Solar iboost panel dead

[rach74]

That seems rather odd, are you sure he was an electrician? There seems to be very little in the iboost to cause a fuse to blow, far more likely down to the immersion heater, however if an immersion heater fails more likely it would trip the RCD or RCBO than the fuse, unless you are in a very old house without that protection.

I went to the manual to check, I was rather surprised not to see a requirement for RCD protection. All it says is 16 amp MCB or 13 amp fuse. Since it uses DC I have actually wondered what type of RCD should be used.

He said could be to do with immersion but the fuse he said was not the one in the I boost but the box under that it goes into, Sorry I'm not technically minded but it's just the box that you switch on and off which goes up to the booster.
Electrician was also confused as if it was immersion then how come it works when heat pump kicks in, I just said leave it as at least we have hot water

Since answering seen this video on repairing the iboost, not some thing I would tattle, but it does give an insight to what is inside it.

Nice, so a £6.57 part, interesting as these seem often crop up on the forum having died

I had same problem bridge rectify short cct,fan l felt bearings worn so replaced that also thought sink not getting sufficient cooling cause br to fail.
