2.4 How it works
Morning Optimized self-consumption will be achieved. ESS is used to store excess energy produced by PV system.
Afternoon Extra energy will be fed into the grid when ESS is fully charged and system has already reached its self-consumption requirement.
Evening ESS will power the AC load at sunset.
Night If the ESS capacity is insufficient to meet self consumption requirement, electricitywill be obtained from the grid.
2.5 Feature
CFE-Residential ESS Lithium-ion Battery is characterized with:
Energy storageunit: This battery is suitable for PV solar systemcompatibility.
Battery management system (BMS): The battery’s built-in BMS monitor prevents the battery from running outside its design limitations. See Troubleshooting in Chapter 8.
Monitor: The battery’s BMS built-inWIFI module can help check the battery running information in themobile phone.
Expandability: The battery capacity can be increased by adding another battery of the same batch and specification.
3 Guidance for batteries during shipment

1. Cartons that have been crushed, punctured, or torn in such a way that contents are revealed shall be set aside in an  isolated area and inspected by a skilled person. If the package is deemed to be not shippable, relevant contents shall be promptly collected and segregated. Meanwhile, it is required to contact the consignor or consignee.

2. The DC circuit of Residential ESS has been disconnected before outgoing.

3. A precautionary label must be affixed to the shipping carton to alert individuals that the battery within the package has
   been disconnected; otherwise, the battery should not be transported.

4. We have conducted comprehensive tests of our equipment distributed around the world to ensure safety for shipping transport. These products shall be handled with care and immediately inspected if visibly damaged. It needs to contact with customer careline in case of any visible damage to cartons to confirmwhether the battery could be used safely or not.

Installation Prerequisites

4.1 Installation location
Make sure that the installation locationmeets 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 explosivematerials nearby.
• Optimal ambient temperature is between 15℃and 30°C.
• Temperature and humidity stay at a constant level.
• Minimal dust and dirt in the area.
• No corrosive gases present, including ammonia and acid vapor.
• The Residential ESS is rated at IP20, so the battery could be installed indoors.
• If the ambient temperature exceeds the operating range, battery will protect itself by shutting down. The optimal operating
• temperature of the battery is 15°C to 30°C. Frequent exposure to severe operating conditions would exacerbate the performance and lifetime of the battery.

4.2 Installation process
The battery should be installed according to the following flow chart. 4.3 Installationmaterials
Following installationmaterials should be prepared by installers.
Power cable

• Communication cable
• Earthwire
• Bipolar external isolators. When two or more battery systems are connected 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 battery and inverter is recommended to install, and its min. current should be over 150A or comply with local regulations.
4.4 Tools
To install the battery pack, those following tools are probably required:In order to protect the safety of operators and installers, it is necessary to select and employ suitable tools andmeasuring instruments that are certified for precision and accuracy.
4.5 Safety instruments
When dealing with the battery, following safety gears should be equipped. Installers must meet relevant requirements of IEC 60364 or domestic legislations and other relevant international standards. 4.6Communication cable If needed, the network cable should be made as shown in that diagram. But the network cable between battery and inverter shouldbe produced following the definition of inverter. If available, a LAN cable tester can be used to checkwhether the cable is faulty.
4.7 Storage
If the battery is not to be installed immediately, it should be removed from operation. It is secure and proper to be stored in an appropriate location, if long period storage is needed. Instructions for storage are:

• Do not stackmore than 8 battery boxes.
• The temperature of battery stored is recommended in the range of 0°C to 45°C.
• Do not expose to water

The ESS box should be upright and not stacked upside downwhen being stored.
If the ESS needs to be stored over 3 months, the DC circuit of battery is suggested to be disconnected. Otherwise, the battery would discharge at a minimum rate and capacity degrades with storage time. Generally, the battery self-consumption is less than 5w. And, if the battery is stored over 6months, it is suggested to connect the batterywith inverter for system commissioning.

Battery Installation

5.1 Package items
These items are included in the package. 5.2 Checks before installation
