NOTE
If you want 12V LI charging, then select the RIGHT ARROW again to move to LI Boost
Charging Voltage. If you want a 24V LI charging, then you select UP or DOWN ARROW
to move from 12V to 24V LI Charging. Once you confirm your LI Charging (12V or 24V)
press RIGHT ARROW to move to LI Boost Charging Voltage.
Press UP or DOWN ARROW to change the Boost Voltage. The default setting is 14.4V
and the user can set it in the range 12.0~16.0V, in .2 increments. Once done, hold RIGHT
ARROW to confirm the selection.
Once LI is flashing, select RIGHT
ARROW again and a 12V will flash
In the screen showing the battery voltage, hold down RIGHT ARROW for approximately
3-5 seconds before the screen flashes the current battery type. Once flashing, use the
UP or DOWN ARROW to highlight LI
3. Select Lithium Battery Voltage and Charge Voltage

The above settings are ONLY available for LI setting
MPPT Technology
Therefore, assuming 100% efficiency:
Power In = Power Out
Volts In * Amps In = Volts out * Amps out
The MPPT Charge Controller utilizes Maximum Power Point Tracking technology to extract
maximum power from the solar module(s). The tracking algorithm is fully automatic and
does not require user adjustment. MPPT technology will track the array’smaximum power
point voltage (Vmp) as it varies with weather conditions, ensuring that the maximum power is
harvested from the array throughout the course of the day.
In many cases, the MPPT charge controller will “boost” up the current in the solar system. The
current does not come out of thin air. Instead, the power generated in the solar panels is the
same power that is transmitted into the battery bank. Power is the product of Voltage (V) x
Amperage (A).
