Here you will find answers to commonly asked questions about your solar power system. Please be sure to note the Transcend XPLOR specific details on some answers if you are a Transcend XPLOR Owner.

Anything from Lead-acid to AGM are appropriate for solar.  Lithium Iron Phosphate batteries can be utilized, but may require a different converter.

We use Furrion connectors or MC4 sized connectors.  Check your roof mounted solar dock to confirm.

The size and number of panels that you can install depends primarily on the controller.  Grand Design uses controllers from 25A to 50A.  Work with your dealer to ensure additional panels are utilized most effectively.

Coupled with a 2,000 watt inverter (translating to nearly 17 amps), all 12V components, your refrigerator, and nearly every outlet in and on your camper provides many options for off-grid use.*
*On Transcend and select Imagines and Reflections, there is no inverter option.

Yes.  Solar plus tow vehicle charging allows more than enough power to keep your food cool in a residential style 12V DC refrigerator.

We recommend quality monocrystalline panels from our vendors, which provide the most efficient power for the available.

Absolutely!  Multiple controllers can be installed in a parallel circuit to provide extra charging power to your batteries to support both 12V and 110V usage.

Keep them clean and scratch free and free from debris to maintain maximum charging power.

Yes, an inverter, transfer switch and circuit panel will allow 110V access for outlets and your refrigerator. This should be done by a qualified technician due to the complexity of the wiring and need for an additional sub-panel.
 *Select Reflection models include an integrated sub-panel for convenience.

A unit built with solar comes with 2 battery bays from the factory to provide space for 12V group 27 batteries.

Yes.  Simply make sure that your additional batteries are of the same age and type, whether it be lead-acid, AGM, or lithium.
