Application range

This controller is only suitable for ordinary solar modules. Please do not connect other charging power sources, otherwise the controller may be permanently damaged. 
This controller is only suitable for the following 12V/24V battery types: 
ordinary electrolyte lead-acid battery, 
maintenance-free lead-acid energy storage battery, deep cycle battery, gel battery 
warning! This controller is not intended for nickel-cadmium batteries, nickel-metal hydride batteries, lithium batteries, and other types of rechargeable or non-rechargeable batteries.

Installation and connection

Install the controller in the appropriate location and keep it as close as possible to the battery. The mounting surface must be solid and flat, dry and not easily ignited. The battery cable must be as short as possible and match the appropriate cable cross-section (eg 4mm2 20A current, 2m length). 
If the battery is operated within a large temperature range (summer/winter), be sure to install a temperature-controlled probe (if any) words). A temperature-compensated charging voltage extends battery life and increases available power. 
To ensure air circulation, keep a 10cm spacing around the controller. 
During the installation process, connect the components in the following order. 
1. Connect the positive and negative terminals of the battery to the positive and negative terminals of the controller. 
2. Connect the positive and negative poles of the solar module to the positive and negative terminals of the PV input of the controller. 
3. Connect the load to the positive and negative terminals of the controller's load output port. 
When disassembling, proceed in the reverse order. 
WARNING: Incorrect installation sequence can result in damage to the controller.
