Charging of two independent battery banks:

The owner can set charging priority between the two battery banks in steps of 10%. For example, you can decide that 90% of the solar current should go to the house battery and 10% to the start battery.  When one battery bank is full all the power is redirected to the other battery.

Battery optimized charging algorithms:

• Advanced PWM four stage algorithm with bulk, absorption, float and boost (equalization) charging.

• Charging voltages are optimized for the selected lead-acid battery type (liquid, sealed or gel).• Selectable PWM charging frequency (25, 50 or 100Hz)

• Temperature compensated charging using either a built-in temperature sensor or an optional remote sensor.

External display with charging data (option):

• External backlit LCD display can be mounted recessed or in a provided frame up to 10 m (33 ft) from the charge controller.

• Display shows charging voltage, actual current, max current and total amp-hours provided by the solar panels.

• Display shows current, minimum and maximum voltage of each battery bank as well as charge provided in amp-hours.

• Other information includes temperature, time, charge priority and frequency settings and troubleshooting information.
