48VDC to 240VAC daisy chain inverters
Generally not.

Inverters generate AC. If inverters were to be paralleled they would need to be synchronised so that the AC was of identical frequency and phase. This isn't likely to be possible with the class of unit I suspect you are thinking of. (Generator sets require the same synchronisation but can be pulled into synch electro-mechanically.)

Note: KW = kelvin-watts which doesn't make any sense. kW = kilo-watts. Small 'k' for 'kilo' as defined in SI units.
