Installation Requirements

2.1

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

1. Install the mounting bracket.

2.2

Level

2. (Optional) Install the screw for locking the DC switch.

•M6x60 expansion bolts are delivered with the solar 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 solar inverter are mainly 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 solar inverter.

•In residential areas, do not install the solar inverter on drywalls or walls made of similar

materials which have a weak sound insulation performance because the noise generated by

the solar inverter is noticeable.

•Loosen the nut, flat washer, and spring washer of the expansion bolt at the bottom.

3. Install the solar inverter onto the mounting bracket. 4. (Optional) Install an anti-theft lock.

Prepare an anti-theft lock by yourself. The lock should be suitable for the lock hole diameter

(Ф10 mm) so that it can be installed successfully. An outdoor waterproof lock is recommended.

Preparing Cables

3.1

•To ensure that the inverter can be safely disconnected from the power grid when an

exception occurs, connect an AC switch to the AC side of the inverter. Select an appropriate

AC switch in accordance with local industry standards and regulations.

•Connect cables in accordance with the local installation laws and regulations.

•Before connecting cables, ensure that the DC switch of the solar inverter and all the switches

connected to it are set to OFF. Otherwise, the high voltage produced by the solar inverter

may cause electric shocks.

Prepare cables based on site requirements.

•Do not connect loads between the inverter and the AC switch that directly connects to the

inverter. Otherwise, the switch may trip by mistake.

•If an AC switch is used with specifications beyond local standards, regulations, or Huawei's

recommendations, the switch may fail to turn off in a timely manner in case of exceptions,

causing serious faults.

Each inverter must be equipped with an AC output switch. Multiple inverters cannot connect

to the same AC output switch.

No.

Installing the PE Cable

3.2

Ground

point

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.

•Silica gel or paint must be applied around the ground terminal after the PE cable is connected.

•It is recommended that the right ground point be used for grounding. The other ground point

is reserved.

•If FE communication is used, install a WLAN-FE Smart Dongle (SDongleA-05). You need to

purchase the WLAN-FE Smart Dongle by yourself.

•If 4G communication is used, install a 4G Smart Dongle (SDongleA-03). You need to

purchase the 4G Smart Dongle by yourself.

Installing a WLAN Antenna or Smart Dongle

Ensure that the WLAN antenna is

installed securely.

WLAN Antenna (WLAN Communication)

(Optional) WLAN-FE Smart Dongle (FE Communication)

You are advised to use a Cat 5e outdoor shielded network cable (outer diameter < 9 mm;

internal resistance ≤ 1.5 ohms/10 m) and shielded RJ45 connectors.

4G/FE

SDongleA-03

Quick Guide (4G)

•The quick guide is delivered with the Smart Dongle. You can download them by scanning

the QR code below.

WLAN-FE 4G

•Install the SIM card in the arrow direction.

•When reinstalling the cover of the Smart Dongle, ensure that the buckle springs back in

place (you can hear a click).

•If your Smart Dongle is configured with a SIM card, you do not need to install the SIM card.

The configured SIM card can be used only on the Smart Dongle.

•If your Smart Dongle is not equipped with a SIM card, prepare a standard SIM card (size: 25

mm x 15 mm) with the capacity greater than or equal to 64 KB.

(Optional) 4G Smart Dongle (4G Communication)

Installing the AC Output Power Cable

3.4

Ensure that the protective layer of the AC output power cable is inside the connector, that the

core wires are totally inserted into the cable hole, and that the cable is connected securely.

Failing to do so may cause device malfunction or damage.

1. Connect the AC output power cable to the AC connector.

Three-Core Cable (L, N, and PE)

Click

2. Connect the AC connector to the AC output port. Check the route of the AC output power cable.

AC output port (AC)

•The method for connecting a two-core AC output power cable is the same except that the

cable is not connected to PE.

•Strip the insulation layers of the AC output power cable by the recommended length (12–16

mm) to ensure that the cable conductors are completely inside the conductor insertion

points and no insulation layer is pressed into the conductor insertion points. Otherwise, the

device may fail to run properly or be damaged during operation.

Plug insert

To remove the AC connector,

perform the operations in

reverse order of installing the

AC connector. Then, remove

the plug insert, as shown in

the following figure.

Installing DC Input Power Cables

3.5

1. Ensure that the PV module output is well insulated to ground.

2. 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.

3. The DC input voltage of the solar inverter must not exceed maximum input voltage.

4. Before installing DC input power cables, label the cable polarities to ensure correct cable

connections.

5. If DC input power cables are 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 warranty. Wait until the solar irradiance declines at night and the

PV string current reduces to below 0.5 A, and then turn off the DC switch and remove the

positive and negative connectors. Correct the string polarity before reconnecting the PV string

to the solar inverter.

1. Assemble DC connectors.
