Not much use
It works but it is not much use because it hardly shows anything because the shunt is actually a 500A shunt when it is advertised as 300! Having read that you need to pick a shunt rated so that your usage range is at the 2/3 point of the shunt capacity. So with a max 200A usage I picked the VAT-1300 expecting a 300A shunt! Only found out once installed so have to keep it... Thus I can't comment on its accuracy, it shows 96A when using 1150W from inverter which is what I calculated but nothing at lower current draws. Also shows charging as negative rather the other way round as you would expect.
