Solarix PLI

Solarix PLI

5000-48 Rev 2, 2400-24

The Steca Solarix PLI is the first product from KATEK Memmingen to offer an all-in-one package. It allows users to supply loads with 230 V AC power, charges the battery with an integrated MPPT charge controller, and at the same time allows connection to a generator.

Everything in a single device.

This means that solar energy can be used as the top priority. And if that isn’t enough, a generator can be started by the Solarix PLI. At the same time, the battery can also be recharged by either the PV or the AC input source. Given its very quick switchover time of up to 10 ms and its flexible energy priority selection, the Solarix PLI also acts as an uninterruptible power supply.

Even difficult consumers, such as large AC motors, can be started reliably with double overload capacity. The maximum power point tracker in the integrated charge controller ensures that, even in difficult lighting conditions, the maximum output is obtained from the PV modules in order to optimally charge the battery and supply the consumers with power at the same time.
