DC-DC CHARGER GUIDE:
Understanding Solar, Alternator & Charging Lights
Alternator LED Battery Status
Alternator LED Battery Status Within Ignition Wire Connected
Solar LED Status
NOTE:
• Alternator has priority over solar therefore, if both solar and the alternator are
connected, only alternator LED is Solid and the alternator is charging.
• 30 second delay between the cut-in voltage being reached and charging beginning
and a 60 second delay before disconnecting when under cut-out voltage.
Voltage 12V Voltage 24V LED Status
0-8.9 Volts 12-17.9 Volts OFF
Under operating
voltage
9-12.6 Volts 18-25.2 Volts Flash 1 sec on 5 sec o Under cut-out voltage
12.7-13.1 Volts 25.3-26.3 Volts Flash 1 sec on 1 sec o Under cut-in voltage
13.2 Volts 26.4 Volts Solid On
Cut-in voltage reached
charging will start after
30 sec delay
Voltage 12V Voltage 24V LED Status
0-8.9 Volts 12-17.9 Volts OFF
Under operating
voltage
9-11.6 Volts 18-23.2 Volts Flash 1 sec on 5 sec o Under cut-out voltage
11.7-12.1 Volts 23.3-24.3 Volts Flash 1 sec on 1 sec o Under cut-in voltage
12.2 Volts 24.4 Volts Solid On
Cut-in voltage reached
charging will start after
30 sec delay
Solar Voltage LED Status
0-8.9 Volts OFF Under cut-in voltage
Unregulated 9-23V DC Solid ON
Cut-in voltage reached charging will
begin after 10 sec delay
(please note alternator has priority over solar)
