I bought a Vanner Inverter / Charger off eBay... ITC Series. It's used, but supposedly works, and has a refund guarantee. The packing was horrible - a 75lb inverter in a Frito-Lay box. The inverter survived ok, but the remote panel got damaged to the point of not functioning. With much anxiety, I connected it to my house batteries through a 40 amp fuse (just to be conservative). There was the usual spark when the fuse was first installed. I connected various loads ranging from 20 watts up to about 900 watts (a hairdryer). Here's where I'm confused. I connected a multimeter to it and got a consistent 119-120.5 volts - that part is good. I switched my meter to Hz and the numbers jumped all around so quickly I couldn't even say them. Is this indicative of a modified sine wave inverter? The hair dryer 'sounded' fine (the same pitch as always). I also plugged in a fan and it seemed to run correctly, too. I can find no information on this inverter. I've emailed Vanner, but I got an out of office reply. I'm looking for any information or experiences on this inverter. I've attached a picture of the information label on the inverter. Thanks for any help. David  | ||

Hi David: There is a whole bunch of info on a model SP00112, on Google, Could be an early model, hopefully having some of the same characteristics as your SP00172. Yes! it is MOST difficult to determine the wave shape without an oscilloscope AyJay | ||

AyJay, Actually, it is a current model and was manufactured last January ('06). The service manager I talked to said it is a true sine wave model and should read 60 Hz on my meter. He also said it's under warranty, so I'm going to verify this before keeping it (I have a 15 day warranty from the seller). If I do end up keeping it, it should be a nice inverter for a great price. Thanks for the reply. David |
