EPEver Tracer AN MPPT Solar Charge Controller Review - 12v Solar Shed

I'm taking a look at the new Tracer AN Solar Charge Controller from EPEver. I compare it to the Tracer A series which I've been using for a couple of years and find some nice improvements, and a little issue.

Thank you for that straightforward practical example of the MPPT conversion happening in real-time..

[@daveforbes4269]

Always wait for your solar reviews I purchased my A series after watching your original review and was very happy with it have just swapped to their new magic series 40A

[@SylvanSecrets]

Thank you. I'm considering this controller and this was a great help.

[@AubsUK]

Thanks for your videos, I've watched almost all of them, some multiple times! - Really appreciate your knowledge. Just (29 March 2022) bought the Tracer1206AN, it comes with a user manual that is V2.4, the one on their website shows V1.0. I've asked them for an updated version. Looking at the v2.4 manual, shows that it supports Sealed, Gel, Flooded, LiFePO4 (4S/8S) and Li(NiCoMn)O2 (3S/6S/7S). There's 9 battery choices for the 8 above (Sealed/Gel/Flood/LFP-4S/LFP-8S/LNCM-3S/LNCM-6S/LNCM-7S) and 1 for User. It has a table for each of the LFP and LNCM batteries, along with User, so it looks like newer revisions do properly support Lithium. If I get a copy of the manual, I'll add a link here. Otherwise, if anyone wants anything from the manual, ask and I'll do my best. For reference, the values for Li(NiCoMn)O2 7S are below, voltage in brackets taken from @Adam Welch 's "Update on the Solar Charged 18650 Blocks & the diyBMS - 12v Solar Shed" video at kzbin.info/www/bejne/g5TLd2uZaZqch9k (1 minute 48 seconds): Over voltage disconnect voltage 29.8 V (29.75) Charging limit voltage 29.4 V (29.25) Over voltage reconnect voltage 29.1 V (29.20) Equalize charging voltage 29.1 V (29.10) Boost charging voltage 29.1 V (28.70) Float charging voltage 28.4 V (28.00) Boost reconnect charging voltage 28.2 V (27.50) Low voltage reconnect voltage 24.5 V (23.00) Under voltage warning reconnect voltage 28.4 V (24.00) Under voltage warning voltage 24.5 V (23.00) Low voltage disconnect voltage 21.7 V (22.40) Discharging limit voltage 21.7 V (21.00)

[@djbare9]

I've been using an AN series since this video, mine is 10 amp, it's only requirement was for security, mainly a camera with access point wifi connection, my panels are situated in a bad location, during winter they will never see the sun due to buildings in the way, however there is just enough light to keep the batteries topped and the camera streaming thanks to the efficiency of this controller, thank you for the video!

[@mikestone9129]

Excellent review.

[@viocaia]

Nice done Adam!

[@Greolt]

I just bought a Tracer 3210AN. I has only one inductor, not two. Really appreciate your reviews.

[@randomthingch1970]

So excites building this off grid room for my room end of next year Hopefully....

[@ronjenkins4257]

Thanks for explaining the difference between the "A" and the "AN" models. I had an older "A" and got a newer "AN" and didn't know what the difference was. Now that I know, the next step is figuring out what it **means**.

[@SantaClaw]

I have the 30a version of the Tracer A at my cabin, with the MT50, I'm very happy with it.

[@AdamWelchUK]

I’m a happy tracer A user too.

[@cricketol]

Thanks you for the review

[@MrBrymstond]

Great review.

[@AdamWelchUK]

Cheers MrB

[@jarchdm]

Thx for the review i bought the tracer a 30a on your recommendation and have not regretted it for a minute ! my 7s 6p system is running well and i have connected the capacity controller to my home automation system so that it balances the batteries every day at 9 in the morning.

