MPPT Solar Charge Controller 40A Tracer4215BN Schematic Diagram
SolarEpic 4215BN Solar Charge Controller 40A:
Built with advanced power tracking technology to optimize the working of your solar charger system. The controller features a smart tracking algorithm that maximizes the energy from the solar PV module(s) and charge the battery. It supports over four charging options: sealed, gel, flooded and user-defined. Battery parameters can be set using the attached MT50 remote meter.
MT50/MT52 Remote Meter:
Wide LED screen displays the real time operational data and the working status in digital, graphic and textual forms. Basically used for monitoring and setting the controller, it automatically identifies the type, model and relevant parameter data of solar controllers.
Battery Temperature Sensor and PC Communication Cable:
It is used to monitor each controller on the network using Solar Station PC software and update the firmware. Measures 3m and works great for Tracer BN/A series MPPT charge controller. The connectors are well made to secure the connection.

Add purchase two of these this one is working as it should The other one likes to bounce back into 12 volt mode even though it's in 48 volt configuration.

We installed our solar power system at our camp a couple weeks ago. The SolarEpic/Epever charge controller is controlling power from a 440 watt bifacial panel going into 3 100ah lifepo4 batteries.Not being familiar with all this gear, it took a while to understand what MPPT meant and what it does. Simply put, it is an algorithm built into the controller that converts excess voltage into amps which increases amperage to the batteries. Where as PWM controllers cut off the voltage at maximum allowable levels and any excess voltage is wasted energy. That's what make MPPT desirable. The unit does indeed boost available power, especially under less than ideal conditions. In addition to the bifacial panel, the controller manages to get very good current to the batteries.The controller is programmed with the included MT50 remote display/programmer. It come with standard setting for various lead/acid battery types. It's not particularly friendly for auto settings for lifepo4 batteries. However, it does provide a very flexible "User" setting option that can be tailored to suit any lifepo4 battery. It's a little confusing at first, but if you have the technical data for batteries and solar panel, the setting can be dialled in very accurately. This is a very popular controller and there's lots of Youtube info on how to use the SolarEpic/Epever charge controller. Do your homework first then it will be much easier to program the controller.

nice having the monitor to see what's going on with charging at different times of the day month or year, know exactly how much power I'm producing , casing is heavy duty

Knocked off a star because temperature sensor went bad in a few months. Purchased this controller in April based on reviews and came highly recommended by Will Prowse. Three months in the temperature sensor went bad. At 94° it said my battery temp was -1C (30°) and shut down my solar to protect the battery. I contacted the seller and they were quick to respond which was a plus. The problem though is that apparently they have no replacement parts. They messaged they would send a replacement temperature sensor but that it comes from the manufacturer and would take awhile. I don't know what awhile is in actual time and I'm hoping it's before cold weather but will update on seller follow through. The charge controller itself is solid and does its job well.UpdateNew sensor arrived. We're using this controller with 400watts of solar in series and a 300amp hour battery to keep our 12 volt compressor fridge going in triple digit heat. It does the job and it does it really well. Big thank you to the seller for follow through and getting us a new sensor. Added fifth star even though there was an issue because sometimes things just happen and the seller was on the ball and made it right. Would purchase again.

I have three of these. A total of 8 years of operation. They are robust and as efficient as any including a blue popular one that has "up to 98% efficiency" that in reality only occurs at one operating point and then only with 24 volt batteries and is rounded up in any event. The Epever manual provides efficiency curves for 12V and 24V battery charging. This is far more information than any other solar controller manual that I've looked at. They have more robust terminals, larger heat sinks (which never get more than slightly warm to the touch). Heavier than most but that's part of being robust. These are sold in 120 countries and are built for inhospitable environments. Yes, I'm very fussy about my solar controllers.There are ONLY two downsides to this Epever solar controller; both occur if you are using LiFePo4 "lithium" batteries. One is that you must enter your own LiFePo4 charging settings. The other is one LiFePo4 setting that is a critical one and is not identified or discussed in the otherwise extensive manual. This is the voltage the battery must drop to for the solar controller to enter its three stage charging regime each morning instead of going directly into float mode (wherein any needed charging is very slow). Since LiFePo4 batteries rest at 13.3V fully charged and don't let the voltage drop much, this setting has to be 13.4V or higher to ensure proper solar charging occurs each morning when the sun comes up. In RV use, one wants a full charge each day so as to be best prepared for inclement weather.

This is a good MPPT charger. I can set my own battery parameters using the MT50 monitor.Other off grid folks notice the same problem I used to have with my old chargers...a lot of times my old charger would go in float and shut my solar array off and I would be running things off my battery bank during sunlight hours!!! I have a large battery bank and have set absorb to 3 hours and would have set it for more hours because my batteries can be in absorbtion or boost charge for 12 hrs. I set my float charge up to 14.5 volts. I want my batteries charging as long as the panels can gather energy and I definitely do not want to be running off batteries before it is night time. I could not figure out what my earlier chargers were doing in float but they allowed my batteries to drain a little in afternoon and then kick back into charge mode when a preset low volt level was reached in float mode. This usually occurred right about the time the sun was setting so my batteries would not be at the maximum charge and surface charge as I headed to night time. Check your settings on your charger if you are off grid and your battery bank voltage at night. It took me a summer to figure out was going on and made me mad to find the sun was shining and I was running my home off the batteries instead of the panels!!! I love all my free daytime solar power..crank my freezer up full blast and charge up all my tools, phones, computers, run tools etc. After my batteries are full all the surplus electricity is free!! This Solar Epic has a 20 amp load outlet and shows the battery being charged and the load powered by your panels. Love the Solar Epic and have extra current and panels ( not over 130 volts) hooked to it so the charger is always getting max power to it. You can have more than 40 amps going into it but do not go over 130 volts. READ THE OWNERS MANUAL!UPDATE...unit is working great!!! The tracking seems to react quickly to passing clouds etc that some reviewers had complained was slow. I may buy another unit in the future.
