Moving an Inverter




Dimensions




Two M6 screw holes are reserved on both left and right sides of the inverter for installing an awning.

2.2 Installing the Inverter


When drilling holes, avoid the water pipes and power cables buried in the wall.

1. Install the mounting bracket.


• M6x60 expansion bolts are delivered with the inverter. If the length and number of the bolts do
not meet installation requirements, prepare M6 stainless steel expansion bolts by yourself.
• The expansion bolts delivered with the inverter are used for solid concrete walls. For other types
of walls, prepare bolts by yourself and ensure that the wall meets the load bearing requirements
of the inverter.
• Loosen the nuts, flat washers, and spring washers of the two expansion bolts.




2. Install the inverter on the mounting bracket. 3. (Optional) Install an anti-
theft lock.




Prepare an anti-theft lock suitable for the lock hole diameter (Ф8 mm) and ensure that the lock can
be installed successfully. An outdoor waterproof lock is recommended.


3 Electrical Connections
3.1 Preparing for Installation

3
• Connect cables in accordance with the local installation laws and regulations.
• Before connecting cables, ensure that the DC switch on the inverter and all the switches
connecting to the inverter are set to OFF. Otherwise, the high voltage of the inverter may result
in electric shocks.

3.2 Installing the PE Cable


Do not connect the neutral wire to the enclosure as a PE cable. Otherwise, electric shocks may occur.




• The PE point at the AC output port
is used only as a PE equipotential
point, and cannot substitute for
the PE point on the enclosure.
• It is recommended that silica gel
or paint be used around the
ground terminal after the PE cable
is connected.

3.3 Installing the AC Output Power Cable


• Ensure that the protection layer of the AC output power cable is inside the connector, the core
wires are totally inserted into the cable hole, and the cable is connected securely. Failing to do
so may cause device malfunction or damage.
• The hex key is delivered with the inverter and bound to the hanging kit at the bottom of the
inverter.

3. Check the route of the AC output power cable.




3.4 Installing the DC Input Power Cable


1. Use the Amphenol Helios H4 PV connectors supplied with the inverter. If the PV connectors are
lost or damaged, purchase the connectors of the same model. The device damage caused by
incompatible PV connectors is not covered under any warranty.
2. Crimp the metal stamping forming contacts using crimping tool H4TC0003 (Amphenol,
recommended) or H4TC0002 (Amphenol).
3. Ensure that the PV module output is well insulated to ground.
4. The DC input voltage of the inverter shall not exceed 1080 V DC under any circumstance.
5. Before installing the DC input power cable, label the cable polarities to ensure correct cable
connections.
6. If the DC input power cable is reversely connected, do not operate the DC switch as well as
positive and negative connectors immediately. Failing to do so may cause device damage, which
is not covered under any warranty. Wait until the night when solar irradiance declines and the PV
string current drops to below 0.5 A. Then set the DC switch to the OFF position, remove the
positive and negative connectors, and correct the polarities of the DC input power cable.

3.5 (Optional) Installing the Smart Dongle


• If you prepared a Smart Dongle without a SIM card, you need to prepare a standard SIM card (size:
25 mm x 15 mm) with the capacity greater than or equal to 64 KB.
• When installing the SIM card, determine its installation direction based on the silk screen and arrow
on the card slot.
• Press the SIM card in place to lock it, indicating that the SIM card is correctly installed.
• When removing the SIM card, push it inwards to eject it.

3.6 (Optional) Installing the Signal Cable

Communications Port Pin Definition
• Not all inverter models are delivered with the
signal cable connector.
• When laying out the signal cable, separate it
from the power cable and keep it away from
strong interference sources to avoid strong
communication interference.
• Ensure that the protection layer of the cable is
inside the connector, surplus core wires are
cut off from the protection layer, the exposed
core wire is totally inserted into the cable hole,
and that the cable is connected securely.
• If the Smart Dongle is configured, you are
advised to install the Smart Dongle before
connecting the signal cable.

Smart Dongle Networking Scenario




• In the Smart Dongle networking scenario, the SmartLogger1000A cannot be connected.
• The Smart Power Sensor is necessary for export limitation. Only the DTSU666-H Smart Power
Sensor (provided by Huawei) can be used.


SmartLogger1000A Networking Scenario




• In the SmartLogger1000A networking scenario, the Smart Dongle cannot be connected.
• A maximum of 80 devices can connect to a single SmartLogger1000A, such as inverters, Smart
Power sensor, and EMI. You are advised to connect fewer than 30 devices to each RS485 route.
• The Smart Power Sensor is necessary for export limitation. Select the Smart Power Sensor
according to the actual project.
• To ensure the system response speed, the Smart Power Sensor is recommended to be
connected to a COM port separately from inverter COM port.