[@AdamWelchUK]

Excellent. Glad it’s working well for you and that integration sound interesting. I’d like to see that. Cheers

[@jarchdm]

ill try to put something together video vise

[@cgwworldministries83]

Thank you for this video

[@VenturiLife]

Good info. Thanks. The ones I can find go up to size a pretty small system per unit at 40A / 30A / 20A / 10A. So max size is probably around 700W mono panel total max at around 23% efficiency. So to be safe maybe 4 x 160W panels = 640W system. I was thinking of splitting the battery banks / systems anyway for redundancy, and have them run different loads on different circuits. So 2 x 40A units is around $229 USD for these units and a 1280W system split into two. Being a true MPPT charge controller is really good at that price, and mono panels are pretty cheap these days.

[@davidhopkins]

Thank you for all your videos on the Tracer series. I recently upgraded from a PWM to a Tracer. I am interested and very confused at comparing the two chargers. The Tracer tells me how many amps are coming in from the panels and going out to the battery. The increase, as a percentage, varies dramatically. I seem to get the most impressive increase at lower current. For instance 1.5 amps into the EPever gives 2.1 amps to the battery, or 40% gain. But with more sun I might see 5 amps into the charger and 6 amps to my batteries, or 20% gain. Why isn't the percentage gain more consistent? What influences how much of a gain the MPPT charger can deliver?

[@mcombsemail]

The 30amp model has a single inductor as well. The 40amp model has two inductors and I think they are the same size as the 30amp which probably explains the a higher price per watt than the 30amp. I like the new AN screen design not being soldered right on the mainboard. I personally have owned the 30amp and 40amp A series but have recently upgraded to the BN series because of the superior cooling.

[@RodneyWhittle007]

First of all, thank you for your videos, I've learned a lot. My question, I want to also setup in my garage with the EPEver charger and a 12 volt lithium battery. I've purchased the temp sensor. Can I program the controller to not charge the battery with the garage temperature is below freezing so that I can protect my battery?

[@pingchongwong7942]

Hi I just wonder how the load timer 1 and 2 works. Can u pls do video on this. Thankyou

[@TheYankmchain]

Hey chap! LOVE this vid. I'm considering the Tracer 8420AN. What FUSE TYPE/STYLE do you use between your EPEVER and your battery?

[@edyoung6573]

I picked this model up (30amp) for my teeny solar setup on my old Lance Truck Camper with one 12V Deep Cycle battery. Not even sure what solar panel is on the roof lol, But it still works. Picked up the the MT50 monitor also. Shows 19.9 Volts and 0.2A coming from panel.

[@vincedunnell7292]

Very good video keep it up

[@codingfun63]

just bought one today after using an old plasmatronics pl20 ,should be a great replacement .

[@stephenlee5882]

I like your videos, great job! Have you ever reviewed the Juntek VAT#### meters as a battery monitor?

[@cockney1776]

Hi Adam great videos I been and got a epever tracer an and while I was waiting I built the WiFi adapter as per Colin hicky post then watch ur review here to find out it struggles to connect could u tell me if any of the WiFi modules u tested work need to monitor it while my caravan is in storage( over the internet) I’m using a portable network in the van Thanks Lee

[@RWBHere]

Time to measure the RF interference that those things cause, Adam! If the box is plastic, and those wires to the inductor, and the inductor itself, are not screened, then the whole unit becomes a problem. OfCom would take a dim view of it. Apart from that major concern, it's a nice piece of kit, with some welcome improvements in this model. Thanks.

[@timstopics]

Very helpful videos. Wondering if you saw any issue in an RV application running the RV's stock 12V converter/charger output to the controller input ? I'd like to have more control over the charging profile of the RV battery which the stock converter/charger doesn't allow like the epever. Guess my thoughts are voltage is voltage whether its from a solar cell or other source ? Thanks !

[@CrilleX86e]

How do I reset the KWh meter on this device? Do you know? Please make a film.

[@Chickey]

Good review as ever, did the new controller come with any documentation or link to updated docs which might describe the pin out of the accessory connector. You could maybe get your scope or a logic analyzer on it to see which pins are now used for the output as it sounds like they've switch things around or a baud rate change maybe and the same pins?

