NOTE

1. Do not use solid conductor hard cables.

2. 3-core outdoor cables (L1, L2, L3) are configured for the SUN2000-24.5KTL/28KTL.

The table lists only the recommended cable specifications. For more information about cable

specifications, see the User Manual.

1. It is recommended that the ground cable be connected to a nearby ground position.

2. To enhance the corrosion resistance performance of the PE terminals, apply silica gel on them

after connecting the ground cable.

1. Use the positive and negative metal contacts and DC connectors supplied with the SUN2000.

Using other models of positive and negative metal contacts and DC connectors may result in

serious consequences. The caused device damage is not covered under any warranty or

service agreement.

2. The metal contacts supplied with the DC connectors are either cold forming contacts or

stamping forming contacts. Crimp the metal cold forming contacts using crimping tool

UTXTC0005 (Amphenol, recommended) or H4TC0001 (Amphenol). Crimp the metal stamping

forming contacts using crimping tool H4TC0003 (Amphenol, recommended) or H4TC0002

(Amphenol). Choose the crimping tools that fit the metal contacts.

3. Before connecting DC input power cables, label the cable polarities to ensure correct cable

connections. If the cables are connected incorrectly, the inverter may be damaged.

4. Pull back the DC input power cables to check whether the cables would be disconnected.

5. If DC input power cables are reversely connected and the DC switch is ON, do not turn off the

DC switch immediately. Otherwise, the equipment may be damaged. You can disconnect the

DC input power cable on the PV string side or wait until the PV string voltage reduces to a value

within the safety range. Then, turn off the DC switch, remove the positive and negative

connectors, and rectify the connection.

SUN2000 App

1. The SUN2000 app is a mobile phone app that communicates with the SUN2000 monitoring

system over a USB data cable, a Bluetooth module, or a WLAN module. As a convenient local

monitoring and maintenance platform, it supports alarm query, parameter settings, and routine

maintenance. The app name is SUN2000.

2. Access the Huawei App Store (http://appstore.huawei.com) or Google Play

(https://play.google.com), search for SUN2000, and download the app software package.

3. Connect a USB data cable, a Bluetooth module, or a WLAN module to the USB port of the

SUN2000 to implement the communication between the SUN2000 and the app.

NOTE

2. The preset password for Common User, Advanced User, and Special User is 000001. Use

the initial password upon first power-on and change it immediately after login. To ensure

account security, change the password periodically and keep the new password in mind. Not

changing the initial password may cause password disclosure. A password left unchanged for a

long period of time may be stolen or cracked. If a password is lost, devices cannot be accessed.

In these cases, the user is liable for any loss caused to the PV plant.
