The SolBrid: Extra flexible new Steca inverter for up to 4 PV strings

Future-proof, thanks to flexible PV input ports

“The SolBrid provides installers with a particularly flexible solution for a multitude of system variants, including complex roof layouts, different module and battery types, and standby power supply. The new inverter covers a wide range of applications,” says KATEK’s Dr. Peter Grabs.

Depending on the product variant, two or four MPP trackers enable a maximum photovoltaic input current of 15 Ampere each and an input voltage of up to 1,000 Volts. The first unit of the product range has an output of 10 kW.

App control and variable interfaces

Installation of the new inverter is possible via an app and users can access the operating data via mobile device. As a result of its IP65 standard housing, the inverter can also be installed outdoors.

A battery management system for BYD storage systems and an RS485 interface have been integrated (with further storage systems to be added). The RS485 enables the StecaGrid Switch circuit breaker and additional energy meters to be connected.

StecaGrid Switch for even more functions

Installing the StecaGrid Switch together with the SolBrid adds even more functions: The intelligent circuit breaker enables emergency power operation as well as real time measurement of energy consumption with deviation rate of just 2%, for accurate monitoring.
