2.1 Appropriate Usage

The Sunny Boy 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 this Sunny Boy
The Sunny Boy 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 Boy.
PV modules with large capacities relative to ground, such as thin-film modules with cells on a metallic substrate, are only to be implemented if their coupling capacity is below 50 nF/kWp.
During grid feeding, a leakage current whose magnitude depends on the manner in which the modules are installed and on the weather (rain, snow) flows from the cells to ground. This operational leakage current is not to exceed a value of 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/en/SunnyDesign) will assist you. The manufacturer of the PV modules must have approved the modules for use with this Sunny Boy 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/en).
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 operation permission.

Safety SMA Solar Technology AG

2.2 Safety Instructions

DANGER!
Danger to life due to high voltages.
• All work on the Sunny Boy must only be carried out by a qualified personnel.
CAUTION!
Danger of burn injuries due to hot housing parts!
• Do not touch the housing of the Sunny Boy during operation.
NOTICE!
Foreign objects or water entering the Sunny Boy can damage the device!
Once the Electronic Solar Switch has been pulled out, the Sunny Boy only provides protection degree IP21. The Sunny Boy is then no longer protected against water and contamination with dirt!
In order that the protection level IP65 is also provided during a temporary decommissioning, proceed as follows:
• Unplug all DC plug connectors and seal them with the protecting caps provided.
• Attach the Electronic Solar Switch again.
Grounding the PV generator
Comply with the local requirem ents for groundi ng the module s an d the PV generator. SMA reccomends to electrically bond the module frames, the racks and all metal surfaces and ground these in order to have optimal protection of the system and personnel.

4 Mounting

4.1 Selecting 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 Boy on flammable construction materials.
• Do not mount the Sunny Boy near highly flammable materials.
• Do not install the Sunny Boy in potentially explosive areas!
CAUTION!
Danger of burn injuries due to hot housing parts!
The temperature of individual parts of the housing, in particular the temperature of the heatsink and the components inside the Sunny Boy can reach more than 60 °C. Touching could result in burns!
Weight
CAUTION!
Risk of injury due to the heavy weight of the Sunny Boy!
The Sunny Boy weighs more than 28 kg.
• Consider the weight of the Sunny Boy when choosing the location and method of installation.
Ambient Conditions
• The mounting location and mounting method must be suitable for the weight and dimensions.
• Mount on a solid surface.
• The installation location must be accessible at all times (do not mount in inaccessible places).
• The Sunny Boy must be easy to remove from the mounting location at any time.
• The Sunny Boy must not be in operation in ambient temperatures outside the range of -25 °C and +60 °C. For optimal operation, the ambient temperature should not exceed +40 °C.
• Do not expose the Sunny Boy to direct sunlight, so as to avoid power reduction due to excessive heating.

SMA Solar Technology AG Mounting
• In a living area, do not mount the unit on plasterboard walls (or similar) in order to avoid audible vibrations.
The Sunny Boy can make noises when in use which can be regarded as a nuisance when installed in a living area.
• Vertical installation or tilted backwards by max. 45°.
• Install at eye level to allow operating modes to be read at all times.
• Never install the device with a forward tilt.
• Do not install horizontally.
Safety Clearances
Observe the following safety clearances to walls, other devices or other objects in order to guarantee sufficient heat dissipation and enough space for removing the Electronic Solar Switch:
Direction Minimum Clearance
Sides 20 cm
Top 20 cm
Bottom 50 cm
Front 5 cm

Mounting SMA Solar Technology AG

4.2 Mounting the Sunny Boy

To make the job easier, we recommend you use the supplied wall bracket to mount the Sunny Boy. For vertical installation on solid concrete or block walls, for example, you can fit the bracket using 8 mm x 50 mm hexagon bolts to DIN 571 standard, stainless steel type, and with wall plugs type SX10.
When selecting the mounting materials, be sure to take into account the weight of the Sunny Boy (28 kg).
If you do not want to use the supplied wall bracket as a template, observe the dimensions shown in the illustration below. The procedure for mounting the inverter using the wall bracket is described on the following pages.

1. Mount the wall bracket (1). In order to mark the positions for the drill holes, you can use the wall bracket as a drilling template.
2. Now han g the Su nny Boy onto the wall brac ket (2) using its upper mounting plate so that it cannot be moved sideways.
3. Fix the Sunny Boy onto its bracket by screwing the supplied M6x10 bolt into the central threaded hole at the bottom of the bracket (3).
4. Make sure that the Sunny Boy is positioned securely on the bracket.
