Connecting 48V 300Ah Battery Bank to 150HP 460V 3-Phase Motor Drawing 170A Full Load

How do I go from a 48v 300ah battery bank to a 150HP 460v 3 phase eletric motor drawing 170amps at full load?

Thank You

Well first of all, I would not recommend running that kind of motor on battery such as stated. You need to convert your DC power to AC and three phase source. Its lot of complex process and not wise man decision to follow this path unless you have scientific research motive to invent something new. There is a separate mechanism called VFD (variable frequency drive) which is the only solution to safely start and run the motor pumps using the battery or solar.

However, theoretically, a 150hp needs a minimum of 111900W of power. A bank of 48v batteries need to handle 4662.5A. To run the motor for 4hrs means the bank should have a capacity of close to 18700Ah. This means a bank containing of 63 batteries of 300Ah.

All this not yet considering other requirements of the motor.

Thank you for your response. I understand that 1 hp is = to 745.7w, but what am I missing when the motor specs says that the motor running at full load draws 170 amps?

also if the system went battery bank to inverter to transformer ect ect to motor so that the finished voltage was 460/480 and the amps being used was 244~ to get the 111900w for 150hp, is the battery bank still needing to provide 4662.5amps?

All you have to consider is power out=power in plus an allowance for losses.
This sets the power for the battery, you have a defined voltage, which sets the current.
As Kevin said, how you get there is an altogether difficult issue. The first is how long do you want the system to run off batteries only, I assume you are talking about short term battery backup. That sets the ampere hour capacity needed.
Back up in this case would be better done with an engine powered 3 phase alternator.
You are talking about a high capacity DC to AC converter, the currents are very high, so losses will be comparatively high as well, you are talking big copper busses everywhere to keep losses down.
An indication of what you are trying to achieve would be useful.
