With the Zendure AB2000, you can store the electricity produced during the day and use it even after sunset. This means you don't give away any of the electricity you've generated yourself to the grid operator. Thanks to IP65 protection and integrated heating foil, the storage unit can also be used outdoors in winter down to -20°C. The app can be used to set how much electricity is fed into the home network/inverter. If more electricity is produced than is fed into the home network, it is stored in the battery and can be used at a later time. Can also be combined with smart meters from "Shelly" or other SmartPlugs for automatically controlled feed-in, depending on current electricity requirements.
