Growatt Off-Peak Planner

iOS Universel / Utilitaires

Intelligently charge your Growatt battery with accurate solar forecasting!

View and control your Growatt battery and inverter system with a new easy to use interface!

Compatible with Growatt SPA and SPH series inverters. We are always looking to work with volunteers to add compatibility with other models.

Key Features:

• Off-Peak Energy Planning: Maximise your savings by intelligently charging your battery during off-peak hours. The app helps you determine the best charging strategy based on your energy needs and solar generation forecast.
• Accurate Solar Forecasting: Get detailed predictions for solar generation, battery usage, and energy consumption based on current conditions and historical data.
• Solcast compatible: Input a free API key from solcast.com for industry leading solar forecasting.
• Broad compatibility: Compatible with all energy providers and tariffs with a fixed daily off-peak period.
• Further support for Octopus UK's Agile tariff: We can charge your battery during your cheapest time blocks.
• Better UI: Stay informed with a real-time view of your home battery and solar performance with a much improved and simpler interface over the standard Growatt app.
• Customisable Alerts: Set reminders for when it's time to make your off-peak energy plan.
• Seamless Integration: Designed to work with Growatt SPA and SPH systems, ensuring seamless monitoring and control of your solar energy setup.

Growatt Off-Peak Planner empowers you with detailed data on how your solar system performs day-to-day. Avoid unnecessary grid charges, ensure your battery is always charged at the right time, and minimise wasted solar energy. It's not just about savings, it's about making smarter, greener energy choices.

We currently provide support for Growatt SPA and SPH inverters. Please contact us if you have a different model - we are looking to support more.

Quoi de neuf dans la dernière version ?

We have removed the "charging mode" option (battery care/energy optimiser settings). Feedback was that users didn't really understand it. The app will now automatically decide on a charging mode based on the new minimum charge target setting.

New settings to specify the minimum charge target and average daily usage manually. This reduces the amount of assumptions we have to make about your setup, and subsequently allows greater compatibility with a wider range of electricity tariffs and situations. Tracking this information directly from Growatt data was grossly misleading for users whose Growatt inverter could see the load from an EV charger, for instance.

Added more helper options with regards to the Solcast integration and a "contact support" button.

Fixed issue where sometimes the charge target was set to over 100%.

Several UI tweaks and stability improvements.
