Benefits Fronius Smart TS 100A-1

The counter is the component that converts a inverter in a system of intelligent energy management. Without him, the inverter it produces blindly; with the Smart TS 100A-1, know at every moment how much energy the housing consumes, how much is taken from the network and how much is poured. That information is the basis for maximize self-consumption, load the battery at the right time and meet the injection limits.

Dynamic injection regulation faster than with an accountant S0

The great advantage over solutions with impulse output S0 is the digital Communication Modbus RTU on RS485. . Fronius indicates that, thanks to this interface and the high precision measuring, the dynamic control of the injected power is faster and more accurate that with an accountant S0. In practice, this translates into a finer fit when the distributor or regulation demand zero or a export limitation, reducing the risk of unwanted injections in the network.

Certified accuracy for a reliable energy balance

With Class 1 according to EN 62053-21 and Class B according to EN 50470-3 in active energy, in addition to Class 2 (EN 62053-23) in reactive, the TS 100A-1 offers reliable data to analyze the load curve and dimension extensions. Your start current of only 40 mA it allows to register even very low residual consumption, such as those of standby equipment.

Compact and efficient in the electrical panel

Barely 35.8 mm wide (2 DIN modules), fits without problems in residential checkered with little free space. Your own consumption of 1 W or less just penalizes the balance of the installation, and the range of -25 ° C to +65 ° C it guarantees stable operation in indoor frames subjected to thermal variations.

Keypiece in systems with storage

Combined inverters hybrid like Fronius Gen24 plus and with lithium batteries compatible, the Smart Meter TS coordinates the different energy flows: decide when to load, when to download and when to export. According to the manufacturer, this coordination optimizes complete energy management of the installation.

For what facilities is the Smart Meter indicated TS 100A-1?

The version 100A-1 is the variant single-phase from the Smart Meter range TS. Is the right choice for housing and small businesses with supply single-phase at 230 V and a current that does not exceed the 100 A, admitting power cables up 25 mm². For supplies three-phase, , Fronius offers the versions TS 65A-3 (up to 3 x 65 a) and TS 5ka-3 (for great intensities with transformers.)

It is especially recommended in:

• Self-consumption facilities with inverters networking Fronius must pouring limitation.
• Hybrid systems with batteries, where the measurement at the network connection point is essential to manage the loading and unloading.
• Extensive installation extensions: The counter can be added at any time along with the Fronius Datamanager 2.0 on inverters already installed.
• Complete projects of solar kits in which a detailed monitoring of consumption is sought.

Monitoring Fronius Solar.web

In combination with Fronius Solar.web, the Smart Meter TS presents a clear view of electricity consumption of housing. The user can consult the production of his solar panels, the consumption of the house and the exchange with the network. This allows identify optimization opportunities of the photovoltaic system and supervise and analyze the higher consumption loads, as air conditioning, electrical thermos or recharge points.

Connecting scheme

The manufacturer's configuration scheme places the counter in the connection point with the network, between the inverter and the consumption of the house on the one hand and the rush on the other:

1. The photovoltaic generator feed inverter Fronius.
2. The output of the inverter (single-phase in the case of TS 100A-1) feeds the domestic consumption.
3. The Smart TS it is installed between that line and the power grid, measuring the flow in both directions.
4. The counter communicates with the inverter through Modbus RTU (RS485).

On Tienda Solar we advise you to choose the appropriate accountant to your inverter and your type of supply, and in the Blog Tienda Solar you will find purchase guides, installation tips and technical articles developed by experts in photovoltaic energy.

Frequently Asked Questions (FAQ)

1. The Fronius Smart TS 100A-1 serves for a three-phase installation?

No. The model TS 100A-1 it is single-phase (230 V, 1 x 100 a). For supplies three-phase the Smart TS 65A-3 (up to 3 x 65 a) or the TS 5ka-3 for high intensities.

2. With what inverters is it compatible?

Fronius recommends it for inverters Gen24 plus and Taurus, as well as for all inverters solar Fronius equipped with Datamanager 2.0. Communication is done through interface RS485 with Protocol Modbus RTU.

3. Do I need the smart to apply zero pouring?

To make a dynamic injection limitation, the inverter you need to know in real time the flow at the network connection point, and that measure is provided by the counter. With the Smart Meter TS the regulation is faster and more precise than with an accountant S0, thanks to Modbus RTU communication.

4. Can I install it in a photovoltaic installation that is already working?

Yes. According to the manufacturer, the Smart Meter can be incorporated at any time along with the Fronius Datamanager 2.0 on inverters they are already installed, which facilitates adding consumption monitoring or battery below.

5. What cable section does it admits and how much space occupies in the box?

Supports power and neutral cables 1 to 25 mm² and communication cable 0.05 to 1.5 mm². Occupies 2 modules DIN 43880, with dimensions of 91.5 x 35.8 x 63.0 mm, and it is mounted on dIN rail indoors.

6. Can it be installed abroad?

Not directly. The specific manufacturer iNTERIOR MOUNTION (DIN rail) with protection IP51 on the front and IP20 on terminals, so you must stay within an appropriate electrical panel.
