Follow these requirements when choosing an installation site
General guidelines and requirements
The battery may be installed in an indoor location. The battery must be secured to a wall using the supplied mounting bracket and 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. Because the battery has a natural convection, the installation site mustbe clean, dry and well ventilated. The installation location must allow easy access to the battery forinstallation and maintenance. The battery shall not be exposed to direct sun or rain.
Restricted 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 Sites at altitudes of more than 2000 meters above the sea level The battery shall not be exposed to direct sun or rain.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 moudle or any heat source, such as water heater unit, gas-fueled heater, air contitioning 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
Dimensions
Note the following dimensions:
| Width | Height | Depth | |
|---|---|---|---|
| Parallel Control Box | 600mm | 150mm | 210mm |
| Battery Module | 600mm | 440mm | 210mm |
Battery Dimensions
Residential barrier
To prevent the spread of fire, install a non-combustible barrier on the opposite side of the wall or structural surface where the battery is mounted.
If the installation surface is not made of non-combustible material, a non-combustible barrier should be placed between the battery and the wall or structural surface.
If the battery pack is mounted on a wall or within 300mm from a wall that separates the energy storage system from a residential space, ensure that the distance from other structures or objects is increased.
Install the battery
Configurations
A ‘Battery Module’ is a single battery unit, while a ‘Battery Cluster’ is a group of battery modules connected in parallel. Each cluster contains a parallel control box (LFP.6144.GM) and at least two battery modules. Clusters are expandable with additional modules as needed, supporting up to 8 modules per cluster. Up to 32 battery modules can be connected across a maximum of 4 clusters, with each cluster requiring one GM control box (i.e., 4 clusters require 4 GMs).
