content: I just had solar panels installed at my place and the Bosch inverter has an Ethernet interface for monitoring etc... It has one of these Amphenol industrial connectors on it (see image). Whilst I could plug a regular Ethernet cable into it, the connection won't be weather-proof.Does anyone have any experience with these connectors? Can you buy just the plug part of it and make up your own cable or do they come as manufactured cables? Any ideas where to get them? I just need a short lead to run into the adjacent meter box where I already have an Ethernet port installed.

content: I think that'sAmphenol RJF. You can buy just the plug but they are not cheap:http://www.mouser.com/Amphenol/Connectors/Modular-Connectors-Ethernet-Connectors/RJF-Series/_/N-wos3?P=1yzsgyeZ1z0zp68

content: Ouch, that is pricy, but damn if that isn't the sexiest little RJ45 I've ever seen.

content: The Amphenol RJF won't fit. It has an outer shield that doesn't match anything on the inverter.The Altronics one does look right though.

content: You know, with water resistance being important, I'm surprised they didn't use an optical connection actually.

content: Quote from: XOIIO on February 08, 2016, 05:37:40 amThe ports are all mounted on the bottom of the inverter so it wouldn't cop any direct water spray. I'm more worried about humidity/temperature causing condensation inside the port. It probably wouldn't do it any good. At the moment it has a screw-on cap with a rubber insert to keep the crud out.I might give that Altronics one a go. It looks to be right. The connector on the inverter is definitely a LTW series (it's stamped with "ALTW").Quote from: XOIIO on February 08, 2016, 05:06:03 amIt does look pretty awesome. All the connectors are of the same style. It is a proper Bosch though, you'd expect those nice touches. It was also the only inverter I found which has an actual ethernet port on it! (I did a bit of shopping around various retailers and most of them had inverters with Wi-Fi only with no option for Ethernet! Grr.)

content: Spoke with Altronics, this is the correct part to suit Amphenol LTW:http://www.altronics.com.au/p/pa9708a-amphenol-ltw-8p8c-rj45-screw-on-line-plug-housing-ip67-waterproof/It slides over the Cat5/6 cable before the end is crimped. It replaces Altronic part numbers P9712 and PA9708 (those are now discontinued).
