Low Voltage Disconnect / Reconnect

The LVD/LVDR function of Morningstar controllers is designed to protect system batteries from overdischarge and (to a lesser extent) protect sensitive system loads from low battery voltage. When the battery drops to the LVD threshold, loads connected to the controller are shut OFF to give the batteries time to recover their charge. When the battery voltage rises above the LVDR threshold, loads that were previously disconnected are turned back ON. Low Voltage Disconnect/Reconnect does not affect the controller’s charging ability; charging continues whether in the disconnected state or in the connected state.
