I tried to run a couple of Taco 005 circulator pumps from a 12 VDC battery
and an inverter and couldn't do it - the pumps hummed or buzzed or
something but never seemed to run as smoothly as they do when plugged into
the house's AC system. The pumps are 1/25th HP with a .5 amp rating and I
would have thought that they'd run fine on the inverter. I tried two
different invertors, both of which work fine otherwise and also tried
running one pump at a time. The invertors are rated at 400 and 700 watts.
What's going wrong and how can I fix it? The objective is to be able to run
the pumps from lead-acid batteries.
