High-Stakes Energy Management for the Modern Nomad
Lumina is an embedded solar battery management system designed for off-grid RV living. By transforming complex power telemetry into an intuitive, high-contrast interface, the system empowers users to monitor, diagnose, and protect their energy infrastructure during critical travel conditions.
The Challenge:
In an RV, power is the difference between a seamless journey and an emergency. Existing battery management systems often overwhelm users with raw, technical data (voltage, amperage, watt-hours) that is difficult to parse while stationary, and nearly impossible to interpret while driving or in the dark.
For the Lumina system, the challenge was threefold:
The Approach:
To design an embedded interface that prioritizes actionability over raw information, creating a design system that feels stable, legible, and reassuring under high-stress conditions.

The Process:
Iterating Under Constraints
Designing for an embedded system meant that every UI element had a performance tax. My process was rooted in frequent prototyping to ensure that high-fidelity designs didn’t lag on the tablet hardware.
The Rejected Path:
High-Density Data Overload
Initially, I attempted to show all solar array data—voltage, current, temperature, and historical yield—on a single, dense screen.
Refining for the Environment:
I ran a “Vibration Test” by sketching UI components and placing them on a mock tablet to test touch accuracy.
The Design System:
To maintain consistency across a complex ecosystem of views, including high-level monitoring, deep-dive diagnostics, and emergency states, I developed a modular architecture. This ensured that whether a user was checking a Live Feed or running a Panel Scan, the mental model remained the same.
The Component Framework
I organized the system into three functional categories to ensure the UI remained performant on embedded hardware:
