STECA TAROM 4545-48 Solar Charge Controller 12/24/48V 45A

STECA TAROM 4545-48 Solar Charge Controller – 12/24/48V 45A

The STECA TAROM 4545-48 sets new standards in its power class, supporting three voltage levels: 12V, 24V, and 48V. A graphic display informs users about all of the important system data, stored by the integrated data logger. Based on the significantly improved state of charge calculation, regulation of the system is optimal and the batteries are protected. The best choice for larger systems. Two additional switching contacts can be freely configured as a timer, night light function, for starting generators or as a surplus manager.
