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.
