Why you need it

  • 📊
    Problems develop slowly
    A degrading battery, a failed solar string, or an overheating inverter rarely trip an alarm early. Wattson catches what your VRM dashboard does not show you.
  • 🔧
    Small faults get expensive
    A cell going out of balance or a string quietly dropping output is cheap to fix early and costly to ignore. Wattson flags issues before they become repairs.
  • 💰
    Cheaper than a service call
    One report costs less than an installer's callout fee. A monthly subscription tracks changes over time and catches seasonal issues before they compound.
