[RE-wrenches] Wattage 1/2 HP vs 1HP septic pumps

[Dana]

Ok all you whiz kids, bozos, & bolos:

 

If I have a septic lift pump [off grid ouch] at 1HP/240 vac/8-amps to meet
all the usual state required overkill in septic design & a ½ HP/240
vac/4.9-amp pump would do the same job but it will take 10% more time to
dose 800 gallons.

Powered by an 8 KW Outback Radian inverter.

>From a load point of view and a 240-volt 3 phase wild AC well pump limiting
the overall surge and general wattage is the smartest move, but; Which pump
will use less overall power? We are using 240 volt to utilize both inverters
and drop the load on either half of the Radian inverter.

Is there a smarter lift pump to use? ECM motor? Permanent magnet?
