Wrenches/Hilton Home run connections, confirm brand, had issue where it needed more volts to overcome the poor connections. You will need to be on site with at least two techs and check each homerun first but l have had module to module issues. I have also had internal issues at the Jbox some brands are just pushed in and don't seem to work well. Got to love PV
