FAQ
All rechargeable 12V batteries
The OBD-II connector allows the solar panel to charge through a vehicle's On-Board Diagnostic Port. This method of charging is ideal as the OBD-II port is always live.
For safety reasons, the solar panel should be stored while the vehicle is in motion as any distraction to the driver can be dangerous.
No, anything below 15W will not overcharge a standard automobile battery.
No, a solar battery charge controller is only needed for panels of 15W or greater.
A trickle charger is designed to slowly increase a battery's voltage, offsetting any natural decrease. The actual time to charge a battery is governed more by the size and condition of the battery than the trickle charger.
To measure the voltage of the panel, use a voltmeter. The open-circuit voltage reading should be between 16 and 25 volts in full sun (not connected to the battery).
