Your solar system on iPhone, iPad, Mac and Apple Watch. See what your photovoltaic system is doing right now, get a forecast for the coming days and understand where your kilowatt-hours go. SolarDashboard uses your solar power to charge your electric vehicle, heat hot water with your heat pump or power HomeKit and Matter devices – so you keep more of your own green energy. SOLAR POWER, CONSUMPTION AND BATTERY AT A GLANCE Live rings show how much your system produces, how much your home consumes and how full the home battery is. Below: today, this month, this year and the total, with self-sufficiency and feed-in. Tap any day for its energy flow hour by hour: production, consumption, grid and battery. Widgets keep the most important values in view. ON YOUR APPLE WATCH A glance at your wrist: the rings show the solar power, consumption and battery level of your plant. Complications bring the values to your watch face and the Smart Stack. YOUR SOLAR FORECAST SolarDashboard calculates from the weather forecast how much your system will produce today, tomorrow and over the next seven days – hour by hour and self-calibrating to your plant. Optional notifications tell you in the morning what the day brings and when the sun comes back; the Energy Coach plans the week with you. INSIGHTS: UNDERSTAND YOUR SYSTEM Production and consumption for the week, month, year and all time, compared with the same period in earlier years. Your best and your weakest day, the strongest hour, your self-sufficiency day by day. A heatmap shows when your home uses energy, the base load at night reveals what runs all the time, and the battery analysis shows cycles, grid charging and what a battery would bring you. Savings, payback and CO₂ avoided tell you what your system is worth. Your solar year sums up records and savings – ready to share. CHARGE YOUR EV WITH SOLAR POWER Connect your wallbox and charge your electric vehicle automatically with solar power that would otherwise go to the grid. SolarDashboard adjusts the charging power and, where supported, the number of phases to the surplus. You decide from which solar power charging starts, which charge level to reach and how your surplus is used. Audi, Škoda and SEAT/CUPRA can be started directly – any other EV through a supported wallbox. HOT WATER FROM SOLAR POWER Connect your Viessmann, Vaillant or Stiebel Eltron heat pump and let SolarDashboard heat the hot water tank when there is surplus – or in the sunniest hours of the forecast. The app guards against short cycling. HOMEKIT AND MATTER ON GREEN POWER Run smart plugs, Shelly switches, infrared heaters, air conditioners or pool pumps with energy from your own system – automatically, once there is enough sun. SUPPORTED DEVICES • Inverters, balcony solar & batteries: SolarEdge, SMA, Huawei FusionSolar, Kostal, Growatt, GoodWe, Enphase, Fronius, Tesla Powerwall, Anker Solix, EcoFlow, Hoymiles – several vendors at once (Pro) • Home chargers: Alfen, Easee, Fronius Wattpilot, go-e Charger, NRGkick, SMA EV Charger, Wallbox Pulsar Plus, Zaptec • Electric vehicles: Audi, Škoda, SEAT/CUPRA • Heat pumps: Viessmann, Vaillant, Stiebel Eltron • Smart home: HomeKit, Matter, Shelly Devices in your home network are found automatically. FREE AND PRO Everything that tells you what your plant is doing right now is free: live dashboard, energy flow and battery for today, forecast for today and tomorrow, Insights for the current week, your solar year, the Apple Watch app, widgets and device setup. SolarDashboard Pro adds automation, history and money: charging and heating with solar power, months, years and comparisons, savings and payback, battery analysis, base load in depth, forecast in depth, notifications and the Energy Coach.
