The newest in our TPDIN series of products is the TPDIN-SC48-20. It is a web manageable MPPT Solar Controller with built-in 7 Port Gigabit Passive PoE switch. The controller uses temp compensated smart battery charging to properly charge GEL or AGM batteries and extend their life. It has a balance charge mode for periodic battery bank maintenance. There are 3 Gigabit Passive PoE+ 35W and 4 Gigabit Passive PoE 18W ports. There is a wire terminal aux output capable of 2.25A max. Total from all outputs is set at 150W at 48VDC and 72W at 24VDC. Outputs can be individually switched between 48V and 24V or OFF through the web interface.
The web interface has full capabilities to measure and log battery volts, battery current, input current, load current and battery temp. Ports can be controlled by a settable ping watchdog to power cycle the port if communications to the unit are interrupted. Aux port can be controlled by voltage or temp or time so it can be programmed to control lights, pumps, generators, heaters, fans, etc. The unit supports automated Email alerts if user programmed limits are exceeded so that the user can be alerted in case of developing problems at the site.
The controller can also be powered through an external AC to DC power supply in order to charge the batteries from an AC source like grid power or generator. The solar input of the controller always takes priority so if the sun is shining the external DC input isn’t used.
All inputs and outputs are surge and overload protected. Connectors and battery fuse are removable for easy maintenance.
