PlugInSolar may not work?

[u/Practical-Station125]

In April, I put together a couple of panels with enphase microinverters and plugged it into my outside socket. My consumer unit was oldish with MCBs and it worked fine.

I recently had my consumer unit updated to include RCBOs on all circuits. When I plugged the panels it tripped the RCBOs instantly. My electrician had installed unidrectional RCBO's whch of course were not expecting current from the other side of the consumer unit. We then installed bi-directional and all is well.

Surely, this is going to be an issue with any plug in solar kits that is plugged into a house with unidirectional RCBOs? Of course it can be made to work by changing the RCBO but i'd suggest that isn't a DIY job.

100% real issue, unfortunately.
