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 charge when there's no grid power.
When there's no grid power & the system is on it's own, the SE inverter sometimes throws an error code 36 "DC current injection". This happens when the mongo blender is operated (Vitamix brand, older model) & again in a >no public power grid< situation. The error causes the synchronizing string inverter to de-couple from the Magnum then the standard five minute time-out ensues before a re-couple. I think DC current injection is when the transformer-less SE inverter pumps a blip of DC into the grid--or micro-grid when there's no grid power--and I guess DC injection is IEEE verboten because it compromises power quality/power purity. Can the experts confirm if this is correct understanding, explain how DC can show up on the AC, and offer suggestions other than a replacement blender? Thanks as always. The Wrench List is the Bomb!
