EPEVER 40A MPPT Solar Charge Controller Tracer AN Series fit
EPEVER 40A MPPT Solar Charge Controller Tracer AN Series fit for Lead-Acid and Lithium Batteries with 12V/24V DC Automatically Identifying System Voltage
Connect the system in the order of Battery→ Load→ PV array in accordance with Figure “Schematic Wiring Diagram” and disconnect the system in the reverse order.
Warm Tips:
- Battery must be connected firstly !!!Never connect the soalr panel array to the controller without/before a Battery.
- If an inverter is to be connected to the system, connect the inverter directly to the battery, not to the load side of the controller.
- While wiring the controller do not close the circuit breaker or fuse and make sure that the leads of “+” and “-” poles are connected correctly.
- A fuse which current is 1.25 to 2 times the rated current of the controller, must be installed on the battery side with a distance from the battery not greater than 150 mm.
- If the controller is to be used in an area with frequent lightning strikes or unattended area, it must be installed an external surge arrester.
It is very important to configure the system reasonably. For the recommended maximum power of PV array for this controller, please refer to the table below:

I have 4 epever mppt’s . one 60A two 40A and one 30A.
All have there own setting of solar panels, The 60A have two strings of 6 parallel. the 40A have each 4 panels (totall 800W) of 200W. And the 30A have 3 200W panels.
They are all 4 feeding in a 800A lithium battery bank. There are 2 4000W inverters on connected. and the supplies the whole house off grid.
I am really pleased with Epever, i had two other mades but was not to my satisfaction !!
I ordered, and MTTP unit. It arrived within a couple of days along with a message explaining how to install I found the company very highly professional and answered all questions promptly. Very good, highly recommended.
Quick delivery and good quality product. I had a query, just from being a solar Panel novice. I sent them a video of my installation and they solved it for me quickly. Would buy from them again.
I connected a string of solar panels to this device and it used the power from the solar panels to charge my battery bank. How cool is that. Unfortunately I don’t have a video of this happening, so the illiterates amongst you will just have to get someone that can read to draw you pictures. Priced a little on the high side, for what you get, but has proven to be reliable in preventing my battery bank bursting into flames.
Replaced a supposed mppt controller (was pwm) with this beauty and all my problems disappeared now got fully charged batteries. The batteries only supply water features in the garden but were constantly discharging with old controller this is no longer a problem wish I had just paid that bit more in the beginning .
Some people complain about the scrolling display didn’t find this a problem just press the enter button and the display lights up and you can move to the display you want that is if you cant be bothered waiting for it to scroll through. I must admit I did struggle initially with changing the load output setting but once I figured it out it was obvious maybe me just be being a bit dim. Overall impressive bit of kit.
I should have come straight to Amazon 🙂
The unit is as advertised and has been working perfectly since I fitted it..
Happy to recommend this produc
Also by using a piece of paper next to the screen to reflect the surrounding light, it is easier to read the poorly lit screen.
So far its seems to be working well at charging the batteries.
A well made and sturdy looking MPPT charge controller made from high grade plastic and aluminium that feels like it will last a long time. There’s plenty of surface area on the back for cooling, which gives me confidence in its ability to handle the electrical current generated on sunny days. The customer service I received was also very responsive, sincere and helpful.
Plenty of online guides for help setting up and epever customer service are very responsive
I originally wrote a one star review based on the failure rate of the MPPTs, but after several emails of the company’s customer service I came to the conclusion that said failures were caused by installer error (myself), rather than poor manufacture.
Because of said error, I cannot attest the function of the product (an I invite you to read other reviews in that regard) but I can confirm wholeheartedly that the company pays attention to the customer and tries solving any problem that might stop you from using the product. Which is in this time and age a rarity.
(I opened the unit in my possession and I can confirm that the electronics, heat management and manufacture are high quality).
I followed the instructions and it was easy to install. It appears to work well — although this is my one and only installation so I have nothing to compare it against — I do have a sophisticated battery monitor (that uses a 200am shunt) so I can cross check the readings on the Solar Charge Controller and they agree.
One thing that the controller manual does not make clear is what voltage is output on the “load terminals”, indeed the manual does not make it clear what the load terminal are for! As I wanted the solar system to change the batteries on my narrowboat I have ignored those “load” terminals. If I could I would remove the load monitoring from the display.
The reason I have given this a four star rating and not a five star is because the computer software installation is poor. I have a Microsoft Windows 10 laptop and I would expect all software for Microsoft machines to use the standard Windows 10 installer. Instead this software seems to use something that is probably compatible with Windows Vista. The software comes in a “.rar” file which is not compatible with the standard Windows 10 file explorer (I used 7-Zip to access the files although winzip will probably work as well). Once extracted there is not one installer but two. The first installs the drivers and the second installs the software. This is very old school. Normally such software would be web-based but with a simple installer that would check for the version of Widows that is being run and install the appropriate software from the website and it would include an uninstall option to clean up the computer if the software is no longer needed or proves to be buggy.
After some messing around I was able to install the software and it works, but I suspect that most amateurs who install this product, will not be able to get the PC software working, and will not understand the error messages they get about device drivers not working. It is a shame because with a modern Windows 10 installer this useful interface would be much more easily accessible.
The controller also works well with “EPEVER eLOG01 Record Accessory Adapter”, but I did come across one glitch. I disconnected the solar panels from the controller to install another solar panel. When I reconnected the solar panels to the controller it registered the reconnection on the display panel, but it failed to update the information into the adapter. I had to unplug the cable that connects the controller to the adaptor before the data started to flow from the controller into the adaptor.
So 5 out of five for the controller, but 3 out of five for the computer software.
