Guest (Jim),
While testing today I ran into my previous problem--the system sees a low battery condition and shuts down. As in completely off.
I'm really not too surprised as I made a LOT of changes in a very short time without methodical testing after each change. AMSolar won't assist me and Victron won't talk to the end user, so I get to figure this out myself. I actually enjoy working this type of problem, so it's just a matter of having the time and careful documentation.
I removed the ESS and reloaded AMSolar's standard configuration in the Multiplus so I have a known starting point. I also disconnected the Renogy's output from the Multiplus. (It's off so it shouldn't be causing a problem, but best to remove all the variables as I step through this problem.)
I then loaded down the inverter and I had it run both air conditioners, the microwave AND the toaster oven before the inverter went into overload. The batteries, however, continued to send power and the system did not shut down. So it is something in the ESS and/or DVCC settings. I was surprised by how low the battery voltage registered while under the heavy load (see below). That's definitely a clue to my issue.
After confirming everything worked as expected again, I re-enabled DVCC (only). One item I changed from the previous config is I did not enable LIMIT CHARGE CURRENT. The Battle Born BMS is protecting the batteries from drawing too much current, so why choke down my solar and inverter if power is available?
The only option that is enabled is SVS - Shared Voltage Sense. I know the BMV and SmartSolar are networked over VE.Smart Networking, but I need to read more about that network to understand that capability better.
Thanks for following along.
