 FireFly Ultralight - Hard Case

     This Portable Solar Power System can be carried during events where high energy density and minimal weight are critical, and is best suited to provide power for small portable electronics.  To reduce the weight of the system to a bare minimum, the components have been trimmed down to the essentials, and the configuration is one of open architecture.  The system can power a variety of portable electronic devices that require 12 volts DC up to 8 amps/88 watts, 5-volts USB up to 2.1 amps, and can recharge itself in sunlight using the included solar panel.  If the power draw on the battery is 20 watts, the battery will last approximately 2 hours in the absence of incoming solar power before it needs to be recharged.  The battery assembly, solar charge controller, solar power input connector/cable, and 12-volt female cigarette lighter socket/cable are housed inside a waterproof hard case.  The solar panel, USB adapter, and AC-powered battery charger remain outside of the pack.  12-volt DC power is accessible via a female cigarette lighter socket that is protected by the protective circuitry of the battery pack.  5-volt USB charging power is provided by an adapter that plugs into the cigarette lighter socket.  If the power draw on the battery exceeds 8 amps, power from the battery pack will be interrupted until the load is removed.

     FireFly Ultralight - Hard Case includes: Battery - a rechargeable, 11.1-volt, 4.25 amp-hour, 47.17 watt-hour, lithium ion - polymer battery pack that will tolerate > 500 discharge-charge cycles @ discharge current < 0.5C (2.125 amps/23 watts).  The protective circuitry module protects the battery against over-charge, over-discharge, short circuits, limits the maximum discharge current to 8 amps, and performs a balancing function on the cells of the battery pack.  The battery can be charged directly from the solar panel via the solar charge controller, or via the smart, 1.5-amp, 100-240VAC-powered charger when the grid is available (4-4.5-hour charging time).  To charge the battery pack, the AC-powered battery charger plugs directly into the cigarette lighter socket; Fuel gauge - the battery pack comes with a push-button fuel gauge that indicates the state of charge (remaining energy) of the battery pack via a series of red LED's; Solar panel - CE-certified, foldable 6-watt/300-milliamp unit that will require 9-10 hours of peak sunlight to completely recharge the battery if it is depleted, and that measures 20.63 x 11.25 inches when unfolded, and 11.25 x 8 inches when foldedSolar Charge Controller - 4-amp/50-watt MPPT unit that is configured for 11.1-volt Li - ion polymer batteries, and that has a “resting” power consumption of 0.09 milliamps.  If the system is stored for a prolonged period of time, the battery pack should be charged every 2-4 weeks in order to avoid complete discharge; USB adapter - plugs directly into the cigarette lighter socket, and has two standard female Type A USB charge ports, one that provides 1 amp of current, and the other that provides 2.1 amps of current for your power hungry iPad; Hard case – Mil-STD 810F 512.4 and IP-67-certified water, dust, and crush-proof hard case that measures 8.75 x 7.5 x 3.88 inches in external dimensions.  


     The complete system weighs 4.2 pounds.  The AC-powered charger will not be needed when the system is used off-grid.  Leave the AC-powered charger behind, and the system weighs 3.3 pounds.


     Each of these systems is custom-made as needed.  Please allow 2-3 weeks of lead time per order.
