RS485 to WiFi adaptor for EPEver Solar Charge Contollers

Glad to hear you online again Adam.

The MQTT is a great touch!

Show 👍

These look awesome! Does "Tindie" send confirmation emails? Asking for a friend! ;)

Good stuff by Colin again! :)

I’ve been using a home made version of this type of adapter for several years, but recently switched to using the Elfin EW11 (I use the “-0” version with an external antenna) and the Mdbus flex-getter node in Node-Red.
The advantage of this approach is that you can use the EW11 as a virtual remote serial port, so with the correct drivers you can access the EPEver via the manufacturer’s remote management software. This means that you can tweak the configuration without having to go and plug your laptop into the controller.

Can I connect it in parallel with the existing MT50 remote thing? Thanks.

I know nothing about all this MQTT how hard is it to just hook it up to the epever and see it on my laptop?

I have implemented an alternate approach. I use an esp32 (running a modbus library) with a cheap ttl to rs485 adapter. Code is C++/Arduino. The esp32 gets status and commands my epever tracer controller (via published online protocol definitions). The commands and status pass over an MQTT broker to a node-red server via wi-fi. In node-red I have implemented a custom epever status page similar to the factory supplied program, but which I much prefer. I have a second node-red page where I can change the various epever charging parameters.

Great to see you back 🙂

Super 👏

Good to see your still playing with solar stuff dude

I have a question.

I've been using an Epsolar ET6415BND 60amp for years.

With the standard supplied RS485 USB cable. the wires were slightly bare and came together. Since then it doesn't work anymore.

What's wrong, internally the RS485 chip in the charge controller is broken. or the USB to RS485 interface cable is broken.
is there anny protection in the charge controller.

So I got the epever bluetooth low energy one and it's ok but sucks because it wont show in real time information u have to refresh it manually

I need help with a charge controller I need a charge controller that will not only take a wind turbine generator but solar panels as well can you help me with this

Adam thanks for posting this info, very informative. I am very interested in a RS485 to Wifi board, but my problem is I am running (2) TracerAN charge controllers in my RV and to manage there charge rates I have installed the Epever parallel controller (PAL-ADP-50AN) that controller only can be monitored with wired/PC software.... yuk! The PC software works via USB/Rs485 cable, guessing the protocol is a one off. Any ideas?

I bought one, and I set the network name and password. How do I get the information to be viewed in the browser? Greatful for some help.

Witam. Da się cos zrobić aby zintegrowało się to z zakładką Energy z Home Assistanta.

I had been doing a ton of research working on building this myself and then a few weeks later this video popped up... exactly what i wanted to make in an even more compact state. Ordered one, very hopeful to see how well it works.

Is there a way to make this work with a Victron 100V 30A controller with the VE Direct port?

can this device be accessed over an other place like a online server?

I have mppt Techfine 60A, green case, with RS485 Port on it...
Can i use for monitoring ?

Hi Adam, it’s quite long ago you did this with Colin I believe, but still a great video 👍

Anyway have you done similar thing with ESP32 and new Blynk IoT?
Appreciate if you can share, if any.

Thanks.

Can I ship this adapter to Brazil?

Hello Adam
is there any HOWTO to go on after flashing the wemos??

I bought one, connected to EPEVER and I can see RS485-WIFI with windows.... But can't get further... There is no manual (or URL ?) to connect it. Any help ?

Has anyone tried this with the junctek 2023 version battery monitor?
