Can I install an RFI / EMI filter (designed to increase efficiency with a photvoltaic (PV) solar energy inverter) to an existing solar system without jeopardising my feed in tariff?

Three of my older pond filters have an integrated U/V assembly in the filter lid, which is raised well above the level of the water in the filter and therefore never intended to get wet (at least, all the while that the lid pipework itself remains sound). One, unfortunately, overflowed, so...
Noise filter will be in between wall 240V and device.
If the device is rated at 10AMPS then what AMP noise filter is required? Is it 20% above device rating?

Hello,
I have a pond filter, that has a short (3-4m) run of flex to a junction box, and I want to protect it, but can't decide on the best conduit. The flex will be discreet but not buried, and will run with the hoses from the filter across a flowerbed. (It's at risk of boots & hand trowels...
