On both the Cerbo GX:
... and on the VRM:
... the amps and watts wildly disagree. I know that our usage on the boat right now is super low -- the watts look about right -- but it's showing several amps of usage. The math is pretty simple -- W=A*V. What gives? I've never bothered to pull out the access covers and use a clamp ammeter to validate, but I'd be pretty shocked if I was actually pulling 6 amps combined -- I have no idea where that 700 watts would be going, and when we're off shore power, all the watt numbers add up to correct battery usage. So it feels like this is just a calculation error by the Cerbo/Quattros, but it's pretty eggregious.
