FFICIENCY AND POWER LIMITATION
The inverter limits its output power in the following situations:
PV generator power exceeds maximum inverter power
MPP current on the PV generator is higher than the "Max. input current". See "Figure 1" in the Appendix.
The gird voltage is less than the "Minimum voltage at rated power". In this case, the inverter limits output current to
"Max. output current".
Inverter temperature exceeds the "Rated power temperature range": in this case, the inverter reduces the output power.
In the cases provided for by local regulations: see the „INFORMATION‟ menu paragraph.
In all the aforementioned cases, the yellow LED lights up on the inverter.

Incompatible firmware loaded on microprocessors
The inverter auxiliary power not working properly
Inverter differential sensor fault
Relay fault
Attempts to reconnect run out because of a ground
leakage.
The DSP have performed an operating error.
The inverter has received a remote shutdown
command. It remains in this state until receiving an
unlock command (remote or manual)
Analogue readings reference fault
Grid voltage reading does not match between the
two microprocessors
Grid frequency reading does not match between the
two microprocessors
Leakage current reading does not match between
the two microprocessors
