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 qualified 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. When designing or constructing a PV system, all components MUST remain in their
permitted operating ranges, and their installation requirements MUST always be fulfilled.
3. Under exposure to sunlight, the PV array may generate dangerous output in DC
voltage. Contacts with the DC wires, conductors and live components in the inverter
may result in lethal shocks.
4. High voltages in inver ter 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.
5. The DC input voltage of the PV array MUST never exceed the maximum input
voltage of the inverter.
6. DO NOT touch parts of the inverter during operation as heat will be induced and these
parts will exceed 60°C.

4 INSTALLING
41 Installation Requirement
1 Please install the inverters in places that can avoid inadvertent contact.
2 Installation method,location and surface must be fitting for the inverter's weight and dimensions
3. Please install the inverter in an accessible location for operation, future maintenance
and service.
4. 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.
5. DO NOT cover the inverter NOR place any objects on top of the inverter.
6. To ensure sufficient room for heat dissipation and maintenance, the dearing space between
inverter(s) and other surroundings is indicated below for reference:
7. Avoid direct exposure to sun light and rain and snow layup

Backwards

4.2 Mounting Location
1. DO NOT mount the inverter near any inflammable 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 inverter 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.

3 Mounting
1. Use the Heatsink bracket holes as a template and mark the drill holes. Drill 2 holes using
a 10mm bit to 70mm depth.
2. Fix the Inverter with the screws and expansion bolts packed in mounting accessories
4. Check both sides of the heat sink to ensure the inverter is stably attached.
4.4 Installing the PE cable
1.Insert the grounding conductor into the suitable terminal lug and crimp the contact.
2.Thread the MS13 screw through the terminal lug.
3.Tighten it firmly into the housing (screwdriver type: T25, torque: 2.5Nm).
