Yesterday, when recording the day's figures from my two solar panel systems, I noticed that the output from System 1 was about half of what I expected. Today I've kept watch on the generation from the inverter and noted that the output falls to zero for brief periods and then recovers again.  This happens every ten minutes or so. This is happening both in bright and shaded conditions.

The error light flashes and the error code says HW FAIL 3. Checking on the internet, this seems to be a relatively common problem and most people are saying that the Sunmaster series is rubbish. They say it's not worth repairing. It probably isn't worth having it repaired, but I'm quite capable and competent to work on the inverter in my workshop. Has anyone had any experience of this problem and its cure?

If I can't find the fault I will have to buy a new inverter. Whilst the XS3200 has only a single MPPT, I'll be looking for a dual MPPT unit as I have quite serious shading on one of the two strings which feed the inverter.

Any help would be appreciated.

With the cost of new inverters its not worth bothering with. A brand new 3.6kw 2 MPPT inverter like a Solis is only 400. Just buy a new one.

I've just gone ahead and bought a 3kW Solax.  Should arrive next week.  The old inverter has almost given up now; 32Wh total today!  Fortunately, at this time of the year I'm not loosing too much.  The failure has happened at the right time of year!

I purchased the WiFi dongle as an add-on for the inverter (it plugs in on the lower edge).  Having set up the WiFi connection to the cloud I am now able to monitor the output from the inverter using their cloud app (not their portal app).  You can also change the inverter set-up via the app which saves me having to climb up into the loft to do the final settings.
