Hello, new to the forum, hope this is the right place for this question..
I have soalr panels on my house (they work great, had them for several years)
I recently had a Marlec Solar iBoost installed, which diverts the exported/excess elecricity to my immersion heater to give me warm water without running my boiler.
This also works great with one exception.. my ADSL connection stopped working whenever it kicked in (oops!).
I contacted the manufacturer who said my ADSL filter was bust and the change it for a new one, which I did and the internet is back up, BUT it is still slower (drops by about 25%) whever the unit is working.
I was curious so I put a scope on the mains supply and to me it looks very noisy, basically whever the iBoost is on there is a +/-10V 20kHz ripple in the AC. And at high frequency there are lots of little spikes which dance about that go away when it turns off.
I am interested in if if this is acceptable/normal for this kind of device. the manufacturers view is that this is normal and it is my ADSL filter that is faulty, but for my money, it should not make this kind of noise in the 1st place...
I don't have access to the relevant standards (paywall) :-( and although I know a bit about electronics from my day job, this kind of circuit is not my area. Hoping there are some experts out there on this forum.
I've been through a few days of tests and back and forth on this and wonder if there is a real proble or I am just fooling /making a fool of myself
Pics attached from the scope..
