Installation Space

Mounting Hole Dimensions

2.2 Installing the Floor Support
DANGER
Avoid drilling holes in the water pipes and cables buried in the wall.

If holes cannot be drilled on the ground, the battery expansion modules must be secured on the wall.
NOTE

• The M6x60 expansion bolts delivered with the battery are mainly used for solid concrete walls and concrete floors. If other types of walls and floors are used, ensure that the walls and floors meet the load-bearing requirements (one battery expansion module weighs 50 kg) and select the bolts by yourself.
• The power control module (DCDC) must be fixed on the wall. If the device is installed in an area prone to earthquakes or vibration, you can mark the battery module mounting holes and drill holes to install expansion bolts in step 2.

2.3 Installing Battery Expansion Modules

1. Install the battery expansion modules and power control module on the support.

NOTICE

• The following describes how to install the battery expansion modules for a 15 kWh model.
• The installation of battery expansion modules for 5 kWh and 10 kWh models is the same. One battery expansion module is installed for a 5 kWh model, and two battery expansion modules are installed for a 10 kWh model.

Install the remaining battery modules and power module from bottom to top. After installing a module, secure the left and right connecting pieces, and then install the next module.

2. Secure the power control module to the wall.
3. (Optional) Secure the battery expansion modules to the wall by referring to step 2.

2.4 Wall-mounted Installation
Mounting Hole Dimensions

Installing the Support for Wall-mounted Installation
NOTE
For floor-mounted installation, the base is 50 mm high. If waterproofing requirements cannot be met, the battery can be installed on a wall. The mounting kits need to be purchased separately. For wall- and floor-mounted installation, ensure that the load-bearing capacity meets the requirements (one battery expansion module weighs 50 kg).

Internal Electrical Connections of the Battery

NOTICE

• Connect cables in accordance with local installation laws and regulations.
• Before connecting cables, ensure that the DC switch on the battery and all the switches connected to the battery are set to OFF. Otherwise, the high voltage of the battery may result in electric shocks.

3.1 Installing an Internal Ground Cable
3.2 Installing Internal DC Terminals
NOTE

• Internal electrical cables are delivered with the battery, see the Packing List in the packing case.
• The Amphenol terminal is used as the DC terminal between the power control module and the battery expansion modules.

3.3 Connecting Internal Signal Cables
Install the internal signal cables described in this section using the three signal cables with a diameter of 5 mm and rubber plugs delivered with the DCDC. Do not use signal cables with a diameter of 7 mm.

NOTICE

• When a communications terminal is connected to a single network cable, a waterproof rubber plug must be installed. Do not install a cable with a diameter of 5 mm into a Ф7 mm rubber plug, the 7 mm hole is used to connect to an inverter or cascaded battery.
• After inserting the terminal shell into the COM port, shake the terminal shell left and right and pull it back to ensure that it is securely installed, and tighten the nut (ensure that the rubber plug is tightly compressed). Otherwise, the waterproof performance is affected.

External Electrical Connections of the Battery

4.1 Preparing Cables
NOTICE
Connect cables in accordance with local installation laws and regulations.
NOTICE

• Before connecting cables, ensure that the DC switch on the battery and all the switches connected to the battery are set to OFF. Otherwise, the high voltage of the battery may result in electric shocks.
• The DC input power cable and signal cable between the battery and the inverter must be less than or equal to 10 m.

Prepare cables based on on-site requirements.

4.2 Routing Cables Out of the Cable Hole
NOTICE
Before connecting external cables, route the cables through the cable hole to avoid disconnecting after installation.
4.3 Installing a Ground Cable
NOTE

• Ground a ground point of the power control module.
• Apply silica gel or paint around the ground terminal after the ground cable is connected.

4.4 Installing DC Input Power Cables
NOTICE

1. You are advised to connect the battery terminals (BAT+ and BAT–) on the switch side to the inverter and connect the other side to the cascaded battery.
2. The battery terminals use the Staubli MC4 positive and negative metal terminals and DC connectors supplied with the solar inverter. Using incompatible positive and negative metal terminals and DC connectors may result in serious consequences. The caused device damage is not covered under warranty.

Assembling DC Connectors

Installing DC Input Power Cables

DANGER
Use dedicated insulated tools to connect cables. Ensure that battery cables are connected to the correct polarities. If the battery cables are reversely connected, the battery may be damaged.

4.5 Installing a Signal Cable
NOTICE

• When laying out a signal cable, separate it from power cables and keep it away from strong interference sources to prevent communication interruption.
• Ensure that the protective layer of the cable is inside the connector, that excess core wires are cut off from the protection layer, that the exposed core wire is totally inserted into the cable hole, and that the cable is connected securely.
• Use a plug to block the idle cable hole with the waterproof rubber ring, and then tighten the locking cap.
• If multiple signal cables need to be connected, ensure that the outer diameters of the signal cables are the same.

Communications Terminal Description

6pin–10pin are close to the groove side.

NOTE
It is recommended that the right side of the COM port be connected to the inverter and the left side of the COM port be connected to the cascaded batteries. The communications terminal insertion directions on the left and right sides of the COM port are different. Insert the communications terminals in the directions shown in the figures.
COM Port Pin Definitions

NOTE
The communications terminals on the inverter side need to be connected to RS485+\RS485-, EN+\EN-, and PE. The communications terminals on the cascading side need to be connected to RS485+\RS485-, EN+\EN-, CANH\CANL, and PE.

Connecting the Communications Terminal to the Inverter

4.6 (Optional) Cable Connections in Cascading Scenarios
Cascading Networking

Cascading DC Input Connection
Prepare DC connectors and connect DC battery cascading terminals (BAT+ and BAT–) for cascaded batteries. For details, see section 4.4 “Installing DC Input Power Cables“. The Staubli MC4 positive and negative metal terminals and DC connectors on the cascading side need to be purchased by customers.

Connecting the Communications Terminal for Cascaded Batteries

NOTICE
After inserting the terminal shell into the COM port, shake the terminal shell left and right and pull it back to ensure that it is securely installed, and tighten the nut (ensure that the rubber plug is tightly compressed). Otherwise, the waterproof performance is affected.
