Page 2: Notes On This Manual
1 Notes on this Manual General Notes The KSY series is a transformerless solar inverter with indenpendent MPP tracker. It converts the direct current (DC) from a photovoltaic (PV) array to grid-compliant alterna�ng current (AC) and feeds it into the u�lity grid. 1.1 Area of validity This manual describes moun�ng, installa�on, commissioning and maintenance of the following inverters:... - Page 3 1.3 Symbols used in this manual The safety precau�ons and general informa�on are used in this manual as follows: DANGER indicates a hazardous situa�on which, if not avoided, will result in death or serious injury. WARNING indicates a hazardous situa�on which, if not avoided, can result in death or serious injury.
- Page 4 Danger to life due to high voltages of the PV array When exposed to sunlight, the PV array generates dangerous DC voltage which is present in the DC conductors and the live components of the inverter. Touching the DC conductors or the live components can lead to lethal electric shocks.
- Page 5 Possible damage to health as a result of the e ects of electromagnetic radiation • Please maintain a distance of at least 20cm from the inverter when it is in opera�on. Grounding the PV array • Comply with local regula�ons for grounding the PV array. We suggest the frames of PV modules must be reliably grounded.
- Page 6 Damage to the inverter due to electrostatic discharge •Touching electronic components can cause damage to or destroy the inverter through electrosta�c discharge. • Ground yourself before touching any component.

- Page 9 4 Mounting 4.1 Ambient condi�ons Be sure the inverter is installed out of the reach of children. Mount the inverter in areas where it cannot be touched inadvertently. Ensure good access to the inverter for installa�on and possible service. To make sure that heat can dissipate, observe the following minimum clearance to walls, other inverters, or objects: Direc�on Min.
- Page 10 If mounted in a residen�al area, we recommend moun�ng the inverter on a solid surface. Plasterboard and similar materials are not recommended due to audible vibra�ons when in use. 10. Do not put any objects on the inverter. 11. Do not cover the inverter.
- Page 11 4.2 Selec�ng the moun�ng loca�on Danger to life due to re or explosion • Do not mount the inverter on flammable construc�on 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. Mount the inverter ver�cally or �lted backward by a maximum of 15°.
- Page 12 4.3 Moun�ng the inverter with the wall bracket Mounting procedures: 1. Use the wall bracket as a drilling template and mark the posi�ons of the drill holes. Drill 2 holes required using a drill with 10 mm bit. The holes must be about 70 mm deep. Keep the drill ver�cal to the wall, and hold the drill steady to avoid �lted holes.
- Page 13 4. Push the inverter as far as possible and a�ach it to both sides of the wall bracket using the M5 screws. Install an an�the� lock (op�onal), the lock is prepared by customer. Dismante the inverter in reverse order.

Page 14: Electrical Connection
5 Electrical Connection 5.1 System layout of units without integrated DC switch Local standards or codes may require that PV systems are fi�ed 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%. - Page 15 5.3 AC connec�on 5.3.1 Conditions for the AC connection Cable Requirements The grid connec�on is established using three conductors (L, N, and PE). We recommend the following specifica�ons for stranded copper wire. KSY- 1KW-4.2KW- 1Ph - 1MPPT Object Descrip�on Value External diameter 9 to 14 mm Conductor cross-sec�on...
- Page 16 5.4 DC Connec�on Danger to life due to high voltages in the inverter • Before connec�ng the PV array, ensure that the DC switch is switched off and that it cannot be reac�vated. • Do not disconnect the DC connectors under load. 5.4.1 Requirements for the DC Connec�on Use of Y adapters for parallel connection of strings The Y adapters must not be used to interrupt the DC circuit.
- Page 17 5.4.2 Assembling the DC connectors Assemble the DC connectors as described below. Be sure to observe the correct polarity. Cable requirements: External diameter: 5 mm to 8 mm Conductor cross-sec�on: 2.5 mm² to 6 mm² Number of conductors: at least 7 Nominal voltage: at least 600V Proceed as follows to assemble each DC connector.
- Page 18 Insert contact cable assembly into back of the MC4 plug connector un�l it audibly locks into place. 5. Screw the cap nut by using the torque of 2.6~2.9Nm. A�er screw the cap nut �ghtly, connect the fault-free strings of the PV generator into DC input connectors on the inverter un�l it audibly locks into place.
- Page 19 5.4.3 Connec�ng the PV array The inverter can be destroyed by overvoltage If the voltage of the strings exceeds the maximum DC input voltage of the inverter, it can be destroyed due to overvoltage. All warranty claims become void. • Do not connect strings with an open-circuit voltage greater than the maximum DC input voltage of the inverter.
- Page 20 7 Commissioning Risk of injury due to incorrect installation • We strongly recommend carrying out preliminary checks before commissioning to avoid possible damage to the device caused by faulty installa�on. 7.1 Electrical checks Carry out the main electrical tests as follows: Check the PE connec�on with a mul�meter: make sure that the inverter’s exposed metal surface has a ground connec�on.

Page 21: Quick Troubleshooting
7.3 Start-Up A�er finishing the electrical and mechanical checks, switch on the miniature circuit-breaker and DC-switch in turn. Once the DC input voltage is sufficiently high and the grid-connec�on condi�ons are met, the inverter will start opera�on automa�cally. Usually, there are three states during opera�on: Indicator lights in Green/Red/Yellow correspondently refer to: During periods of low radia�on, the inverter may con�nuously start up and shut down. -
Page 22: Disconnecting The Inverter From Voltage Sources
8 Disconnecting the Inverter from Voltage Sources Prior to performing any work on the inverter, disconnect it from all voltage sources as described in this sec�on. Always adhere strictly to the prescribed sequence. Procedure: Disconnect the miniature circuit-breaker and secure against reconnec�on. Disconnect the DC switch and secure against reconnec�on. -
