M-Vision è il sistema di supervisione che monitora accuratamente il funzionamento di ogni componente del tuo impianto fotovoltaico. Rielaborando tutte le informazioni acquisite dai sensori ambientali e acquisendo tutti i parametri elettrici dei componenti installati (contatori, inverter, interruttori, ups, solarimetri ecc... ), ti consente di valutarne in tempo reale l’effettivo livello di performance, fino a conoscere la power ratio di ogni singolo inverter di stringa. Grazie all’interfaccia, puoi controllare in modo immediato il tuo impianto da un qualsiasi dispositivo che disponga di una connessione ad internet: la segretezza e la privacy durante la consultazione vengono garantite dall’utilizzo del protocollo di sicurezza SSL. I numerosi menù messi a disposizione rendono M-Vision uno strumento adatto alla consultazione sia da parte di un’utenza tecnica che di un’utenza gestionale. Qualora volessi monitorare più impianti, troverai nella prima pagina una schermata di riepilogo che riporta lo stato e la performance di ognuno.
