2. SAFETY AND WARNINGS
1. All persons who are responsible for mounting, installation, commissioning,
maintenance, tests, and service of KSOLARE inverter products must be suitably
trained and quali ed for corresponding operations. They MUST be experienced and
have knowledge of operation safety and professional methods. All installation
personnel must have knowledge of all applicable safety information, standards,
directives, and regulations.
2. The product must ONLY be connected and operated with PV arrays of protection
class II, in accordance with IEC 61730 , application class A. The PV modules must also
be compatible with this product. Power resources other than compatible PV arrays
MUST not be connected and operate with the product.
3

3. When designing or constructing a PV system, all components MUST remain in their
permitted operating ranges, and their installation requirements MUST always be
ful lled.
4. Under exposure to sunlight, the PV array may generate dangerous output in DC
voltage. C ontacts with the DC wires, conductors and live components in the inverter
may result in lethal shocks.
5. High voltages in inverter could cause lethal electrical shocks. Before proceeding any
work, including maintenance and/or service, on the inverter, fully disconnect it from
all DC input, AC grid and other voltage sources. There MUST be a 5 -minute waiting
time after the full disconnection.
6. The DC input voltage of the PV array MUST never exceed the maximum input
voltage of the inverter.
7. DO NOT touch parts of the inverter during operation as heat will be induced and
these parts will exceed 60 0.

4. 4INSTALLING
4.1 Installation Requirement
1. Please install the inverter(s) in places that can avoid inadvertent contact.
2. Installation method, location and surface must be tting for the inverter’s weight and
dimensions.
3. Please install the inverter in an accessible location for operation, future maintenance
and service.
4. The inverter performance peaks at ambient temperature lower than 450.
5. When installing in residential or domestic environment, it is recommended to install
and mount the inverter on a solid, concrete wall surface. Mounting the inverter on
composite or plaster boards or walls with similar materials would induce noise during
its operation and is therefore not recommended.
6. DO NOT cover the inverter NOR place any objects on top of the inverter.
7. To ensure su ient room for heat dissipation and maintenance, the clearing space
between inverter(s) and other surroundings is indicated below for reference:
8. Avoid direct exposure to sunlight and rain and snow layup.
No sun No Rain No Snow

4.2 Mounting Location
1. DO NOT mount the inverter near any ammab le materials.
2. DO NOT mount the inverter near any explosive materials.
3. DO NOT mount the inverter on tilting surface over 15° backwards. Please mount the
inverter on a vertical wall surface.
4. DO NOT mount the inverter on any surfaces tilting forward or to either sides.
5. DO NOT mount the i nverter on a horizontal surface.
6. For easy installation and operation, please mount the inverter on a height that the
display could match eye level.
7. The bottom side where all commissioning terminals are equipped MUST always point
downwards.
4.3 Mounting
Wall - mounting the inverter
1. Use the mounting bracket as a template and drill holes of 10mm diameter and
70mm depth.
2. Fix the mounting bracket with the screws and expansion bolts packed in mounting
accessories.
3. Hold onto the handles on the inverter and tilt it slightly forward. Hang up the invert
er
and attach it to the mounting bracket. Check both sides of the heat sink to ensure its
stably attached.
4. Observe from above, ensure the inverter has been securely attached to the bracket.
5. Use M5 screws (T25 screwdriver, torque 2.5 Nm) to attach the heat sink s to the
mounting bracket.
It is recommended to attach the anti - theft lock to the inverter. Lock diameter φ4- 5.5m m
recommended .
7

Racket - mounting the inverter:
In the same way as wall- mounting the inverter, only replace the expansion bolts and screws with
M10*45 Stainless steel full thread screw assembly (The assembly incl. bolt, nut, t washer, spring
washer is not included in the package)
4. 4 Installing the secondary PE cable
1. Insert the grounding conductor into the suitable OT terminal lug and crimp the
contact.
2. Align the terminal lug with the grounding conductor and the ground washer on the
screw. The teeth of the ground washer must be facing the housing.
3. Tighten it rmly into the housing ( M6 PE terminal, screwdriver type: Pan head ,
torque: 4.5Nm).
