MPPT Solar Controller w/ Remote Monitor and 7 Port Gigabit Passive PoE Switch

V2+ 48V 20A MPPT Smart Temp Comp Solar Charge Controller w/ 7 Port GigE Passive PoE Switch/Remote Monitor

The newest in our TPDIN series of products is the TPDIN-SC48-20 v2+. It is a web manageable MPPT Solar Controller with built-in 7 Port Gigabit Passive PoE switch. The controller uses temperature compensated smart battery charging to properly charge GEL or AGM or Lithium batteries and extend their life. It has a balance charge mode for periodic battery bank maintenance and can charge batteries that are dead. There are 4 Gigabit 802.3at or 24/48V Passive PoE and 3 Gigabit 24/48V Passive PoE ports. Each port is capable of 0.645A Max. There is a wire terminal auxiliary output capable of 2.25A maximum. 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), 48VDC, 24VDC or OFF through the web interface. 

The web interface has full capabilities to measure and log battery voltage, battery current, input voltage/current, load current and battery temperature. Ports can be controlled by a settable ping watchdog to power cycle the port if communications to the unit are interrupted. Auxiliary port can be controlled by voltage or temperature 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 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 battery fuse are removable for easy maintenance. The controller can be mounted using the integral DIN rail mount bracket or using 2 mounting tabs.
