some may or may not contain a battery management system(BMS). Consult the lithium battery manufacturer before
charging. Some lithium-ion battery may be unstable and unsuitable for charging.
4.1 Connecting to Solar Panel and Battery.
Do not connect the charge controller until all other connections are made. Identify the correct polarity of the solar panel and
battery terminals. The male SAE connector is positive and female SAE connector is negative, the positive battery terminal is typically
marked by these letters or symbol (POS,P,+). The negative battery terminal is typically marked by these letters or symbol (NEG,N,-).
Do not make any connections to the carburetor, fuel lines, or thin, sheet metal parts.
1) Expose the solar panel to full sun without shade.
2) Connect solar panel to charge controller, the LED screen will illuminate and display selected battery mode voltage.
2-1) If the LED screen and indicators don’t illuminate, the polarity of your solar panel probably doesn’t match charge controller.
(Please note: This MPPT charge controller has standard polarity, you need a polarity apdater/reverser if your solar panel polarity
doesn’t match the charge controller.)
3) Press mode button to toggle to the appropriate battery types, the mode LED will illuminate the selected charge mode.
4) Connect the charge controller to battery terminals, Wait 5-10s, the charge controller will enter charging mode once it recognizes
the battery. The SOC,battery voltage, charge current will illuminate indicating the charging process has started.
