LVD after charging with generator
Just used my backup Iota 45 DLS charger for the first time. The batteries were down to 60% and no sun on the horizon so I rolled out the generator and plugged in the charger. In a little less then 2 hrs the batteries were back to 90%. When I returned two days later, after a sunny day, the batteries were still at 90%. I checked the control panel and saw that the charge controller was blinking red, indicating a low voltage disconnect (LVD). I rebooted the system and all is fine now. Can anyone explain why using the Iota charger would trigger the PV charge controller to LVD ? The Iota is hardwired to the battery bank.
