New system working perfectly until I switched off panels on battery switch

  1. I have a 400w panel on a battery switch inputting to a SmartSolar 100/30 and connected to a 200ah battery.

I just got everything hooked up and it was working perfectly for a few hours before I got curious and decided to test the photovoltaic battery switch I installed to see what happens when I cut the power to the Victron unit. It disabled the current perfectly!

when I turned the switch back on I noticed that it went into bulk charge mode and was showing over 40v on the panel but is showing zero amperage charging the battery. The battery voltage is still showing up just fine, but it’s not increasing.

It looks like I somehow messed up the charging by turning off the switch and turning it back on again. Any suggestions for how to reset this and get it working again?
