With the newly developed Stecagrid Solbrid, the Steca brand from the manufacturer Katek presents a particularly flexible and powerful three-phase hybrid inverter. It has ten kilowatts of power and up to four MPP trackers. This makes it suitable for photovoltaic systems on complex roofs.

The battery charging current of up to 25 amps also enables the connection of a wide variety of high-voltage batteries. In combination with the Stecagrid Switch, the inverter enables stand-alone operation when the electricity grid is not available. In this case, all consumers in the house can be supplied with emergency power from the solar system or the battery.

The two or four MPP trackers, depending on the product version, allow a maximum input current of 15 amps each and an input voltage of up to 1,000 volts.

The new inverter is installed via app, the operating data can be read out via mobile end devices. The IP65 standard means that the device can also be mounted outdoors. (mfo)
