Batteries not communicating

04/20/26 our system was running fine, we are told by SignaTech that an employee of EG4 changed our battery settings from lithium to lead acid or vis versa, when they did this 2 of our batteries failed.  SignaTech contacted EG4 and they replaced the batteries.

Since this has happened our batteries are not communicating with each other, and we are told that the inverter may need to be replaced.  

I have been in contact with Lelia Cavillo, but last communication was about 3 weeks ago.  I have since sent 2 other emails with no response.  Our last email was she was getting with upper management and going to contact SignaTech.  I have not heard from anyone.  I have also cc’d James Showalter and he has not acknowledged my emails either.

I would greatly appreciate getting this resolved.  Also we are being billed from SignaTech for something that we should not be responsible for.
