Project Overview

This project was delivered for a solar inverter manufacturer. The goal was to provide a web-based end-user application that allows customers to monitor their solar electricity generation in a clear, modern dashboard.

The solution was built on the PST platform from M2MGO (People, System, Things) and extended with a connectivity layer to integrate inverter telemetry via MQTT. All collected data was processed and presented in a tailored monitoring experience for end users.

Business Value

The manufacturer received a tailored monitoring application based on an existing, proven CMS and workflow platform. This delivered strong value at an affordable cost, because the solution reused PST platform capabilities while still providing a product-specific end-user experience.

Key benefits:

• Fast time-to-market with a proven SaaS foundation

• Affordable implementation compared to building a platform from scratch

• A modern monitoring dashboard that improves customer experience

• Cloud hosting and 24/7 operations without internal infrastructure investment

What We Built / Solution

Connectivity & Data Integration

• Integration of inverter telemetry using the MQTT protocol

• Definition of the data model and mapping of inverter signals into the platform

• Support for the manufacturer in implementing the device connectivity layer to the PST platform

• Reliable ingestion and storage of time-series generation data

End-User Web Application

• Web-based monitoring app for customers

• Dashboards for:

  • current power output

  • daily / weekly / monthly generation

  • historical trends and performance overview

• User-friendly UI built on top of PST CMS capabilities, enabling fast delivery and easy future extensions

Architecture Highlights

The solution followed M2MGO’s SaaS approach:

• Hosted entirely in the Azure cloud

• Operated with 24/7 support

• Designed for scalability and low operational overhead for the manufacturer

This allowed the manufacturer to focus on product value and customer experience instead of building and operating a platform internally.
