Safe

Safe handling at all times

Dur­ing instal­la­tion of our micro-invert­ers, all AC cabling is com­plete­ly volt­age free. As long as there is no con­nec­tion to the main grid, the invert­ers are switched off. The trans­former-based topol­o­gy in the invert­ers leads to a fail-safe gal­van­ic iso­la­tion and also, the DC volt­age is lim­it­ed to the com­plete­ly safe volt­age of one PV mod­ule, i.e., ~ 40 V. Han­dling of cables is total­ly care­free and does not require any spe­cial safe­ty precautions.

Nev­er any han­dling of 1,000 V DC voltages!

Self limiting and Safe by Design

Our micro-invert­ers are self-lim­it­ing and there­by inher­ent­ly safe. Each invert­er mea­sures the string cur­rent and if it is too high, i.e., above the max­i­mum string cur­rent of 20 A, it will sim­ply reduce its pow­er accord­ing­ly. Even when adding too many mod­ules to a string, there is nev­er any safe­ty risk or risk of dam­ag­ing the inverters.

Compliant with rapid-shutdown regulation

As soon as the grid is off, the invert­ers auto­mat­i­cal­ly switch off. The trans­former-based topol­o­gy in the invert­ers leads to a fail-safe gal­van­ic iso­la­tion and also, the DC volt­age is lim­it­ed to the com­plete­ly safe volt­age of one PV mod­ule, i.e., ~ 40 V. NS-pro­tec­tion is includ­ed in every inverter.
