Benefits SMA Energy Meter Emeter-20

A photovoltaic system is only as intelligent as the information you receive. The SMA Energy Meter it is the piece that provides the teams SMA the data of consumption, pouring and generation with the precision and accuracy necessary for energy management to work stably. Integrating it in the installation guarantees, according to the manufacturer, a perfectly coordinated configuration offered maximum performance, greater stability, more savings and a superior self-consumption.

Three-phase, bidirectional measurement and phase phase

The Emeter-20 calculates electrical values in a form exact and also in a way balanced, differenting at all times the energy that is bought to the network from which is poured. This rapid bidirectional reading is the basis for tasks such as the injection limitation, the battery management or the control of loads.

High frequency Ethernet communication

Unlike meters that use buses series, the SMA Energy Meter connects to local router via Ethernet and share your data with all equipment SMA of the network. With a measuring cycle of 1000 ms and one 1% accuracy, the inverters they receive updated information every second to execute the control tasks with stability.

Registration of the generation of others inverters

In addition to measuring the connection point, the Energy Meter can communicate to systems SMA the photovoltaic generation of inverters of other manufacturers. It is especially useful in extensive installation extensions or in systems with several inverters, where you want to centralize all the information in Sunny Portal.

Independent of the company counter

The meter works independently of the existing counter, so it can be installed in any home or business without depending on the type of accountant of the distributor.

Installation plug-and-play in the electrical panel

With a 70 x 88 x 65 mm compact housing and a width of 4 dIN modules, the SMA Energy Meter is mounted on the electrical box of housing or in the counter without occupying just space. The start-up is plug-and-play: enough to wire the phases, connect it to the router by Ethernet and add it to the system. Their 2 State LED they allow you to check at a glance that the equipment works and communicates correctly.

For installations up to 63 a per phase it connects directly with cables 10 to 16 mm². If the installation exceeds the 63 A, the meter admits external current transformers, which allows you to use it also in shops, ships and industrial facilities.

Applications in self-consumption with storage

The Energy Meter is a key component in systems SMA with lithium batteries. By knowing in every second the balance between generation and consumption, the system can charge the battery with surplus instead of pouring them and download it when the house needs it, maximizing self-consumption. It also allows to apply injected power limitation or zero in facilities without surplus compensation.

Combine it with inverters hybrid or with inverters networking of SMA to get a complete solution of monitoring and energy management.

Monitoring in Sunny Portal and Local Web

The measured values are displayed graphically both in Sunny Portal, the online monitoring platform of SMA, as in the local web interface of the team. Thus, the user can consult in real time how much energy its installation of solar panels, how much consumes and how much exchanges with the network.

Frequently Asked Questions (FAQ)

1. The SMA Energy Meter serves for single-phase installations?

Yes. Although it is a meter three-phase, , SMA indicates that it can also be used in systems single-phase.

2. What happens if my installation exceeds 63 a per phase?

Direct connection supports a limit current of 63 A per driver. For upper currents, the meter connects by external current transformers, which allows you to use it in trade and industrial facilities.

3. How do you communicate with the inverter?

It connects to local network router by ethernet cable with RJ45 connector (10/100 Mbit / s) and share your data with the equipment SMA connected to that same network.

4. Do I need the Energy Meter to install a battery with a inverter SMA?

In storage systems SMA, the meter provides consumer and poured data that the system needs to manage the battery charge and unloading. Consult with our team the concrete configuration according to your model inverter and lithium battery.

5. Can I see the meter data on your mobile or computer?

Yes. The measured values are shown graphically in Sunny Portal and in the local web interface of the meter.
