This seems like a really simple set-up but apparently I need help! Xantrex ProWatt SW 2000 inverter (4000W surge) connected to a Ampere Time 200Ah 12V battery, with 8" 00 cables. Has no problem running a 1500W ~13A hairdryer, or 700W shop vac, or running both my fridge and freezer together. It wouldn't start my existing well pump that I didn't know much about (I don't remember the error it would show) so I just had it replaced with a soft start Grundfos 5SQ05-180, which manufacturer shows at 115V full load amps is 7.7. I did find another table that shows 12A max, so I'm not sure which. But when I plug it in and the water pressure falls to 35 so it tries to start, the push-button breaker on the output of the inverter trips right away. Even the old pump didn't trip the breaker.
The pump never trips the 20A house power breaker, and this breaker on the inverter must be at least 17A, so I don't get it!
