Additional Panels - Can I add more panels to my system?
Last Updated 3 years ago

Can I add more panels to my system?

This is a fairly complex assessment, but there are some basic rules to keep in mind:

  1. Total panel wattage should not exceed the controller's maximum wattage rating. (i.e. your charge controller rated for 1200W should not handle more than 12 100W panels)
  2. Total array voltage and amperage must not exceed controller rating. (Remember, Watts/Volts = Amps)
  3. Existing wiring must be of sufficient gauge for the additional amperage.
  4. Panels must be compatible, matching voltages for parallel connections.