[@AdamWelchUK]

The pin out is the same as stated in the manual (although when you click the manual link online for the AN it is the A series manual you get). I think the baud rate is a good shout - my scope doesn’t do logic, but the timings might tell me. Otherwise I can try some different settings on the usb cable and see what works and what doesn’t. Thanks Colin.

[@Drewcoull]

Hello Adam and thank you for your excellent reviews. Been following your content and appreciate the time, effort and knowledge you are extending to newbies like me in the solar world. I've just purchased an Epever AN controller and 100w panel to connect into an existing leisure battery in a campervan that is currently charged by alternator and 240v hook up charger. Would you know if diode protection for tbe EPever controller would be required to prevent current from the other charge devices damaging the Epever?

[@AdamWelchUK]

Glad to be of help. No you won’t need any protection on the charge controller. It can cope with being connected along side other chargers.

[@2012planetxcom]

Hello great vids thank you ... Question , I have a 10 amp version using 4mm cable , if I put 200 watt of panel on and its input goes just over 10 amps sometimes ( I live in the UK) what would happen. Thank u in advance

[@cleanadrainltd1246]

I’m replacing an cs-evolution charger with an epever but my current charger has an output for the vehicle battery and the epever does not. Where do I put them wires. Thanks in advance.

Hiya my Tracer AN has stopped working completely, is there anything I should check, internal fuses etc.. thanks in advance

[@randyscc]

I talked to an EE at EPsolar who said an older style mt50, made before October of 2017 will not sync with the new AN model charge controllers. If you look at the back side of the MT50 there is a date code that tells the build date

[@ekpemeisong1331]

Adam what causes battery boiling?

[@sanctuarylifestyle]

Hello Adam, great content, been watching for a while now, I’ve got an Epever tracer with remote ebox internet access aswell as an mt50 but struggling to set my 5 x lead acid battery’s 70ah each, any advice would be great,

[@aaronwalderslade]

I have the common positive model. Can I charge my battery directly (from a generator at 12v) with this panel connected, without damaging the solar panel?

[@ZerHour]

Hi Adam if I get an rj45 splitter can I use the mt50 and the Bluetooth device at same time ? Thanks for any advice

[@pcmalek5]

hi Adam i have a solar system with 24v 250Ah gel battery and 300w solar panel so my problem is the earthing rod, can i use my house's rod ? because neer my solar system i have an outlet with the earting cable so why not use that one

[@stuartdavies8388]

@Adam Welch Hi, I have the Tracer AN and I'm trying to use the EPever USB cable to get data to my Pi Zero W but all I get is: Realtime Data Cannot get RealTime Data Statistical Data Cannot get Statistical Data I know the your old MT50 and your diy wifi module wouldn't work with the Tracer AN. But could you try your Pi connects and can get data via USB please?

[@maraiskotze9241]

Hi, just a question if you have the MT-50 and Wireless device i presume you cannot use them both at a time its either or? Thanks for the Vid the reason I bought a tracer 4210AN

[@tahquameken]

Do you have a video on how to adjust the settings? Thanks!

[@electronic7979]

Excellent

[@SuperBrainAK]

what about the current shunt? high side or low side? if it is low side (negative) then connecting them together outside of the unit would possibly make the current go way too high (or effect the MPPT algorithm)

[@landonferguson7282]

Would this work for charging lifepo4 batteries in a 4s configuration?

[@we3ntok]

hi adam i have the tracer a series are you able to tell me y it shows volts but its not showing any amperage ? Cheers

[@m0gga]

Good afternoon Adam, it has been several years since I installed my 40w Tracer AN in my shed (2018 to be precise ) and at the time I installed two 100w solar panels on the roof. What I would like to know please is how many watts input will my controller accommodate? I am thinking of expanding it's capabilities to the maximum and making more use of the system which has languished along happily without much use at all, just some internal and external DC lighting. Thanks'.

