Introduction
Thank you for buying this Sunny Roo Series Inverter. Many years of design
experience has gone into the construction of this device, and your Sunny Roo
Series Inverter should give your solar power system many years of trouble-free
operation.
Your new Inverter is a complex electronic system, and over its life-time it will
be confronted with a variety of local conditions. If a malfunction of your Sunny
Roo Series Inverter occurs, please contact your specialised dealer directly. Your
dealer will assist you or will refer you to someone who can help with your
query.
Please read this User Manual carefully to familiarise yourself with your new
device. Please pay particular attention to information regarding the installation
and commissioning of your Sunny Roo Series Inverter.
Important Safety Instructions
General
This manual contains important instructions for the Sunny Roo Series SR
1500TL, 2000TL, 3000TL, 4200TL, 5000TL that should be followed during
installation and maintenance of the inverters.
Housing
Only qualified installers are authorised to open the connection area. Do not
open the connection area when the inverter is under load (ie. ensure power is
not running through inverter).
Only trained service staff may open the upper portion (power stage) of the SR
Series Inverter, and only when the inverter is not under load.
Repair
Only trained service staff are authorised to carry out repairs to the SR Series
Inverter unit.
Warning! Incorrect operation and/or work
performed can cause serious injury and damage!
Only qualified personnel are authorised to install
your SR Series Inverter; installation should be
carried out within the scope of the respective
technical regulations. Do not start operation or
carry out maintenance work before reading the
chapter ‘Important Safety Instructions’.
Warning! These servicing instructions are for use
by qualified personnel only. To reduce the risk of
electric shock, do not perform any servicing other
than that specified in the operating instructions
unless qualified to do so.

PV Module
Before connecting the solar modules, you must check whether the voltage
parameters specified in the manufacturer’s data correspond with the actual
parameters. When checking the voltage reading, please take into account that
solar modules supply a higher no-load voltage when temperature is low and
sunlight level remains unchanged. At 14°F (-10°C) the open-circuit voltage of
the PV modules must never exceed 500V. The data sheet of the solar module
will tell you the temperature factors applicable for determining the theoretical
open-circuit voltage at 14°F (-10°C). If the solar modules exceed an open-circuit
voltage of 500V, the SR Series Inverter may be damaged. In these circumstances all warranty rights will be void.
The SR Series Inverter includes a Residual Current Monitoring Unit (RCMU)
according to VDE0126-1-1. This device measures the Earth current of the PV
array and will prevent the inverter from feeding the grid in the case of an
Earth fault.
Grid Connection
Only appropriately licensed contractors are authorised to connect the SR
Series Inverter to the grid. Consult your local authorities for specific requirements. Before connecting the SR Series Inverter to the grid, permission for the
connection must be granted by the utility company.

Installation Requirements
The SR Series Inverter is heavy. Take this weight into
consideration when choosing the installation site and
method of installation.
To ensure proper operation and long operating life, always
position the SR Series Inverter according to the following
requirements:
(1) The SR Series Inverter is designed for
outdoor installation, and should be installed
away from direct sunlight. Increased
ambient temperatures and/or installation
in poorly ventilated and warm indoor
locations may reduce the yield of the PV
system. The optimum ambient temperature
lies within the -25°C to +50°C range.
(2) The SR Series Inverter is designed to be mounted on a vertical wall.
If installing the unit outdoors, make sure that it is not slanting forward.
We advise against installing the unit in a horizontal position.
(3) When choosing the installation site, ensure there is enough space for heat
dissipation. Under normal conditions, installers should adhere to the following
guidelines regarding space to be left clear around the inverter:
Mounting the Unit
We recommend that you use the supplied wall mounting bracket to mount
the SR Series Inverter. For vertical installation and installation on solid concrete
or block walls, be sure to take into account the weight of the inverter when
selecting the mounting materials.
If you do not want to use the supplied wall mounting bracket, refer to the
dimensions shown in the drawing above. The procedure for mounting the
inverter using the wall mounting bracket is described on the following pages.

Installation: Step by Step
Step 1. Fit the wall mounting bracket.
When marking the positions of the drill holes,
use the wall mounting bracket as a drilling
template.
Step 2. Hang the SR Series Inverter onto the wall mounting bracket using its
upper mounting plate. This ensures the inverter cannot be moved sideways.
Step 3. Check that the SR Series Inverter is positioned securely on the bracket.
