I am one of the developers of SerialTool and I noticed your post and we thank you for the appreciations on our software.
First of all I wanted to ask you first if you have resolved the issue.
Since this modem is not our product, we cannot provide direct support, but I can offer some suggestions.
The manufacturer of the module indicates the transmission speed from 300 to 115200 baud.
Typically, for these modules, you should connect to the serial port and send a series of repeated AT commands.
So, AT + [CR], then AT + [CR], and then again AT + [CR] until you receive an OK response.

At that point, you can send the remaining commands. If AT commands are properly implemented to any AT + [CR] you MUST get an OK as response and you cannot go any further until you'll get to this point.

Please let me know if you made it.


 

This story deserves to be turned into a movie!

No need to upgrade your inverter. Energy storage is not dependent on the Inverter to handle that storage. Eg. You can have a 5kW Inverter that has 100kWh of battery storage, the only question comes when designing such a system is how will you charge such a huge battery bank. 
In your case depends how many panels are attached to make it renewable from the Sun or will you accept Grid Charging as an option???
So simple answer no. Don't need to upgrade your inverter. But that depends on your charging & load requirements to fill up this larger battery. 

Hello @ZS1SCI,
I just registered on this forum to thank you for the amazing job that you have been doing!
Could you please give me a graphic of SOC vs BMS voltage for these batteries? Basically I just need see their voltage during one cycle of charging/discharging.
