Transformers and autotransformers for solar inverters
Transformers and autotransformers for solar inverters
This document provides technical specifications and guidelines for the use of transformers and autotransformers in solar installations, specifically for solar inverters used in generation and self-consumption applications. The focus is on optimizing profitability through low-loss equipment and ensuring inverter protection with reduced inrush.
Specifications
The document outlines the specifications for the Serie TTF transformers and autotransformers, which are designed for solar installations. Key features include:
- Input current: 800V
- Output current: 400V
- Connection group: YNyn0 for transformers, YN0 for autotransformers
- IP ratings: TTFX IP00, TTFW IP23, TTFZ IP65, AUTFX IP00, AUTFW IP23, AUTFZ IP65
Technical Guidelines
The document references the GUIDE-BT-40 for LV generator installations, emphasizing the need for galvanic separation between the network and generating facilities. While transformers are traditionally used for this purpose, autotransformers can be employed to adapt inverter output voltage to user requirements.
Product Range
The document lists a comprehensive range of transformers and autotransformers with varying power ratings (kVA), dimensions, and weights. This range allows for tailored solutions to meet specific installation needs.
Additional Features
There is a possibility of manufacturing special equipment with other voltages or ratings to suit unique project requirements. The document also mentions auxiliary equipment such as reactors for harmonic filtering and single-phase neutral generating transformers.

In the GUIDE-BT-40 of LV generator installations, some general rules of application are established for all electric power generator installations. However, and due to the rise of photovoltaic solar installations and their penetration in MV and LV networks, we find how the GUIDE particularizes these facilities. The current legislation established that there must be a galvanic separation between the network and the generating facilities, either by means of transformers or any other equivalent means, which fulfill the same functions. Due to technological development, today a large part of the manufacturers...
