2.1 Appropriate Usage

The Sunny Mini Central is a PV inverter that converts the DC current of solar cells to AC current and feeds it into the public grid.
Principle of a PV System with the Sunny Mini Central
L1
L2
L3
The Sunny Mini Central may only be operated with PV generators (modules and cabling) of protection class II. Do not connect any sources of energy other than PV modules to the Sunny Mini Central.
PV modules with large capacities relative to ground, such as thin-film modules with cells on a metallic substrate, are therefore only to be implemented if their coupling capacitance is below 50 nF/kWp. During grid feeding, a leakage current flows from the cells to the earth. The magnitude of this current depends on the manner in which the modules are installed and, to no small extent, on the weather (rain, snow). This operational leakage current is not to exceed 50 mA.
When designing the PV system, ensure that the values comply with the permitted operating range of all components at all times. The free design program "Sunny Design" (www.SMA.de/SunnyDesign) will assist you. The manufacturer of the PV modules must have approved the modules for use with this Sunny Mini Central unit. You must also ensure that all measures recommended by the module manufacturer for long-term maintenance of the module properties are taken (see also Technical Information "Module Technology", in the download area of www.SMA.de).

Security SMA Solar Technology AG
Do not use the Sunny Boy for purposes other than those described here. Alternative uses, modifications to the Sunny Boy or the installation of components not expressly recommended or sold by the manufacturer void the warranty claims and operating license.

2.2 Safety Precautions

DANGER!
Danger to life due to high voltages in the Sunny Mini Central!
All work on the Sunny Mini Central must be carried out by a qualified electrician.
DANGER!
Danger of burn injuries due to hot housing parts!
• Do not touch the housing body during operation.
• Only touch the cover during operation.
NOTICE!
Dust or water entering the Sunny Mini Central can damage the device!
If the Electronic Solar Switch has been pulled out, the Sunny Mini Central only has a protection rating of IP21.
If the device has been temporarily decommiss ioned, proceed a s follows to restore the IP65 protection rating:
• Unplug all DC plug connectors and seal them with the protecting caps provided.
• Attach the Electronic Solar Switch.
Grounding the PV generator
Comply with the local requirements for grounding the modules and the PV generator. SMA Solar Technology recommends connecting the generator frame and other electricity conducting surfaces such that there is continuous conduction and to connect them to the ground in order to reach maximum protection for property and persons.

4.1 Selection of the Mounting Location

DANGER!
Danger to life due to fire or explosion!
Despite careful construction, a fire can occur with electrical devices.
• Do not mount the Sunny Mini Central on flammable construction materials.
• Do not mount the Sunny Mini Central in areas where highly flammable materials are stored.
• Do not mount the Sunny Mini Central in areas where there is a risk of explosion.
CAUTION!
Danger of burn injuries due to hot housing parts!
• Mount the Sunny Mini Central such that it cannot be touched inadvertently.

4.1.2 Ambient Conditions

• The mounting location and mounting method must be suitable for the weight and dimensions of the Sunny Mini Central.
• Mounting on a solid surface.
• The mounting location must be accessible at all times.
• The ambient temperature should be below 40 °C at all times to guarantee optimal operation.
• Do not expose the Sunny Mini Central to direct sunlight to avoid a power reduction due to excessive heating.
• In a living area, do not mount the unit on plasterboard etc. walls as otherwise audible vibrations are likely to result.
The Sunny Mini Central can make noises when in us e which can be se en a s a nuis anc e when i nst alled in a living area.

4.1.3 Safety Clearances

Observe the following minimum clearances to walls, other devices or objects to guarantee sufficient heat dissipation and enough space for pulling the Electronic Solar Switch handle.
Direction Minimum Clearance
Sidewise 30 cm Above 30 cm Bottom 50 cm Front 5 cm
Electronic
Solar
Switch
Multiple Sunny Mini Centrals installed in areas with high ambient temperatures
The individual Sunny Mini Central units must be far enough apart to ensure that the individual Sunny Mini Central units do not take in the cooling air of the neighboring unit.
If necessary, increase the clearance and ensure that the supply of cool air is sufficient to cool the Sunny Mini Centrals.
