12/24V In 12/24V out, 20A solar in MPPT Battery Charging Controller (TP-SC24-20-MPPT)


Item# TP-SC24-20-MPPT

The Tycon Solar™ TP-SC24-20-MPPT solar controllers are MPPT (Maximum Power Point Tracking) temperature compensated battery charging controllers. The battery temperature probe cable is included. The controllers are auto-ranging to accommodate 12V and 24V battery systems. They are designed to charge Flooded, AGM, GEL or Lithium batteries. They also have a USER setting for customizable battery charge settings. They have an integral LCD display that shows Battery Voltage, Battery Capacity, Charging Capacity, Battery Temperature, Load Current and Solar Current.

There is an RS232 interface to connect to the Tycon #TP-SC-BT1 Bluetooth adapter (not included). Using this configuration and the available Android or IOS mobile app, the solar controller can be monitored and controlled from a distance.

They have multiple load operating modes which can be set through the buttons on the controller.

The load output has a soft start feature so it can smoothly and reliably power up high capacitance loads up to 20A. There is a convenient On/Off button to disconnect load power when the unit is operated in the default mode (15).

They have full electronic protections for short circuit, reverse current, over-power, over-voltage, over-charge, overdischarge and over-temperature. The built-in over-discharge protection and low self consumption ensures the battery is not over-discharged, which greatly increases the life of the batteries. All protections are auto-recovery.

The units are protected against lightning strikes with TVS diode protection. They operate over a wide industrial temperature range. Electronics are conformal coated for environmental protection.

An automatic battery equalization charge automatically engages once every 30days (Programmable). The equalization charge helps to balance the batteries in an array and reduce the possibility of battery sulfation.

Connections are via 6 screw terminals for wire size up to 10AWG. The controllers are internally fused for protection, but we recommend always using an external 20A fuse between the controller and the battery. There are four screw holes for wall mounting. In addition, there are two DIN Rail brackets for DIN Rail mounting included.
