DTSD422-D Inverter

The DTSD422-D inverter is actually documented as a three-phase DIN-Rail type meter (model DTSD422-D) designed for monitoring and protecting energy installations in buildings, charging stations, photovoltaic installations, and commercial facilities. The device measures network parameters of three phases and allows for bidirectional energy measurements and basic protection and data acquisition.

Manufacturer: SOLARMAN — the device comes from the SOLARMAN smart meter series designed for energy management. The company offers high-accuracy measurement solutions with built-in communication, intended for use in residential, commercial, and industrial buildings.
