4.3 Determining the Installation Position

4.3.1 Environment Requirements

Basic Requirements

 The SUN2000 is protected to IP65 and can be installed indoors or outdoors.

 Do not install the SUN2000 in a place where personnel are easy to come into contact

with its enclosure and heat sinks, because these parts are extremely hot during operation.

 Do not install the SUN2000 in areas with flammable or explosive materials.

 Do not install the SUN2000 at a place within children's reach.

 Do not install the SUN2000 outdoors in salt areas because it will be corroded there and

may cause fire. A salt area refers to the region within 500 meters from the coast or prone

to sea breeze. The regions prone to sea breeze vary depending on weather conditions

(such as typhoons and monsoons) or terrains (such as dams and hills).

 The SUN2000 must be installed in a well-ventilated environment to ensure good heat

dissipation.

 Recommended: Install the SUN2000 in a sheltered place or a place with an awning.

Mounting Structure Requirements

 The mounting structure where the SUN2000 is installed must be fireproof.

 Do not install the SUN2000 on flammable building materials.

 The SUN2000 is heavy. Ensure that the installation surface is solid enough to bear the

weight load.

 In residential areas, do not install the SUN2000 on drywalls or walls made of similar

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

by the SUN2000 is noticeable.

4.3.2 Space Requirements

Installation Angle Requirements

The SUN2000 can be wall-mounted or pole-mounted. The installation angle requirements are

as follows:

 Install the SUN2000 vertically or at a maximum back tilt of 15 degrees to facilitate heat

dissipation.

 Do not install the SUN2000 at forward tilted, excessive back tilted, side tilted,

horizontal, or upside down positions.

5.2 Connecting the PE cable

Precautions

 Ensure that the PE cable is properly connected. If it is disconnected or loose, electric

shocks may occur.

 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.

 After the ground cable is installed, it is recommended that the silica gel or paint be applied to the

ground terminal for protection.

Additional Information

The SUN2000 has the grounding detection function. This function detects whether the

SUN2000 is grounded properly before its startup, or whether the ground cable is disconnected

when the SUN2000 is running. This function works under limited conditions. To ensure the

safe operation of the SUN2000, ground the SUN2000 properly according to the connection

requirements of the PGND cable. For some power grid types, if the output side of the inverter

is connected to an isolation transformer, ensure that the inverter is properly grounded and set

isolation settings to Input not grounded, with a transformer to enable the inverter to run

properly.

 According to IEC62109, to ensure safe application in case of the ground cable is

damaged or disconnected, connect the PE cable properly before the grounding detection

function is disabled. Ensure that the PE cable meets at least one of the following

requirements.

− The PE cable is a single-core outdoor copper cable with a conductor cross-sectional

area of at least 10 mm 2.

− Use cables that have the same diameter as the AC output cable, and ground the PE

terminal on the AC connector and the ground screw on the enclosure respectively.

 In some countries and regions, additional ground cables are required for the SUN2000.

In this case, use cables that have the same diameter as the AC output cable, and ground

the PE terminal on the AC connector and the ground screw on the enclosure respectively.

5.3 Connecting the AC Output Power Cable

Precautions

A three-phase AC switch needs to be installed on the AC side of the SUN2000. To ensure that

the SUN2000 can safely disconnect itself from the power grid when an exception occurs,

select a proper overcurrent protection device in compliance with local power distribution

regulations.

Do not connect loads between the SUN2000 and the AC switch directly connected to it.

The SUN2000 is integrated with a comprehensive residual current monitoring unit. Once

detecting that the residual current exceeds the threshold, the SUN2000 immediately

disconnects itself from the power grid.

 When routing the signal cable, ensure that it is separate from the power cable and away

from interfering sources to prevent communication from being affected.

 The protection layer of the cable is in the connector. Cut off surplus core wires from the

protection layer. Ensure that the core wires are completely inserted into the cable holes,

and that the cable is securely connected.

6.2 Powering On the System

Precautions

Before turning on the AC switch between the SUN2000 and the power grid, use a multimeter

set to the AC position to check that the AC voltage is within the specified range.

Procedure

Step 1 Turn on the AC switch between the SUN2000 and the power grid.

If the DC is on and the AC is off, the SUN2000 reports a Grid Failure alarm. The SUN2000

starts normally only after the fault is automatically rectified.

Step 2 If there is a DC switch between the PV string and the inverter, turn on the DC switch.

Step 3 Set the DC SWITCH at the bottom of the SUN2000 to the ON position.

Step 4 Wait for about 1 minute, and then observe the LED indicators of the inverter to check the

running status.

 The ambient air of the PV

array is damp and the

insulation between the PV

array and the ground is

poor.

1. Check the output resistance of

the PV array to ground. If there

is a short circuit or lack of

insulation, rectify it.

2. Check that the PE cable of the

SUN2000 is correctly connected.

3. If you are sure that the

impedance is less than the

default value in a cloudy or rainy

environment, log in to the

mobile phone app, SmartLogger,

or NMS and reset the insulation

impedance protection threshold.

Context

The Italy CEI0-21 grid code requires an IPS test for the SUN2000. During the IPS test

process, the SUN2000 consecutively tests the protection thresholds and time for 10-min

overvoltage, level 1 overvoltage, level 1 undervoltage, level 1 overfrequency, and level 1

underfrequency. The SUN2000 shuts down after the IPS test starts, and it restarts after the IPS
