Page 29: Working Modes
换 英 7. Working Modes The Z21 series inverters have the following main operating modes providing for different conditions: Mode 1 ： Energy produced by the PV system is first used for the local load, the excess energy is then used for charging batteries, and then finally feeding into the grid. - Page 30 Mode 2 ： If there are no PV panels, battery energy is used for the local load first, the grid also can supply power when the battery capacity is insufficient. Mode 3 ： If the grid is faulty or there is no grid, the system can still operate, PV panels and...
