Replace existing RCD with RCBO when installing Easy solar 11 250/100 GX

Good evening , I am going to replace my existing working Epever Hybrid with a Easy Solar including Pytes 15 kw battery.

I have a old but working 30ma RCD on the incoming supply which will feed into a designated housing for 2 x40 amp MCB`s

[ these are double pole, Bcurve ] for the inverter in and out . after which is my consumer unit with MCB`s

I am thinking ,firstly do I need RCD with the easy solar if so would it be better to swap the 40 amp MCB`s for RCBO type B

Firstly, due to the sequencing of the internal neutral grounding relay of the Multiplus, you can’t use an RCB on the input side - they mostly always trip.

Best to fit the multi on the input side, then connect the existing load circuit on the output side.

Thanks Mike ,

Am I right in thinking the easy solar 5000 GX 250/100 already has an internal RCD ,this seems to be what the sales blurb says .

So no RCD needed as all incoming goes through the multi {I will confirm this with the sparky but im trying to get everything I need on site}

and leave the consumer unit as MCB`s .
