Sewer Pump 1/2HP 120vac / DR2424 [RE-wrenches]

[ezra at lasqueti.net]

I don't have personal experience with this particular application, but I do have experience running
1/3 hp pressure pump with Trace U series inverters (2624 and 2012).  Both of these inverters would
start the pump with no pressure in the tank just fine, as soon as there was pressure the inverter
would bog down.  I installed a capacitor on the start winding and all worked fine.  Given the pump
is likely pumping against no pressure it should likely start-running would not be an issue if you
can get started.  If the pump won't start, you might consider the capacitor trick as well.
