Sinus Inverter for PV self-sufficient systems

Steca PLI-300
The Steca PLI-300 is a cost-effective 300 W sine wave inverter that can power small AC loads. It has a manual on / off switch that can be used to shut down the inverter and prevent self-consumption. The device is particularly suitable for solar home systems, in which, in addition to the DC consumers, small AC loads are switched on manually as required. The device is supplied with DC cables and has a European AC junction box.

Steca Solarix PI
During the development of the sine wave inverter Steca Solarix PI, a number of innovations were realized that did not exist before in this form. Particularly noteworthy here are the parallel connection, the novel control concept via a single rotary switch, the direct communication for calculating the state of charge (SOC) with Steca Tarom and Steca Power Tarom and the electronic fuse. In addition, our many years of experience for special use in photovoltaic systems have also been incorporated. This is reflected, among other things, in the stable supply of a wide range of devices and low self-consumption.

Steca AJ
The Steca AJ inverter series is characterized mainly by its variety of available power classes and different DC input voltages.
Thus, the optimal inverter can be selected for each application. The cables for connecting the battery and the consumer are already pre-assembled on the Steca AJ and facilitate the installation of the device. The automatic standby mode significantly reduces the self-consumption of the inverter. The excellent overload capacity of Steca AJ inverters ensures that even critical loads can be operated without any problems.

Steca XPC
The devices of the Steca XPC series combine a very high overload capacity with the ability to operate even very critical loads.
The convincing device protection and low self-consumption are further important features of this high-quality inverter. The Steca XPCs combine a sine wave inverter, a four-stage battery charger and a transfer system in one device, making them ideal for hybrid systems. The built-in auxiliary auxiliary contact allows z. B. Turn on and off surplus consumers or start a diesel generator to recharge the battery.

Steca Xtender XTS
The basic features of the Steca Xtender series inverter are the inverter, battery charger, switching function and support for external AC power sources. These functions can be combined and controlled completely automatically, offering exceptional ease of use and excellent utilization of the available energy.
The Steca Xtender XTS can be completely adjusted via the remote control. If software with new features is available, it can be transferred to the system so that the Steca Xtender XTS is always up to date. Several Steca Xtender XTS can be connected in parallel and in three phases. This allows up to nine Steca Xtender XTS to work together.

Multifunction contacts
These floating contacts can be programmed for many different applications. You can respond to any event outside or inside the inverter (grid availability, battery voltage, fault message ...). They are also programmable as timers or can be switched during certain times (at night, on weekends ...). Thus, they can serve as a generator starting device, for switching off less important consumers, for displaying a fault, for situation-dependent battery charging, etc.

Function Smart-Boost
The Smart Boost function can increase the power of another AC power source, such as a generator or shore power. Even if they are special loads (inductive, asymmetrical, high inrush current). You can also combine the Steca Xtender XTS with almost any existing inverter to increase the available power.

StecaGrid 8000+ 3ph and StecaGrid 10000+ 3ph
The advantage of the three-phase infeed is that the solar power produced is always distributed symmetrically on all three network conductors to the public power grid. This is the case for these inverters over the entire power range. In the case of plant design, this eliminates the sometimes costly avoidance of an asymmetry of more than 4.6 kW through the corresponding selection of individual inverters. The symmetrical feed is very much in the interest of the energy supply companies. Lengthy discussions with them are a thing of the past.

StecaGrid 20000 3ph - 23000 3ph
The three-phase StecaGrid inverters are ideally suited from commercial rooftop systems to megawatt parks. With an output voltage of 460 V and an input voltage range of 575 V to 850 V, the StecaGrid 23000 3ph is the ideal player for medium-voltage applications in large-scale PV systems.
The devices meet all requirements of protection class IP 65: Their housing reliably protects them from dust and water. The inverters can thus be easily installed outdoors.
