This is mainly a personal preference: do you prefer to read the settings and data via a display or via an app? An app is very convenient if the charge controller is stored away; you will need a smartphone for the app. The apps are also free to use. There are also charge controllers with both an app and a display.
We supply various types of tools, such as MC4 crimping pliers, cable lug crimping pliers, MC4 toolsets, ferrule crimping pliers, and ratchet pliers. We also supply solar cable. The solar cable can be custom-made as well; please contact us for this.
