[RE-wrenches] "DC current Injection": Whazzat?

2017-08-17 Thread Mick Abraham
Hi, Wrenchies~ My client has an AC coupled battery based setup. The batteries are good ol' lead floodies in pretty good health, the battery based inverter is Magnum MS4448PAE, & the string inverter is SolarEdge. There's also a Magnum ACLD "AC Load Diversion" control to regulate battery state of ch

Maybe the blender in question uses some kind of half wave rectification to control speed or something like that ? boB On 8/17/2017 8:43 AM, RE Ellison wrote: If getting rid of the blender which is the easier choice or at least trying a different blender to see if that does it is out of the

Help Mick, With the Magnum AC coupled to the SE inverter, I suggest it’s an issue with Magnum power quality (reactance) with the blender controls/motor and the resulting AC waveform that is feeding the SE inverter. I have seen this before with Magnum Energy. Can you look at the waveform or PQ w
