BATTERY OVER
TEMPERATURE
The controller can detect the battery temperature through an
external temperature sensor if fitted. The controller stops working
when its temperature exceeds 65 °C and restart to work when its
temperature is below 55 °C. NOTE: With an ambient temperature
sensor fitted, the unit will only stop charging if ambient
temperature exceeds 65°C
LITHIUM
BATTERY LOW
TEMPERATURE
When the temperature detected by the ambient 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 work automatically (The LTPT is 0 °C by
default and can be set within the range of 10°C ~ -40 °C).
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 the Day (night time > 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 or switching
from Night to Day (night time > 3 hours).
CONTROLLER
OVER
TEMPERATURE
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.
When the internal temperature is >81°C the unit will enter reduced
charging power mode which reduces the charging power by
5%, 10%, 20% and 40% for every increase of 1°C. If the internal
temperature exceeds 85°, the controller will stop charging. When
the temperature declines to below 75°C, the controller will resume
charging.
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.
