.
LED off: PV voltage is lower than battery voltage or solar input
polarity is connected in wrong way, solar input would be cut off.
1. Illuminate green light: Battery is well-functioning and voltage of
battery falls within 12.5-13.6V;
2. Blink in green: Battery is fully charged and in float charging
mode, voltage of battery is 13.6-14.4V.
3. Illuminate orange light: Battery is weak. Voltage of battery falls
within 11.5-12.5V.
4. Illuminate red light: Battery is depleted. Voltage of battery is
below 11.5V.
Battery
1. Illuminate red: Polarity of battery is connected in wrong way, or
the battery voltage is below 7.5V
2. Blink in red:
●
Battery is over discharged. Battery can't be charged again.
●
Voltage of battery is higher than 14.4V or battery is broken.
Battery can’t be charged
●
If battery is charged with a large current (>10Amp) more than
3 second, controller will cut off input of battery and red LED
would blink for 3 minutes and then light off.
●
Over voltage of solar panel.
3. LED off: No abnormality is detected.
1. Illuminate white light: System provides power to load in proper
