I have already hosed the panels heavily a number of times and not caused any issue

Oh. I don’t recommend spraying the back of the panels.

One of the times the inverter turned off it made a funny noise and wouldn't turn back on straight away and for a minute I thought it died.

Ah. This could be the power supply capacitors on their way out. This sometimes results in the power supply collapsing, recovering, restarting the DSP, and repeating, sometimes a few tines per second, iften with the LEDs flashing. This is a moderately easy task to fix if you are good with electronics. See this post (page down a bit):

This possibly explains why it happens at night, when the battery voltage is lower.

I'm afraid I'm not very good with electronics. I suspect it might be hard to find someone good here. I am sure there are people, but not sure who or how to find them.

When the bus voltage 08 error happens, the system reboots itself after seconds or a minute and the power comes back on, but if you leave it on UTL with the panel switch up, it then repeats the error and on the second or third time shuts down until manually rebooted.

I was able to feel the flow of electricity when I touched one of the panels (front surface, so presumably just touching the glass) a few days ago. I wouldn't call it a shock exactly. That made me wonder if that was the defective panel causing this issue and whether removing that one might solve the issue. I don't see any damage to it.

When I felt the electricity it was late afternoon / early evening, but not gone dark, so it would have been generating. It was also very wet as I had just sprayed it.

If the panel is operating correctly, that should not happen. I think that's a reasonable clue. Bypassing just that panel temporarily seems like a good idea.

But there may be other panels compromised. It might be good to find an alternative to the "human multimeter" for testing this, though! 🤪🫨⚡

Edit: It may be the wiring or connectors rather than that panel, so don't be too disappointed if bypassing that panel doesn't solve the problem.

I felt the current from a second panel, again when wet. Again, I wouldn't call it a shock, but I could feel the flow of electricity.

So my removing one panel idea doesn't seem to work. I think I'm going back to just using the workaround I mentioned earlier.

Maybe the Risen panels are a bit cheaper and lower in quality than others or slightly defective or someone didn't take care when transporting them, they have been moved about a bit. I suspect they are safe to touch when dry or at night, just not when wet and generating.

I think I am genuinely more susceptible to electric shocks than other people. Most people I suspect don't believe me since this doesn't seem to make a lot of sense but I did used to have a lot more shocks than other people. There were multiple cases when after I got an electric shock from say a light switch and other people touched the switch immediately and said that they felt nothing. I also had to stop touching the handrails of escalators to avoid shocks, and had a lot of static electric discharge shocks. I just asked Chat GPT and Claude and one said that there is significant variation by individual differences in skin thickness, structure, hydration of the skin itself, and sweat-gland density, resistance/impedance of tissues inside the body and the other gave a very similar answer. Claude and Chat GPT tell me that dry skin resistance across some individuals might be 10x than of others (very rough number). I do also easily cut myself while shaving - maybe I have thin skin.

I will stop touching the panels when wet!
