EPEVER TRACER6420AN Solar MPPT Controller 12 24 36 48V TracerAN 60A Input 200V

EPEVER TRACER6420AN

The high-performance MPPT controller is used to control the flow of energy from the solar panel or power supply to the batteries and the appliance. It works with 12/24/36 and 48 V systems and with currents up to 60 A. The maximum input voltage is up to 200 V.

The highest series of TracerAN solar controllers is a new generation that follows on from the TracerA series. Improves the MPPT algorithm and, thanks to the support of the 200V input voltage, allows the connection of a higher number of solar panels in series. This increases the overall efficiency of the solar system. The main advantage is the use of the state-of-the-art MPPT (Maximum Power Point Tracking) technology, which increases the efficiency of the entire system by 30% or more. MPPT technology ensures the maximum use of the energy supplied from the PV panel by selecting the consumption at the working point with the maximum supplied power. This point is continuously monitored and maintained. This compensates for all effects of temperature, different lighting intensities, etc.

This solar controller is suitable for a wide range of island applications such as family and apartment buildings. A multifunctional display is integrated directly into the MPPT controller for easy monitoring of the system and possible setting of operating parameters incl. control LEDs. The regulator from the Tracer AN series is based on multi-phase synchronous rectification technology (MSRT) and advanced MPPT control algorithm, with dual-core processor architecture and common minus pole. MSRT can guarantee a very high conversion efficiency at any charging power, which clearly improves the energy efficiency of the solar system.

The maximum charging power to the battery of this model is 60A, which corresponds to a panel power of 750 Wp for a 12V battery, 1500 Wp for a 24V battery or 3000 Wp for a 48V battery, which we recommend with this controller. If the panel gives a higher output, then the regulator will only limit it to its maximum. However, the output of the PV panels should not be higher than 1.5 times the nominal output of the regulator!

The open-circuit output voltage referred to as Voc must never exceed the value of 200 V - exceeding this value will permanently damage the regulator (take into account that the solar panel voltage increases as the ambient temperature decreases and the Voc value given in the solar panel parameters is at 25°C). We do not recommend that the stated Voc value exceed 180V.

The controller parameters are set using the built-in LCD or external MT50 display, or via the communication cable to the PC, see below.

Quick installation

1. We connect the battery to the solar regulator. We install a suitably sized DC fuse on the plus wire as close as possible to the battery pole
2. Connect the solar panel

In this model, appliances are connected directly to the battery.
