Will Sunsynk work with Cosy or Go as well as Agile?

Yes. The planner is tariff-shape aware: any time-of-use tariff that exposes its rates in advance will work the same way on Sunsynk as it does on supported hardware today.

ShiftCharge for Sunsynk batteries on Octopus Agile

Tariff-aware scheduling for Sunsynk hybrid batteries on Octopus Agile is on the ShiftCharge roadmap. Sign up to hear first when it is ready.

Sunsynk hybrid inverters have a strong following with off-grid and prosumer setups in the UK. Sunsynk support is on the ShiftCharge roadmap and you can sign up today to hear first when it is ready.

How Sunsynk support is likely to work

Sunsynk exposes both cloud and Modbus interfaces. We expect to support the cloud API first for setup simplicity, with a local Modbus path later for advanced users.

The same ShiftCharge planner — Octopus Agile prices, solar forecast, learned demand — drives Sunsynk just as it does Growatt and GivEnergy.
