2.1 Location Requirements
The inverter with IP65 can be installed indoors or outdoors.
Selecting an optimal location for the inverter is critical for its operating safety as
well as the expected efficiency and service life. Considerations for the location
include:
1. The structure should be capable of withstanding a force of four times the
weight of the inverter and be suitable for the dimensions of the inverter.
2. Install the inverter where it is convenient for installation, cable connection
and service.
3. Do not install the inverter in the living area or bedrooms. The noise
during its operation may affect daily life.
4. The location should be not accessible to children.
5. The ambient temperature and relative humidity should meet the following
requirements.
Max.
+60°C Min.
-25°C
Max. RH
+100%
6. Only mount the inverter on a non-flammable surface or a wooden
structure. Keep away from flammable materials or gas. Do not enclose
the inverter into a tight confinement.

7. Prevent the inverter from direct exposure to sun, rain and snow.
8. Install at eye level for easy
inspection.
9. Install vertically for good heat
dissipation.
10. Never install the inverter horizontally, or with a forward tilt or with a
backward tilt or even with upside down. The horizontal installation can
result in damage to the inverter.
Forward tilt Backward tilt Horizontally Upside down
11. Refer to the following figure for the clearance requirements. For
multi-row installation, the distance between two adjacent rows should be
at least 400 mm.

1. Align the wall mounting bracket
horizontally on the wall with the
arrow upwards. Mark the
position of the drill holes. Use
at least one hole on the right-
and left-hand side of the wall
mounting bracket.
Tip: When mounting on a post,
use the upper and lower central
holes of the wall mounting
bracket.
2. Set the wall mounting bracket aside and drill the marked holes. The
depth of the holes should be about 70 mm. Install the wall-mounting
bracket.

4. To protect the inverter from
theft, you can lock it with a
padlock. The padlock is
purchased by the user if
necessary. The hole diameter
is about 8 mm.
5. Remove the waterproof lid
from RS485 terminal and
install the communication
module to the inverter. Refer
to the manual delivered with
the module for details.
2.3 Installing the Energy Meter
The SUNGROW Energy Meter should be installed between the grid and the
load. It supports a 35 mm DIN-rail installation, as shown in the following figure.