[@popcoingaming5086]

Hi Adam. I'd like to know your thoughts on the esmart3 MPPT solar charge controller?

[@Clydesdale2045]

Did you get the eLog01 to work? I got 2 of them, both when I plug it into my tracer an they blink slowly red which seems to mean incompatible controller.

[@aguitarcalledchutzpah]

Hi there. I've set this up in my van...No inverter. What is the first things I should do and how do I do them (or once set up just leave it do it's thing without touching it?)

[@jeffreychow8853]

Very informative, thanks! Debating between this and the Victron SmartSolar. How would you compare the two? Are all MPPT’s about the same in conversion and getting max power from solar, and it’s the accessories that differentiate?

[@AdamWelchUK]

Yes probably price and accessories that make the biggest difference, but I haven’t tried the victron range, so it’s difficult for me to comment fully.

Hey Adam great videos... I have three controllers and wondered if you have connected multiple controllers. Mine is powertech but epever software works fine.

[@patrickjean-francois9156]

Is there any controller that I can set up on when to work and when not to work?

[@alanalan-mq8yw]

Glad saw this vid, just recieve same MPPT 40A, manual says it was positive ground with line connecting pos symbols, but noticed buttons were blue with black heat sink, so did test and it made sound on neg, not pos, so it is neg not pos ground, yea, thanks for vid,

[@AdamWelchUK]

Yes the A model is common positive the AN is common negative. The A model is getting harder to buy now.

[@ZerHour]

Hi Adam ,just running some tests ,I have the A not AN version installed on motor home ,solar panels are fixed frame ,the frame is connected to the body by metal brackets ,the positive and negative wires from panel go straight to the tracer I get continuity on the negative terminal solar input and the positive terminal input from my leisure battery is this normal ? Ps my leisure batteries are also grounded negative to chassis of camper . If I unscrew the solar input positive wire ,and unscrew the battery positive there is continuity between both wires ,I am trying to work it out but am at my understanding limit any help or is it all normal ? Cheers

[@RaviKumar-uy8ss]

How many wattage solar panel we can connect on this and does it support current up to 40 amps or 30 amps..?? kindly reply my thanks is already reserved for you

[@brentacusmaximus6677]

I bought the 40amp version from Amazon that comes with all the goodies like the mt50. Question ? It says it has a max of 100volts and a max of 520 solar input wattage. In your video your one 100 watt panel is putting out 31 volts which is confusing because if 3 100 watt panels put out say an average of 31v each for a total of 93 volts. How can I run 5- 100 watt panels without exceeding the max 100 volt limit ? My plan was to run this epever 40amp 100v with five 100 watt panels. Thanks 😊 🙏

[@wahyuoktaviana3410]

which one is good with the brand SRNE?

[@paulmathison2906]

Hi Adam, is the software versions different on the two MT50's, I noticed in the manual that the communication time (ID) can very up to 6 minutes. See page 24. This maybe just the time before communication timeout, the manual is not very clear. Enjoy your videos, keep up the good work!

[@AdamWelchUK]

I will check this, but the fact that my rs485 to WiFi esp8266 module doesn’t work either makes me think there’s a change on the charge controller side. I suspect the rs485 chip has changed and perhaps it boots differently or can’t supply the power the esp8266. More testing required. Cheers

[@fratermus5502]

My first instinct was they "Renogy'ed" it, whatever keeps the OEM MT50 from talking to the renogy rebrands. If renogy rebadges this model maybe EP just wanted to have one config.

[@morrisgoldin4362]

Has anyone looked at the new onesolar mppt charge controllers?

[@fourzerofour7860]

Another great video and review! Thanks! Good to know that I might have to buy a new MT50 meter. Worth it though if I can get negative ground.

[@AdamWelchUK]

I need to check the software versions on both my meters - I’ll try to let you know so you can check yours.

[@AdamWelchUK]

So the meter that doesn’t work shows version number V01.32+V01.60 in the meter para section. The meter that does work is version V2.14+V01.60 So my guess is that the first number is the software version, and the second number the hardware. Hope that helps you.

