Best Sub-board for 8.1kwh Solar PV?

Raymond Stell · Jan 22, 2019

Hi,
Can you advise the best and most suitable Sub-board for an 8.1 kWh Solar PV System, with Battery and 2x Inverters, Energy Diverter and Gateway? It will be separate from the main household RCD.
Thank you.

Can the installer not advise on this? They usually supply their own

They could, but they unfortunately used the main household RCD initially, and it keeps nuisance tripping:-/ So, I’m seeking my own clarification on which sub-board would be the most appropriate.

Ah I see. Well hager is a good brand but generally pricey. You could also use an rcbo in your original board rather than a new sub board

Thanks Matthew, I do have a Hager, which is what they have used. From other threads on here members have recommended a Sub board. Is there a particular model, rating or type that is suitable for my system?
