Anyone use Givenergy batteries with Octopus?

[DrFfybes]

Not sure about the best board for this, but....

My niece is getting a Givenergy All-in-one this week. She's already with Octopus and has solar panels, but with these batteries there is an option of using the Octopus Intelligent tariff where they control when it dis/charges, or the Flux where it is different rates at fixed times.

Anyone got any experience of the intelligent one - ie the sort of import rates you pay?

She's a very high user.

Thanks
