ShiftCharge for Growatt batteries on Octopus Agile
Tariff-aware battery scheduling for Growatt home batteries on Octopus Agile, Cosy and other smart tariffs. Set it once and let it shift load to the cheapest hours.
Connect your batteryShiftCharge connects to your Growatt inverter through the Growatt cloud and plans your battery around tomorrow’s Octopus Agile prices, your solar forecast, and the way your household actually uses energy.
No HEMS box. No local install. You add your Growatt account once, point it at your tariff, and the daily plan looks after itself.
How ShiftCharge talks to your Growatt battery
ShiftCharge uses the Growatt OpenAPI to read live battery state and to set the daily charge windows your battery uses to decide when to import from the grid.
You stay in control: you can pause automation at any time and the Growatt app keeps working as normal alongside it.
What changes when you connect Octopus Agile
Once your Octopus account is linked, ShiftCharge pulls tomorrow’s half-hourly Agile prices as soon as they’re published and builds a fresh plan each evening.
The plan picks the cheapest import slots, leaves room for expected solar, and avoids charging through the most expensive periods of the day.
What you need
A Growatt hybrid inverter with a battery (e.g. SPH, SPA) and a working Growatt ShinePhone account.
A UK smart meter on Octopus Agile, Cosy, or another time-of-use tariff supported by ShiftCharge.
A solar PV system is recommended but not required — ShiftCharge still earns its keep on grid-only setups by buying low and avoiding peak.
Common questions
- Does ShiftCharge need a local agent on my network for Growatt?
- No. The Growatt integration runs through the Growatt cloud, so there is nothing to install on your home network. A local agent is on the roadmap for users who want to remove cloud dependency.
- Will it conflict with the Growatt ShinePhone app?
- No. ShiftCharge writes the daily charge windows the inverter already uses. You can keep the ShinePhone app for monitoring and ShiftCharge will not fight it.
- Which Growatt models are tested?
- The Growatt SPH and SPA hybrid ranges are the primary targets. If you have a different Growatt model and want to beta-test, get in touch through the community link.
