Mounting Hole Dimensions

Installing the Floor Support

Avoid drilling holes in the water pipes and cables buried in the wall.


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 and select the bolts by yourself.

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.

1. Align the first battery expansion module with the support on the floor support.
   
2. Install the connecting pieces on both sides and tighten the four screws.
   
3. 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.

Installing the Support for Wall-mounted Installation

You need to purchase the mounting kits for wall-mounted installation by yourself.


Avoid drilling holes in the water pipes and cables buried in the wall.

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.

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.

Connecting Internal Signal Cables

External Electrical Connections of the Battery

Preparing Cables

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.

Prepare cables based on site requirements.

Routing Cables Out of the Cable Hole

Cut a cable hole based on the cabling mode, and route external cables through the cable hole.
NOTICE
Before connecting external cables, route the cables through the cable hole to avoid disconnecting after installation.

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

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

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 protection 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.

COM Port Pin Definitions
The COM port definitions on both sides of the power control module are the same. It is recommended that the COM port on the switch side be connected to the inverter and the COM port on the other side be connected to the cascaded battery.
