ADDITIONAL INFO:
Lithium battery
low temperature
protection
When the temperature detected by the optional temperature
sensor is lower than the Low Temperature Protection
Threshold(LTPT), the controller stops charging and discharging
automatically. When the detected temperature is higher than the
LTPT, the controller resumes work automatically. (The LTPT is
0 °C by default and can be set within the range of 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°C and resumes work when
the internal temperature is below 75°C.
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°C, the reducing power
charging mode is turned on, reducing the charging power of 5%, 10%, 20%,
40% every increase of 1°C. If the internal temperature is greater than 85°C,
the controller stops charging. When the internal temperature is not more
than 75°C, the controller will resume charge as per the rated power.
