The Meter Connection Box SMA Solar Technology AG


2 The Meter Connection BoxThe 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.

*PV = photovoltaics

SMA Solar Technology AG Safety


3 Safety3.1 Appropriate UsageThe 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" (page 26)).

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.

Information on Sealed Energy MetersIf 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 MetersIf 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 LEDsThe 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 PurposesYou 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.
