High voltage may cause an electric shock, which results in serious injury, death or serious
property damage from the SUN2000 in operation. Strictly comply with the safety precautions
in this document and associated documents to operate the SUN2000.
Do not touch an energized SUN2000 because the heat sink has a high temperature.
Follow local laws and regulations when operating the SUN2000.
Maintenance and Replacement
High voltage may cause an electric shock, which results in serious injury, death or serious
property damage from the SUN2000 in operation. Prior to maintenance, power off the
SUN2000 and strictly comply with the safety precautions in this document and associated
documents to operate the SUN2000.
Maintain the SUN2000 with sufficient knowledge of this document, proper tools, and
testing equipment.
Before performing maintenance tasks, power off the SUN2000 and wait at least 15
minutes.
Temporary warning labels or fences must be placed to prevent unauthorized people

2.2 Product Introduction
Function
The SUN2000 is a grid-tied PV string inverter that converts the DC power generated by PV
strings into AC power and feeds the power into the power grid.
Features
Intelligent
Six independent maximum power point tracking (MPPT) circuits and 12 PV string inputs:
Supports the flexible configuration of 2+2+2+2+2+2 strings.
12 routes of high-precision smart PV string monitoring: Help identify and rectify
exceptions timely.
Smart I-V curve diagnosis: Implements I-V scanning and health diagnosis for PV strings.
In this way, potential risks and faults can be detected in time, improving the plant
operation & maintenance (O&M) quality.
Safe
Embedded DC and AC SPDs: all-dimensional surge protection
Embedded residual current monitoring unit: Immediately disconnects from the power
grid upon detecting that the residual current exceeds the threshold.
Reliable
Natural cooling
Free fuse design
Protected to IP65.
Effective design against ground subsidence: The AC terminal block can be pulled down
by up to 50 mm due to the pulling force.
Network Application
The SUN2000 applies to distributed grid-tied commercial PV systems and large-scale
grid-tied PV plants. Typically, a grid-tied PV system consists of the PV string, SUN2000, AC
combiner box, and step-up transformer.

Local maintenance refers to operations performed after a USB flash drive, a WLAN module, a
Bluetooth module, or a USB data cable is inserted into the USB port of the solar inverter. For
example, localmaintenance includes data import and export using a USB flash drive, and connecting
to the SUN2000 app over a WLAN module, a Bluetooth module, or a USB data cable.
If the alarming and the local maintenancehappen concurrently, the alarm/maintenance indicator
shows the local maintenance state first. After the USB flash drive, WLAN module, Bluetooth
