This document provides essential instructions for the installation, electrical connection, and commissioning of the Huawei SUN2000-196KTL-H3, 200KTL-H3, and 215KTL-H3 series solar inverters. It is intended for qualified electrical technicians.
Product Overview
The inverter features a front panel with status indicators (PV, Grid, Communication, Alarm/Maintenance) and a maintenance compartment. The bottom of the unit contains DC switches, reset buttons, communication ports, and cable entries.
Installation Requirements
- Environment: If installed in areas with vegetation, harden the ground with cement or gravel.
- Angle: Ensure the inverter is installed at an appropriate angle (refer to diagrams).
- Space: Maintain sufficient clearance (at least 600mm on sides, 200mm top, 600mm bottom) for ventilation and cable bending radius.
Installing the SUN2000
- Install the mounting bracket using M12 bolts (torque 45 N·m).
- Unpack the inverter and mount it onto the bracket.
- Adjust handle positions if necessary.
Installing Cables
- PE Cable: Connect to a nearby PE point.
- AC Output Power Cables: Select appropriate terminals based on cable type (copper/aluminum) and diameter. Ensure firm connections.
- DC Input Power Cables: Use MC4 EVO2 connectors. Ensure correct polarity. Do not connect individual PV strings in parallel.
- RS485 Communications Cable: Separate from power cables to prevent interference.
Powering On the System
- Turn on the AC switch between the inverter and the grid.
- Switch on DC SWITCH 1.
- Check LED1 status. If steady green, switch on DC SWITCH 2 and DC SWITCH 3.
SUN2000 App
The app allows for local monitoring and maintenance. Connect via WLAN, Bluetooth, or USB data cable. The initial login password for all user levels is 00000a. Change this password immediately upon first login.
FAQ
If a DC switch automatically turns off due to a fault, check the fault type on the app. After rectifying the fault, press the RESET button and then turn the switch back to ON.
