2. Unit description

2.1. Overview

The basic purpose of an inverter is to convert the direct current generated by the PV array into alternating current
to feed into the electricity grid.
These units are single-phase PV inverters with a high frequency transformer, which therefore provide galvanic
insulation between the panel and the electricity grid, grounding the PV panel at either positive or negative
terminals. There are technology types for panels in which the manufacturer indicates that it is advisable to ground
one pole of the panel to prolong its useful life. Likewise, the regulations of certain countries require galvanic
insulation between the electricity grid and the PV array. This inverter is suitable for these conditions.
It includes a power conversion stage with a high frequency transformer, with which its weight and size decrease
considerably compared to conventional transformers. At the same time, the use of a high frequency transformer
substantially improves the performance of the unit.
As standard the inverter includes communication via USB, an SD card reader for updating the firmware, a
potential-free relay for signaling and two digital inputs.

2.2. Optional accessories

These units may include the following accessories:
• Communications accessories.
• Digital input card.
• Self-consumption kit.
Communication accessories
As standard these units have local communication via USB. In addition there is the option of establishing
connections using other technology types:
• RS-485.
• Ethernet (including communication via RS-485, for optional use).
• Ethernet TCP (including communication via RS-485, for optional use).
• GSM/GPRS (including communication via RS-485, for optional use).
• Bluetooth.
• Bluetooth (including communication via RS-485, for optional use).
The instructions for installing the communications accessories are indicated throughout this manual. For more
information on their functioning, consult the corresponding communication accessories manual.
Digital input cards
In certain countries this card is necessary to comply with their regulations.
Self-consumption kit
These inverters are compatible with all the self-consumption options offered by Ingeteam.

2.3. Electrical safety

The design values for electrical safety can be found below.

2.3.1. Overvoltage category (OVC)

The design of the unit complies with the regulations IEC 62109-1 and IEC 62109-2. The direct current circuits
have been designed with an overvoltage category II (OVC II), and the alternating current circuits with an overvoltage
category III (OVC III).

2.4. Contamination class

The units comply with pollution class 2, as required for this type of inverter.
