The new product called DuoRacer MPPT charge controller will help solar systems to work better.
The DuoRacer MPPT charge controller exhibits remarkable priorities over conventional MPPT charge controllers that here, in this article, we will try to inform the customer about these features.
The EPEVER DuoRacer charge controllers, despite the XTRA series, are designed to charge two different batteries simultaneously.
These batteries, called BATT1 and BATT2, are used in the same solar system.
BATT1 supports different types of batteries, including Sealed, Gel, Flooded, LiFePO4 and Li-NiCoMn, which is suitable for recreational vehicles, motorhomes, boats, etc.
The device automatically recognises the system voltage of the starter battery (BATT2), and when the charging conditions are met, the charging process begins.
The energy utilisation of MPPT charge controllers is 20-30% more efficient than conventional PWM charge controllers.
The DuoRacer charge controller adopts the advanced MPPT control algorithm.
This algorithm is used to minimise the loss time in addition to the maximum power point loss rate and also leads to fast tracking of the maximum power point (MPP) of the PV array.
The outstanding feature of obtaining maximum power from the solar array in any condition distinguishes the EPEVER DuoRacer MPPT charge controller from other types of charge controllers.
EPEVER DuoRacer charge controllers features
In this section, we will present some of the outstanding features of the new EPEVER DuoRacer charge controller.
Maximum Power Point tracking technology with ultra-fast tracking speed and the tracking efficiency is guaranteed not less than 99.5%.
Advanced MPPT control algorithm to minimise MPP loss rate and loss time.
Wide range of MPP operating voltage to improve the utilization of PV module.
Automatic charge power control and charge current limiting function (BATT1).
High quality components and low failure rate from ST, TI and Infineon to ensure product lifetime.
Digital circuit control of the three-stage adaptive charging mode to improve the life of BATT1.
The BATT1 type can be configured via LED / LCD.
The product runs in low power mode when there is no manual operation for a long time and the charging conditions (PV <5V) are not met. Low power mode can significantly reduce the loss of the product at night.
100% charge and discharge in the ambient operating temperature range.
Selectable LED and LCD display units.
AES control signal for car cooler to avoid energy waste.
Standard Modbus protocol and RS485 communication port (5V / 200mA) for the customer to expand the application area.
In this section, the protection features of the DuoRacer charge controller will be discussed, these features will help to improve product life and are among the important priorities over conventional charge controllers:
PV over current and power limit function.
