2 Safety

2.1 Appropriate Usage

The Sunny Boy is a PV inverter which converts the DC current of the PV array to AC current and feeds

it into the power distribution grid.

Principle of a PV plant with this Sunny Boy

The Sunny Boy may only be operated with PV arrays (modules and cabling) of protection class II. Do

not connect any sources of energy other than PV modules to the Sunny Boy.

When designing the PV plant, 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 device. 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 Description

"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 SMA Solar Technology AG shall void any warranty claims and the operation permission.

Capacitive discharge currents

PV modules with large capacities relative to ground, such as thin-film modules with cells on

a metallic substrate, may only be used if their coupling capacity does not exceed 1400 nF.

During feed-in operation, a discharge current flows from the cells to ground. The amount

of current depends on the manner in which the modules are installed (e.g., foil on metal

roof) and on the weather (rain, snow). This "normal" discharge current may not exceed

50 mA due to the fact that the inverter would otherwise automatically disconnect from the

grid as a protective measure.

2.2 Safety Instructions

DANGER!

Danger to life due to high voltages in the inverter.

• All work on the inverter may only be carried out by an electrically skilled person.

• The appliance is not to be used by children or persons with reduced physical, sensory

or mental capabilities, or lack of experience and knowledge, unless they have been

given supervision or instruction.

• Children should be supervised to ensure that they do not play with the appliance.

WARNING!

Risk of electric shock when pulling out the DC connectors under load.

If you disconnect the DC connectors from the inverter under load, an electric arc may

occur, leading to electric shock and burns.

• If the inverter is not equipped with an Electronic Solar Switch and the regulations in

the country of installation require an external DC switch-disconnector, install an

external DC switch-disconnector.

• Switch off the AC miniature circuit-breaker and disconnect the inverter on the DC side

before pulling out the DC connectors.

CAUTION!

Danger of burn injuries due to hot enclosure parts.

• Do not touch enclosure during operation.

• Only touch the lid during operation.

NOTICE!

Dust and water in the inverter can damage the device.

If the inverter is equipped with an Electronic Solar Switch, it will only provide IP21 degree

of protection once the Electronic Solar Switch has been pulled out. The inverter is therefore

no longer protected against water and dust. In order to also maintain the IP65 degree of

protection during temporary decommissioning, proceed as follows:

• Unlock and disconnect all DC connectors.

• Open all DC connectors and remove the cables.

• Close all DC inputs with the corresponding DC connectors and the supplied sealing

plugs.

• Securely attach the Electronic Solar Switch again.
