Case Study: Morningstar Corporation achieves reliable remote accessibility and a customizable web UI for off‑grid inverters with Mindgrub

Morningstar Corporation - Customer Case Study

Morningstar Corporation, a world‑leading supplier of solar charge controllers and inverters with over 4 million units installed globally, needed a reliable, remotely accessible user interface for its forthcoming 4 kW MultiWave™ Inverter/Charger so customers could control settings and review data for off‑grid systems in hard‑to‑reach locations. Mindgrub was engaged to design a customizable, card‑based web app UI that would be hosted on each device and work without an internet connection, ensuring usability and failure‑free remote control in extreme environments.

Mindgrub built an intuitive, metadata‑driven web app with Modbus integration, advanced TypeScript modeling, and a tiny site footprint that fits the smallest flash memory (avoiding added unit costs). The solution delivers near‑real‑time energy and power‑flow data, greater device customization, and easier monitoring and control for customers; Morningstar Corporation reports strong internal reaction from sales and marketing and a more competitive product position as a direct result of Mindgrub’s work.
