Wow the subject of rcd s I have been doing on about for a few years. It got to the point now where I actually always contact the inverter manufacturer and in nearly all cases they come back with a list of devises normally type A and bidirectional and min of 100ma to 300ma. So I tend to follow the manufacturer's recommendations and always fit an separate CU to accommodate the 100ma. Keeping away from the main CU. Same with EV chargers. It's deffo good to contact the inverter manufacturer to be 100%.
Looking at the latest manual for the SunSynk 3.6kW Ecco it states a cable size of 6mm to the grid, along with a 40A MCB/RCBO. I think this is because the inverter can be wired to pass up to 35A through from the grid to a backup circuit. I guess even if the inverter isn't configured with anything connected to the load terminals initially, it might arguably be safer to go with 6mm/40A in case a backup circuit was added later without consideration for the grid passthrough.
Don't forget voltage rise at the inverter comes into play too. There's no point in having 3.6kW of capacity if the voltage at the inverter rises high enough to force it to limit current to keep the voltage in the acceptable window. A street supply towards the top of acceptable voltage can be enough to cause it even with a modestly sized solar installation.

adam loves 16a breakers instead of 40a

why would the cables need to be the same length to charge the battery's equally?
I just dug out emails for Growatt, solis, solax and soleredge all stating min 100ma and other modules 300ma type A
I’m glad I don’t have solar and never will.
why? im literally spending half my income on electricity due to the datacenter so solar would be a godsend
Yeah I don't understand people like you. Why pay 200 euro per month when I can pay nothing.
Hahaha! Sucker enjoys being a slave to big business. I prefer freedom.
I'm 9 years in and in that time have gone from buying electric at 10p to 24.5p a kWh so making 3000+units a year is worth it to me.
what a silly comment
