Selecting and Preparing the Installation Site
Make sure to observe the following requirements, when selecting an installation site.
Configurations

The term Battery module refers to a single battery. The term Battery Tower or Tower
refers to a number of modules stacked on top of each other and connected in parallel.
The term Battery pack or Battery refers to all the battery modules connected to each
other and to the same inverter, in one or two towers.
Connect up to 5 battery modules in two towers (maximum 3 in a tower).

10 Selecting and Preparing the Installation Site

Figure 1: Battery Pack Configurations
General Guidelines and Requirements
The battery may be installed in an outdoor or indoor location.
Since the battery must be secured to a wall using the supplied mounting bracket,
the installation location must be adjacent to a wall.
When installed indoors, the battery must not be obstructed by any building
structure, room furniture or equipment.
The battery shall not be exposed to direct sun or rain.
Since the battery has natural convection, the installation site must be clean, dry and
well ventilated.
The installation location must allow easy access to the battery for installation and
maintenance.
The front panel or battery module should not be covered.

Restricted Locations
Do not install the battery at any of following locations:
residential rooms
wall or ceiling niches
entrance/exit areas or below a staircase/passage
environments with humidity and condensed water level of over 90%
earthquake zones where additional safety measures are required
Selecting and Preparing the Installation Site11

sites at altitudes of more than 2000 meters above the sea level
sites exposed to direct sunlight or sites where the ambient temperature may exceed
the specified maximum temperatures
near flammable materials or gases or explosive environments

Clearance
Observe the following minimum clearance:
20 cm from all sides of the battery module.
30 cm from another battery module or any heat source, such as water heater unit,
gas-fueled heater, air conditioning unit or any other equipment
100 cm from emergency exits
30 cm from doors
25 cm from windows
20 cm from air vents
20 cm from other devices
WARNING!

Residential Barrier
In order to prevent a fire from spreading, install a non-combustible barrier on the other
side of the wall or structural surface, on which the battery is installed. If the installation
surface is not made of a non-combustible material, a non-combustible barrier can be
installed between the battery and the wall or structural surface.

If the Battery pack is installed on a wall or at a distance of 300mm from the wall that
isolates the energy storage system from a residential space, the distance from other
structures or objects must be increased.

Installation procedure
1. Install a floor stand.
Floor stand is optional, however, for durable and robust insulation, SolarEdge
recommends to install the battery modules on top of a floor stand, to be purchased
seperately from SolarEdge. Depending on wall leveling, consider when installing
more than one module.
a. Place the floor stand at a distance of 3-5cm from the wall.
Figure 4: Floor stand placement
NOTE
The arrow should point at the battery module front.
b. To level the floor stand, adjust each of the four legs by turning the screw using a
flat screwdriver.
Figure 5: Floor stand leveling
c. When the floor stand is balanced, tighten the nut with an open wrench in order
to secure the leg's height, then tap it.

Figure 6: Floor stand—tightening the nut
CAUTION!
Before moving the battery module to its location, make sure that both
the CB switch and the power button (soft switch) of the battery module
are off – refer to Connecting a Single Battery Module on page 20.
2. Take the battery module out of the box, move it to the installation location. You can
use the battery handles located at the top of the battery for convenience of moving
and placing it on the the right position.
3. Place the battery module on the floor stand using the top handles. Make sure that
the battery stands firmly, and not shaky, on the floor stand.
Figure 7: Top handles

4. Put the bracket on the wall, mark the drilling holes location, then remove the bracket
and drill holes in the wall.
Figure 8: Drilling the holes for the wall bracket
NOTE
Don’t drill through the bracket.
5. Assemble the supplied mounting bracket to the battery module using two M5
screws. Tighten the screws to a torque of 2.5Nm.
NOTE
For better cable routing, use the mounting bracket oval hole in a way to
enable the maximum available distance between the battery module and the
wall.
Figure 9: Setting the distance from the wall
6. Secure the battery module to the wall with screws and wall plugs. When using only
two screws, make sure to use the two outer screws diagonally as shown on the
figure below.

7. When installing battery modules in a tower configuration (one on top of the other):
Before securing the wall brackets, make sure the battery modules are aligned
(see the figure below).
Secure all battery modules to the wall as described above.
Note that the maximum allowed amount of battery modules in a tower is three.
