WonderWatt - is it worth it?

Wow, looks good.
Impressive.
Question: do you export all or most of your solar kWh’s or you keep all those 6000+ solar kWh for your your own domestic demand via a battery ?

MrMessy

PPK-Energy in the summer, I have my inverter set to not charge during the day, so all solar not used by the house at point of generation is exported. There's sufficient capacity to comfortably last a whole day, even if there's no solar.
We're on IOG, so batteries are fully charged at night, with any excess discharged in the evening, before starting over.
In winter, what little generation we get is gobbled up by the ASHP.

Thanks.
Good feedback.
I just got my self all registered with WW ( finally found that API ,etc ) and set up for 01:00-03:00 charging. If that works well , I will change to Octopus Flux and try that for few months.
