Schneider Conext ComBox log file retrieval

mike95490

Wondering if any Combox users have figured an easy way to extract the daily logs, other than going through the menus and downloading
one
file
at
a
boring
time ?

Any trick to use a flash drive once a month or some way to copy the uSD card contents easily ?

Is there a log that records daily load kwh usage? I know it shows it on the current days load screen,but where the heck is it logged?
I get lost easily digging through everything that the combox records.

It logs it in a short term 7 day rolling history.   But you can set the custom logging to record it for all time, on the uSD card you supply.

Thanks,I have the custom logging set up,just not finding where to set up for daily kwh's. I will do some more digging.

Which charger?  The xw-80-600v logs back to 2010 when I got the first one. An early adapter from a beta program.

The xw60, but that shows the harvest,what I'm looking for is load  kwh usage daily from the inverter.
It shows it on the loads screen,daily,weekly and yearly totals,but can't find where to set it up so it shows that on custom logging.

here's a couple screen shots of where/how to set up the logging for the combox .  Note the resolution of the data depends on how often you record data.

Thanks Mike,but correct me if I'm wrong here. The load watts (that you have highlighted) it is what the load is at that point in time, not  a cumulative amount.
Only place I can see anything in kwh's is on the loads screen in system  performance.
Guess I could always use a pencil and paper and write it down!

In the home screen, click n the LOAD icon, and you can view Hourly, daily & monthly history.,  (you my have to scroll down to get the the hour/day/month drop down box)  I don't know about lifetime history, i've not looked for it, 
They Gateway shows it, I don't know it it totals it, or just reflects the inverters status.

found, on the LOADS, the round box almost dead center, LIFETIME power.   Is this what you a looking for  ?
Scroll down to get the dropdown menu for the week, month, year graphing.  My lifetime is 1125.2 KWh

Yes I have seen all this,what I am looking for is this kwh info that shows up  on that load screen to be logged in custom logging.
Don't think it can be done.
What started this was I changed my generator head on my diesel. I went to an alternator to charge the batteries directly,so no problems with the generator sync up with the inverter and drop out under a surge load. And no trying to get gen support set just right.
But the problem is the gen output doesn't show up on the combox now,so hard to keep track of total gen output.
Daily kwh logging minus solar harvest kwh might give me a idea of gen input,so would be nice if it could be logged along with everything else in custom logging.

If I can get a 1930's Lister with 5.5hz power stroke "flicker" dialed in with Gen Support (I have about 5hz governor drift from full load to no load) I can't imagine anyone having issues with proper software setup for the AC2 and Gen Support settings, if the engine is running right,  I also have a Robin/Subaru/Hatz genset that, at the 50hr mark, the governor failed and had to be repaired at my expense.
For a 3Kw lister and a 800ah battery bank I use the following (Schneider derates breaker settings 20%)

Battery Bank Capacity 1000 A (1,000A makes for easy, direct conversion to charging amps,
  mistakes are limited by the AC2 & Generator Support amps limits)

Maximum Charge Rate 5-35 A

AC2 Breaker Size 19.5 A (each breaker is only @ 120V so both will add, this setting = a limit of 4680w, derated to 3744w)
 (This allows a brief surge for motor starting)

Generator Support Enable Enabled

Generator Support amps 13.1 A (each breaker is only @ 120V so both will add, this setting = a limit derated to 2515w)
 (after 2500w, charging is reduced to shift power to loads, if it increased beyond that, the Inverter switches from charge mode to INVERT mode to assist the generator)

Generator Support PLUS Enabled

Set your voltage and freq's to your personal choices.

Yea I think the big flywheel lister and st head might do better on surges than my yanmar.
I worked pretty good, until the wife turned on the electric oven @ 4500 watts. It would disqualify the gen, then requalify,until the oven thermostat started cycle Then about time it re sync's the oven would kick on again and so on and so on.
Works flawlessly now.