[@fourzerofour7860]

Adam Welch Thanks for the info! Getting the new charge controller will definitely require me to get a new meter it would seem; But ah well, such is life. I wonder if there's a way to upgrade the meter software version? Probably would involve something to emulate the CC to power it on, and then maybe the RS485 serial to USB interface.

[@martjeenmarkoppad1355]

Hi Adam, I have just received the Tracer5210BP.. This product seems an looks to be a winner. It has no display but offers quit a heavy packaging with great cooling capabilities. Hope you will review it and I’m quite interested what you can make of it..

[@PINACI]

Hi, I'm in the process of upgrading my shed solar power system from 2x 100w panels connected in parallel on PWM 12v lead acid and am thinking of getting the 30amp version of this MPPT. My question is this... the Epever tracer 3210AN 30a version states it's good up to 390w of PV input but I want to use 4x 100w panels, do you think the 10w difference will make a difference ? Can't seem to get a response from Epever themselves on this and I'd rather not pay the extra for the 40amp version which is rated up to 520w 12v.

[@AdamWelchUK]

The manual for the tracer A & AN series has two figures for the solar input. The lower rating which you’ve seen but also a much higher rating (for the 40 amp controller I think it’s 1200 watts). My understanding of that is that the charging current is limited to the rated output, but you can attach more solar to the input. In the event of good sun the charge controller will limit the incoming to not exceed the rated output. The advantage of this is that when sky conditions are poor, you’ll have more solar coming in than if you just stuck within the rated output. So my understanding is you’ll be absolutely fine.

[@PINACI]

@@AdamWelchUK Thanks for the reply. The specs state that for 12v system the max PV input is 390w or double for 24v, however after doing some more research into solar panels I've come to the conclusion that you will never get what it says on the tin anyway ! so my 100w panels are probably more like 80w or even less and I very much doubt I'll get their max amperage out of them unless I live in the middle of the Sahara desert either ! So I'm pretty positive that even in the perfect UK sunshine my 400w of panels won't exceed 30amps.

[@12vLife]

anybody have problems with the terminals on these failing, stripping? Can they be changed?

[@xanataph]

Common negative is really only important if you're running a complex system, as doing this with common +ve poses special difficulties. My system is such a complex one so this is a very welcome improvement. I may look at getting one of these. Have been considering the Tracers for a number of years. Trouble is that solar panels have gotten even cheaper so it always ends up expensive controller vs more panels. Panels usually win. One day I might run out of room..then squeezing a bit more out of the existing ones would then become more pertinent. But things are running very well here, 20 days out from the Winter Solstice here in New Zealand and have both made my coffee this morning & currently have the electric jug on. So it seems the system now holds up in all Seasons, providing of course the weather is fine.

[@AdamWelchUK]

Always good to hear from you Xan. I've been absolutely fine with a common positive set up for a couple of years now, but I know others don't like them, or as you say will struggle to implement them with a complicated system. I've pretty much run out of space on the shed so MPPT offers that little bit extra. Glad to hear your getting through winter without too many issues.

[@xanataph]

A basic setup with solar panels to controller to battery it shouldn't matter one little bit whether it switches +ve or -ve. Or indeed both. I have found that some small controllers do their switching in the +ve line & their reverse blocking to the panels in the -ve line (or vice versa). In these cases you can't really have a +ve or -ve common between the panels & battery. We're currently in the process of having Vikey set up his own personal little solar system with panels we bought cheap from Jaycar when they were having a sale a month or so ago. It'll mean he'll have some autonomy to run his computer on days when otherwise I may not let him due to power conservation measures. And it will also teach him responsibility and how to manage such a system. Not to mention of course he'll learn how to put one together.

[@andypag1071]

Would you say this was suitable for marine use, given the pcb protection coating? Is there anything stated in the specs about marine use? Thanks. I enjoy your videos.

