XTRA Series


The XTRA-N series can display various display units (XDB1 / XDS1 / XDS2). The series includes a water-repellent housing (design) with protection class IP32.

With the new XTRA-N series, the reliability of the devices has again been significantly improved, so they meet the most varied of application requirements.

With MPPT (Max Power Point Tracking) the full power of your solar modules is optimally used.

For all common module technologies, ideal for solar systems with module voltages that are higher than the battery voltage. You can also use modules with these controllers that are actually intended for use in grid-connected systems.

The most efficient working point of the solar modules changes due to various factors, such as module temperature, irradiation, module type, etc. This working point is constantly monitored by the internal microcontroller and, if necessary, controlled so that the optimum performance of the solar module is given and your batteries are charged with the highest current.
