6In order to avoid power reduction caused by overheating, do not mount the
inverter in a location that allows long-term exposure to direct sunlight.
7The mounting method, location and surface must be suitable for the inverter's
weight and dimensions.
8If mounted in a residential area, we recommend mounting the inverter on a solid
surface. Plasterboard and similar materials are not recommended due to
audible vibrations when in use.
9Don’t put any objects on the inverter. Do not cover the inverter.
4.2 Selecting the mounting location
•Do not mount the inverter on flammable construction materials.
•Do not mount the inverter in areas where flammable materials are stored.
•Do not mount the inverter in areas where there is a risk of explosion.
1. Mount the inverter vertically or tilted backward by a maximum of 15°.
2. Never mount the inverter tilted forward or sideways.
3. Never mount the inverter horizontally.
4. Mount the inverter at eye level to make it easy to operate and to read the
display.
5. The electrical connection area must point downwards.
DANGER!
Danger to life due to fire or explosion!

14 Installation and operating instructions
4.3 Mounting the inverter with the wall bracket
CAUTION!
Risk of injury due to the heavy weight of the inverter!
•When mounting, two persons are needed, take into account that the inverter weighs
approx. 48kg.
Mounting procedures:
1Use the wall bracket as a drilling template
and mark the positions of the drill holes,
then drill 5 holes (φ10) to a depth of
55~60mm. During operation, keep the drill
vertical to the wall, and hold the drill steady
to avoid tilted holes. After cleaning the dust
from the holes, measure their net depth.
WARNING!
Risk of the inverter falling off and injuring the installer!
•Before inserting wall anchors, measure the depth and distance of the holes.
•If the measured values don’t fulfill the mounting requirement, redrill the holes.
2After drilling holes in the wall, place 5 wall anchors into the holes,, then attach
the wall bracket to the wall using the self-tapping screws and washers
delivered with the inverter.

Installation and operating instructions15
3Holding the inverter using the handles, attach the inverter onto the wall bracket
tilted slightly downwards.
4Check both sides of the inverter to ensure that it is securely in place.

16 Installation and operating instructions
5Push the inverter inwards to the limit stop and attach it to both sides of the wall
bracket using the M5 screws and washers.
To prevent possible theft, an extra safeguard is provided. The inverter can be
locked to the left side of bracket as follows.
INFORMATION
If the inverter is installed outdoors, please refer to the information below.
• Please use a padlock for outdoor installation, check the reliability of the padlock
regularly.
• Store the key carefully for possible service.

5 Electrical connection
5.1 Safety
WARNING!
Risk of injury due to electric shock!
•The inverter must be installed only by trained and authorized electricians.
•All electrical installations must be done in accordance with the National Wiring
Rules standards and local code.
CAUTION!
Risk of injury due to electric shock!
•The external protective earthing conductor is connected to the inverter’s
protective earthing terminal through an AC connector, make sure the
connection is reliable.
•When connecting, connect the AC connector first to ensure the inverter
earthing and then connect the DC inputs.
•When disconnecting, disconnect the DC inputs first and then disconnect
the AC connector.
•Do not, under any circumstances, connect the DC inputs when the AC
connector is unplugged.

18 Installation and operating instructions
5.2 System layout of units without integrated DC-switch
Local standards or codes may require that PV systems are fitted with an external
DC-switch on the DC side. The DC-switch must be able to safely disconnect the
open-circuit voltage of the PV array plus a safety reserve of 20%.
Install a DC-switch to each PV string to isolate the DC side of the inverter. We
recommend the following electrical connection:
