Thanks for your interest in Wonder Watt.
Wonder Watt is a service that allows predictive and smart charging and timed export of your Growatt or GivEnergy battery system based on tomorrow's forecast for your PV solar panel system.
That way, even during your off-peak window, you avoid charging your battery up to 100% if tomorrow is going to be a scorcher!
Equally, you can use timed exports more intelligently than manually adjusting schedules every day.
It's currently in beta and we're looking for people to test it out.
You can login with your Google account, and you will be able to configure your system settings.
