MPPT DuoRacer Series Dual Output Marine Controllers

EP DuoRacer MPPT Controller
Picture
The DuoRacer marine series solar controllers are the first MPPT controllers designed with dual output. The DuoRacer controller can charge two battery banks simultaneously.  The bulk of solar power is used to charge the primary or main house battery bank (batt1) while a lesser amount of solar power is used to trickle charge the secondary battery bank (batt2) which is typically the start battery.  The battery banks do not have to be of the same battery type so the primary bank can be LiFePO4 batteries and the secondary bank can be AGM or lead acid.  DuoRacer controllers support Sealed, Gel, Flooded, AGM, LiFePO4 and Li-NiCoMn battery types.  

Max power from solar panels - DuoRacer controllers have rapid MPP (Maximum Power Point) calculation capability to achieve the maximum output from a solar array.  At 99.5% efficiency they are one of the most energy efficient controllers available which means they will convert the maximum amount of solar energy to battery charging power.


Max power to the battery bank - With the programmable three-stage charging mode based on a digital control circuit, the DuoRacer series controllers monitor the battery state of charge and feed the appropriate amount of power to effectively and safely charge the battery banks. This will enhance the life-cycle of batteries, significantly improve the system performance and provide electronic protection features.  Protection features include overcharging and over discharging protection and overheating protection. 

System Monitoring - DuoRacer controllers include a built in display meter providing the same information as the MT11 remote display meter which is an optional accessory.  The DuoRacer can be easily programmed from the built in display, the MT11 remote display meter, an optional Bluetooth smart phone app or a computer connected via an optional cable.  The Bluetooth option enables monitoring the solar system from a Smartphone or tablet.
Features:
•  Maximum Power Point Tracking (MPPT) technology with ultra-fast tracking speed and tracking efficiency of no less than 99.5% 
•  Dustproof and waterproof design with IP32★class
•  Automatic low power mode when no activity
•  Advanced MPPT control algorithm to minimize the maximum power point loss rate and loss time
•  High quality components, maximizing system performance, with maximum conversion efficiency of 98%
•  Accurate recognition and tracking of multiple-peaks maximum power point 
•  Automatic limitation of the charging power and current
•  Wide MPP operating voltage range
•  Compatible with lead-acid, AGM, sealed, lithium-ion and LiFePo4 batteries
•  Battery temperature compensation function
•  Real-time energy statistics function
•  Overheating power reduction function
•  RS-485 communication bus interface and Modbus communication protocol
•  Monitor and set the parameters via built in display, MT11 meter, mobile phone app or PC software 
•  Automatically detect 12 and 24 volt systems
•  Extensive electronic protection

Accessories

Optional Remote Display  - MT11

Remote display MT 50 for MPPT solar controllerMT11 Remote Display
The MT11 Remote Display is used to monitor the performance of the solar panels including volts, amps, watts and cumulative watts.  It also displays the state of charge of the battery bank and the controller status.  It is used to easily program the operating parameters of the DuoRacer controller.  

The display includes a 10 foot (3 meter) cable with RJ45 connectors that simply plug into the controller and the display.


​
Features 
•  Display all the operating data and system working status
•  Simple and convenient operation
•  Real-time alarm and failure information
•  Longer communication distance based on RS485
•  Diversified load control modes : Manual Control, Light ON/OFF, Light ON+ Timer, Time Control
•  Specify battery type: Gel, sealed, flooded and User(programable)
•  Set DuoRacer programmable parameters
•  Accumulate and display energy statistics



Optional Remote Temperature Sensor

Remote temperature sensor image
The optional remote temperature sensor constantly measures and  displays storage battery temperature so the controller can adjust charge rate appropriately. This is especially important when using temperature sensitive gel batteries.  This option could increase battery life by 100-200 charge/discharge cycles.

The sensor plugs into the Xtra-N Controller and is attached to the top of a battery in the battery bank with tape or adhesive.
