I bought one of these . it the second one I,ve owned
The unit also automatically disconnects the battery if the terminal voltage drops below the selected Voltage (user selectable), and then reconnects it once it is charged again.
It features an LCD panel that displays battery voltage, the solar panel voltage and the active charge mode.
"Unlike other regulators, you can see the true status of the charging system at a glance".
