1.2 Target Audience This manual is intended for anyone who uses Autarco XLX-MII series inverter. Before any further action, the operators must first read all safety regulations and be aware of the potential danger to operate high-voltage devices. Operators must also have a complete understanding of this device’s features and functions.
For example, S2.XLX25000S-MII.1 is the 20kW model with Dutch grid standard as default, integrated DC switch and Autarco blue cover. Please keep this user manual available at all times in case of emergency.
This is because photovoltaic (PV) arrays create electrical energy when exposed to light, and could cause a hazardous condition. The XLX-MII series inverter must only be operated with PV arrays of protection class II, in accordance with IEC 61730, class A.
2.3 Internal DC switch Please verify whether your Autarco XLX-MII series inverter is equipped with an internal DC switch. If there is an internal DC switch the product code will end in an “S”. The switch can be found on the bottom of the inverter (see Error! Reference source not found.).

installation and operation manual Installation 5.1 Safety DANGER! Do not install the inverter near flammable or explosive items. WARNING! The installation must be performed by qualified personnel and in compliance with national and local standards and regulations. This inverter will be connected to a high voltage DC power generator and AC grid. Inappropriate installation may also jeopardize the life span of the inverter.
5.3 Safety clearance Caution! Make sure heat sinks are out of reach of children. Observe the following minimum clearances to walls and other mounted equipment: A minimum clearance in front of the inverter of 1000mm is required for maintenance. XLX-MII series Inverters...

NOTICE! Make sure to set the correct grid standard as part of system commissioning, see chapter 7.6. The Autarco inverter is equipped with an integrated Residual Current Protective Device (RCPD) and Residual Current Operated Monitor (RCOM). The RCOM will detect the volume of the leakage current and compare it with the expected value, if the leakage current exceeds the permitted range, the RCPD will disconnect the inverter from the AC load.
