Extensive load and energy management

The x2 functions for energy management combined with the energy meter CAN-EZ3 and power controllers allow many options for optimizing private power consumption of PV systems, as well as effective load management and targeted usage of excess power.

Mehr und mehr Technik

Wallboxen ebenso wie Stromspeicher halten zunehmend Einzug in Ein- und Mehrfamilienhäuser. Um den eigenen Strom der PV Anlage sinnvoll nutzen - oder "verteilen" - zu können, benötigt man eine intelligente Steuerung.

Tagesgeschäft: Hybride Heizungen

Vor allem im Bestandsgebäude werden Wärmepumpen oft mit "konventionellen" Heizungen kombiniert. Eine Regelung dafür zu finden stellt sich oft schwierig dar. Oder auch nicht.

70% infeed rule

In Germany, according to the EEG, no more than 70% of the nominal power may be fed into the grid, e.g. 7 kW of a 10 kWp system. The x2 series lets you optimize your private consumption, such that ideally the inverter’s effective power limiter won’t be necessary. We’ll show you how [Link only available in German).

Power-to-Heat

2^nd example: ATON is a plug & play solution to use surplus PV energy – without additional wiring. It consists of an energy meter and an immersion heater, continuously controllable from 50W up to 3 kW, for mounting in a combi or buffer storage cylinder.

Wirelessly connected, the energy meter transmits the available power to the immersion heater. The immersion heater sends all measured values (HLCS, internal temperature and measurements of both external sensors) back to the energy meter.

Visualization & data logging

The C.M.I. (sold separately) allows end customers safe and easy access to settings, e.g. using a mobile app with readily prepared visualization.

Connect the C.M.I., upload the visualization and access it using a PC or mobile app. Connection to the internet is optional, not necessary.

conformity

Other commercially available solutions use phase angle control. Smart meters detect their short-term usage of power, which costs the consumer money.

The intelligent immersion heater of the ATON set has sinusoidal power consumption, which avoids the unnecessary and costly power consumption.
