Contents of this chapter

This chapter contains the instructions that you must follow when you select the cables,
protections, cable routing and way of operation for the inverter system.

Limitation of liability

The installation must always be designed and made according to applicable local laws and
regulations. ABB does not assume any liability whatsoever for any installation which
breaches the local laws and/or other regulations. Furthermore, if the recommendations
given by ABB are not followed, the inverter may experience problems that the warranty
does not cover.

Selecting the transformer

Transformers designed for photovoltaic applications are available from ABB. Galvanically
isolate each inverter from other inverters, and medium and low voltage networks with a
dedicated transformer or winding. If you intend to connect inverters in parallel, contact
ABB for more information. ABB recommends a transformer designed for the environment
where it will be installed, compliance with power transformer standard IEC 60076 and
testing according to converter transformer standard for industrial applications
IEC 61378-1. Obey all country-specific requirements.
