Engineer reviewCold Voc1,060 VHot Vmpp698 VMPPT current15.0 AArray STC10,450 W
WarningMaximum DC input voltage
1,060.3 ≤ 1100 V
Cause and next action
Cold module voltage is the highest expected string open-circuit voltage.
Next: Reduce modules per string or select an inverter with a higher DC input rating.
PassModule maximum system voltage
1,060.3 ≤ 1500 V
Cause and next action
The cold string voltage must remain below the module system-voltage rating.
Next: Reduce modules per string or use a module rated for the required system voltage.
PassMPPT upper operating bound
882.5 ≤ 1000 V
Cause and next action
Cold operating voltage may approach the top of the inverter MPPT window.
Next: Reduce modules per string or select a wider MPPT window.
PassMPPT lower operating bound
698.3 ≥ 200 V
Cause and next action
Hot module voltage is the lowest expected operating string voltage.
Next: Increase modules per string or select an inverter with a lower MPPT start range.
PassCold MPPT operating window
882.5 200–1000 V
Cause and next action
The cold operating point must remain inside the tracked voltage range.
Next: Adjust the string length before approving the configuration.
PassPer-MPPT input current
15.0 ≤ 26.0 A
Cause and next action
Parallel-string short-circuit current is used as the conservative input-current basis.
Next: Reduce parallel strings per MPPT or choose an inverter with greater current headroom.
PassInverter short-circuit current
15.0 ≤ 36.0 A
Cause and next action
The inverter short-circuit input rating must not be exceeded.
Next: Reduce parallel strings or select a compatible input configuration.
Engineer reviewDC / AC ratio
0.10 1.00–1.30 preferred
Cause and next action
The ratio is a project yield and clipping decision rather than a stand-alone safety limit.
Next: Confirm clipping, irradiance and inverter-loading assumptions with the project engineer.
PassStrings per MPPT / external combiner
1.0 ≤ 2 direct strings
Cause and next action
The selected parallel count exceeds the stated direct-input arrangement.
Next: Define an external combiner, individual string protection and the approved wiring arrangement.
PassMaximum PV input power
10,450.0 ≤ 120000 W
Cause and next action
The complete PV array STC power must remain within the inverter PV input limit.
Next: Reduce the array connected to this inverter or select a higher PV-input rating.
PassString fuse / reverse-current review
0.0 Single string
Cause and next action
No parallel-string reverse-current condition exists.
Next: No additional parallel-string fuse decision is required by this check.
This tool is a configuration review input. Final ratings, protection coordination and site design require project-specific engineering confirmation.
