Designed for home users, not industrial plant operators. Sunsynk's own apps are built for engineers managing dozens of sites — OpenSynk shows you exactly what you need, nothing more.

👁️

Monitoring only — your inverter stays in control

OpenSynk is a read-only monitoring tool. It connects to the Sunsynk API to display live and historical data from your installation. It cannot change charge schedules, inverter modes, tariff settings, or any other system configuration. Your Sunsynk inverter remains fully in charge of its own operation at all times.

Why OpenSynk

Built for homeowners,
not plant managers.

The official Sunsynk app and web portal are designed for installers and engineers managing large commercial fleets. OpenSynk is built for a family who just wants to know how their solar panels are doing.
