I have 2 Multi Compact 2Kva/24v in parallel with a BlueSolar 150/70 connected to a 605A SOPZ bank.The cables to the bush bar are 50mm2 and from bar to inverters 35mm2 , distances matching to almost mm.
Since I have not received yet the VE.Direct 2 USB cable (for the smartshunt) I just connected the MK2 onto the Rasberry.
What is strange is that I have a big discrepancy between AC loads and discharging, meaning 76% efficiency.
Since the discharge measurement is also coming from the Multi, it cant be a matter of cabling, not to mention the load is so small to be affected by the cabling.
Any ideas??
It says 2 batts, but it means 2 readings from 1 batt. The dcA usually matches but the Multi is always 30-40 W lower than the shunt. Can't happen with dc, so the figures are fudged somehow to make presentable. But the W on the Multi closely matches the AC Loads W. The acA ends up wherever with a less than unity poiwer factor at play somewhere. I reckon I lose 30-40 W continuously, day and night. But it doesn't interrupt my sleep, hey. :)
