Our controller is designed specifically for charging two independent battery banks.

Charge controller for dual battery systems
Model EP Duo 12/24V 10A
Model EP Duo 12/24V 20A
Both models offer the following advanced features

Charging of two independent battery banks:
The owner can set charging priority between the two battery banks in steps of 10%. For instance, you can decide that 80% of the solar current should go to the house battery and 20% 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.

Remote display with charging data (option): 
• Remote 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.

Dimensions:
• 
Charge controller: 6" x 3 1/16" x 1 3/8" (155 x 77 x 35 mm). Weight 8.8 oz. (250 g) for 10A model, 10.6 oz. (300 g) for 20A model.
