- I have now created a custom board which does a similar job but with a dedicated interface store.eplop.co.uk/product/epe...
Here we have the latest revision of the RS485 to WiFi adaptor with built in RJ45 connector for easy usability.
This is not so much an in depth explanation but a build video with a talk about the board :-)
I will update the stock soon but for now the Tindie link is: -

As you know I like the improved design. Does make it easier and quicker to build. Cheers Colin
Hi Adam, it's so much quicker from not having to cut a network cable in two and tin the fine wires etc or even making one up from scratch.
Very cool Colin. Cheers
Great the Victron PWM Pro looks exactly like this solar controller. Same protocol and all. Will try to do it also.
Hey Mike, i'd just double check the pintout on the RJ45 connector though before connecting. Also the code i run is checking for specific registers on the EPEver and i would imagine the Victron would be running different registers. Worth looking into.
@@Chickey indeed the pinout indicates 12v instead of 5v for starters. I will have to redo it myself but just the idea is something in itself, so thanks for that!
Hi Colin
Great product works really well as real-time monitor of my solar setup in the shed. I see on the settings tab you have mqtt and influxdb configs. How would I use these to send the real-time data to an influxdb database I have running on a raspberry pi on my Lan? I am using RS485-WiFi v0.60 software. Any instructions would be great as to how I access the data and what format is it in plain ascii, JSON formatted?
Cool little board update. I may be questioning the obvious to you, but does it pull the power via the RJ45 cable? I have looked at the traces and assume the EPEver provides power down the cable? What would be the best MQTT charge controller to get as you said this one is PWM? Guessing here in the UK we need to squeeze the Sun as much as we can?!!
Hi Stephen, Yeah on the epever it provides 5v which is stepped down to 3.3v for the ESP. I'm using a MPPT charge controller in my live setup but in all honestly i'm not sure it's as important as it used to be now panels are so cheap. I run an EPEver tracer 3210A which is a 30A model. The biggest difference between this and say a landstar model is the MPPT but also a higher input voltage, as it's MPPT it can have up to 100v rather than 50v for a landstar. However a 30A landstar and 30A tracer are still limited to the same amount of PV input. Oh the Epever has bigger input terminals (10mm).
@@Chickey thanks!
I built a custom radio system for my EPEver systems, using that same RS485 adapter board you've used, but I've had 3 EPEver units stop communicating after a length of time, and even the factory USB cable no longer works. Have you had any issues with your equipment and had to repair? I'm assuming the internal RS485 IC has failed (looks crispy) but I can't pull any info off of it to get a replacement figured out. Have you?
Hi, I've purchased a v1.6 board and installed a Wemos D1 Mini with esp-link and my goal is to allow home assistant to communicate with my Epever Tracer 3210AN and draw some nice graphs with data from influxdb. Is there a guide online anywhere for setting up the v1.6 with a D1 Mini ? your videos so far only appear to cover v1.5 and the ESP-01 chips. Will the default pin configuration of esp-link work with this board ? So far I've not managed to get the epever software to work using a virtual serial port.
I also have seen mention that you think this could automatically publish to MQTT or InfluxDB, I would be very interested in a detailed guide on this as from what I've read on the esp-link pages this would require another microcontroller. Maybe I've misunderstood ?
Hi Colin, Ive been looking for a replacement for the standard epever wifi module for ages. I went to the website in description and it says that it run out of stock around a year ago. Just wonder if these are still sold?
Cheers,
Alex
I have 100 ready to go, sorry shall get them up soon.
@@Chickey Woohoo! Great news, how can i get them, tindie still says out of stock.
Hi, I am wondering if this will work on "AN" common negative epever tracer units ?
Tindie says: It has been confirmed tested and working on the following boards - LS1024B - Tracer 3210A - MPPT Tracer1210 - Tracer AN - TRIRON Series with RS485 module
Eplop Electronics says: The boards have been tested on the landstar and tracer controllers, it does however not currently work with the new common negative tracer model.
Hi my apologies for the Conflicting information it was the older version that did not work on the AN series but the new one works fine with it. I carried across the description so shall be sure to amend it
Another great video Colin.
One of your earlier videos inspired me to build my own wifi box but I've spent the last 4 days trying to get data to appear on the solar station software...having exhausted my knowledge and ability (although I'm now an expert in flashing 8266 modules!) I've come to think that my RS485 converter module is duff. You mention in this video that you've had a few duff ones, so could you please let me know where I can get hold of a module that will actually work???
I'm quite impatient these days so I don't want to wait weeks for it to ship from China - any suggestions would be very much appreciated.
I've learnt a great deal along the way with this project but I'm super-frustrated that I can't get it to work.
Keep inspiring us!
cheers.
Hi Adrian, sorry for the delayed response. I was struggling to find any decent suppliers so i moved onto a newer design which uses a wemos D1 and surface mount chips. Should have it out soon and hopefully start videos again.
