We have a site that was working perfectly fine then one day I woe up to this:
This site is off-grid and only has 1200w of solar capacity and definatly not capable of supporting nearly 1000A (shunt is a 500A model). Site actual power draw is actually around 100w and is so low the graph can't even show it due to the fault scaling the numbers so high:
We have swapped the BMV and shunt but still get the same readings. And I can confirm we have only connected cables to the shunt bolt terminals not the PCB screws.
Any idea why this would happen randomly is it the GX given a shunt/BMV swap didn't fix it and if so any idea where I can check settings/calibration?
