We already have a 5.6 kW solar array with a first-generation 5 kW inverter and a first-generation 8.2 kW battery.

We are planning to install a second 7.6 kW array with an all-in-one system (13.5 kW battery) and a gateway.

Currently, we are using the Intelligent Octopus Flux for import and export, which manages the battery.

Does anybody have experience or knowledge of how this would work with a second battery and inverter within the portal, and also if Octopus will be able to manage both systems? If not, how do I manage the second system with Octopus?

Thanks for your help.

I have two inverters on my account and I was unable to enrol to OIF. Despite lots of attempts (and conflicting stuff in the FAQ about multi-inverters), Octopus developers came back and confirmed that they only support a single inverter on an account. Their solution was for me to get one inverter moved to a separate account (which would obviously be a pain for administration).

If your AIO is setup on a new account then you could control the other inverter yourself manually. From what I learnt Octopus couldn't do it.

You would need to decide how you are going to stop the inverter and AIO from cross charging. I posted a list of the different ways I know to do this on another similar thread about a week ago.

geoffreycoan thanks for the quick reply.

Please can you post a link to the thread, as I couldn't find anything when I searched the community.
