Device Installation
2.1 Installation Requirements
Installation Environment
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
- 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.
No.| Cable| Type| Conductor Cross-Sectional Area Range|
Outer Diameter
---|---|---|---|---
1| Ground cable| Single-core outdoor copper-core cable| 10 mm2| –
2| DC input power cable (inverter to battery and battery to the battery)|
Common outdoor PV cable in the industry| 4-6 mm2| 5.5-9 mm
3| Signal cable (inverter to battery and battery to the battery)| Outdoor
shielded twisted pair cable (8 cores)| 0.20-1 mm2| 6.2-7 mm
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
- 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.
- 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
