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
50(Tracer**06AN)/96V(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.
WARNING: When the power of PV module is greater than the rated
charging power, and the maximum open-circuit voltage of PV array is more
than 50(Tracer**06AN)/96V(Tracer**10AN)(at the lowest environmental
temperature), the controller may be damaged.
According to “Peak Sun Hours diagram”, if the power of PV array exceeds the rated
charging power of controller, then the charging time as per the rated power will be
prolonged, so that more energy can be obtained for charging the battery. However, in
the practical application, the maximum power of PV array shall be not greater than 1.5
x the rated charging power of controller. If the maximum power of PV array exceeds
the rated charging power of controller too much, it will not only cause the waste of PV
modules, but also increase the open-circuit voltage of PV array due to the influence of
environmental temperature, which may make the probability of damage to the
controller rise. Therefore, it is very important to configure the system reasonably. For
the recommended maximum power of PV array for this controller, please refer to the
table below:
