conceals charge status and metering information when not in use to preserve a minimal front face.
Designed for year-round outdoor use, the charger performs reliably across a wide range of climates. A shared platform supports multiple North American and European charging standards without fragmenting the design language.
