Battery
Overheating
The controller can detect the battery temperature through an external temperature sensor. The
controller stops working when its temperature exceeds 65 °C and restart to work when its
temperature is below 55 °C.
Lithium Battery
Low
Temperature
When the temperature detected by the optional temperature sensor is lower than the Low
Temperature Protection Threshold(LTPT), the controller will stop charging and discharging
automatically. When the detected temperature is higher than the LTPT, the controller will be
working automatically (The LTPT is 0 °C by default and can be set within the range of 10 ~ -
Load Short
Circuit
When the load is short circuited (The short circuit current is ≥ 4 times the rated controller load
current), the controller will automatically cut off the output. If the load reconnects the output
automatically five times (delay of 5s, 10s, 15s, 20s, 25s), it needs to be cleared by pressing the
Load button, restarting the controller or switching from Night to the Day (nighttime > 3 hours).
Load Overload
When the load is overloading (The overload current is ≥ 1.05 times the rated load current), the
controller will automatically cut off the output. If the load reconnects automatically five times
(delay of 5s, 10s, 15s, 20s, 25s), it needs to be cleared by pressing the Load button restarting
the controller, switching from Night to Day (nighttime > 3 hours).
The controller is able to detect the temperature inside the battery. The controller stops working
when its temperature exceeds 85 °C and restart to work when its temperature is below 75 °C.
TVS High
Voltage
Transients
The internal circuitry of the controller is designed with Transient Voltage Suppressors (TVS)
which can only protect against high-voltage surge pulses with less energy. If the controller is to
be used in an area with frequent lightning strikes, it is recommended to install an external surge
