4. System Installation

4.1 Inspections Before Installation

Outer Package Inspection: Before opening, check for any visible damage (holes, cracks) on the outer package. Verify the product model. If any abnormalities are found, do not open the package and contact customer support immediately.

Deliverables Inspection: After opening, check if all items are complete and free from external damage. If any items are missing or damaged, please contact customer support.

4.2 Preparation of Tools and Meters

Ensure you have the following tools and personal protective equipment:

• Installation tools: Screwdrivers, wrenches, pliers, wire strippers, crimping tools.
• Personal protective equipment: Protective gloves, safety goggles, safety shoes.

4.3 Selection of Installation Location

Basic Requirements:

• Do not install in areas with flammable or explosive materials.
• Avoid areas with salt damage (within 500m of shore or affected by sea breezes).
• Keep out of reach of children.
• The energy storage unit cannot be installed forwardly, horizontally, inversely, backwardly, or sideways.
• Wear goggles and protective gloves when drilling holes. Shield the device to prevent debris.
• Be prepared to bear heavy loads when handling to avoid injury.

Installation Space Requirements (Floor Mount):

• Place the battery on a firm, flat surface with a solid wall.
• Maintain a distance of 150-300mm between batteries.
• Maintain a distance of 200-500mm between the battery and the inverter.

4.4 Electrical Connection

Before making any electrical connections, ensure the energy storage switches are in the "OFF" state to prevent electric shock. All electrical connections must be performed by professional electrical technicians wearing personal protective equipment.

Preparation of Cables:

Connecting Signal Line (Single Battery Module): The signal line connects the RS485-Inverter interface of the battery module to the inverter. The communication port of some brand inverters needs to be connected to the RS485-2 interface.

When connecting the inverter, ensure the communication line is properly connected and the communication protocol is consistent. If using a standard network cable, cut off pins 1 and 2 for connection.

Energy Storage Battery Module Address Setting (Single Battery): When using a single battery, set the address to 0. Some inverters may require it to be set to 1.

Connecting Power Cord:

• For two batteries in parallel, connect the power cord of each battery.
• For multiple batteries in parallel, a bus bar is required.

Connecting Signal Line (Multiple Batteries): If multiple batteries are used, connect the communication line of each battery. Battery-to-battery connection uses the RS485-Battery interface, and battery-to-inverter connection uses the RS485-Inverter interface. The parallel status can be observed via the upper computer software (contact manufacturer for software).

Energy Storage Battery Module Address Setting (Multiple Batteries): If multiple energy storage battery modules are used in parallel, each module needs a unique address from 0 to 14. Addresses cannot be repeated.
