�� TYPICAL APPLICATIONS

• 1. The controller is 12V/24V auto-identification, when first installed, please make sure the battery has enough voltage so that the controller can be recognized as the correct battery type.
   

• 2. Install the controller as close to the battery as possible to avoid the voltage drop caused by the long wire, which will affect the normal voltage judgment.
   

• 3. The controller is only applicable to various lead-acid batteries (including open, sealed, gel, etc.), please do not use it for other batteries (including RI batteries, NiMH batteries, etc.).
   

• 4. This controller can only use photovoltaic panels as the charging source, please do not use DC or other power sources as the charging source.
   

• 5. The controller will be hot when running, please pay attention to install the controller on a flat, well-ventilated surface.

��️System connection

• 1. Connect the battery to the positive and negative side of the charge regulator

• 2. Connect the photovoltaic module to the positive and negative side of the regulator

• 3. Connect the user to the positive and negative side of the charge regulator.
   

• The opposite order applies when unloading!

• Improper sequence can damage the controller!
