5.1.11 Over Temperature Protection – Battery
Battery over temperature protection is activated at > 65° and is
reset automatically
when the
temperature drops to < 55°C. When Battery Over Temperature Protection is activated, the Bat-
tery Status LED (
2, Fig 2.1
) will slowly blink Red (
1 Hz
) and charging will stop.
For accurate temperature sensing of battery temperature, optional Temperature Sensor Model
MSK-TS is required to be installed on the battery and connect to the Temperature Sensor Port on
the Controller (
See Section 3.4.4.
4).
If the above optional Temperature Sensor Model MSK-TS is not used, Temperature Sensor inside
the controller (
used for measuring controller temperature
) is used for indirect and approximate
sensor of battery temperature (
provided the controller is place very close to the battery)
used, the
above trigger temperature of 65°C will be the
actual
battery temperature.
When battery temperature sensing is being done
indirectly
by sensing the internal temperature
of the controller the built-in temperature sensor, this trigger temperature of 65°C will be tem-
perature inside the controller.
When optional Temperature Sensor Model MSK-TS is used, the above trigger temperature of
65°C will be the
actual
battery temperature.
5.1.12 Over Temperature Protection – Controller
If the temperature of the controller’s heat sink exceeds 85°C, the input and output will be dis-
connected. The following 3 LEDs will blink:
• Solar Panel Status LED (
Fig 1, 2.1
) will blink Green
• Battery Status LED (
2, Fig 2.1
) will blink Orange
• Load Status LED (
3, Fig 2.1
) will blink Red
Input and Output connections will be restored at 75
°
C
5.1.13 Damaged Temperature Sensor
If the optional external battery temperature sensor Model MSK-TS (
Section 3.4.4
) is short-circuit-
ed or damaged, the controller will charge or discharge at the default temperature of 25°C.
5.1.14 System Error Voltage
If the battery voltage does not match the controller's battery input voltage specifications of
8-32V, the operation of the unit will be stopped due to "System Error Voltage". This condition
will be indicated as follows (Refer to Table 4.1 under Section 4.5):
• Solar Panel Status LED (
Fig 1, 2.1
) will blink Green
• Battery Status LED (
2, Fig 2.1
) will blink Red
• Load Status LED (
3, Fig 2.1
) will blink Red
Ensure that the battery voltage is within the acceptable range of 8-32V. Press Load On/Off But-
ton (4, Fig 2.1) to clear the fault.
5.1.15 High Voltage Transients
Battery is protected against high voltage transients. In lightning prone areas, additional external
lightning protection is recommended.
