Solplanet ASW75K-LT Solar Inverter Installation Guide

GENERAL INFORMATION

This quick installation guide does not replace the description in the user manual.
The contents of this guide may be updated or revised due to product development.
The information in this guide is subject to change without notice. The latest version of this document and the manual for installation, commissioning, configuration and decommissioning are to be found in PDF format at www.solplanet.net.

SAFETY

Intended use

The product is a transformerless PV inverter which converts the direct current of the
PV generator into grid-compatible three-phase alternating current and then feeds the three-phase alternating current into the public power grid.
The product is intended for indoor and outdoor applications.
The product must only be connected with PV modules of protection class II (in accordance with IEC 61730, application class A). PV modules with a high capacitance to ground must only be used if their capacity does not exceed 5μF. Do not connect any sources of energy other than PV modules to the product.
The product is not equipped with an integrated transformer and therefore has no galvanic isolation. The product must not be operated with PV modules which require functional grounding of either the positive or negative PV conductors. This can cause
the product to be irreparablyy damaged. The product may be operated with PV modules with frames that require protective earthing.
All components must remain within their permitted operating ranges and their installation requirements at all times.
Use the product only in accordance with the information provided in the user manual and with the locally applicable standards and directives. Any other application may cause personal injury or damage to property.

The product must only be used in countries for which it is approved by Solplanet and the grid operator.
The type label must be permanently attached to the product and must be in a legible condition.
This document does not replace any regional, state, provincial, federal or national laws, regulations or standards that apply to the installation, electrical safety and use of the product.

Important safety instructions

The product has been designed and tested strictly according to the international safety requirements. As with all electrical or electronical devices, there are residual risks despite careful construction. To prevent personal injury and property damage and to ensure long-term operation of the product, read this section carefully and observe all safety information at all times.

DANGER

Danger to life due to high voltages of the PV array！
When exposed to sunlight, the PV array generates dangerous DC voltage which is present in the DC conductors and the live components of the product. Touching the DC conductors or the live components can cause to lethal electric shocks. If you disconnect the DC connectors from the product under load, an electric arc may occur leading to electric shock and burns.

Do not touch non-insulated cable ends.
Do not touch the DC conductors.
Do not touch any live components of the product.
Do not open the product.
All work on the product must only be carried out by qualified personnel who have read and fully understood all safety information contained in this document and the user manual.
Disconnect the product from voltage and energy sources and ensure it cannot be reconnected before working on the product.
Wear suitable personal protective equipment for all work on the product

DANGER

Danger to life due to electric shock when touching live system components in case of a ground fault！
If a ground fault occurs, parts of the system may still be live. Touching live parts and cables may result in death or lethal injuries due to electric shock.

Disconnect the product from voltage and energy sources and ensure it cannot be reconnected before working on the device.
Only touch the cables of the PV modules on their insulation.
Do not touch any parts of the substructure or frame of the PV array.
Do not connect PV strings with ground faults to the product.
