WIRING CONNECTIONS
1. Connect components to the charge controller in the sequence as shown above and pay
particular attention to the “+” and “-”.
Please don’t insert the fuse or turn on the breaker during the installation.
When disconnecting the system, the order will be reversed.
2. Power on the controller, check the LCD screen turns on. If the screen does not power up,
refer to page 9 TROUBLESHOOTING.
Always connect the battery first, in order to allow the controller to recognize the system
voltage.
3. The battery fuse should be installed as close to battery as possible. The suggested distance is
within 150mm.
4. The Smart Controller Range is a positive ground controller. Any positive connection of solar,
load or battery can be earth grounded as required.
NOTE: Please connect the inverter or other load that it has the large start current to
the battery rather than to the controller, if the inverter or other load is necessary.
