temperature protection lower than the Low Temperature Protection Threshold (LTPT), the
controller stops charging and discharging automatically. When the
detected temperature exceeds the LTPT, the controller resumes work
automatically. (The LTPT is 0 °C by default and can be set within 10 ~
-40 °C. Detail settings refer to the LTPT V1.0.)
Controller Overheating
★
An internal temperature sensor can detect the internal temperature of
the controller. The controller stops working when the internal
temperature exceeds 85
℃
and resumes work when the internal
temperature is below 75
℃
.
TVS high voltage
transients protection
The controller's internal circuitry is designed with Transient Voltage
Suppressors (TVS), which can only protect against high-voltage surge
pulses with less energy. Suppose the controller is to be used in an area
with frequent lightning strikes. In that case, it is recommended to install
an external surge arrester.
★
When the control's internal temperature is 81
℃
, the reducing power charging mode is turned on, reducing
the charging power by 5%,10%,20%, and 40% for every increase of 1
℃
. If the internal temperature is greater
than 85
℃
, the controller stops charging. When the internal temperature is not more than 75ºC, the controller
will resume charge as per the rated power.
