Determining Total Daily Output

Is there a good way to determine the total daily output of your panels? I don't see anywhere in the MPPTracker software that says "X total watts produced today". I'd like to know exactly how many watts (watt hours, whatever the correct term is) per day are being produced. I can get a rough idea by looking at the inverter output and victron amount going to the batteries, but this is inaccurate and does not take in to account losses at each step.

Thoughts? Any devices I can add on between the charge controller and inverter? I guess another victron would do the trick, but perhaps there's a cumulative watt meter like the kill-a-watt for DC I can use instead?

Thanks!

You want something that preferable sits between the pv panels and the mppt charge controller right?

You could use a victron 702 between solar panels and the charge controller if your voltage is in that range. Or otherwise an arduino and a shunt there would do the trick as well.


Im sorry if i perhaps didnt understand what you wanted

KWh is the correct measurement term - there's plenty of cumulative meters around, just pick one to suit your pocket and voltage

But I'd be very surprised if that's not recorded by your software.
