The Meter Connection Box SMA Solar Technology AG
2 The Meter Connection Box
The Meter Connection Box records meter pulses from an energy meter and supplies the data to the
Sunny WebBox from SMA Solar Technology AG. The data can be used to display the energy
consumption, grid feed-in and self-consumption. Depending on the requirements, the Meter
Connection Box can be connected, as displayed, to one of three energy meter types:
• Option 1: Connection to the PV yield meter
• Option 2: Connection to the feed-in meter
• Option 3: Connection to the grid consumption meter
The data is displayed by SMA communication products. The communication is carried out via RS485.
The voltage is supplied by a plug-in power supply.

3.1 Appropriate Usage
The Meter Connection Box allows the meter pulses of an energy meter to be transmitted exclusively
to the Sunny WebBox.
Only connect the Meter Connection Box to energy meters that meet the requirements specified in the
technical data (see "Requirements for Energy Meters" (page26)).
Information on Sealed Energy Meters
If the energy meter that you would like to connect to the Meter Connection Box is sealed,
contact your electric utility company. Never remove the seal on the energy meter without
consulting your electric utility company!
Information on Connecting the Unit to Bi-directional Meters
If you would like to connect the Meter Connection Box to a bi-directional meter, make sure
that the bi-directional meter has galvanically isolated S0 interfaces.
Information on the Energy Meter LEDs
The energy meter's S0 LED only outputs the pulse value half as fast as the energy meter's
pulse LED.
Do Not Use the Meter Connection Box's Meter Pulses for Billing Purposes
You cannot use the meter pulses recorded by the Meter Connection Box to prepare
electricity invoices for the responsible electric utility company. The meter pulses of the
respective energy meter are still critical for electricity invoicing purposes.
Permissible Number of Devices:
• You can connect a maximum of 1 Meter Connection Box to 1 energy meter.
• You can connect a maximum of 3 Meter Connection Boxes to 1 Sunny WebBox.
Only use the Meter Connection Box exclusively for the purposes described in this manual. The
warranty becomes void if the Meter Connection Box is opened or modified.
The Meter Connection Box is intended for private and industrial use. Only use the Meter Connection
Box in the field of application specified in the technical data. Carefully read this manual before you
commission the Meter Connection Box. Keep this manual in a convenient place for future reference.
