Less than 4 milliseconds (<4ms). This UPS-level switching ensures that computers, TVs, refrigerators, and other sensitive appliances continue running without any interruption during grid failures. No flickering lights. No rebooted devices.
Yes to both. The ET LV series operates with a 48V battery system (40-60V range) , compatible with GoodWe Lynx A G3, Lynx U G3, BAT 14kWh, and standard 48V LiFePO₄ batteries with CAN/RS485 BMS. It also supports battery-less operation — you can start with solar-only and add storage later .
5-12kW models: 2 MPPTs | 15-20kW models: 4 MPPTs Max PV input voltage: 1000V Max PV input current: 20A per string PV oversizing: Up to 200% This allows the inverter to handle complex roof orientations, support high-power 210mm PV modules, and maximize solar harvest even in low-light conditions .
