● Standard Features ○ Advanced —Not available.

1) Below rated voltage AC power is reduced in the same proportion.
2) Efficiency measured without internal power supply.
3) Full AC power at higher DC voltages on request.
4) Own consumption at nominal operation
5) Self-consumption at < 75% Pn at 25°C
6) Self-consumption averages from 5% to 100% Pn at 25°C.
7) Sound pressure level at a distance of 10 m.
8) Values ​​only apply to inverters. The permissible values ​​for SMA MV solutions from SMA can be found in the corresponding data sheets.
9) Short circuit ratio < 2 requires special SMA approval.
10) Max. Power values ​​(S/P/Q) may be requested depending on the specific project.
11) Earlier temperature derating and DC open circuit voltage reduction.
