The powerful MPPT solar controller 10420AN provides a reliable solution for larger systems with a panel voltage of up to 200 V and a max. charging current of 100 A. Battery 12/24/48V, PV max. 1250/2500/5000Wp.
MPPT solar controller EPEVER Tracer 8420AN brings high quality and maximum equipment for PV systems. The Tracer AN series is characterized by high charging performance, making it suitable for larger island and hybrid systems.
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.

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

Technology:
- controller from the Tracer AN series 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 advanced MPPT control algorithm minimizes power loss and dead time, ensures tracking efficiency as well as high conversion efficiency at high or low power, so that in any situation, Tracer AN products can quickly track the maximum operating voltage of the PV system to extract maximum energy from the panel.

Maximum power of solar panels in Wp:
- the maximum charging power for the battery of this model is 80A, which corresponds to a panel power of 1250 Wp if you have a 12V battery, 2500 Wp if you have a 24V battery, or 5000Wp if you have a 48V battery. If the panel delivers higher power, the controller will only limit it to its nominal maximum power. However, the power of the PV panels must not be higher than 1.5 times the nominal power of the regulator, otherwise the regulator may be permanently damaged!

Maximum input voltage of solar panels:
- you can connect solar panels in series, their output total no-load voltage, referred to as Voc (be careful not to confuse it with the voltage of the panel under load, referred to as Vmpp), however, must never exceed the no-load voltage Voc 200V – exceeding this value will permanently damage the regulator. Here it is necessary to take into account that the voltage of the solar panel increases as the ambient temperature decreases, and the Voc value given in the parameters of the solar panel is the value for 25℃. We therefore do not recommend that the value of the stated Voc exceed 180V at 25℃ (load voltage Vmpp maximum 144V)! You can find the maximum allowed number of PV panels connected in series for individual types according to the 12/24/48V battery in the manual.

Monitoring and settings:
- the setting of the controller parameters (this is mainly the type of battery used) is done using the built-in LCD or the external MT50 display - it is not part of the controller. There are three basic types of batteries: hermetically sealed, gel, flooded. The fourth option is a user-adjustable battery - here you can set any parameters.
- parameter settings and monitoring can also be performed on your PC, you will only need an EPsolar USB communication cable and software, which you can download for free on the USB cable card. It can also be monitored and set using a mobile phone or tablet. For this you will need the bluetooth module BLE-01.

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