[RE-wrenches] MS4448AE compatibility question

[greg at remotepowerinc.com]

Allan,

We've had problems with running some toyo and monitor heaters on some  
inverters.  A friend of mine has successfully used APC computer UPS  
unit's - the sine wave versions, to solve the problem.  I haven't  
tried this myself yet but this guy's a really sharp tech and I have no  
reason not to believe he's right again.  I believe you can get one for  
under $300 so if you have just one piece of equipment that's not  
liking the Magnum's waveform it would be a relatively inexpensive fix.

Best,

Greg
