MPPT saulės energijos reguliatorius EPsolar 60VDC / 10A DuoRacer - 12 / 24V

MPPT charging controller DuoRacer DR1206N-DDS is designed to charge two batteries - on-board and starter (shown below as BATT1 and BATT2) in the solar system. This controller supports several types of main batteries (BATT1), including sealed, gel, flooded, LiFePO4 and Li-NiCoMn batteries, which are suitable for RVs, caravans, boats, etc. The device automatically detects the voltage of the starter battery system (BATT2) and when the conditions are met the battery charges.

The controller works as an inverter, which means that higher input voltages and lower currents can process at lower voltages / increase current with high efficiency. So we can use virtually any solar panel.

The DuoRacer solar controller is equipped with the latest MPPT (Maximum PowerPoint Tracking) technology - maximum power point monitoring with a sophisticated monitoring algorithm, where the solar module operates at the ideal voltage that the solar module can produce at the highest available power. Compared to a conventional PWM controller, MPPT technology increases charging efficiency by approx. 30%.

The maximum battery charging power of this model is 10A, which corresponds to a panel power of 130 Wp if you have a 12V battery, or 260 Wp if you have a 24V battery. If the panel gives a higher power, then the controller will only limit it to its nominal maximum power. The power of the PV panels must not exceed 1.5 times the nominal power of the controller - ie 190Wp resp. 390Wp!

You can connect solar panels in series, their no-load output voltage referred to as Voc must never exceed the no-load voltage value Voc 60V - exceeding this value will permanently damage the controller (here it is necessary to take into account that as the ambient temperature decreases the solar panel voltage and value The water specified in the solar panel parameters is at 25C). Therefore, we do not recommend that the value of the stated Voc exceeds 45V).

Main function:
- Maximum power point tracking technology with extremely fast tracking speed and tracking efficiency of more than 99.5%
- Advanced MPPT control algorithm to minimize speed loss and MPP time loss
- Wider MPP operating voltage range to improve PV module utilization
- Automatic charge control and charge current limitation function (BATT1)
- High quality and low failure rate of ST, TI and Infineon components to ensure product life
- Digital control of the adaptive three-stage charging mode circuit to increase BATT1 life.
- BATT1 type can be set via LED / LCD.
- If there is no charging for a long time and the PV array has a low voltage (PV <5V), the controller switches to low consumption mode.
- 100% charging and discharging in the operating temperature range.
- AES control signal for car refrigerator
- Standard Modbus protocol and RS485 communication port (5V / 200 mA).
