GoodWe ET 5–10 kW: battery compatibility
The ET 5–10 kW family is a three-phase high-voltage hybrid platform. GoodWe's battery matrix identifies supported battery families and firmware thresholds.
Example of why conditions matter
GoodWe lists BYD Battery-Box Premium HVM combinations for ET variants and specifies minimum ARM firmware levels for some pairings. A battery-family match without firmware verification is incomplete.
Backup
GoodWe documents UPS-level switching to critical loads. BecSpec does not translate that into guaranteed whole-home three-phase backup.
