Solartec Central 100 uses a low frequency transformer. It securely connects the inverter to the grid. The wide range of DC input raises the g enerating efficiency and return, and facilitates the combination of PV modules. The highest working altitude is 6000m (If above 3000m, it sho uld be derated before use.) and is suitable for use in various geographical environments. Efficientþ Efficiency of up to 98.3 % Flexibleþ Reactive power supplyþ Extended temperature range from -25øC ~ +55øCþ Compact dimensions, easier installation Reliableþ Active and passive islanding detectionþ Powerful grid management functionþ Low-voltage ride through function Communicativeþ Optical fiber remote monitoring
