see every watt, every string.

Monitor solar generation, export, import, and self-consumption in real time with inverter Modbus data, cloud dashboards, and proactive fault alerting.

The Brief

You can’t maximize what you can’t see

A renewable energy operator sought to maximize the output and return on investment from their solar installations. Without real-time visibility into generation performance, export/import flows, and inverter health, the team was unable to detect underperformance or faults promptly. The customer required a solution that integrated directly with their solar inverters to capture comprehensive performance data and enable proactive management of their solar assets.

The Solution

Inverter Modbus data, unified cloud visibility

From DC string diagnostics to export and self-consumption — continuous insight into generation performance and inverter health.

01

Direct inverter integration

Integrated directly with solar inverters to capture real-time data on energy generated, exported to the grid, imported from the grid, and self-consumed on site.

02

Modbus string diagnostics

Connected the IoT gateway to inverter controllers via Modbus to extract DC input power, AC output power, conversion efficiency, and string-level diagnostics.

03

Central IoT gateway

Aggregated generation and consumption data through a central IoT gateway and transmitted it securely to a cloud platform for unified monitoring.

04

Unified cloud dashboard

Delivered a cloud dashboard providing a unified view of solar generation alongside site load consumption, enabling real-time performance benchmarking against expected output.

05

Fault & deviation alerts

Configured alarm notifications for inverter faults, communication failures, and performance deviations to enable rapid response.

06

Historical trends & reports

Provided historical trend analysis and reporting to support performance reviews and maintenance planning.

The Dashboard

Generation, load, and inverter health in one view

Benchmark live output against expected yield, spot underperforming strings, and act on inverter faults before they erode return on investment.
