No, this kit comes with a solar charge controller which if used correctly will ensure your battery charges correctly and safely.

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).

There are many elements in this calculation. The size of the battery capacity and availability of sun are the two most important considerations.

Yes, all connections must be in parallel (positive to positive, negative to negative) to maintain a 12-volt system. Additional connection cables are available through the Sunforce website (www.sunforceproducts.com).

Yes, the solar battery charger comes with mounting hardware. Quick twist brackets allow for secure permanent mounting.

Yes, the only limitations are your batteries must be configured to supply 12 volts

Amorphous solar panels have the ability to provide power under overcast or low light conditions. This makes Amorphous technology ideal for battery charging in a wide variety of applications.

The solar panel is fully weatherproofed. The solar charge controller must be kept in a dry well ventilated location.

Yes, as long as you use the solar charge controller you can safely leave this solar charging kit connected to your battery.
