Fault behaviour
Operating the solar charge controller is dangerous in the following situations:
The solar charge controller does not appear to function at all.
The solar charge controller or connected cables are visibly damaged.
Emission of smoke or fluid penetration.
When parts are loose.
In these cases immediately remove the solar charge controller from the solar panels and battery.
Function
The solar system controller is designed to:
Monitor the state of charge of the battery;
Controls the charging process,
Control the connection/disconnection of loads,
Make sure solar system works at proper condition.
Manual load switch with automatic re-start.

Installation
Danger of explosion from sparking! Danger of electric shock!
The solar charge controller may only be connected to the local loads and the battery by trained
personnel and in accordance with the applicable regulations.
Follow the installation and operating instructions for all components of the PV system.
Ensure that no cables
are damaged.
Ensure that polarities of Solar panel/battery/load are connected in proper way.
