EPEVER TRACER8420AN solar MPPT controller 12/24/36/48V, Tracer AN 80A, input 200V

EPEVER TRACER8420AN

The powerful MPPT solar controller 8420AN provides a reliable solution for larger systems with panel voltages up to 200 V and a max. charging current of 80 A. Battery 12/24/36/48 V , PV max. 1000/2000/3000/4000Wp.

MPPT solar controller EPEVER Tracer 8420AN - a new generation of powerful solar controllers brings high quality and maximum equipment for PV systems. The Tracer AN series is characterized by high charging power , so it is suitable for larger island and hybrid systems.

A multifunctional display is integrated directly into the MPPT controller for easy system monitoring and possible setting of operating parameters, including control LEDs.

Function

The controller works as an inverter, which means that it can process a higher input voltage and lower current into a lower voltage and higher current, with high efficiency. So we can use practically any solar panel. The controller is compatible with lead and lithium-ion batteries.

Technology

Tracer AN series controller based on multiphase synchronous rectification (MSRT) technology and advanced MPPT control algorithm, with dual-core processor architecture and common minus pole. MSRT can guarantee very high conversion efficiency at any charging power, which obviously improves the energy efficiency of the solar system.

The advanced MPPT control algorithm minimizes power loss and downtime, ensures tracking efficiency as well as high conversion efficiency at high or low power, so in any situation, Tracer AN products can quickly track the maximum operating voltage of the PV array to extract maximum energy from the panel.

Maximum power of solar panels in Wp

The maximum charging power to the battery of this model is 80 A, which corresponds to a panel power of 1000 Wp if you have a 12 V battery, 2000 Wp if you have a 24 V battery, or 4000 Wp if you have a 48 V battery. In case the panel delivers higher power, the controller will only limit it to its nominal max. power. However, the power of the PV panels must not be higher than 1.5 times the nominal power of the controller, otherwise the controller may be permanently damaged!

Maximum input voltage of solar panels

You can connect solar panels in series, but their total output voltage at no load, referred to as V _oc (not to be confused with the voltage of the panel under load referred to as V _mpp ), must never exceed the value of the voltage at no load V _oc 200 V - exceeding this value will permanently damage the controller. It is necessary to take into account that the voltage of the solar panel increases with decreasing ambient temperature and the value of V _oc specified in the solar panel parameters is the value for 25 °C. We therefore do not recommend that the value of the specified V _oc exceed 180 V at 25 °C (voltage in the load V _mpp maximum 144 V)!

Monitoring and settings

The controller parameters (mainly the type of battery used) are set using the built-in LCD or the external MT50 display (not included with the controller). There are three basic types of batteries available: hermetically sealedboiled, gel, flooded. The fourth option is a user-adjustable battery (here it is possible to set any parameters).

Load relays or automatic generator control make it easy to create a hybrid power system. Comprehensive electronic protections, including overcharge protection, overdischarge protection and PV reverse polarity protection, effectively ensure the safer and more reliable operation of the solar system for a longer period of time. Isolated RS485 interface with standard MODBUS communication protocol and 5V power supply makes it easy for consumers to expand the device, supports up to 8 controllers in series to expand the system, and meets various monitoring requirements, so it can be used in various applications such as solar RV, home systems, field monitoring, etc.
