1 - Inverter max input PV power is 40,000 Wp when long strings are designed and fully connected with SUN2000-450W-P power optimizers. 2 - The maximum input voltage is the upper limit of the DC voltage. Any higher input DC voltage would probably damage inverter. 3 - Any DC input voltage beyond the operating voltage range may result in inverter improper operating. 4 - SUN2000-12~20KTL-M2 raises potential between PV- and ground to above zero through integrated PID recovery function to recover module degradation from PID. Supported module types include: P-type (mono, poly) 5 -. <10 W when PID recovery function is activated.
