Ultra Thin 90MM Slimline Powerwall Battery is a Tesla Powerwall alternative solar battery. It is a rechargeable home battery system that is installed with a solar panel. When the sun rises, solar begins powering the home. When additional power is required for the home, the home can pull it from the utility grid.
ZECONEX Powerwall battery is charged by solar during the day, when solar panels are producing more electricity than the home is consuming. Powerwall battery then stores that energy until the home needs it, such as when solar is no longer producing at night, or when the utility grid is offline during a power outage.
When the sun comes out the next day, the solar recharges the Powerwall battery so you have a cycle of clean, renewable energy.

The Ultra Thin 90MM Slimline Powerwall Battery is wall-mounted and can be easily fixed to a wall or other flat surface without taking up additional space.
The most important feature of this energy storage battery is its ultra-thin thickness of only 90mm, which gives it a significant advantage in terms of space utilisation and allows it to fit into more compact installation environments.
The slim design is not only easy to carry and transport, but also allows the energy storage cell to be flexibly installed in a variety of scenarios, such as a Villa, a Household, a farm, a base station, a field power supply, and so on.
The solar electric battery storage feature allows the cell to be used in a variety of scenarios where a backup power supply or energy storage system is required.

There are 4 working modes and statuses of Powerwall BMS: charging mode, discharging mode, standby mode, and sleep mode.
When the BMS(battery management system) detects that the external charging voltage is ≥ 48V, and the cell voltage and temperature are within the chargeable range, the charging MOSFET is turned on for charging.
When the charging current reaches the effective charging current, it will enter the charging mode. Both charging and discharging MOSFETs are conductive in charging mode.
The battery monitoring system enters the discharge mode when it detects that the load is connected, the cell voltage and temperature are within the dischargeable range, and the discharge current reaches the effective discharge current.
When the charging mode and discharging mode are not met, the battery management system enters standby mode.
After the specified time of normal standby, the battery triggers undervoltage protection, executes the key shutdown, or the upper computer executes the shutdown command, and the BMS enters the sleep (shutdown) mode. Ensuring the charging is active and then pressing the key to start, the sleeping mode is woken up.
If there is a fault and the battery gives an alarm, check whether the battery is connected correctly or whether there is overcurrent.
Then press the reset button to see if the fault is eliminated after the battery is reset. If it cannot be eliminated, contact the manufacturer for handling. Do not open the battery box without authorization.
For the application scenario of multi-battery parallel connection, if one battery fails needs to be replaced, ensuring that the voltage difference between the newly replaced battery pack and the other batteries that need to be connected in parallel is within 2V.
Cause if the voltage difference is large, the battery pack with high voltage will charge the battery pack with low voltage with high current, and the battery pack with low voltage will be protected by charging overcurrent, which will result in no charging and increase powerwall maintenance costs.
