NOTE

Installing DC Input Power Cables

2.3

1. Usethe positive and negative metalcontacts and DCconnectors supplied with the SUN2000.

Using other models of positive and negative metalcontacts and DC connectors mayresult in

serious consequences. The caused device damage isnot covered under any warranty or service

agreement.

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

forming contacts. Crimpthe metalcold forming contacts using crimping tool H4TC0001

(Amphenol). Crimp the metal stamping forming contacts using crimping tool H4TC0002

(Amphenol). Choose the crimping tools that fitthe metalcontact types. Do not mixup the tools.

3. Before connecting DC input power cables, mark the polarities on the cables to ensure that

the cables are connected correctly. If the cables are connected incorrectly, the device may

be damaged.

4. Insert the crimped metal terminals of the positive and negative power cables into the

appropriate positive and negative connectors. Then pull the DC input power cables to ensure

that they are connected securely.

5. Connect the positive and negative connectors to the appropriate positive and negative DC

input terminals. Then pull the DC input power cables to ensure that they are connected

securely.

6. If the DC input power cables are reversely connected and the DC SWITCH is ON, do not turn

off the DC SWITCH immediately. Otherwise, the inverter may be damaged and the damage

is beyond the warranty scope. Wait until the PV string voltage reduces to the safety range

(below 60 V DC). Then, turn off the DC SWITCH, remove the positive and negative

connectors, and rectify the connection.

5Setting Monitoring Parameters

1. If no data collector is used, set the following parameters before connecting the SUN2000 to the

power grid. For the other parameter settings, see the SUN2000 (8KTL-28KTL) User Manual. If a

data collector is used, see the SmartLogger1000 User Manual for the parameter settings.

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

preset password to log in to the SUN2000 for the first time and then change the password to a

new one to ensure the account security.

4System Power-on

1. Switch on the AC circuit breaker between the SUN2000 and the power grid.

2. Ensure that the DC Switch at the bottom of the SUN2000 is ON.

3. (Optional) Measure the temperatures at the joints between the DC terminals and the connectors.

6SUN2000 APP

1. The SUN2000 app enables the SUN2000 to communicate with the monitoring system through

a USB data cable or Bluetooth for you to query alarms, configure parameters, and perform

routine maintenance. The SUN2000 app is a convenient platform for local monitoring and

maintenance. The app name is SUN2000.

2. Access the Huawei app store (http://appstore.huawei.com), Google Play

(https://play.google.com), or App Store (iOS), search for SUN2000, and download the

SUN2000 app software package.
