SolarEdge SE2200H

wheeto · Apr 25, 2020

Hello,

I've moved in to a house with a string of eight panels in series, connected to a SE2200H . The previous home owner had the inverter replaced about two year ago. Since I moved in, I've always thought it's "not been quite right" but hadn't found the time to investigate fully. Well, today's the day!!!

At points today I've seen it putting about 1.5KW of A/C out, so I now know that it can work. However, I've had the following errors at various times, each time requiring a complete reset:

Error code 18xB7
HW Error

and

Error code 18xC7
RSD Error

Can anyone provide any insight further than the install PDF I've managed to find?

My second set of questions is around remote monitoring. The inverter is in the loft so very inconvenient for direct monitoring / troubleshooting. I've connected it to the network (hardwired) and it's taken an IP address but a port scan shows nothing open. I know nothing about these devices ... is there any free software I can use to monitor it? I see that there's an open-source project who have implemented the SolarEdge protocol, but that requires that I extract the encryption key from the inverter over a local RS-232 link. That would be fine, except it seems that my generation inverter has had the RS-232 port removed! I have a pair of RS-485s and a module which seemed to provide ZB and WiFi, which I've unplugged from the main board as I didn't want to use it.

Any advice very gratefully received!

I realize that questions about inverters are probably quite specialized for an electricians' forum; are there any other UK-biased sources of info on the 'net that people would recommend?

We are a Solar Edge Professional installer in Yorkshire. I recommend you try Solar Edge's support office in London (although their technicians are probably working from home at the moment): Contact Us / Offices | SolarEdge - https://www.solaredge.com/uk/corporate/contact

Before you phone them, note down the serial number of the inverter. It will be on the nameplate on the side of the inverter. SE will then be able to tell you whether or not your inverter has ever been set up for remote monitoring.
