Installation Prerequisites

Installation location
Make sure that the installation location meets the following conditions:

• The building is designed to withstand earthquakes.
• Far away from the sea to avoid salt water and humidity.
• The floor is flat and level.
• No flammable or explosive materials nearby.
• Optimal ambient temperature is between 15℃ and 30°C.
• Temperature and humidity stays at a constant level.
• Minimal dust and dirt in the area.
• No corrosive gases present, including ammonia and acid vapor.

The CFE Residential ESS is rated at IP20, so the battery could be installed indoor.
If the ambient temperature is outside the operating range, battery will protect itself by shutting down. The battery optimal operate temperature is 15°C to 30°C. Frequent exposure to severe operating condition would exacerbate the performance and lifetime of the battery.

Installation process
The battery should be installed according to the following flow chart.

Installation materials
Following installation materials should be prepared by installers.

• Power cable
• Data cable
• Ground wire
• Bipolar external isolator, when two or more battery systems in parallel, each of them shall have a bipolar isolator.

NOTICE

• Make sure that the cross-sectional area of charging cables is 25 to 35 mm2
• A breaker between CFE battery and inverter was recommended to install, and the breaker’s min. current should be over 150A or following with local regulations.

Tools
To install the battery pack, those following tools are probably required:

In order to protect operator and installer’s safety, please select and use suitable tools and measuring instruments that are certified for precision and accuracy.

Safety instruments
When dealing with the battery, following safety gears should be equipped. Installers must meet the relevant requirements of IEC 60364 or the domestic legislation and other relevant international standards.

Network cable

If needed, the network cable should be made like that diagram. But the network cable between battery and Inverter should be made following the definition of Inverter. If available, use a LAN cable tester to check whether the cable is faulty.

Storage
If the battery is not to be installed immediately, or removed from operation and needs to be stored for a long period, please choose an appropriate location to store it. Instructions for storage are:
