Views required please, I have a Mitsubishi single to three phase inverter on my lathe and I also a Jaguar and a 2.2kw Mitsubishi on other machinery.
I appreciate I should ideally fit RFI filters, however it is potentially more important as I am about to have Solar panels fitted.
Has anyone any experience using filters and are generic ones ok or do you need specific manufacturer one’s?

Tried to paste link to one on ebay without success but this is the item number 331231707786 Phil

David Jupp:
Not much detail to judge that one on (and I'm no expert).

One thing I do know is important, the filter should be mounted on the same (earthed) backplane as the inverter and as close as practicable to the inverter.  The mains feed to the inverter should be via the filter, with no intervening components.

PK:
The only problem you may encounter using a generic filter is that it may not attenuate the noise enough, conversely, it may be overkill for the job. The manufacturers filter will have components selected to get the noise levels below an accepted standard.
If you can find the inductance and capacitance values used in the manufacturers filter, then you can select a generic version with confidence.

For my machines at home, (which all run from 240VAC single phase) I just use a generic filter like this: http://www.jaycar.com.au/Passive-Components/Ferrites%2C-Inductors-%26-Suppression/EMI-Filters/240V-AC-EMI-Filter/p/MS4001

Have you spoken to the company installing the panels? If they have done any commercial places they may have come across this issue befor and may be the best ppl to advise.

I am using a   comercial electrical company for the solar panels rather than a firm that has moved on from seling upvc windows, drives or conservatories. They should be able to advise, no dòubt they will say yes to filters, I was just seeing what others had done
