EPEVER 40 Amp MPPT Solar Charge Controller for Negative Ground

This 40A MPPT solar charge controller, the EPEVER Tracer 4215BN, is designed to prolong the life of your battery. Its smart battery protection system shields your device from overcharging, overloading, overdischarging, overheating, and reverse polarity, while also providing efficient short-circuit protection.

The controller can handle up to a 520W solar panel on a 12V battery system or a 1040W solar panel on a 24V battery system, making it suitable for home, industrial, or commercial use. It is engineered for optimum and safe charging performance, with a MPPT tracking efficiency of over 99.5% and a maximum charge conversion efficiency of up to 98%.

The Tracer 4215BN offers several technical features: - Nominal system voltage: 12V, 24V - Rated charge current: 40A - Rated load current: 20A - Maximum PV open-circuit voltage: 150V / 138V - Maximum PV input power: 520W (12V battery) / 1040W (24V battery) - Recommended power input: 600W (12V battery) / 1200W (24V battery)

The controller also provides a range of charging parameters, including: - Boost charging voltage: 14.5V - Boost reconnect charging voltage: 13.2V - Charging limit voltage: 14.6V - Discharging limit voltage: 10.6V - Low voltage disconnect: 11.1V - Low voltage reconnect: 12.8V - Under-voltage warning: 12.0V - Under-voltage warning reconnect: 12.8V

Key product features include a 150V PV input allowing more panels to be connected in series, a negative grounding design for RVs, an aluminum case, and a solid build. The controller also offers multiple load work modes and a temperature compensation coefficient of 0.

Installation is straightforward, with the components connected to the charge controller in a specific sequence, and the battery always connected first to allow the controller to recognize the system voltage. The battery fuse should be installed as close to the battery as possible, within 150mm.

The Tracer-BN series is a negative ground controller, so any negative connection of solar, load, or battery can be earth-grounded as required.

There are three ways to set the MPPT charger: using a remote meter MT50, the EPEVER Android app via the EPEVER eBox (WiFi or Bluetooth), or the PC monitoring software "Solar Station Monitor" (using a USB to RS485 converter cable).
