2 Safety
2.1 Appropriate Usage
The NET Piggy-Back is an additional module for the Sunny Boy Control that allows you to e-mail the
operating data of your PV system directly to the Sunny Boy Control. The NET Piggy-Back comes in
four different versions. Depending on which version you order, the NET Piggy-Back can send data
using one of the following methods:
• analog telephone network
•ISDN
• GSM (cellular phone network)
•Ethernet
The Sunny Boy Control automatically sends the yield data of your system as well as any failure
messages to up to three recipients everyday. You can also forward this data to your own cellular
phone with an e-mail-to-SMS service. The Sunny Boy Control with NET Piggy-Back can dial up to
the Internet using any Internet service provider (ISP). For sending e-mails, SMA provides a mail
server free of charge or you can use the SMTP or ASMTP server of your provider.
Besides sending e-mails, the NET Piggy-Back also allows you to dial-in to your PV system with a PC
and a compatible modem. You can therefore use public telephone network to perform remote
diagnostics and configurations.
The figure below shows the principle and the possibilities of communication via the NET Piggy-Back.
The NET Piggy-Back can be retrofitted into all Sunny Boy Control (SBCO02) devices and Sunny
Boy Control Plus (SBCOP02) devices with NET sockets.
Establishing a Connection with the ISDN NET Piggy-Back
The ISDN NET Piggy-Back cannot be connected to a Sunny Boy Control via an analog
modem. To establish such a connection, you must use an ISDN modem (terminal adapter)
or an ISDN PC card!

E-mail Formats
Reports can be generated on the following events:
• System info: report on the energy yields of your system
• Errors/warnings: report on any errors or warnings which may have occurred
Errors and warnings are always transmitted together in a report. If you configure warnings as 'daily
reports' and errors as 'hourly reports', notification will be sent at the next hour after an error occurs.
This report contains all the errors and warnings that have occurred until the time it is sent. If a
warning is issued, it will be reported at the end of the day.
2.2 Safety Precautions
DANGER!
Danger to life when opening the Sunny Boy Control.
All work on the Sunny Boy Control / Sunny Boy Control Plus and Sunny Central Control
may only be carried out by a qualified electrician.
User Manual Supplement
This document is a supplement to the "Sunny Boy Control/Control Plus" user manual.

3 The NET Piggy-Back
When the NET Piggy-Back is installed, you have the option of having the operating data of your PV
system sent to you by e-mail or forwarded to you by SMS. The NET Piggy-Back offers you
convenient access to the current status and energy yields of your PV system regardless of your actual
location.
This document describes the additional functions that are enabled when the NET Piggy-Back is
installed. It supplements the Sunny Boy Control / Control Plus documentation and contains critical
information for the installer and operator regarding the function, installation and use of the NET
Piggy-Back.

5 Initial Start-up
Once all connections have been properly made, you can switch on the Sunny Boy Control. The NET
Piggy-Back can be configured after the boot process is complete (this can take a few minutes).
Configuring the Sunny Boy Control to send e-mails can be done either on the device itself (see
Section 9) or from a local PC running the Sunny Data Control system monitoring software (see
Section 8).
5.1 NET Piggy-Back "Analog Modem" Version
The following basic parameter settings must be made on the Sunny Boy Control / Sunny Boy
Control Plus to enable an incoming and outgoing data link.
Required parameter settings on the device:
• CO_NET Auto Answer:
- Set a value greater than "0" here (recommendation: "2").
• FI_ISP Phone No:
- The access number of your Internet service provider (ISP).
• FI_ISP User ID:
- The user ID that you received from the Internet service provider (ISP).
• FI_ISP Password:
- The password that corresponds to the user ID.
For information on configuring the device for e-mail transmission, see Section 6.
Password Protection
To make changes in the Sunny Data Control menu or on the Sunny Boy Control itself, the
installer password must be entered first. The passwords are written down a separate
information leaflet included in the Sunny Boy Control delivery package. The default
installer password is only valid until the installer sets his or her own password.
Checklist for Parameter Setting
When configuring the Sunny Boy Control, we recommend that you fill out the enclosed
checklist and perform all the settings on a step by step basis. With the help of this checklist
you should be able to avoid making any incorrect or incomplete settings in the Sunny Boy
Control / Control Plus.

SMA Solar Technology AG Initial Start-up
Technical Description NETPB-TEN081708 19
5.2 NET Piggy-Back "ISDN" Version
The following basic parameter settings must be made on the Sunny Boy Control / Sunny Boy
Control Plus to enable an incoming and outgoing data link.
Required parameter settings on the device:
•CO_NET-ISDNMSN:
- Telephone number used to receive calls.
• CO_NET Auto Answer:
- Set a value greater than "0" here (recommendation: "2").
• FI_ISP Phone No:
- The access number of your Internet service provider (ISP).
• FI_ISP User ID:
- The user ID that you received from the Internet service provider (ISP).
• FI_ISP Password:
- The password that corresponds to the user ID.
For information on configuring the device for e-mail transmission, see Section 6.
5.3 NET Piggy-Back "GSM" Version
In contrast to landline phones, cellular network providers make a clear distinction between
voice services and data services. For example, they provide
different numbers for voice and data with GSM devices.
A separate data number is required for incoming data connections (access by modem) on the data
logger. This can be requested when arranging the contract with the network provider. Retroactive
activation is also possible via telephone by calling the relevant technical service line and stating the
customer password defined in the contract. If in doubt, please consult your cellular network
provider.
Outgoing data connections from the data logger (access to an Internet service provider) are
possible without an additional data number.
If not just outgoing, but also incoming data connections are to be enabled,
a dedicated data number which operates over the CSD data service is an absolute necessity. Other
data services are not supported. A standard SIM card with additional data connectivity always has
two telephone numbers (multi-numbering).
The GSM data service must be activated.
Please note that the GSM data service must be activated
in your contract. If in doubt, please consult your cellular network provider.

Initial Start-up SMA Solar Technology AG
20 NETPB-TEN081708 Technical Description
5.3.1 Outgoing Data Connection
This data connection method allows you to send your system data by e-mail using your Internet
service provider. You do not require an additional data number.
Required parameter settings on the device:
•CO_NET-GSMPIN:
- The respective PIN number of the SIM card.
• FI_ISP Phone No:
- The access number of your Internet service provider (ISP).
• FI_ISP User ID:
- The user ID that you received from the Internet service provider (ISP).
• FI_ISP Password:
- The password that corresponds to the user ID.
For information on configuring the device for e-mail transmission, see Section 6.
5.3.2 Incoming Data Connection
This data connection method allows you to access the system and set system parameters or retrieve
available data from a PC. The SIM card requires a data connection through the CSD data service
in order for the NET Piggy-Back to receive data. Other data services such as GPRS are not
available.
Prepaid Card
If you would like to use a prepaid card, please consult your cell phone provider in
advance concerning the card's loading options.
Access Number of your Service Provider
The access number of your Internet service provider depends on the cell network
of your SIM card. You receive this telephone number from your Internet service provider.
Prepaid Cards
In most cases, prepaid cards cannot be used for this purpose.
If in doubt, please consult your cell phone network provider.
