How powerwall 20 kwh works?The working principle of the wall mounted lithium battery energy storage system also depends on the mode. For example, in SE mode, users can set the SE time; During SE time, the power supply of the load is provided by the mains bypass input. At the same time, the mains charge the battery, and the solar charge the battery until the battery is fully charged. Outside the SE time, the load is powered by solar energy. When the power generated by solar energy cannot meet the user's load, the load is supplemented by the battery pack; When the remaining capacity (SOC) of the battery is less than or equal to 10%, the wall mounted lithium battery system will automatically switch to the mains power to supply power to the load, and will start the mains power to charge the battery, at the same time, the solar energy will charge the battery until the battery is fully charged, after which the system will automatically switch to the solar energy and battery to supply power to the load. When the battery power is seriously insufficient and AC (mains power) is cut off, the system will automatically cut off the load power supply, and the solar energy will charge the battery, SOC will be charged to 40%, and the load power supply will be restarted; If the market power is connected during this process, the system will automatically switch to the mains power to supply power to the load, and will start the mains power to charge the battery, while the solar energy will charge the battery until the battery is fully charged. After the battery is fully charged, the system will automatically switch to the solar energy and battery to supply power to the load. For example, if the user sets SE mode, assume that the setting time is 1:00AM-6:00AM, before 1:00AM, the system will be powered by solar energy and batteries; During 1:00AM-6:00AM, the system automatically switches to the mains bypass to supply power to the load, while the mains and solar power charge the battery until the battery is fully charged; Until 6:01 AM, the home battery storage system will switch back to the way that the load is powered by solar energy and batteries. For countries and regions where electricity prices are measured by time of use, users can set the function of staggered power consumption according to their needs, use the power of the grid during periods when the grid load is low and the price is low, and charge the battery pack for standby. During the peak load of the grid, the electricity stored in the battery pack is used to achieve the purpose of staggered power consumption and electricity cost saving.
