Reliability at the same time. The instructions are numerous and helpful. There was no problem connecting a 12V LiFePo4 battery pack to the 300W solar panels connected in series. Runs like a champ. There is a slight change in charge cycle voltage, but we knew it was included in this project. Do yourself a favor and get a remote WiFi monitoring add-on. It allows you to use a laptop to set all the parameters. Hopefully it will last us years.
