[RE-wrenches] DR>FX Compatibility Problem, Magnum inverters

[Larry Crutcher, Starlight Solar]

Yes. I thought of that so we turned on a few hundred watts. Same  
problem. The Splindide power board is causing the issue. I tried RF  
filtering, twisting inverter leads, EMI AC filter. Nothing would work.  
It's really weird that a cheap import inverter would operate it.
