I have 8.8kW Solar / 20kW Batteries / 7k Inverter installed. Firmware versions are Master 1.41, Slave 1.01, ARM 1.37. I am on Octopus Flux so wanting to take advantage of import / export as follows :
- Charge batteries to 90% in the 2am - 5am lower import tariff period
- Dicharge my batteries to 30% in the 4pm - 7pm higher export tariff period
- Use batteries / ongoing solar generation in between and export anything above 100% battery capacity straight to Grid
For some reason it is not exporting to Grid in the 4pm - 7pm period. Also it seems that once I reach 100% battery carge in the day the Solar PV generation matches the Load required and I never trigger discharge to the Grid. Import in 2am - 5am period to charge the batteries is working fine. What am I doing wrong? If nothing, is there a chance that hardware is not configured right? Appreciative of any views and advice.
