## Customer Reviews

### ⭐⭐⭐⭐⭐ Great product
*by  on Reviewed in the United Kingdom 2 August 2026*

Great product. Static Ip configured by default. Fast GUI. Straightforward configuration.Perfect for RS485 solar inverter access.

### ⭐⭐⭐⭐⭐ Great module but you need some expertise and understanding.
*by  on Reviewed in the United Kingdom 4 December 2022*

You will need some networking experience to understand this module and to set it up, it is not a plug-n-play item, I write the following general comments of my particular usage for other like-minded people, as this is he sort of thing I wanted to know and what could be achieved with this before purchasing.The intended use for this converter, was to remotely control and monitor my DIY solar shed project,The shed is 50m away from the house thus wifi would not work, so this converts the RS485 output of the Epever solar charge controller into an ethernet signal and that is cabled back to a network switch at the house network,The Epever control software only works with serial ports so it was necessary to have a TCP/IP to virtual com port installed on the PC which adds to the complication, but that's another story.There's good documentation downloadable from the Waveshare website for this item as it doesn't come with any.The whole set-up works great. No problems with the Waveshare RS485 to Ethernet module, it powers happily though DC swings from a 12v to 15v battery, and I am hoping to daisy-chain the RS485 shed network with other 'gadgets' which can all be remotely controlled on the same ethernet cable.The converter comes with it's own built in web page to change settings etc.As I said initially, this is for the keen DIY'er or technician as it does need some knowhow.The unit has no mounting holes so I had to get a rail for it, but these are available from Screwfix and elsewhere.Overall it is a job to set up, but works well and an was an interesting experience, the Waveshare 485/ethernet converter is well worth the money.

### ⭐⭐⭐⭐⭐ Works great if you have the IT skills
*by  on Reviewed in the United Kingdom 19 May 2023*

I used this with my Solax inverter to get data via home assistant. I installed in in a small housing that was a couple of quid from screw fix. The clever bit is getting it to work. I was lucky enough to have somebody prepared to take the time to walk me through the setup. (When the middle light turned blue, it was connected.Now that it’s done, I can get real time data (every 10 seconds) farther than the 5 minute intervals provided as standard by Solax.It does what it’s supposed to do but I can’t pretend that I know how it does it 😀
