Page 35: Working Principles
2.4 Working Principles 2.4.1 Conceptual Diagram The SUN2000 receives inputs from 12 PV strings. The inputs are grouped into 6 MPPT circuits inside the SUN2000 to track the maximum power point of the PV strings. The DC power is then converted into three-phase AC power through an inverter circuit.
Page 36 Operating In Operating mode: ● The SUN2000 converts DC power from PV strings into AC power and feeds the power to the power grid. ● The SUN2000 tracks the maximum power point to maximize the PV string output.
Page 37: Storage
SUN2000-100KTL-US User Manual 3 Storage Storage The following requirements should be met when the SUN2000 needs to be stored prior to installation: ● Do not remove the packing materials, and check the packing materials regularly (recommended: every three months). If any rodent bites are found, replace the packing materials immediately.
Page 38 Figure 3-2 Maximum number of pile-up layers allowed ● If the solar inverter has been stored for more than two years, it must be checked and tested by professionals before being put into use. Issue 08 (2023-12-20) Copyright © Huawei Technologies Co., Ltd.

Page 41: Determining The Installation Position
The SUN2000 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 the voltage is high and these parts are extremely hot during operation.
Page 42 Ensure that the installation surface is solid enough to bear the weight load. ● In residential areas, do not install the SUN2000 on dry wall or walls made of similar materials which have a weak sound insulation performance because the noises generated by the SUN2000 are noticeable.
Page 43 The SUN2000 can be support-mounted or wall-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.
Page 44 Figure 4-5 Installation space requirements (back-to-back installation) NO TE For ease of installing the SUN2000 on the mounting bracket, connecting cables to the bottom of the SUN2000, and maintaining the SUN2000 in future, it is recommended that the bottom clearance be from 600 mm (23.62 in.) to 730 mm (28.74 in.). If you have any questions about the clearances, consult the local technical support engineers.
