What Is The Recommended Principle Of Connecting The Battery First And Then The PV?

By Renogy User Experience Team Apr 24th 2023
  1. The controller is a step-down design, and the PV voltage is greater than the battery voltage. Connect the battery first and then PV. If the battery is connected reversely, it will cause irreversible damage to the controller.
  2. Not all the controllers connected to PV alone can light up the controller. In order to avoid the controller not working due to the reverse connection of PV, the battery is connected first.
