2 Safety
2.1 Intended Use
The SunnyTripower is a transformerless PV inverter with two MPP trackers which converts the direct
current of the PV array to grid-compliant three-phase current and feeds it into the utility grid.
The product is suitable for indoor and outdoor use.
The product must only be operated with PV arrays of protection classII, in accordance with
IEC61730, application classA. The PV modules must be suitable for use with this product.
PV modules with a high capacity to ground must only be used if their coupling capacity does not
exceed 3.5μF (for information on how to calculate the coupling capacity, see the Technical
Information "Leading Leakage Currents" at www.SMA-Solar.com).
All components must remain within their permitted operating ranges at all times.
The product must only be used in countries for which it is approved or released by SMA Solar
Technology AG and the grid operator.
Use this product only in accordance with the information provided in the enclosed documentation
and with the locally applicable standards and directives. Any other application may cause
personal injury or property damage.
Alterations to the product, e.g. changes or modifications, are only permitted with the express written
permission of SMA Solar Technology AG. Making unauthorized changes will void the warranty
and will normally result in invalidation of the operating permit. SMA Solar Technology AG shall not
be held liable for any damages caused by such changes.
Any use of the product other than described in the Intended Use section does not qualify as
intended use.
The enclosed documentation is an integral part of this product. Keep the documentation in a
convenient place for future reference and observe all instructions contained therein.
The type label must remain permanently attached to the product.
2.2 Skills of Qualified Persons
Only qualified persons are allowed to perform the activities marked in this document with a
warning symbol and the caption "Qualifiedperson". Qualified persons must have the following
skills:
• Knowledge of how an inverter works and is operated
• Training in how to deal with the dangers and risks associated with installing and using
electrical devices and systems
• Training in the installation and commissioning of electrical devices and systems
• Knowledge of the applicable standards and directives
• Knowledge of and compliance with this document and all safety precautions

2.3 Safety Precautions
This section contains safety precautions that must be observed at all times when working on or with
the product.
To prevent personal injury and property damage and to ensure long-term operation of the product,
read this section carefully and follow all safety precautions at all times.
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 uninsulated cable ends.
• Do not touch the DC conductors.
• Do not touch any live components of the inverter.
• Have the inverter mounted, installed and commissioned by qualified persons with the
appropriate skills only.
• 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, page34).
Danger to life due to electric shock
Touching an ungrounded PV module or an array frame can cause a fatal electric shock.
• Connect and ground the PV modules, array frame and electrically conductive surfaces so
that there is continuous conduction. Observe the applicable local regulations.
Risk of burns due to hot enclosure parts
Some parts of the enclosure can get hot during operation.
• Do not touch any parts other than the lower enclosure lid of the inverter during operation.
Damage to the seal of the enclosure lids in subfreezing
If you open the upper and lower enclosure lids in subfreezing conditions, the enclosure's seal can
be damaged. This can lead to moisture entering the inverter.
• Do not open the inverter at ambient temperatures lower than -5°C.
• If a layer of ice has formed on the seal of the lid in sub-zero conditions, remove it prior to
opening the enclosure lids of the inverter (e.g. by melting the ice with warm air). Observe the
applicable safety regulations.
