Dual battery DR2210N-DDB MPPT Solar Controller 20A 12v / 24v Dual battery output
The DuoRacer MPPT charge controller is designed to charge two batteries (shown as BATT1 and BATT2 below) at the same time in a solar system. This controller supports multi-life battery types (BATT1), including Sealed, Gel, Flooded, LiFePO4 and Li-NiCoMn, which are suitable for RVs, RVs, Boats, etc.
The device automatically recognizes the starter battery system voltage (BATT2) and slowly charges the battery when the conditions are met. The controller adopts the advanced MPPT control algorithm, which will minimize the maximum power point loss rate and loss time, also quickly track the maximum power point (MPP) of the photovoltaic array, and get the maximum power from the solar array in any condition.
The energy utilization in the MPPT solar system increases by 20-30% compared to the PWM charging method. When there is no manual operation for a long time and the charging conditions cannot be reached, the controller will switch to low-power mode, reducing the loss and waste of battery power to improve the life of the product.
System parameters are displayed and configured via LED / LCD or remote meter MT11 (accessory). The AES control signal of the car refrigerator is built into the controller, which will supply the surplus solar energy to the refrigerator to avoid wasting energy. The controller comes with an IP33 protection level,
which is resistant to water and dust. Multiple protection functions, including battery overcharge protection, over discharge protection and reverse connection protection of photovoltaic and battery, effectively ensuring the safety, stability and service life of the solar system. the controller will switch to low power mode, reducing the loss and waste of battery power to improve the life of the product.

What solar controller do I need according to the type of solar panel?
Normal regulator (PWM): Whether you have 12V solar panels to use in an isolated (or autonomous) 12V solar installation, or if you have 24V solar panels and 72 cells to use in a 24V installation, you must use a normal regulator (PWM type). Which is the most economical and suitable for this type of solar panel.
Maximizing regulator (MPPT): If you have 24V solar panels and 60 cells (power plates greater than 200W), to be used in an isolated 24V solar installation, you must use an MPPT maximizing regulator. Necessary to amplify the voltage of these solar panels, so that when it reaches the batteries it is high and the energy is well stored. The MPPT regulator is more expensive but it is necessary with this type of plates. Which without the use of MPPT, the useful life of the batteries would be damaged since they could not be equalized and they would sulfate in a few months.
