I'll be looking into this to try and find out if this was indeed the issue people were running into. I'll be honest - I've asked very specific questions to our manufacturer about these units with somewhat vague responses, and I've always done my best to answer on here with all the info I was given. We have recently taken to completely re-writing manuals (like for the new inverters) in house from the ground up, and going through a very structured testing process on site. This is something that will be going into more depth with the batteries as well. I've really pushed to have much better documentation and training available for tech support and customers - I hope you can all see that we are growing and getting better. I'm only one small part of a large team that is taking the helm for this process. Re-writing the battery manuals, learning everything about them down to the circuit boards and programming is next on our list.
