I've been reading up on the OzTules inverter threads, neat stuff! I'm considering my options for a cheapish inverter for my Bus RV conversion, and see this giant on eBay and other places... I get the idea the transformers might be undersized, but can this thing even come CLOSE to meeting it's specs? That's ~1200amps on the DC side!
Why do I want to run 12v? Well I managed to get my hands on six 6v 370ahr slightly used batteries for a song, 36v gear is nonexistant, if I run 24v I can only use 4 of them, if I run 48v I'd have to add two more for more than I paid for the other six, and suffer charge imbalance issues, but if I run 12v I can use them all and that works well with everything else in the vehicle.
My general load requirements will probably be under 1500w peak for most of the year, but I take the vehicle to events where I'll be powering tons of other gear including multiple air conditioners intermittantly too. I have a 2 cylinder kubota diesel onboard that currently is belt feeding a 4kW AC head, but that head is slowly failing. I found a 24v 400A readily affordble surplus generator that I'm pretty sure I can mod the regulator on to get it outputting 12v at a current set by a potentiometer, freeing me to run the engine at variable RPM with the load requirements at 14v 400+A matching the torque curve of my engine perfectly. Being able to run the rpm lower or shut it off entirely to save fuel at light loads is appealing as well, and I'll likely throw some solar on the roof at some point too.
So I guess my question is, what actual performance could I expect from the "powerjack" 12v 15kW inverter as is?
