Recommendations
• The controller can adjust the charging voltage by detecting the ambient
temperature, so that the controller is as close to the battery as possible.
• The system current density of the recommended cable is less than 3A/mm2.
• Try to use multiple strands of copper wire to connect firmly to the terminal.
Loose power connections and/or wire corrosion may cause resistance
connections, melt wire insulation, burn surrounding materials, and even cause a
fire.
• The battery should be fully charged every month. Otherwise the battery will be
destroyed.
Features of LCD graphic symbols
1. The default night display of the controller: When the controller detects that the
input voltage of the solar panel is less than the voltage of the sensor
identification point, this graphic symbol is on.
2. The default daytime display of the controller: When the controller detects that
the input voltage of the solar panel exceeds the voltage of the sensor
identification point, this graphic symbol is on.
3. Photovoltaic array parameter indication: When the solar panel data is displayed,
this graphic symbol is displayed. For example, the voltage of solar panels.
4. Battery parameter indication: When the battery parameter is displayed, this
graphic symbol is displayed. For example, the voltage of the battery, the
temperature of the battery.
5. Load parameter indication: When the load parameter is displayed, this graphic
symbol is displayed.
