Can anyone please explain why im able to consume more power than what the batteries and solar generation are giving me? See pic
So you have 560W ac out being measured and the Multiplus says it is taking in 591W due to idle current / conversion losses and you are supplying 127 + 394 = 527W (Lynx plus Solar).
The Lynx Shunt at 2.4A is right at the bottom of its range (0.24%) so a small error in terms of Amp value has a significant % age impact. An accuracy figure is not stated on the Lynx Shunt datasheet, for the SmartShunts it is 0.4%, accuracy is normally quoted in terms of full range so accuracy would be 4A.
Check when you do not have solar running at night and then cross check the Lynx Shunt against the inverter.
