I had an interesting "problem" or limitation of one of my inverters that hopefully someone can explain. On my boat I have a 1000 watt true sign wave inverter and a 1400 watt modified sign wave inverter. I would prefer to use the TSW inverter all the time but my polishing pump is driven by a continuous duty, 1/3 hp AC motor and I often polish fuel while underway when the tanks are stirred up. I have good reasons for that setup as opposed to a DC pump/motor for fuel polishing but that's another story so I won't get into it here. The problem is the TSW inverter cannot handle the startup power spike of this motor and always trips out. For those who don't know, 1/3 hp is about 250 watts so the operational loads of this motor is well within the limits of the inverter but as I said, it just can't handle the startup spike. The interesting thing is that last year I forked out a lot of money to buy a 2000 watt TSW inverter thinking that would definitely have the beef to do the job but that one would trip out as well at startup so I returned it. However, the 1400 watt MSW inverter can start this motor with no problem. Does anybody know why this is?
