，Module Temperature 25℃， Air Mass1.5.
(2) Maximum PV array power
The MPPT controller has the function of current/power-limiting, that is, during the charging process, when
the charging current or power exceeds the rated charging current or power, the controller will automatically
limit the charging current or power to the rated charging current or power, which can effectively protect
the charging parts of controller, and prevent damages to the controller due to the connection of some over-
specification PV modules. The actual operation of PV array is as follows:
Condition 1:
Actual charging power of PV array ≤ Rated charging power of controller
Condition 2:
Actual charging current of PV array ≤ Rated charging current of controller
When the controller operates under “Condition 1”or“Condition 2”, it will carry out the charging as per the
actual current or power; at this time, the controller can work at the maximum power point of PV array.
WARNING: When the power of PV is not greater than the rated charging power, but the
maximum open-circuit voltage of PV array is more than 60(Tracer**06AN)/100V(Tracer**10AN)
(at the lowest environmental temperature), the controller may be damaged.
Condition 3:
Actual charging power of PV array
＞
Rated charging power of controller
Condition 4:
Actual charging current of PV array＞Rated charging current of controller
When the controller operates under “Condition 3”or“Condition 4”，it will carry out the charging as per the
rated current or power.
