4.4 Temperature Sensor (Optional)
When an external temperature sensor (optional accessory) is installed, the controller will adjust
the Bulk and Float Charge Voltage according to the temperature of the battery type. The
regulation setpoint is 25ºC. The Controller adjusts the BULK and FLOAT setpoints -0.03V/ ºC.
Only the factory provided temperature sensor (optional accessory) can be used.
If no temperature sensor is installed, the controller will set the temperature of the battery at 25ºC.
4.5 Over Temperature Protection
The operation temperature of the transistors of the PV Charge Controller is also continuously
monitored. If excessive temperature is detected, the charge controller transistors will repeatedly
and rapidly turn On and Off to reduce the charging rate so as to reduce the transistors'
temperature. In case the charging current (from the solar panel) is reduced to zero and over
temperature condition still persists, the load will also be disconnected.
When the temperature has dropped to the working range, the PV panel and the load will be
connected again.
5. Remote Signal Terminal (Optional)
The PV controller has a remote signal output terminal (Optional) which can:
1. control the ON/OFF operation of equipment such as inverter hooked up to the battery bank to
operate along with the night-light mode program and share the safeguard function such as
low battery disconnect and reconnect.
2. make extension connection of the battery status LED to allow remote monitoring Battery
bank status (see Section 3.2)
