COSA FARE DOPO LA ROTTAMAZIONE
Non smaltire l’inverter insieme ai rifiuti domestici. L’utente ha la responsabilità
e l’obbligo di inviarlo all’organizzazione designata per il riciclaggio e lo smaltimento.
CONSEGNA ED INSTALLAZIONE
Mantenere l’imballaggio e il dispositivo completi, asciutti e puliti durante lo
stoccaggio e la spedizione.
Si prega di smontare ed installare l’inverter con due o più persone, poiché
l’inverter è pesante.
Smontare ed installare l’inverter con strumenti adeguati a garantire un
funzionamento sicuro e normale ed evitare lesioni fisiche o morte. Le persone devono inoltre adottare misure di protezione meccanica, come calzature protettive ed abbigliamento da lavoro.
L’inverter può essere installato soltanto da elettricisti qualificati. Non collocare ed installare l’inverter sopra o vicino a materiali combustibili. Il luogo di installazione deve essere lontano da bambini ed altri luoghi pubblici. Prima dell’installazione e della connessione alla rete elettrica, rimuovere i
gioielli di metallo, come anelli e bracciali, per evitare scosse elettriche.
Prima della connessione alla rete elettrica, coprire i moduli solari con materiali
resistenti alla luce. Se esposti alla luce solare, i moduli solari emettono una tensione pericolosa.
La tensione di ingresso dell’inverter non deve superare la tensione massima
di ingresso; in caso contrario, l’inverter potrebbe danneggiarsi.
I poli positivo e negativo dei moduli solari non devono essere collegati a
terra, altrimenti si possono verificare danni irrecuperabili.

SISTEMA DI GENERAZIONE DI ENERGIA SOLARE CONNESSO ALLA RETE APPLICAZIONE Il sistema di generazione di energia fotovoltaica connesso alla rete è costituito da moduli solari, un inverter connesso alla rete, dispositivi di misurazione e una rete pubblica.
Figura 1 Applicazione delle serie di inverter solari connessi alla rete L’inverter solare connesso alla rete è alla base del sistema di generazione di energia fotovoltaica. L’energia solare può essere convertita in energia elettrica sotto forma di corrente continua attraverso i moduli solari e quindi trasformata in energia elettrica sotto forma di corrente alternata sinusoidale con la stessa frequenza e fase della rete pubblica dagli inverter solari connessi alla rete, per poi essere immessa nella rete. Le serie di inverter solari connessi alla rete vengono applicati soltanto ai sistemi di generazione di energia solare connessi alla rete ed il loro ingresso della corrente continua è costituito soltanto da moduli solari in silicio cristallino i cui poli negativi e positivi non sono collegati a terra.

I moduli solari consigliati devono essere conformi allo standard IEC61730 Classe A.
LINEE GUIDA PER LA SICUREZZA
Le serie di inverter solari connessi alla rete supportano le connessioni alla rete TN-S, TN-C, TN-C-S e TT. Quando si applica alla connessione TT, la tensione zero-terra (N-PE) deve essere inferiore a 30 V.
