EcoBSS / FLEX warnings & faults
Register bit maps for EcoBSS Flex hybrids: three-phase LV (FLEX 3L) and three-phase HV. Match the code on the display to the correct family tab.
Source: EcoBSS Flex register map V1.2. System names match the English token in the vendor bit list. The same Fn/Wn can differ between 3P LV (FLEX 3L) and 3P HV — pick the family tab that matches the inverter.
EcoBSS three-phase LV / FLEX 3L class — same code number can differ from the HV map.
