Installation and operation manual
1 Introduction
1.1 Read this first
This manual contains important information for use during installation and maintenance of the OX
series Autarco inverter.
To reduce the risk of electrical shock, and to ensure the safe installation and operation of the OX
series Autarco inverters, the following safety symbols appear throughout this document to
indicate dangerous conditions and important safety instructions.
WARNING! Indicates safety instructions, which if not correctly followed, could result
in injury, death or property damages.
Indicates important safety instructions, which if not correctly followed, could result
in damage to or the destruction of the inverter.
RISK OF ELECTRIC SHOCK! Indicates important safety instructions, which if not
correctly followed, could result in electric shock.
HOT SURFACE! Indicates safety instructions, which if not correctly followed, could
result in burns.
1.2 Target Audience
This manual is intended for anyone who uses Autarco OX 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.
ATTENTION! Qualified personnel means a person with valid license from the local
authority in:
●Installing electrical equipment and PV power systems (up to 1000 V)
●Applying all applicable installation codes and using Personal Protective
Equipment
●Analyzing and reducing the hazards involved in performing electrical work
M-S2-OX-EN-V2.4 5

WARNING! Do not use this product unless it has been successfully installed by qualified
personnel in accordance with the instructions in chapter 5 Installation.
1.3 Product versions covered by this document
The main purpose of this user manual is to provide instructions and detailed procedures for
installing, operating, maintaining, and troubleshooting the OX series of Autarco inverters which
includes the following models:
●S2.OX80000(S)
●S2.OX100000(S)
●S2.OX110000(S)
●S2.OX110000-HV(S)
The “S2.” In the product code means the product is a grid-tied inverter.
The item code or SKU will include an additional number at the end. The final number references
the default grid standard and colour of inverter. For example, S2.OX80000S.1 is the 80kW model
with Dutch grid standard as default and Autarco blue cover.
If the product has an “S” at the end it comes with integrated DC switches.
The HV version of the inverter is meant for direct connection to a transformer or industrial
installation with the appropriate voltage. The AC-connections in these inverters are 3-phase and
ground.
The product is also possible with Anti-PID functionality. However this is not necessary if used with
Autarco’s solar modules which are anti-PID-resistant.
Please keep this user manual available at all times in case of emergency.

2 Preparation
2.1 Safety instructions
DANGER! Do not touch any internal components whilst the inverter is in operation.
DANGER! Do not stand close to the inverter during severe weather conditions such as
lighting, etc.
DANGER! Make sure you completely cover the surface of all PV arrays with opaque
(dark) material before wiring them or make sure the DC circuit breaker or equivalent
DC isolator is disconnected. This is because photovoltaic (PV) arrays create electrical
energy when exposed to light, and could cause a hazardous condition.
WARNING! The OX series inverter must only be operated with PV arrays of protection
class II, in accordance with IEC 61730, class A.
WARNING! The PV inverter will become hot during operation; please don’t touch the
heat sink or peripheral surface during or shortly after operation.
NOTICE! Do not directly connect AC output of the inverter to any private AC
equipment. The PV inverter is designed to feed AC power directly into the public utility
power grid.
NOTICE! The MC4 connectors supplied in the box with the inverter are to be used to
make the connections with the inverter (Staubli MC4M-PV-KST4-6II-UR /
MC4F-PV-KST4-6II-UR).
WARNING! The installation, service, recycling and disposal of the inverters must be
performed by qualified personnel in compliance with national and local standards
and regulations. Please contact your dealer to get the information of authorized
repair facilities for any maintenance or repairmen.
Any unauthorized actions including modification of product functionality of any form will affect the
validation of warranty service; Autarco may deny the obligation of warranty service accordingly.

2.3 Internal DC switch
Please verify whether your Autarco OX series inverter is equipped with internal DC switches. This
switch can be found on the bottom of the inverter. If there isn’t an internal DC switch it is
important to apply an external DC switch in order to completely disconnect the solar PV module
strings from the inverter.

DANGER - HIGH ELECTRIC VOLTAGE
This device is directly connected to public grid. All work to the inverter
shall be carried out by qualified personnel only. There might be residual
currents in inverter for up to 10 minutes because of large capacitors.
ATTENTION
This device is directly connected to electricity DC generators and the
public AC grid.
DANGER – HOT SURFACES
The components inside the inverter will get hot during operation, DO
NOT touch aluminum housing during operating.
ATTENTION
In case of any work to the inverter, always refer to this manual for
detailed product information.

4Handling
4.1 Product handling
Instructions for handling the inverter:
1. The red circles denote cut outs on the product package. Push the cut outs to form handles
for moving the inverter.
2. Open the carton, then two people handle both sides of the inverter through the area
denoted dotted line.
Due to the weight of the inverter, bruises or bone fractures could occur when
incorrectly lifting and mounting the inverter. When mounting the inverter, take
the weight of the inverter into consideration. Use a suitable lifting technique
when mounting.

5 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.
The installation site must have good ventilation conditions. Direct exposure to
intense sunshine is not recommended.
5.2 Appropriate mounting location
The heat sink can reach a temperature of 75⁰C under operation.
Location and environmental requirements:
●Make sure the mounting wall is strong enough to hold the weight of the inverter.
●The ambient temperature of the installation site should be between -25 ⁰C and +60 ⁰C.
●Make sure of sufficient ventilation at installation site; insufficient ventilation may reduce
the performance of the electronic components inside the inverter and shorten the lifespan
of the inverter.
●The inverter has fans that will intelligently cool the inverter if the internal components
exceed 100⁰C. The fan noise can exceed 50dB; installation is not recommended in public
areas.
