1 - The maximum input voltage is the upper limit of the DC voltage. Any higher input DC voltage would probably damage inverter. 2 - Any DC input voltage beyond the operating voltage range may result in inverter improper operating. 3 - For Austria, German, Belgium & Ukraine the Max. AC Apparent Power will not exceed 30,000 VA (with regard to grid code: VDE-AR-N-4105, C10/11 & Austria) 4 - SUN2000-30~40KTL-M3 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), N-type (nPERT, HIT)
