Ratings & Reviews
- This app has not received enough ratings or reviews to display an overview.
Inverter current check now follows the printed NEC 690.8(A)(1) rule:
- Imax = array Isc x 1.25 compared against inverter max DC input (was x1.5625 - the extra 125% continuous factor belongs to conductors/OCPD, not equipment ratings; normal arrays no longer flag as incompatible)
- Result cites the rule and reminds to verify the inverter max short-circuit input rating
