EPEVER 40A MPPT Solar Charge Controller 12V/24V Auto Working Max. PV 150V Modular Design Solar Panels MPPT Regulator with LED&LCD Display Double USB Port for Lead-Acid and Lithium-ion Batteries

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.

1. Note: Connect the system in the order of battery -- load -- solar panel and disconnect the system in the reverse ordersolar panel -- load -- battery
2. Grounding: As the TRIRONN series is a common negative controller, the negative poles of the PV array, battery and load can be grounded together.
3. 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.
4. 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.
