Hello professionals out there! This is my first question on this forum.
I am not a professional and have no electrical qualifications.
I have a PV and battery system. The battery was installed in 2016 and is still under guarantee. It is a Samsung 3.6 KW in the A10 series. Samsung have now stopped that side of their business and have passed it over to Hansol (who apparently made the thing for Samsung in the first place). It was installed by Avonside Eco Homes, which was a subsidiary of Avonside Roofing, but is no longer trading.
Recently, the battery system has started randomly shutting itself down. Switching it off at the main isolator and on again resets it, when it will run again for random amounts of time - it could be a minute or two, or some hours or even all day.
I contacted Hansol's service department, who monitored it remotely through its internet connection and said that over-voltage on the grid was causing it to trip. They said it is set to trip in excess of 253 volts. I contacted Western Power Distribution, who thought this unlikely, but fitted a monitor to record voltages continuously for a week. During that time the A10 continued to trip randomly, but the grid voltage never went higher than 245.8.
In the meantime, I had noticed that the system only tripped when the Immersion controller was set to automatic. Ours is an Absolute Energy Master, and was installed by Avonside as part of the package that came with the battery. I pointed this out to Hansol, who said that they didn't know what that was (although I told them) but that the A10 is not designed to run with one. Absolute Energy have now gone out of business, so I cannot pursue that line. Avonside now have nothing to do with batteries, only PV panels, and Avonside Eco Homes no longer exists, so no joy there either.
My suspicion is that the immersion controller is not to blame, as I have two - the other is running a heater in the hall (only used in winter, when the hot water is produced by a back boiler in an Aga, which we turn off in summer and use an immersion heater). I have tested the second one, and the A10 trips randomly with that too. It seems unlikely that both would fail in the same way at the same time. Also, much more recently I have noticed that if I don't switch the immersion controller on (i.e. to automatic) until the battery is nearly fully charged (85% or more), then the system does not trip, but works perfectly, with current fluctuating correctly with the level of sunlight and other appliances being used.
So, if anyone has managed to plough their way through this and got to this point, do you have any ideas about what the cause of this might be and whether I can get anything done about it?
