SMA Technologie AG Introduction

1 Introduction

The installation of the Sunny Boy may only be done by qualified
technicians. The installer must be approved by the utility company.
Please read the installation guide carefully before you begin with
the installation. The installation of utility interactive power sources
must be compliant with all applicable regulations of the utility
company and with all applicable regulations and standards.

The Sunny Boy 5000TL Multi-String is equipped with the SMA grid guard. This
is a type of independent disconnection device. It ensures that the Sunny Boy
5000TL Multi-String complies with the VDEW (Verband der
Elektrizitätswirtschaft – German Electricity Industry Association) regulations for
the connection and parallel operation of electrical power units to the low­voltage grid of the electricity supply company and with DIN VDE 0126 (4.99)
which is a part of these regulations.

This installation manual is intended solely for qualified electricians. Its aim is to help
install and set up SMA Sunny Boy 5000TL Multi-String inverters quickly and correctly.

For detailed information on troubleshooting and on how to use the Sunny Boy
5000TL Multi-String, including information about the different communication
options, please see the operating instructions.

The „Sunny Design“ tool will help to dimension and check the size of your strings with
respect to the inverter you intend to use. Further information about „Sunny Design“
is available at www.SMA.de.

If your Sunny Boy is equipped with a communication interface, you will find detailed
instructions for installation in the description of the communication interfaces (Piggy­Backs), which has been delivered with the device.

If you require further information, please call the Sunny Boy hotline on the following
number:

Work on the Sunny Boy with the lid removed must be carried out
by a qualified electrician. Hazardous and even lethal voltages can
be encountered within the enclosure. Before working on the Sunny
Boy with the lid removed, the AC and DC voltages MUST be
disconnected from the Sunny Boy and it must be sure that all
capacitors are discharged.

The Sunny Boy must be disconnected from the mains and
precautions must be taken to prevent the grid being reconnected.
In addition, the connections to the PV generator must be
disconnected.

with the input voltage will destroy the
Sunny Boy. Overvoltage on the DC side
can even cause dangerous explosions of
the Sunny Boys input capacitors and ex­plosions of the electrolytes coming from
the exploded capacitors.

After isolating the AC and DC voltage you must wait approx. 30
minutes for the capacitors in the Sunny Boy to discharge. Only then
is it safe to open the unit by removing the lid. You must also make
sure that no voltage is present in the device.

The electronics inside your Sunny Boy 5000TL Multi-String is
vulnerable in terms of electrostatic discharge. Be sure to be
connected to ground (e.g. the enclosure of the Sunny Boy) before
handling anything within the enclosure of the Sunny Boy.

SMA Technologie AG Requirements for the Installation

4 Requirements for the Installation

Please make sure to fulfill all conditions below before installing and commissioning
the Sunny Boy 5000TL Multi-String.

4.1 Requirements: Mounting Place

The Sunny Boy 5000TL Multi-String has a weight of 31 kg. Please
keep this in mind when selecting the place where and how to mount
the Sunny Boy 5000TL Multi-String.

The ambient temperature must be within -25 °C and +60 °C.

The Sunny Boy 5000TL Multi-String should be installed in a place

31 kg

The Sunny Boy is designed to be mounted on a vertical wall. For an optimum energy
yield and the most convenient operation, vertical installation at eye-level is
preferable. In case it is absolutely necessary to tilt the Sunny Boy to the back the
maximum angle is 45 °. If installing the unit outdoors, make sure that it is not slanting
forwards. We advise against installing the unit in a horizontal position outdoors.

where it is not exposed to direct sunlight. An increased ambient
temperature can reduce the yield of the PV system.

It is not reccomended to install the Sunny Boy lying on the back side with the lid facing
upwards.

max. 45°

Install the Sunny Boy vertically, or if
necessary tilted slightly to the back.

Installation Guide SB5000TL-12:SE2006 Page 13

Never install the Sunny Boy

tilted to the front.
