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.
When not in the PV charging state, the controller will not be
damaged in the case of short-circuiting in the PV array.
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 the mis-wiring is corrected.
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 over charging.
When the battery voltage reaches the low voltage disconnect
voltage, the battery discharging is automatically stopped to
prevent battery damage caused by over discharging.
When a load is connected to the battery, 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℃.
