Why does the V Sense connection on my MultiPlus-II 2x 120 V inverter charger power my inverter charger and other items connected to my Lynx Distributor?
I Just installed my MultiPlus-II 2x 120V. I’ve attached the AC lines (in and out 1), but not connected to shore power. The chassis ground of the MultiPlus is attached to the chassis ground through the negative busbar of the Lynx Distributor. The negative busbar of the Lynx Distributor is also connected to my battery bank via a SmartShunt. The positive busbar of the Lynx Distributor is isolated from the batteries by an uninstalled class T fuse and the battery disconnect switch being in the off position. The positive and negative DC connections of the MultiPlus are connected to the positive and negative busbars of the Lynx Distributor.
When I attached a pair of wires directly from the batteries to the V Sense input of the MultiPlus-II the MultiPlus-II, which was inadvertently on, began to operate and energized the Lynx busbars. The busbars remained energized even after the MultiPlus was turned off. This results in battery draw even with the disconnect switch in the off position. Any ideas or insights would be welcome.
