4 Product Overview SMA Solar Technology AG
By installing the SMA RS485 Module, the inverter is able to communicate with the energy meter of
the SMA Revenue Grade Meter Kit.
Class 1 wiring methods are to be used for field wiring connection to the terminals of the
communication interface.
Antenna Extension Kit
Within the WLAN network, the Antenna Extension Kit enables the radio range of the inverter to be
upgraded (Information on assembly and connection see manual of the Antenna Extension Kit). The
Antenna Extension Kit can be retrofitted.
SMA Cellular LTE Modem Kit
The inverter can be retrofitted with the SMA Cellular LTE Modem Kit from firmware version
03.01.24.R.
The SMA Cellular LTE Modem Kit allows the direct data transmission between the inverter and the
internet portal Sunny Portal powered by ennexOS via the cellular network as an alternative to data
transmission via Ethernet or WLAN. In addition, the SMA Cellular LTE Modem Kit enables the
communication between the inverter and the energy meter. The energy meter is a so called PV
production meter intended to measure the generated energy of the inverter.
The SMA Cellular LTE Modem Kit transmits up to four times a day a limited amount of data to
Sunny Portal powered by ennexOS. The standard term of the mobile data plan for the
SMA Cellular LTE Modem Kit is five years. All costs are covered within the term. No additional
costs will be incurred. You have the possibility to extend the term of the mobile data plan. For this
purpose, contact SMA Solar Technology AG. By using the SMA Cellular LTE Modem Kits, a local
network connection is not absolutely necessary. However, it is recommended to be able to view all
information regarding the system in Sunny Portal powered by ennexOS.
Energy meters in accordance with ANSI C12.20
The inverter can be retrofitted with the SMA Revenue Grade Meter Kit that in accordance with
ANSI C12.20 includes an energy meter.
The energy meter fulfills the accuracy class 0.5 in accordance with ANSI C12.20. The energy
meter is a so called PV production meter intended to measure the generated energy of the inverter.
The measured values of the energy meter can be used for billing purposes.
Grid Management Services
The inverter is a grid support interactive inverter.
The inverter was tested in accordance with the UL 1741 SA (2016-09-07) to be compliant with the
source requirements documents of the states available at the time. For connecting the inverter to the
utility grid, no additional grid monitoring equipment is necessary. A description of the tested
functions and instructions on the activation and setting of functions can be found in the technical
information "Grid Support Utility Interactive Inverters" at www.SMA-Solar.com.
PV Rapid Shutdown Equipment
The inverter is listed as PV Rapid Shutdown Equipment (PVRSE) according to UL 1741.
All DC inputs and AC outputs of this product comply with photovoltaic rapid shutdown requirements
for controlled conductors outside the array.
