Dear Juan,
Thank you for your inquiry.
1. DC Power & Clipping Logic
We agree that the nominal DC output should be 100 kW. We will contact the manufacturer and request a correction.
The power is clipped when the nominal DC power is exceeded.
A warning message is issued when the maximum DC power is exceeded.
2. Defining Max. Power per MPP Tracker
The Max. Input Power per MPP Tracker is not found in the datasheet. Some manufacturers divide the total power by the number of MPP trackers, but this leads to error messages if the power is not evenly distributed across the trackers. Therefore, it's plausible that Growatt enters 18.75 kW here (instead of 10 kW or 15 kW). But we don't know exactly how the manufacturer calculates this value.
3. Global DC Data vs. Tracker Data
The maximum input current of the inverter is the product of the maximum input current of the MPP tracker and the number of MPP trackers, as in this example: 32 A * 10 = 320 A. However, some manufacturers enter something different.
We have noticed that the short-circuit current is incorrectly entered. According to the datasheet, the short-circuit current per MPP tracker is 40 A, so the short-circuit current of the inverter would be 400 A. We will contact the manufacturer and request a correction of both fields.
4. Physical Inputs vs. Trackers
We confirm that for an inverter with 10 trackers but 20 physical inputs (strings) the number of DC inputs is 20.
There are inverters with an odd number of DC inputs, e.g., 5 DC inputs with 3 MPP trackers. However, this is not the case with this Growatt inverter.
Suggestions for the development team
We have forwarded your suggestions to better align the electrical parameter designations with those found in most datasheets to our development team.
