Overtemperature protection The solar charge controller records the internal temperature via
the internal sensor. If the temperature exceeds the set value, the
charging current will decrease, and consequently the
temperature of the solar charge controller.
Should the temperature of the solar charge controller and
approach the temperature protection threshold, the solar charge
controller will stop operating. It restarts the process when the
temperature has dropped again or returned to an acceptable
level.
Load overcurrent protection When the load current exceeds the maximum factor of 1.25,
the solar charge controller disconnects the load.
Should the temperature sensor short circuit or
Caused
Short-circuit protection Once a load short-circuit occurs, the load will short-circuit while
charging
Description
Damaged
remote temperature sensor damaged, the solar charge controller automatically adopts the
internal temperature. This prevents the battery from being
overcharged or discharged.
circuit protection triggered automatically.
Battery overvoltage If there are other energy sources charging the battery when the battery
voltage exceeds 15.8 / 31.3 / 46.8 / 62.3 V, the solar charge
controller will stop the charging process to protect the battery
from overcharging to protect against damage. (Lithium battery
overcharge protection voltage is equal to target voltage plus
0.2V.)
Battery over-discharge When the battery voltage drops to low-voltage cutoff, the solar
charge controller will stop discharging to protect the battery
from over-discharge damage.
