Frequently Asked Questions
Green Duck Thin Film Solar Modules
How do I know which size I need?
It really depends on how
much power your device uses. You can usually look on the back of
your electronic device or on the plug for information regarding how
much power you need. What you are looking for is the number of
Amps...and then consult this charging example chart:
How do I know if it is working?
You can check the Rollable Battery Charger with a voltmeter.
Will this product drain my battery at night?
No. It has a built-in blocking diode to protect against reverse draining of current.
Can I leave it outside permanently?
The Rollable Battery
Charger can be left outside permanently if maintained properly.
It must be properly secured to avoid damage from high winds.
Terminals should be kept clean and firmly connected.
What if the product gets wet?
No problem. The product is waterproof.
What if the product goes under water?
Simply wipe the product
with a dry cloth and allow the product to dry before use. Avoid
having the product completely submerged for an extended period of time.
Can I leave it outside in freezing temperatures?
Yes.
If I need more power can I connect several of these together? How?
Yes, it is acceptable to
connect several Rollable Battery Chargers in parallel. Connect
using the Rollable Daisy Chain Accessory. Connect chargers up to
a combined output of 20 Amps.
Can I use an extension cord?
You can use the 15 ft.
Extension Cord Accessory complete with matching marine-grade
connectors. Total cord length greater than 30 feet likely will
result in reduced power output.
Do I need to disconnect this charger when I start my vehicle or when I recharge the battery with an auxiliary power source?
You do not need to
disconnect the rollable solar panel. You need to disconnect any
battery charger pack accessory that is connected to the solar panel.
Do I need a charge controller?
A charge controller is
used to prevent overcharging. As a general recommendation, a
charge controller should be used if the current output of the solar
panel, in Amps, is more than 1% of the battery capacity, in
Amp-hours. For example, a charge controller would be recommended
if the R15-1200 (with 1.2 Amps) were connected to a battery that is
less than 120 Amp-hours. Consult the battery manufacturer for
complete battery information and recommendations.
How do I clean the product?
Use a damp cloth with a mild soap solution.
