1 Notes on this Manual
1.1 General Notes
Solplanet inverter is a transformerless solar inverter with two
independent MPP trackers. It converts the direct current (DC)
from the photovoltaic (PV) arrays to grid-compliant alternating
current (AC) and feeds it into the grid.
1.2 Area of Validity
This manual describes the mounting, installation, commissioning
and maintenance of the following Solplanet inverters:
ASW15K-LT
ASW20K-LT
Observe all documentation that accompanies the inverter. Keep
them in a convenient place and available at all times.
1.3 Target group
This manual is for qualified electricians only, who must perform
the tasks exactly as described.
All persons installing inverters must be trained and experienced
in general safety which must be observed when working on
electrical equipment. Installation personnel should also be
familiar with local requirements, rules and regulations.
Qualified persons must have the following skills:
• Knowledge of how an inverter works and is operated
User manual UM0003_ASW15-20k-LT_EN_V01_0121
5
• Training in how to deal with the dangers and risks associated
with installing, repairing and using electrical devices and
installations
• Training in the installation and commissioning of electrical
devices
• Knowledge of all applicable laws, standards and directives
• Knowledge of and compliance with this document and all safety
information.
1.4 Symbols used in this manual
Safety instructions will be highlighted with the following symbols:
DANGER indicates a hazardous situation which, if not be
avoided, will result in death or serious injury.
WARNING indicates a hazardous situation which, if not be
avoided, can result in death or serious injury.
CAUTION indicates a hazardous situation which, if not be
avoided, can result in minor or moderate injury.

2 Safety
2.1 Intended use
1. The inverter converts the direct current from the PV arrays into
grid-compliant alternating current.
2. The inverter is suitable for indoor and outdoor use.
3. The inverter must only be operated with PV arrays (PV
modules and cabling) of protection class II in accordance with
IEC 61730, application class A. Do not connect any sources of
energy other than PV modules to the inverter.
4. PV modules with a high capacity to ground must only be used
if their coupling capacity does not exceed 7.15μF.
5. When the PV modules are exposed to light, a DC voltage is
supplied to the inverter.
6. When designing the PV power plants, ensure that the values
comply with the permitted operating range of all components at
all times.
NOTICE indicates a situation which, if not be avoided, can
result in property damage.
INFORMATION that is important for a specific topic or goal,
but is not safety-relevant.

7. The inverter must only be used in countries for which it is
approved or released by AISWEI and the grid operator.
8. Use this product only in accordance with the information
provided in this documentation and with the locally applicable
standards and directives. Any other application may cause
personal injury or property damage.
9. The type label must remain permanently attached to the
product.

2.2 Important safety information
Danger to life due to electric shock when live components or
cables are touched
• All work on the inverter must only be carried out by qualified
personnel who have read and fully understood all safety
information contained in this manual.
• Do not open the product.
• Children must be supervised to ensure that they do not play
with this device.
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. If you
disconnect the DC connectors from the inverter under load,
an electric arc may occur leading to electric shock and burns.
• Do not touch non-insulated cable ends.
• Do not touch the DC conductors.
• Do not touch any live components of the inverter.
• Have the inverter mounted, installed and commissioned only
by qualified persons with the appropriate skills.
•If an error occurs, have it rectified by qualified persons only.
•Prior to performing any work on the inverter, disconnect it
from all voltage sources as described in this document(see
Section 9 "Disconnecting the Inverter from Voltage Sources").
User manual UM0003_ASW15-20k-LT_EN_V01_0121

Risk of injury due to electric shock
Touching an ungrounded PV module or array frame can
cause a lethal electric shock.
• connect and ground the PV modules, array frame and
electrically conductive surfaces so that there is continuous
conduction.
Risk of burns due to hot enclosure parts
Some parts of the enclosure can get hot during operation.
• During operation, do not touch any parts other than the
enclosure lid of the inverter.
Damage to the inverter due to electrostatic discharge
Internal components of the inverter can be irreparably
damaged by electrostatic discharge.
• Ground yourself before touching any component.
