Condition 4: Actual charging current of the PV array＞Rated charging current of the controller
When the controller operates under "Condition 3" or "Condition 4," ，it will carry out the charging as per
the rated current or power.
The controller may be damaged when:
1. The PV module's power is greater than the rated charging power.
2. The PV array's maximum open-circuit voltage is more than
CAUTION
60(Tracer**06AN)/100V(Tracer**10AN)(at the lowest environmental temperature).
According to the "Peak Sun Hours diagram," if the PV array's power exceeds the controller's rated
charging power, the charging time as per the rated power is prolonged. The controller can obtain more
energy. However, in the practical application, the maximum power of the PV array shall be not higher
than 1.5 times the rated charging power of the controller. Suppose the maximum power of the PV array
exceeds the rated charging power of the controller too much. In that case, it causes the waste of the PV
array, and increases the PV array's open-circuit voltage, which may increase the probability of damage
to the controller. For the recommended maximum power of the PV array, please refer to the table below:
