CDP

Application notes

4.2.- REGULATION TEST

The following test can be performed to ensure the

CDP

is correctly performing

the regulation:

We assume a 3000W inverter generating 1400W.

Now we program the

CDP

indicating that the inverter power is 6000W. The

CDP

will send the inverter a new setpoint so it can change its MPPT and the inverter
will reduce photovoltaic generation by 50%, generating 700W.

Do not forget to reprogram the

CDP

with the initial inverter power value

after completing the test.
