 PV array maximum power
This MPPT controller has a limiting function of charging current, the charging
current will be limited within rated range, therefore, the controller will charge the
battery with the rated charging power even if the input power at the PV exceeds.
The actual operation power of the PV array conforms to the conditions below:
1） PV array actual power ≤ controller rated charge power, the controller charge
battery at actual maximum power point.
2） PV array actual power > controller rated charge power, the controller charge
battery at rated power.
If the PV array higher than rated power, the charging time at rated power to battery
will be longer, more energy to battery yields.
WARNING: Controller will be damaged when the PV array straight
polarity and the actual operation power of the PV array is three times
greater than the rated charge power!
WARNING: Controller will be damaged when the PV array reverse
polarity and the actual operation power of the PV array is 1.5 times
greater than the rated charge power!
When the PV array straight polarity, the actual operation of the PV array must NOT
exceed three times of rated charge power, When the PV array reverse polarity, the
actual operation must NOT exceed 1.5 times. For real application please refer to
the table below:
