CAUTI N
If the ambient temperature is outside the operating range, the battery pack stops operating to protect
itself. The optimal temperature range for the battery pack to operate is 0°C to 45°C. Frequent exposure
to harsh temperatures may deteriorate the performance and life of the battery pack.
5.2.1.Minimum clearances
bserve the minimum clearances to walls, other batteries or objects as shown in the diagram and
picture below in order to guarantee sufficient heat dissipation

5.3.Installing the Battery Pack
5.3.1.Mounting to a wall
WARNING
In order to avoid electrical shock or other injury, inspect existing electronic or plumbing installations
before drilling holes.
The battery is heavy, please handle with care to avoid damage to the product or injury to the installer.
1.Choose suitable firm wall with thickness greater than 80mm.
2.Use the mounting frame as a template, mark the hole position.
3.Drill 8 holes according to the hole position, it is ø10 with depth 60mm.
4.Hammer the M8 screws to the above holes, and screw the nut. Note: Do not position screws
flush to the wall - leave 10 to 20 mm exposed.
5.Fix the mounting frame to the 8 screws.
6.Raise the battery a little higher than the mounting frame whilst maintaining the balance of the
battery. Hang the battery on the frame through the match hooks.
WARNING
Falling equipment can cause serious or even fatal injury: never mount the inverter on the bracket unless
you are sure that the mounting frame is firmly mounted on the wall after thorough checking.

5.4.Parallel use of attery
5.4.1.Parallel use of battery ( All off grid solar inverters )
GSL ENERGY powerwall battery is a smart battery to match all off grid solar inverter ( 48VDC) types.
When the battery needs to be used in parallel, the maximum connection is 14 units, but we recommend
2-4 units according to application. When connecting with off grid 48VDC solar inverters, it does not
need to add Canbus/RS485 communication cables with inverters, if inverter brand factory does not have
Canbus/RS485 port, just plug and play use.
NOTE: Parallel power ca le standard is 1 meter. This is not standard ca le in attery package.
For parallel ca le quantity needed, please consult with GSL ENERGY sales manager for proper
use and related quantity.

When the battery needs to be used in parallel, the maximum connection is 15 units(Can us), 14units
( RS485 ) with GSL hy rid solar inverter, but we recommend to use 2-4 units according to application.
The application needs power and communication connections as below, choose suitable parallel power
cables and related connectors.
NOTE: Parallel power standard is 1 meter. This is not standard ca le in attery package.
For parallel ca le issue, please consult related factory sales manager for proper use and related
