Role
End-to-end product design: discovery, UX/UI, motion, design system, prototyping, usability testing.
Team
Designer–engineer duo, working closely with founders, support, and customers.
Overview
Powervault builds home batteries for solar and wind users. While the web portal exposed detailed telemetry, customers wanted clearer, app-first insights. I designed a new mobile app from scratch, with a live home view, clear totals (day/week/year), and charts that make complex energy data easy to understand. I also set design-system foundations, explored motion and 3D concepts, and used AI to speed up onboarding content and prototyping.

→ What I worked on
→ What I worked on
Discovery & Research: stakeholder interviews, portal review, light user survey (mixed confidence levels, many 55+)
Design Exploration:
Advanced/3D (tech-forward, interactive model, richer motion, inspired by best energy/EV apps)
Simple/Native (calm UI using familiar iOS/Material patterns for clarity & accessibility)
Design system foundations: tokens, buttons, reusable cards/tiles, chart components, states, motion guidelines, and light/dark themes implemented with carefully structured Figma variables.
Charts & data design: clear time ranges, energy balance (solar, battery charge/discharge, grid import/export) with plain-language labels and helpful tooltips.
Onboarding & comms: concise “how this works” screens, AI-assisted visuals for a short welcome video.
Prototyping & testing: interactive prototypes to validate hierarchy and readability, quick engineer loops for feasibility and performance.

Home (Live view)
- First glance system status (charging/discharging), plain language and visual indicators (Using solar + battery”).
- Subtle motion for state changes without added cognitive load.
Charts
- Time ranges: live/daily/weekly/monthly/yearly with consistent legends and tooltips.
- “Energy balance” visualisation that’s readable at a glance, but detail-rich on tap/hover.
- Multiple chart views to suit different user goals.

- Designer–engineer duo to validate feasibility early (data calls, chart performance, offline states).
- Structured handoff with component specs, tokens, and motion references.
- Quick, testable prototypes for feedback from support and a small customer group.

Designing for home energy is a balance of clarity and depth. We explored a tech-forward 3D route and a simple/native route; user feedback favoured the calmer approach, so we shipped that while keeping 3D for a potential pro mode. Early system work kept the product refinement fast, AI and motion helped explain complex states. From telemetry to everyday understanding, a clear, app-first experience with a system that scales.
