Battery systems for 440v industrial motors
The common solution is not to use battery power inverters but AC to DC to AC inverter "variable frequency drives" or VFD's. 

These start from DC and accelerate line frequency ( or less to the desired RPM ) by raising sinusoidal 3 phase  V with f to keep V/f constant and thus increase current with RPM to prevent high acceleration currents that occur from full voltage to start an induction motor. 

These can give constant torque with acceleration constant rise to target speed. (RPM) or slightly higher than constant torque with faster acceleration such that peak/load power can be kept as close to unity as required. 

This also reduces mechanical step power resonances to pumps and other mechanical systems by reducing the slew rate of speed and thereby reducing the bandwidth of mechanical spectrum of shock defined by the rate of acceleration to a mechanical load which may have some natural frequency of vibration.
