I supplied one of those to someone around 5 years ago. Apparently he never really ending up using it as he found the display was too bright. So was fitted out the way and not really visible. Quite a common complaint actually as the backlight stays on and when the batteries are charging it pulses on and off to tell you. It is a good monitor but that feature can be rather annoying.
I've switched to the
Victron units and as it happens fitted the
BMV-712 for him last week instead.
One other thing to watch for with the Alii monitor ... The cable from
shunt to display is ridiculously short and you may need to extend it (I DIY an extension. You can buy an extension lead but they are silly money for a bit of telephone-guage cable).
