- Appreciate you for choosing MPPT solar charge controller, Tracer-BN series. Based on common negative design and advanced MPPT control algorithm, with die-cast aluminum design for heat dissipation, products in this series are artistic, economical and practical.
- With MPPT control algorithm, in any situation, products of this series can fast and accurately track out the best maximum power point (MPP) of photovoltaic array, in order to obtain the maximum solar energy in time, which remarkably improves energy efficiency.
- With Modbus communication protocol interface, it is convenient for customers to expand applications and monitor in various fields like telecommunication base station, household system, caravan system, street lighting system, wilderness monitoring system, etc.
- All-round electronic fault self-test function and enhanced electronic protection function could furthest avoid damages on system components resulting from installation errors or system failures.
- 12/24VDC automatically identifying system voltage or user-defined working voltage.
- LED indicators showing system status, simple and clear.
- Support 4 charging options: Sealed, Gel, Flooded and User.
- Advanced Maximum Power Point Tracking (MPPT) technology, with efficiency no less than 99.5%.
- With RS-485 communication bus interface and Modbus communication protocol, it is available to meet various communication requirements in different situations.
- Available for PC monitoring and external display unit connecting like MT50 and so on, realizing real-time data checking and parameters setting.
- Support software upgrade.
Feature:
- High quality components, perfecting system performance, with maximum conversion efficiency of 98%.
- Ultra-fast tracking speed and tracking efficiency.
- Accurately recognizing and tracking of multiple power points.
- Reliable automatic limit function of maximum PV input power, ensuring no overload under any circumstance.
- Wide MPP operating voltage range.
- Die-cast aluminum design, ensuring excellent heat dissipation characteristic.
- Multiple load control modes: manual control, light ON/OFF, light On+Timer and time control.
- Battery temperature compensation function.
- Real-time energy statistics function.
- he controller connection sequence is Battery--Load--Solar Panel, and discounect the system in the reverse order Solar Panel--Load--Battery
- The Tracer-BN series is a negative ground controller. Any negative connection of solar, load or battery can be earth grounded as required.
- Notice：
1）Unplug the RTS, the temperature of battery will be set to a fixed value 25 ºC.
2）Please connect the inverter to the battery rather than to the controller, if the inverter is necessary.
3）The RS-485 port and RTS port is not SELV circuit, it must have isolation between the port and the place where the end user can access directly.
Four methods to configure the controller:
- Remote meter, MT50 (Use standard twisted net cable, model:CC-RS485-RS485-200U-MT).
- Super parameter programmer, SPP-02(Use standard twisted net cable, model:CC-RS485-RS485-200U). One-key easily configure and apply to batch setting.
- PC monitoring setting software ―Solar Station Monitor‖（Use USB to RS485 converter cable with model: CC-USB-RS485-150U.
- Mobile APP (Use USB to RS485 converter cable: CC-USB-RS485-150U and Micro 5PIN OTG cable)

This is my second Epever Tracer4215BN 40A MPPT solar charge controller! These are extremely robust, high quality solar MPPT controllers which were designed to last a long time!If you are undecided about PWM vs MPPT, you should only consider MPPT if you need/want every possible watt of energy from your panels. The MAJOR advantage of MPPT over PWM is the ability to connect your panels in series, increasing the total voltage, thereby reducing the current in the wires back to your charge controller. Big deal? Well, YES! You see, as current increases, so do the heat/resistive losses in a wire and if you use a modified 100' 14ga extension cord as I do, you can lose a surprisingly large amount of solar energy to your wires. You can avoid this by simply connecting multiple panels in series (e.g. 4 x 100W panels at 22V) to produce around 88v which at 400W (theoretical) would require only 4.5A of current. The same 400W in parallel would push 18A through your extension wire, causing it to heat up significantly, dropping the total power delivered at your battery.The MT-50 is a must-have accessory so be sure to pick one up with this unit!

I have been building solar for friends and family, experimenting with different products for 4 years now, I have a background in electrical engineering, I first saw a review from two YouTubers and got one because I really trusted those two YTs, it worked out after months of testing for me in my situation I have 12 huge AGM Telco battery setup and the EPever 40/150 is now what I recommend also, service and support is right there fast if you need them, next I will play with larger Inverters and sooner or later I am going to have to start a YT channel to pass on all this information :)Me Bob@grandassets

The controller worked for about a month - now it sporadically charges the battery from the pv unit regardless of the solar intensity.I have used this model for the last 4 years and purchased a new model - big mistake.

Unlike most controllers which are light plastic, this seems nice and heavy like a proper controller should. Shipping was fast. Very happy.

They reached out to me and tried to assist without success. The controller did not work. They listened and will replace. I have updated to 5 stars for customer satisfaction.

I have used this charge controller made by the same china manufacturer for Renology, It has the exact same part numbers, They are NOT compatable and will throw you off. No where does the instructions tell you this.

Epever charge controllers are great. I have several of them and this one is as good as the rest. Easy to use, and very dependable. Plus iSunergy is a great vendor. Excellent communication and they shipped this unit really quickly.

The EPEVER 40A MPPT Solar Charge Controller is well engineered and built. It was appreciated that the vendor sent an email containing a PDF that contained an updated user manual. I connected the unit to my solar array and AGM battery bank and it has performed flawlessly. Highly recommended.

As recommended by Will Prowse from DIY Solar Power, the Epever 4215BN worked exactly as he said it would, easy to set up, configure, and worked on the first try. It started producing power to the batteries immediately. The unit was delivered extremely fast from China in only a couple of weeks, unlike ordering from Aliexpress which takes months. Extremely satisfied with the purchase.
