Most of the current battery based inverters can handle a swing from 40 volts to 65 volts (for a 48 volt nominal nife bank) though output voltage regulation may not always be in spec at the far ends. A lead acid bank might swing between 46 and 60volts for comparison. Older inverters did not always have as wide of a range.
The aquair batteries that everyone has bee hearing about recently apparently have an even wider swing--something like 36 to 70 volts, and inverter manufactures are working on new inverters that can maintain output spec with that input swing from what I hear. I've been pretty happy with nife and flooded nicad. Yes, they are not quite as efficient but in some cases lead acid was lasting only 4 years (heavy wintertime sulphation) and nicad is currently on 22 years.
