Aufgabe_ SMC-TL
The Sunny Mini Central is a transformerless PV inverter, which converts the direct current of the
PV array to grid-compliant alternating current and feeds it into the electricity grid.
The Sunny Mini Central is suitable for indoor and outdoor use.
The Sunny Mini Central should only be operated with PV arrays (PV modules and cabling) of
protection class II. The PV modules used must be released by the module manufacturer for use with
this Sunny Mini Central.
PV modules with a high capacity to earth should only be used if their coupling capacity does not
exceed 1,400 nF.
All components must remain within their permitted operating ranges at all times.
National ap proval and rel ease
The product may only be used in countries for which it is approved or released by
SMA Solar Technology AG and the network operator.
STSatz_Best Verwend_Produkt ändern
For safety reasons, it is forbidden to modify the product or install components that are not explicitly
recommended or distributed by SMA Solar Technology AG.

STSatz_Best Verwend_Doku beachten und zugänglich
The enclosed documentation is an integral part of this product.
• Read and observe the documentation.
• Keep the documentation in a convenient place for future reference.
The work described in this document must be performed by skilled persons only. Skilled persons must
have the following qualifications:
• Knowledge of how an inverter works and is operated
• Training in how to deal with the dangers and risks associated with installing and operating
electrical devices and plants

2.2 Qualifications of Skilled Persons

12 SMC9-11TLRP-IA-en-51 Installation Manual
2 Safety SMA Solar Technology AG
Electric Shock
SiHiw_Stromschlag durch hohe Spannungen
High voltages are present in the live components of the inverter. Touching these components can
cause fatal electric shock.
• Always disconnect the inverter from voltage sources before performing any work on it as
described in this document (see section 9).
SiHiw_nicht geerdetes PV-Modul
Touching an unearthed PV module or an array frame can cause a fatal electric shock.
• Connect and earth the PV modules, array frame and electrically conductive surfaces so that there
is continuous conduction. Observe the applicable local regulations.
Burn Hazards
SiHiw_Verbrennungen durch Gehäuseteile
Some parts of the enclosure can become hot during operation.
• During operation, touch the inverter on the enclosure lid only.
Environmental Influences
SiHiw_ESS _Dichtig keit
When closed and with the ESS plugged in, the inverter has the degree of protection IP65.
If the ESS is not plugged in or incorrectly plugged in during operation, moisture and dust can
penetrate the inverter. If the ESS is not correctly plugged in, this can cause contacts in the ESS to wear
or the ESS might fall out of the socket. This can result in yield loss and damage to the ESS.
• If the ESS is not plugged in, the inverter must be protected against moisture and dust.
• After performing any work on inverters, plug the ESS back in as follows:
– Do not tighten the screw inside the ESS.
– Firmly plug in the ESS until it is flush with the enclosure.
– Ensure that the gap between the ESS and the enclosure is no more than 1 mm.
Electrostatic Discharge
SiHiw_Vor Berühren erden
Touching electronic components can cause damage to or destroy the inverter through electrostatic
discharge.
• Earth yourself before touching any components.

Tapping You can operate the display by tapping it:
• Single tap: Switch on display
illumination or switch to the next
display message.
• Tapping twice: The inverter shows the
display messages from the start-up
phase.
After two minutes, the backlight switches off
automatically.
Inverter This symbol defines the function of the green
LED. The green LED indicates the operating
state of the inverter.
Earth fault This symbol defines the function of the red
LED. The red LED indicates an earth fault, a
defective varistor or a defective string fuse.
Observe the documentation. This symbol defines the function of the
yellow LED which indicates a fault or
disturbance. Read the manual to remedy the
fault or disturbance.
Protective conductor This symbol indicates the position for the
protective conductor connection.
Danger to life due to high
voltages in the inverter;
observe waiting time.
High voltages that can cause fatal electric
shocks are present in the live components of
the inverter. The capacitors take ten minutes
to discharge. Prior to performing any work
on the inverter, disconnect it from all voltage
sources, as described in this document
(see section 9).

Aufgabe_ESS
The ESS and the DC connectors form a DC load disconnect unit.
There are two types of ESS with different plug designs. The function of the ESS is identical in both
cases.
Funktion_ESS
When plugged in, the ESS forms a conductive path between the PV array and the inverter. Removing
the ESS interrupts the DC electric circuit and removing all DC connectors disconnects the PV array
completely from the inverter.

Item Designation Explanation
A Plug Depending on the type of ESS, the metal
mounting tabs in the plug are visible or in a
plastic enclosure.
BLabel • If the ESS is plugged in, the DC
electric circuit is closed.
• To interrupt the DC electric circuit,
you must first perform steps 1 and 2
consecutively.
• Remove the ESS.
• Remove all DC connectors.
