2 Foreword

For detailed information on troubleshooting and on how to use the Sunny Boy and the

various communications options, please see the operating instructions.

"Sunny Design" helps you design the system and check string size taking the relevant

inverter into consideration. Further information on Sunny Design is available at

www.SMA.de.

2. 1 Target Group

This installation manual is intended solely for qualified personnel. Its aim is to help install

and set up SMA inverters type “SB 4200TL HC Multi-String“ or “Sunny Boy SB 5000TL

HC Multi-String“ quickly and correctly.

The Sunny Boy inverters are equipped with the "SMA grid guard". This is a type

of automatic disconnection device. It ensures that the Sunny Boy complies with the

VDEW (Verband der Elektrizitätswirtschaft – German Electricity Industry Associa-

tion) regulations for the connection and parallel operation of electrical power units

to the low-voltage grid of the electricity supply company and with DIN VDE 0126-

1-1, which forms a part of these regulations.

Notice!

The Sunny Boy may only be installed by qualified personnel. The installer

must be approved by the local energy supplier. Read this "installation

guide" carefully. All prescribed safety regulations, the technical connec-

tion requirements of the local energy supplier and all applicable provi-

sions must be adhered to.

2. 2 Appropriate Usage

The Sunny Boy is designed for operation in grid-connected PV systems. Any other use

of the leads to loss of the right to all warranty claims and may lead to a fault in the

device. This includes, among other things, the operation at voltage sources without any

current limit. When in doubt, contact SMA.

Plant Design

The Sunny Boy may only be operated with PV-generators (Modules and according ca-

bles) with protection class II.

It is mandatory to ensure that all components will operate within the specified operating

range. The free design tool "Sunny Design" (www.SMA.de/SunnyDesign) will help you

with this.

The manufacturer of the modules should have approved the modules for operation with

this Sunny Boy. It is furthermore advisable to implement all measures for maintaining the

module performance (see also Application Note 2 "Module Technology" in the down-

load area of www.SMA.de).

2. 3 Validity of the Documentation

The Sunny Boy SB 4200TL HC Multi-String and Sunny Boy SB 5000TL HC Multi-String

are identical except for the technical data. The devices are referred to as Sunny Boy in

case the information applies for both models. The full device name is used in case of

device specific information.

3 Safety Instructions

Caution! Overvoltage!

Check the system design using the "Sunny Design" design tool

(www.SMA.de) or by calling the SMA Service Line. Overvoltage damages

the Sunny Boy and results in the exclusion of all warranty claims!

Warning! High voltages!

Work on the Sunny Boy with the cover removed must be carried out by a

qualified electrician. High voltages are present in the device. Before work-

ing on the Sunny Boy with the cover removed, the AC and DC voltages

must be disconnected from the Sunny Boy and the capacitors must be dis-

charged.

The Sunny Boy must be disconnected from the mains grid and precautions

must be taken to prevent the grid being inadvertently reconnected. In ad-

dition, the connections to the PV generator must be disconnected.

After isolating the AC and DC voltage, you must wait approx. 30 minutes

for the capacitors in the Sunny Boy to discharge. Only then is it safe to

open the unit by removing the cover. You must also make sure that no

voltage is present in the device.

Caution! Electrostatic charge!

When working on the Sunny Boy and handling the components, remem-

ber to observe all ESD safety regulations. Electronic components are vul-

nerable in terms of electrostatic charge. Discharge any electrostatic

charge by touching the grounded enclosure before handling any electron-

ic component.

Notice! Entry of water and dirt!

Once the handle of the Electronic Solar Switch has been pulled out, the

Sunny Boy provides protection degree IP21. The Sunny Boy is then no

longer protected against water and contamination with dirt!

Grounding the PV generator

Pay attention to local regulations for the grounding of the modules and 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.
