Yes, there are ... same as solar PV.

There are legal limitations on connecting parallel generation, see Regulation 22 of ESQCR in Great Britain, Regulation 23 of ESQCR(NI) in Northern Ireland.

In addition, there are cases where it might damage residual current devices in the installation - see video and details regarding Amendment 3:2024 here: https://electrical.theiet.org/bs-7671/updates-to-18th-edition/

Finally, it's possible to overload final circuits in to which these devices connect. General socket-outlet final circuits are not suitable. The circuit needs to be specially designed, or you need to use a dedicated circuit (Regulation 551.7.2 of BS 7671), and also check the consumer unit won't be overloaded (same Regulation).

Thanks, So in theory if the device is type tested to G98 and registered with the ENA then installation would just require registering with the DNO in the UK? But for every European member state there could be different rules and regulations to follow?

In theory ... but it can't be simply plugged into a socket-outlet.

It must be installed in accordance with BS 7671, which will mean a dedicated circuit and a means of connecting other than a plug.

These kinds of power supplies would almost certainly have large DC potential that don't have simple seperation to the supply side and so any RCD protection would need to be type B.

In a power electronics lab you ideally want to avoid RCD protection on the EUT and ATE supply. Interlocked guarding, IT supply with earth leakage monitoring, non-conducting location etc are all typically more appropriate methods of protection. You certainly don't want type A's.
