The TPDIN-SC48-20 is a web manageable MPPT Solar Controller w/ built-in 7 Port Gig Passive PoE switch. The controller uses temp compensated smart battery charging to properly charge GEL, AGM or Lithium batteries. It has a balance charge mode for periodic battery bank maintenance. There are 4 Gig 802.3at or 24/48V Passive PoE and 3 Gig 24/48V Passive PoE ports. Each port is capable of 0.645A Max. 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 for a max total of 222W. Outputs can be switched by user between 802.3at (port 1-4 only), 24/48VDC or OFF through the web interface.
The web interface has full capabilities to measure and log batt voltage, current, temperature, input voltage/current, and load current. 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, temp or time. It can be programmed to control lights, pumps, generators, heaters, fans, etc. The unit supports auto 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 connected to the PV+/PV- input in order to charge the batteries from an AC source like grid power or generator.
All inputs and outputs are surge and overload protected. Connectors and batt fuse are removable for easy maintenance. The controller can be mounted using the integral DIN rail mount bracket or using 2 mounting tabs.
