The easy thing to do next time is to configure the gen start setting for 15 seconds. You have the 15 minute and 2 hours but from what this sounds like, you need to set the 15 second to around 24V.
Then, you can add the combox or the new gateway and troubleshoot. The "picture" from the battery summary screen is hard to beat. It shows you what happened and seeing this screen is a notch above data logging, in most cases. This is why it is a mistake to use another brand of charge controller as the solar data is missing on this screen. All the shunts are internal to schneider devices for the picture. Faster to install and better in my opinion.

I carry one in the truck but a good idea to leave it on site. On Wed, Nov 20, 2019 at 7:33 AM Maverick Brown wrote: The COMBOX is a great addition. It has a detailed seven day black box style recording of all the parameters, even if it not connected to the internet You can zoom in and see the battery voltage and current through the inverter. And you can read errors and warnings for each Schneider device. Plus, the COMBOX can record parameters to a SD card for later retrieval. I usually also add a low cost router so I can just jump on the COMBOX when I arrive to see what's been going on. When I do that I also set a fixed IP address on the COMBOX.

The only monitering is through the scp or the classic charge controller via whizbang Jr shunt. I am thinking about adding the combox but not sure how helpful it will be since there is no internet or cell service at this site.

It will record lowest voltage since last reset. Would help in diagnosing the problem. Jay On Nov 19, 2019, at 6:06 AM, Aaron Mandelkorn wrote: Thanks all for the info. I did check the auto gen start settings and and they are set pretty high and at the 15 min, 30 min, and two hr triggers all above the LCBO setting of 23v. I have hard time believing that the system is crashing at night due to low battery and doing so so quickly that the gen isn't coming on. Could this be an issue of temporary voltage drop triggering the LCBO due to a large load coming on at night? Why would these events not be in the log and why isn't the generator coming on? A seems to work during the day and when I come out there to test.
