Our controllers are designed for charging battery banks.  We offer two types of controllers; PWM (Pulse Width Modulated) and MPPT (Maximum Power Point Tracking)

PWM charge controller for dual battery bank 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 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.

The optional remote display provides all the information you need to track the performance of your solar panel.  It is particularly useful when optimizing panel tilt using our top-of-pole mounting system.  The display plugs into the Dual Bank Battery  Controller.

MPPT charge controller for charging a single battery bank
