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

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).

5. COMMISSIONING
5.1 Safety Instructions
1. Measure the frequency and voltage of grid connection and make sure they follow the
inverter’s grid connection specications.
2. An external circuit- breaker on the AC side (or a fuse)at1.25*AC rated current is
strongly recommended.
3. Reliability of all earth connections must be tested and valid .
4. Before commissioning, disconnect the inverter and the circuit - breaker or fuse, and
prevent accidental reconnection.
5.2 AC Wire Assembly and Connection
5.2.1 AC Commissioning
5.3 DC Wire Assembly and Connection
1. PV modules of the connected strings must be of: the same time, identical alignment
and tilting angle.
2. Before commissioning and connecting the PV arrays, the DC switch MUST be open.
3. Parallel strings must have the samenumber of modules.
4. It is mandatory to use the DC connectors within package for the connection of PV
5. The polarity of the PV arrays MUST be compatible to the DC connectors of the inverter.
6. The DC input voltage AND DC input current of the PV array MUST never exceed the maximum
input allowance of the inverter

7. START UP AND OPERATION
7.1 Safety Check Before Start Up
Please check before switching on any v oltage resources connected to the inverter and
closing inverter’s DC switch:
1. Grid Voltage: Check the grid voltage at point of connection at the inverter complies
with permitted range of the inverter.
2. Mounting of the inverter: Check if the inverter is properly mounted.
3. DC Connectors: Check if the DC connectors are installed correctly on terminals.
4. AC Connectors and Wire Assembly: Check if wires are assembled correctly on the AC
side and if the AC connector is properly and securely installed. Check if the AC
connector is rmly plugged into AC terminal.
5. Cables: Check if all cables are reliably connected. Check if the connections are
eective, while the insulations are undamaged.
6. Groundings: Check all groundings using multimeter and if all exposed metal parts of
the inverter are properly grounded.
7. DC Voltage: Check if the largest open - circuit voltage of PV arrays complies with the
permitted range.
8. DC Polarity: Check if the wires from DC voltage resource are connected to terminals
with correct polarity.
9. Grounding Resistance: Check if the grounding resistance of PV strings >1MOhm using
a multimeter.
The inverter will start to operate when DC input voltage and grid conditions meet the
requirements of inverter startup.

8. DISCONNECTING FROM VOLTAGE SOURCES
Before proceeding any operations on inverter, please disconnect the inverter from all
voltage resources as described in this manual.
Following these steps in described sequence are mandatory.
1. Disconnect miniature circuit - breaker and prevent from unintentional reconnections.
2. Open the DC switch and prevent the switch from closing unintentionally.
3. Use clamps to ensure there is no electrical current in DC wires.
4. Disconnect all DC connections and resources. Unplug the DC connectors, and DO
NOT pull the cables.
5. Use multimeter to ensure the voltage on DC terminals of inverter is 0.
6. Unscrew and remove the AC connector.
Danger to life due to high voltages.
Inverter capacitors need 5 minutes to be completely de - energized.
When an error occurs, DO NOT remove the cover of the inverter onsite. Improper
operations and attempts may induce electric shock.
