OPERATIONS
POWERmini optimizes the life of the battery by protecting the battery from overcharging or excessive
discharge. It accomplishes this by constantly monitoring the battery voltage and solar panel voltage and
determining the state of charge of the battery.
POWERmini USB is a programmable device allowing you to configure it to use with different types of
battery.
User settings include
• Low battery voltage trip point, reset point and early warning of low battery
• Automatic disconnect – provides protection from deep discharge
• Max charge voltage -customize to suit specific battery
• Over voltage trip point and reset point
This section provides information about how to get the most out of your POWERmini.
