EPEVER 30A MPPT Solar Charge Controller 12V/24V Auto, 100V Max PV Input, LED/LCD Display with Dual USB Ports - Perfect for Solar Home Systems, RV, Boats & Off-Grid Power

The EPEVER TRIRON N series controllers are modular-designed products based on six MPPT solar controller models. The main unit(Power Module)(TRIRON-N) is a solar controller which can be integrated with different display and interface modules to meet a variety of functional requirements. The TRIRON N series controllers can automatically identify and load the drivers of various modules. With the advanced MPPT control algorithm, TRIRON N series controllers can minimize the maximum power point loss rate and loss time, quickly track the maximum power point of the PV array and obtain the maximum energy from solar modules under any conditions; and can increase the ratio of energy utilization in the solar system by 20%-30% compared with a PWM charging method. The TRIRON N series controllers can automatically identify and load the drivers of various modules. This modular solar controller can be widely used for different applications, e.g., communication base stations, household systems, street lighting systems and field monitoring, etc. Automatic limitation of the charging power and currentHave compensation real-time energy statistics functionSupports multiple types of lead-acid batteries and lithium-ion batteriesLCD and LED to display operating data and status of the systemWith the adaptive three-stage charging mode based on a digital control circuit, TRIRON N series controllers can effectively prolong the lifecycle of batteries, significantly improve the system performance and support all-around electronic protection functions, including overcharging and over-discharging protection Advanced MPPT technology, with efficiency no less than 99.5%. The TRIRON N series controllers can automatically identify and load the drivers of various modules.Provide 5VDC power through the dual USB output interface to charge electronic devicesMaster and slave RS485 communication modules design, reading the load or inverter operating data DB1: LED : PV & battery working status Button: When the working mode is Manual Control, the load is ON/OFF via the button.DS1: LED : PV & load working status. Buttons: View or set the parameters. LCD：PV display: voltage/current /generated energy/Battery display voltage/current/temperature. Load: Display current/load working mode when the controller communicates with the PC or APP. Display voltage/current/ power consumption when the controller communicates with the inverter.DS2: LED: PV & battery & load working status. Buttons LCD Load the same as DS1DCV: No indicator or display UCS: USB COM Slave.RCM: Relay COM Master. RCS: Relay COM Slave.USB1: Double USBCCV: No interface Note: Connect the system in the order of battery -- load -- solar panel and disconnect the system in the reverse ordersolar panel -- load -- batteryGrounding: As the TRIRONN series is a common negative controller, the negative poles of the PV array, battery and load can be grounded together.NOTE: The controller can also be used in a common positive system. In this case, the negative poles of the controller, PV and load can’t be grounded together, but only one of them can be grounded.If the remote temperature sensor is not connected to the controller, the default setting for battery charging or discharging temperature is 25 °C without temperature compensation.