Can I compare this with epever eTracer (ET6415AD)

[@azizimran8805]

Hi Adam, nice presentation. Btw, i'm abit blurry about Common Negative/Common positive solar charger mentioned in the video. What does that means?

[@AdamWelchUK]

Thanks. Common negative solar charge controllers have their solar, battery and load negative connections all permanently connected together and the switch to connect them together is in the positive side of the circuits. Common positive solar charge controllers have all their positive connections connected together permanently and they are are switched in the negative side of the circuit. It’s easier to switch the negative side in this application (which is why common positive is popular) from a circuit design point of view, but as users we tend to imagine the positive side would be switched. Both can be used in almost every environment - but a common positive charge controller in a vehicle (which is common negative by design) can cause you probable a if you don’t think about the wiring and isolation!

[@azizimran8805]

@@AdamWelchUK How about fuses and 1P circuit breakers? Usually people will attach fuses on positive side of the wires. Will the fuses/1P circuit breakers change its position when applied to this Common Negative situation?

[@AdamWelchUK]

You can still put your fuse or breaker in the positive side on both types of controller as long as there are no other routes the current can take.

My an41510 has a resistor in the temp plug. I understand to remove it to plug the sensor in, but what is it's function? Why is it needed? Thanks.

[@AdamWelchUK]

Not heard of them supplying a resistor before - I have seen a small thermistor supplied just wired across a plug before. The thermistor measures the temperature - a resistor would allow the charge controller to read a fake temperature. It would be a fixed reading but perhaps they found it works better if it can read something.

Hi Adam, thank you for the review on the AN series. I have a portable power station powered by 18650s in 3S, the provided AC adapter for charging is at 12.6V 5A. I am considering getting 2206AN to connect my solar panel to charge up the portable power station. 2 questions. First, would you recommend that this as a suitable MPPT controller. Second, do you know if we can disable the floating stage charging through the PC app? Thanks!

Hello, see my last comment (sort by Newest First) - I've just bought one. I'm new to solar, so take my words with a pinch of salt, but info is there in the hope it helps someone. I'm pretty impressed with it and exceeded my expectations, considering I don't get that much sun. Currently only using 18650 7S2P as I haven't got enough batteries yet.

great. I was hoping you would check this out for us! thanks a million. I almost got one of these . in 40 amp. in fact I thought I did. though after looking over my order. I noticed I ordered the A series. I guess I ordered the cheapest and it ended up being an A! I haven't used mine with lithium yet. would it be best to use the temp. sensor with the lithium or does it matter. thanks again..

At the moment I’ve found the AN is cheaper - new model I guess without the reputation so they’re trying to make some sales. As fit the temperature probe - it’s primary function is to adjust the charging voltage depending on temperature. If it’s cold, it charges a little higher for example. I guess that could be a problem for lithium but might not be such a big issue in practice. Perhaps there’s a test or two in there.

Hi Adam, I have two tracer A series controllers running in my system. Can I connect this AN series com. negative controller to my existing battery bank? I haven't grounded my system. it is in float state. are you using it with your A series controllers? appreciate your advice on this. thanks.

I just got "epever BLE RJ45 A BLE adapter. but now discovering it will not connect to my phone with the apps available. the conpatability said "AN SERIES", and I just figured it was the same. bummer. Fortunately I already have a triron N series coming. Nlol. Now your telling me my old meter won't work with my new controller. oh well, the old will stay with the old and the new will stay with the new. BUT now I'm more confused by you saying the "e box" bluetooth adapter works with both?

My old 100 volt , 20 amp , tracer "A" SERIES, has 2, 25 amp fuses. I think they are,in parallel. Isn't that 50 amp?

In this market at this. moment in the Netherlands everyone is speaking bullshit, no good information to be had. Resellers simply say "no this cannot be used offgrid" and try to get their feet in your door. This video finally showed me how it should be done. Many thanks!

Hi Adam could you please test if this model if you can use the new lithium app on the android market place the old model connects with wifi but won't read or write thanks luke
