Sentinel Solar

Edge telemetry for solar installations: an always-on local backend next to the inverter, not a cloud-only service.

Ownership: Owned by Red Sentra.
Availability: Deployed at installations. Source is private.
Stack: Go / PostgreSQL / Docker / Edge

The problem

A solar installation sits in a building, not in a data centre. Site connectivity is not guaranteed, and the inverter is a physical device that will not wait for the cloud to come back before it keeps producing data.

The system

An always-on local backend on a small computer at the installation, a Raspberry Pi class device, talking directly to the inverter and holding telemetry on site. Go services with PostgreSQL, packaged with Docker so the same stack deploys to every location.

My role

Backend and edge architecture.

Where it stands

The current architecture is local and edge-based. Anything network-wide is future work rather than something running today.
