Blueprint imported and testing.

Huawei hardware:
Inverter - SUN2000-5KTL-L1
Batteries - LUNA2000-5KW-C0 x 4 (20Kwh)
Panels - 16 x 400w Eurener (6400w)

Rates:
Tariff is Octopus IOG

• Import peak rate £0.28
• Import off-peak rate £0.07
• Export rate £0.15

Location is the Midlands, UK
The car charger is wired separately, and no automation is required.
Nordpool is not necessary on the IOG tariff

HA integrations installed:
PredBat
Solcast
Huawei Solar
Octopus Energy

Thank you for the work. I could not get Bradbat to control the Huawei inverter, so I have been using my own automation.
I will feed back on the results.
