summary

Home system runs 26.5 kW of PV and ~25 kWh of battery storage, monitored with an SDM630V2 three‑phase Modbus meter on an Orange Pi over RS‑485 feeding Open Energy Monitor. Solax hybrid inverters are micromanaged by writing their remote wake and charger power registers to enforce phase‑level zero power and a holistic 3‑battery sharing scheme; export is limited to 5 kW per phase. Home Assistant + Node‑RED and TWC Manager control loads and a Tesla charger; trading spot prices via Amber has netted up to $84 in a day.
