Troubleshooting Your Solar System: A Comprehensive Manual

Understanding Solar System Components

Before diving into troubleshooting, it’s crucial to understand the main components of a solar system:

  1. Solar Panels: Convert sunlight into electricity.
  2. Inverter: Converts DC produced by panels to AC for use in your home.
  3. Batteries (if applicable): Store energy for later use.
  4. Charge Controller: Regulates the power going into the battery bank.
  5. Utility Meter: Measures the flow of electricity between your home and the grid.
