Description
Ultra Thin 90MM Slimline Powerwall Battery is a tesla powerwall alternative solar battery. It is rechargeable home battery system that is installed with 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, solar recharges powerwall battery so you have a cycle of clean, renewable energy.

FAQ
How many working modes and statuses of powerwall have?
There are 4 working modes and statuses of powerwall BMS, charging mode, discharging mode, standby mode, and sleep mode.
1.1 What is the charging 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.
1.2 What is the discharging 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.
1.3 What is standby mode?
When the charging mode and discharging mode are not met, the bms battery management system enters standby mode.
1.4 What is sleep 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.
How to install the home energy storage system with bms correctly?
- Unpacking before installation, checking the number of accessories, and the appearance of batteries.
- Install the wall-mounted bracket and measure the battery voltage. Generally, the factory voltage of the battery is between 50.4V-53.5V(20%-60%)
- Remember to wear protective gloves during battery connection. When using metal tools such as torque wrench, pack the metal tools in insulation, so as to avoid the battery short circuit caused by both ends of metal tools, such as torque wrench touching the positive and negative terminals of the battery at the same time.
- Before connecting with external equipment, make the equipment in a disconnected state, and check again whether the continuous polarity and total voltage of the battery are correct. Then connect the positive electrode of the battery to the positive electrode of the equipment and the negative electrode of the battery to the negative terminal of the equipment, and fasten the connecting line.
How to maintain and inspect when the power wall battery malfunctions?
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 restated. If it cannot be eliminated, contact the manufacturer for handling. Do not open the battery box without authorization.
How to safely replace one of the failed batteries with all parallel connected batteries?
For the application scenario of multi-battery parallel connection, if one battery fails needs to be replaced, ensure 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.
