Battery polarity
reverse
connection
When the polarity of the battery is reversed, the controller will not
work and will not be damaged. After correcting the wiring error, re-open
the opportunity to continue normal operation.
Battery over
discharge
protection
When the battery voltage is lower than the set undervoltage value,
the discharge of the battery will be automatically stopped to prevent the
battery from being over-discharged and damaged.
Battery
overload
protection
When the controller output current is greater than the set value, the
load output will be automatically stopped to prevent the battery from
being over-discharged and damaged.
Battery over
volatge
protection
When the battery voltage reaches the overvoltage protection setting
value, the battery will be automatically stopped to prevent the battery
from being overcharged and damaged.
Night anti-
reverse
protection
At night, since the battery voltage is greater than the voltage of the
photovoltaic module, the automatic protection prevents the battery
voltage from being discharged through the photovoltaic module;
Equipment
overheat
protection
The controller has its own temperature sensor. When the
temperature is higher than the set value, the charging will stop. When the
temperature is lowered, it will automatically start to work.
High voltage
surge
This controller can only protect high-voltage surges with low energy.
In areas with frequent lightning, it is recommended to install an external
lightning arrester.
