TPDIN-SC48-20 MPPT Solar Controller

Tycon Systems' TPDIN® series of products includes the TPDIN-SC48-20, a web-manageable MPPT solar controller with a built-in 7-port Gigabit passive PoE switch. The controller uses temperature-compensated smart battery charging to properly charge GEL, AGM, or lithium batteries and extend their life. It has a balance charge mode for periodic battery bank maintenance and can charge dead batteries. There are four Gigabit 802.3at or 24 V/48 V passive PoE and three Gigabit 24 V/48 V passive PoE ports. Each port is capable of 0.645 A max. There is a wire terminal auxiliary output capable of 2.25 A maximum. The total from all outputs is set at 150 W at 48 V_DC and 72 W at 24 V_DC for a max total of 222 W. Outputs can be switched by the user between 802.3at (port 1-4 only), 48 V_DC, 24 V_DC or OFF through the web interface.

The web interface can fully 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. An auxiliary port can be controlled by voltage, temperature, or time so it can be programmed to control lights, pumps, generators, heaters, fans, and others. The unit supports automated email alerts if user-programmed limits are exceeded so users 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 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 fuses are removable for easy maintenance. The controller can be mounted using the integral DIN rail mount bracket or two mounting tabs.
