4.1 Protections

Tracer AN series controllers have no battery reverse protection. Do not reverse the
battery during the wiring. Otherwise, the controller may be damaged.

When the PV array's actual charging current or power exceeds the
controller's rated charging current or power, the controller charges the
battery as per the rated current or power.
Not in the PV charging state, the controller will not be damaged when
the PV array short-circuits.
WARNING: It is forbidden to short-circuit the PV array during
charging. Otherwise, the controller may be damaged.
When the PV array's polarity is reversed, the controller may not be
damaged and resume work after correcting the mis-wiring.
CAUTION: If the PV array is reversed and its actual power is 1.5
times the controller's rated power, the controller may be damaged.
Prevent the battery from discharging to the PV module at night.
When the battery voltage reaches the over voltage disconnect voltage,
the PV array will automatically stop charging the battery to prevent the
battery damage caused by overcharging.
When the battery voltage reaches the low voltage disconnect voltage,
the battery discharging is automatically stopped to prevent battery
damage caused by over discharging.
CAUTION: When the battery connects with a load, and the load
is connected to the controller's (Load) dry contact, the battery
over-discharge protection takes effect.
The controller detects the battery temperature through an external
temperature sensor. The battery stops working when its temperature
exceeds 65℃ and resumes work when its temperature is below 55℃.
When the temperature detected by the optional temperature sensor is
