Offgridtec MPPT Pro Duo Bedienungsanleitung Seite 30

Condition3,
Actual charging power of PV array ＞ Rated charging power of the controller
Condition4,
Actual charging power of PV array ＞ Rate charging current of controller
When the controller operates under "Condition 3" or "Condition 4", it will carry out the charging as per the actual current or
power.
WARNING: When the power of PV is higher than the rated charging power, but the maximum open-circuit voltage of
PV array is more than 60V(**60)/100V(**100)(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 the PV array shall be not higher than 1.5 times the rated
charging power of the 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.