Hi Colin, I was about to buy the Epever wifi01, then saw Adam and your videos. Are you still selling the completed units?
I shall be very soon, sorry for the delay.
very good... will it work with an Epever Upower UP3000 / M3322 ???
Not much cheaper than the official Epever Wifi adapter but as you cant join the official ones to your home wifi these ones should be much better.
Waiting for them to come in to stock.
You making them yourself Colin? or is China helping you out?
Thanks for great videos. Keep it up
Hi Paul, thanks for the comment. Being able to link it to your own wifi was the main reason i created the board so i can log to Grafana. I'm making them myself so taking my time to sort them.
btw paul if you prefer the offical model i recently found out it is still possible to put it in STA mode for now at least ua-cam.com/video/uFURiLmQds0/v-deo.html Look for a comment from St!CK3L
Hi! You can share the file GERBER and layout for 3D priter?
Hi i've switched to a new design which i'll have out soon.
Hi Colin
Is there any chance you can share the updated pcb file?
Thank you
I'm releasing a new version soon.
Hi Colin, are you still selling these ? I have a Epever 4210a
Does this work with rich-solar?
Can you explain or show any diagram from which wires you take power ??? I measured voltage from blue wir and brown on both of them there is only 3.09 volt. definietly not enough
Hi it sounds like it shall not work for your controller. With the LS1024B and Tracer3210A which i have i get around 5-6v
@@Chickey I use epever Triron with rs485 Module. So quite straange because it is compatibile also with wifi module from epever
Szymon Zieliński yup it is strange as that is where it gets its power also.
@@Chickey Can you Tell me from which colours you take The power?
On my devices pin 1 + 2 VCC / 3 +4 B / 5 + 6 A / 7 + 8 Ground
i have one doubt is i want rs485 connector bt you solder the rj 45 connector then how to connect RS485
plz reply bro
Hi. When will the kit be available in Tindie? I just checked it's out of stock
Really soon, out of interest is it the posting to a db you need or the passthrough nature?
@@Chickey Well, i want it post data to mqtt server. I'll keep an eye on your Tindie store then. Thanks
@@3dmixer552 no worries i ask as the new device can't do pass through initially but can post direct to an MQTT/influx db etc so no need for something polling.
@@Chickey That's good enough for me. Thanks
Hi Colin any chance you can knock one of your green epever tracer compatible WiFi rsj things up.my soldering crap an my epever WiFi 01 wont connect.steve near Chester.let me know how much if u have time 😀
Hi steve i do have spare PCB's but i've switched to working on a new board which will post directly to influxdb and also allow you to check it via a webpage without the need for influxdb/grafana etc.
Colin Hickey ok thanks
steve mcgowan drop me a line at chickey@eplop.co.uk and can see what we can arrange
Hi Colin I have a cordless drill park side impact driver an motor ok battery was dead an have my own lithium battery but switch on drill won’t work I’ve connected to switch that reverses polarity .my own switch works direct to motor how can I reverse polarity for drill forward reverse

something like this would work
colin looking at julian's First Look: Ming He 120V 30A Wireless Power Monitor Oct 12, 2016 ua-cam.com/video/YGp2wDAfC1k/v-deo.html its apparent after looking at his listing that these cheap diy friendly Power Monitors are using generic RS485 MODBUS Specification protocols with capability to change modbus channel,address etc built into its nRF24L01 firmware ,i wonder if the receiver can talk/control and integrate directly to any modbus EPEver RS485 to WiFi'ed diyBMS device after a little hacking?
In a standard Modbus network, there is one Master and up to 247 Slaves, each with a unique Slave Address from 1 to 247
Hey Colin, Many thanks fro your inspirational videos. Between you and Adam you seem to really know your way around the epever devices. I have posted a similar question on Adams page, but wanted to see if you had any pointers at all....
I have recently bought a Epever upower hybrid charger / inverter which also has a RS485 modbus port and would love to get to a remote monitoring dashboard like you and others mention however I am having trouble with the basics..
Before I go into the dashboard, I thought I would just try some python scripts to read the data. I looked at scripts such as github.com/kasbert/epsolar-tracer and simple pymodbus scripts such as stackoverflow.com/questions/57313343/modbus-cant-read-data-from-epever-tracer-1210a-to-raspberry
None of them worked however I could get the Windows software provided by epever to work but who wants to look at a Windows laptop !!
Have you ever tried talking to one of these upower devices ? Can you think of any pointers that may help ? Have you tried your wifi adapter with them ?
The Ebox works very good with uPower series and Android APP. I dont get the right functions though with usb to modbus cable.
Are there any code available on GitHub?
Hi Mike i'm using the ESP-Link software which is freely available.
make moar! :)
thankyou
