Powerwall 3 not leaving space for Solar
Hi all
Odd issue struggling to resolve. Around a week ago I had a new solar system installed adding an additional 11kW system to the existing 3.6. I have 1 Powerwall with x2 expansions for a total of 40kW storage.
Electricity tariff is Octopus cosy with import off peaks at 10p, mid peaks at 28p and peak at 40p. Export is fixed at 12p.
Back-up reserve is at 20% in TBC mode. Export is limited to 6.5kW
What I am finding is that the Powerwall will charge to 100% during the off peak rates, leaving no space for additional solar during the day. In theory the Powerwall should be trying to get most of its charge from the solar instead of the grid.
Instead it fills the battery, and then clips any solar that cannot be exported or used by the house.
While self powered mode could resolve this, it would require monitoring in case I use too much electric and it starts topping up the batterybwith the grid during higher rate slots.
I do make use of Netzero which can automate most of what I need but the TBC mode should be automating this itself I thought.
Any ideas or help at all please?
Sorry for formatting, made on mobile
TLDR - Filling battery to 100% from grid and clipping solar.
Thank you
