Buying advice

Choose a controller that matches your system size, voltage, and budget. MPPT units offer higher efficiency than PWM, especially for larger arrays. Consider built-in communications (Bluetooth, Wi-Fi, or Ethernet) if remote monitoring is important, and check the maximum input voltage and current to ensure compatibility with your panels.
