Prezentare Invertoare STECA seria 300/500 & 2000+

Seria MiniString este compusa din invertoarele StecaGrid 300 si StecaGrid 500, cu o putere nominala de 300W si 500W, construite intr-o maniera modulara si simpla pentru a fi instalat. Avand posibilitatea distributiei pe cele trei faze sistemul poate fi extins la dorinta utilizatorului. Sistemul dispune de tehnologia MPPT si are o eficienta de pana la 95,8%.StecaGrid Control monitorizeaza un sistem cu o iesire maxima de 3600W. In Germania, Austria si Franta de exemplu, datorita standardelor aplicate, utilizarea modului StecaGrid Control D1 avand integrata functia de grid-monitoring (monitorizare retea) MSD si intrerupatorul de retea pentru curent rezidual, este obligatorie. In alte tari ca Olanda, este utilizat numai modulul StecaGrid Control N.
Afisajul StecaGrid Control ofera atat informatia referitoare la energia produsa cat si starea sistemului.Multumita sistemului modular, acest invertor permite injectia in retea incepand cu valori foarte mici, ocupand un spatiu fizic foarte mic. Aceste invertoare au fost fabricate pentru a utiliza energia solara intru-un mod cat mai simplu.
Invertoarele Steca din seria 2000+ au fost dezvoltate pentru a acoperii puteri de pana la 10KW.
