Title: Inverter
Post by: David Fischer on March 21, 2013, 02:17:04 AM

It is looking like I may be having inverter problems and may have to replace my old Freedom2000.  Before going any further into the problem, it seems to me that there was a discussion once about modified sine wave and full sine wave inverters, especially when using with a household type refrigerator.  Can anyone guide me in the right direction as to where I can get information on this.  I am thinking of putting in a household type refer if I have to go ahead and get a new inverter.  
My coach is a 97 Marquis and hold 6 batteries plus 3 engine batteries.
Thanks
David

David-

Try reading the following thread about glass mat batteries.  It includes a discussion about true sine wave/modified sine wave and residential fridges.

Personally, if I had to put out dough to replace my inverter anyway, I'd go the extra bucks for a true sine wave Magnum, even if some residential fridges like Samsungs apparently work okay on modified.  The fridge isn't the only device you plug in, and true sine wave 60 cycle is the same AC form as regular household current.   The following link, courtesy of member Steve Huber, is pretty explanatory:

And this retailer also gives good reasons for having a true or pure sine wave inverter:  http://www.donrowe.com/inverters/inverter_faq.html#modified
