API field
Series diode voltage drop
Voltage lost across a blocking diode in each string
Unit V
What it is
The forward voltage drop of a blocking diode in series with each string, in volts. The loss counts in the DC wiring loss row. The drop also lowers the voltage the inverter sees.
Typical values and how to get it
0 for a system without blocking diodes, about 0.7 V per silicon diode otherwise.
How it is applied
