We put the KG140F through it's paces in this review:
On the whole I quite like the KG140F. I had both Victron and KG140F installed and over a week of touring I used them both quite extensively.
Because we use quite a bit of power I like to know the real SOC at any one time.
In this review I looked mainly at the KG140F, comparing it side-by-side with the Victron Smartshunt and also checked what my Daly 200A Smart BMS was telling me.
I quite liked the HUD, I sometimes used the app on my iPhone but TBH most of the time I just want to glance over and check the display.
But to make it really useful the KG140F could do with this important improvement to the heads-up-display (to the content on the HUD):
1. The Volts and Current Amps are the biggest and boldest. This is a waste of real estate.
2. I want these two items to use the most real estate and to be big and bold so I can glance over from where I'm sitting:
a) AH consumed
b) SOC
3. The HUD shows AH remaining, that's OK-ish but I prefer Ah consumed
4. Why not show both AH remaining and AH consumed, in fact I'd like the HUD to show these 4 figures nice and bold:
a) AH Consumed
b) AH Remaining
c) SOC
d) Current Amps being drawn
5. Remove the bling (those fancy dials don't do anything for me)
6. Don't waste space with really irrelevant stuff like internal resistance (put that on an "other" tab)
In terms of installing the unit:
1. Why not make the HUD wireless so it can easily be mounted anywhere?
2. If they can't make the HUD wireless, provide a longer cable than the puny 3m one supplied
3. Put the plug socket on the HUD on the side, not the back
4. The shunt itself had some after-thought mounts added which have a lot to be desired (Victron is miles better)
