<p><span style="color: rgb(13, 13, 13)">The bidirectional energy storage inverter from the GoodWe EM series operates with grid-connected systems and off-grid systems. During the day, solar panels generate electricity that can be used to power loads, export to the grid, or charge the battery according to its configuration. The stored electricity can be used to power loads during the night. The battery can also be charged from the electrical grid through the inverter.</span></p>
