★When the internal temperature is 81℃, the reduce charging power mode which
reduce the charging power of 5%,10%,20%,40% every increase 1 ℃ is turned on. If
the internal temperature is greater than 85℃, the controller will stop charging.
When the temperature declines to be below 75 ºC, the controller will resume.
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).
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).
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.
The internal circuitry of the controller is designed with Transient
Voltage Suppressors (TVS) which can only protect against high-volt-
age 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.
