Model notes

Source: ET LV datasheet, 9 September 2026, EN V2.1.
Do not mix different battery models in parallel on the same battery input. The series supports compatible GoodWe Lynx A G3, Lynx U G3 and Lynx A G4 batteries as well as other compatible brands.
Above 980V PV input the inverter enters standby; normal operation resumes below 950V. Refer to the user manual for the MPPT voltage range at nominal power.
For Brazil, Chile and Sri Lanka, maximum active power equals nominal power. For Chile, maximum apparent grid output equals nominal apparent grid output.
Optional functions or devices are purchased separately. Specifications may change as products are improved; consult the linked datasheet and the latest manufacturer certificates.
Standard replacement warranty: 5 years, as specified by AJ Solar.
