battery damage caused by over-discharging. (Any controller connected loads will be disconnected. Loads directly connected
to the battery will not be affected and may continue to discharge the battery.)
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 ~
-40 °C).
Load Short Circuit
When the load is s
hort 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).
Controller Overheating
★
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 arrester.
