January 25, 20251 yr Hi all, I am struggling to figure out what I am doing wrong or if my inverter is just broken. I have a Sna5000 luxpower inverter and it has 2 x dry contact relays at the bottom, 1 for the generator and 1 for low battery warning and battery float voltage reached. I have gone through all the settings on the inverter and on the web settings there is no place to active the dry contacts but when I take my multimeter I am not getting any continuity between any com, NC or NO. Is anyone here using these contacts and how did you get it to work? I have a sunsynk at my shop and is spoiled by it's CT's that gives it the ability to export excess solar power to non essential loads without exporting to the grid. So basically what I want to do with the dry contacts is to add the non essential loads via a smart changeover to the inverter load up until the gen relay clicks so that the non essential loads does not deplete my battery.

The easiest way to check if the contacts are present and working is to switch the inverter off. Then no matter what condition is present you should have continuity between COM1 and NC1. Also between COM2 and NC2. When this is in place COM1 and NO1 should close with the inverter on and the battery below the warning voltage while you have the grid switched OFF. The same on COM2 and NO2. Reply after you have tested.
