Firstly: Controller Installation:
Mppt controller PV module components installed, after the external circuit construction safety engineering, in the following order to connect and secure operating system components.
- Prepare relevant tools and cable, suggest that choice the suitable cables, to insure that the current density is less than 2A / mm, this will help circuit to reduction voltage.
- Battery positive and negative securely connected to the positive and negative of controller(battery sign).
- Solar panelpositive and negative securely connected to the positive and negative of controller (solar panel sign).
- Loadpositive and negative securely connected to the positive and negative of controller (load sign)
(Disassembly: To prevent accidents, remove the solar modules connection first,then take the battery connection)
Secondly: Controller Interface Description and adjustment (press the up key to enter the interface converter)
Interface 1: The initial interface, surface display solar panel voltage; actual charging power; battery voltage; charging current.
Interface II: Under-voltage protection voltage setting
- Enter second interface, press the “ON” digit flashes, then press the up or down keys tomake digitincrease or decrease.
- After setting up the required value Press “OFF” to exit.
Interface III: Recovery discharge voltage settings
- Enter second interface, press the “ON” digit flashes, then press the up or down keys tomake digitincrease or decrease.
- After setting up the required value Press “OFF” to exit.
Interface Four: Close charging voltage setting
- Enter second interface, press the “ON” digit flashes, then press the up or down keys tomake digitincrease or decrease.
- After setting up the required value Press “OFF” to exit.
Interface fifth: float voltage settings (usually not set by factory setting)
- Enter second interface, press the “ON” digit flashes, then press the up or down keys tomake digitincrease or decrease.
- After setting up the required value Press “OFF” to exit.
Interface sixth: Controller internal temperature and battery temperature display
Interface seventh: display controller model and controller system voltage
