StecaGrid SEM
Smart Energy Manager for coolcept, coolcept-120, coolcept-x, StecaGrid 8000+ 3ph and 10000+ 3ph The feed-in management solution In Germany, photovoltaic systems require feed-in management. To this end, ripple control receivers of the respective grid operators are installed. These ripple control receivers transmit a reduction signal from the grid operator whenever the system has to be throttled due to grid overloads. StecaGrid SEM is the easiest way to connect your StecaGrid inverter to the ripple control receiver. StecaGrid SEM evaluates the relay outputs of the ripple control receiver and transmits the signals via the Steca solar bus (or Steca RS485 bus) to the connected inverters. SEM stands for Smart Energy Manager Easiest installation StecaGrid SEM can be installed in the switching cabinet right next to the ripple control receiver. The casing features a dimensioning typical for switching cabinets and can be mounted onto a top-hat rail. Its width is 4 HP. Direct power supply at 230 V. A mains adapter plug or an external direct current power supply are not required. Easily accessible service interface All connected StecaGrid inverters can be accessed via a USB interface on the StecaGrid SEM. Connection to a PC is possible via a standard USB cable. The interface is on the front side of the casing – the cover does not need to be removed in the switching cabinet. Other functions As of firmware version 3.x, StecaGrid SEM offers additional functions: data can be read from an energy meter via a S0 interface. This allows for a distinction between the share of PV energy used at home and that fed into the grid. With this measurement data, StecaGrid SEM monitors the house connection and ensures that no more than 70% of the system‘s output is fed into the grid. If required, it accurately reduces the output of the connected inverters.

StecaGrid Portal
Free web portal for system monitoring Plug and Play When the Ethernet interface of the coolcept inverter is connected to a router, the data from the data logger of the inverter is sent directly to the StecaGrid Portal. Setting up the portal is easy: Follow the link below to the system data entry mask. In addition to system output, the modules used and the location of the system, the serial numbers of the installed inverters are queried. On the StecaGrid Portal, up to 5 coolcept* and coolcept-x inverters can be combined to one system. The data of the individual devices are added up and displayed as a complete system. Free use for two years If the system operator agrees to having his system data published on www.solare-energiewende.de, the StecaGrid Portal (offered in collaboration with meteocontrol) can be used free of charge for two years. Afterwards for further optional use, which is not free of charge, he will receive an offer. Clear presentation of yield data The software interface is very clearly structured. In addition to the system data, yield data is displayed in daily, weekly, monthly and annual profiles. A scale evaluates current yield data of the system in comparison to values from other systems in the same region. This allows the user to determine at a glance whether the system‘s yield lies above or below the regional average. The display also shows the user‘s environmental contribution in terms of CO2 saved due to yields. Smart networking Monitor the output of your PV system for free with the StecaGrid Portal. With the intuitive user interface, you can access your yield data anywhere and at any time – even from your smartphone or tablet PC.

StecaGrid 8000+ 3ph and StecaGrid 10000+ 3ph
Always symmetrical the advantage of three-phase feeding is that the produced solar capacity is always symmetrically distributed on all three power conductors to the public power grid. This is the case across the whole output range offered by these inverters. When designing a system, the laborious avoidance of an asymmetry of more than 4.6 kw through the appropriate selection of separate inverters is thus dispensed with. Symmetrical feeding is greatly in the interests of energy supply companies. Lengthy discussions with such companies are therefore a thing of the past. long service live while the voltage passes through zero on the grid-feeding phase, single-phase inverters must temporarily accommodate all energy supplied by the solar modules within the device. This is usually realised by electrolytic capacitors. These components influence the service life of an electronic device, due to the possibility of drying out. With three-phase inverters, energy is fed into the grid on at least two phases at all times. Thus, the necessity of intermediate storage of energy in the device is greatly reduced, which is of benefit to the system operator with regard to a longer service life.

All the settings of the Steca Xtender XTS can be remote controlled. When a software with new functions is available, it can be loaded into the system, so the Steca Xtender XTS always stays up to date. Several Steca Xtender XTS can be connected in parallel or to form a three-phase system. That means that up to nine Steca Xtender XTS can work together. Multifunction features These potential-free contacts can be programmed for many different applications. They can react to any event outside or inside of the inverter (grid availability, battery voltage, fault message ...) They can also be programmed on a timer or can be switched on during particular times (at night, at the weekend ...). In this way, they can serve to start up a generator, to switch off less important loads, to signal a fault, to charge batteries depending on the situation, etc. Smart-boost function With the smart-boost function, the output of another source of alternating current, such as a power generator or a land connection, can be increased; even when special loads are being used (inductive, asymmetric, with high switch-on current). It is also possible to combine the Steca Xtender XTS with almost all inverters which are already present in order to increase the available output.
