U.S. Published Application No. 2003/0105556, for example, discloses a method and device for using wind to supply uninterrupted power to a location not served by a power grid. However, that invention only uses wind energy that may be stored as compressed air and it does not provide for portability. 
         [0006]    U.S. Publication Application No. 2012/0201016 shows a solar-powered device with a mobile base unit, a power module that converts solar energy to electrical current and a lighting module powered, directly or indirectly, from that electrical current. By contrast, the present invention uses a photovoltaic solar array, standby generator and optional wind turbine to charge its battery system. In turn, that charged system provides the source of all power for running outdoor floodlights and/or an AC electrical panel. 
         [0007]    U.S. Pat. No. 4,206,608 discloses a system for storing and generating electricity using solar, wind, and wave energy. But, it has no reference to portability.

No. 4,261,329 discloses a portable housing module with a thermal unit that extracts heat from the sun to a heat exchanger and a photovoltaic unit that extracts photons to create electricity. That module is not integral to its trailer, however. It merely carries the unit from point A to point B.

         [0010]    U.S. Pat. No. 5,969,501 discloses a box-like portable solar power system that is not severable from its trailer. It uses adjustable support braces to position its solar array. The present invention, on the other hand uses a DC electric linear actuator for solar array positioning.

       SUMMARY OF THE INVENTION 
       [0017]    The present invention comprises a mobile power platform which can start storing energy to its batteries while in transport. It uses an array of photovoltaic cells in panels that fold for easier transport before fully deploying at its designated use site. That solar panel array is preferably greater than 640 watts and optimally between 1000 and 32000 watts. The system can be positioned in the direction of the sun with efficient, cost effective means. The assembly further comprises a stand by/back-up generator powered by gas, diesel, propane or natural gas along with several batteries in a weatherproof box for storing the energy generated by its various power energy units. The assembly may further include a communications system. 
         [0018]    The lightweight assembly is transportable to locations where energy is needed, including remote locations. It includes an inverter for providing electric power to a weatherproof panel permanently mounted onto this transportable assembly/trailer unit. 
         [0019]    The invention further comprises a method for providing portable, renewable energy. That method comprises the steps of: providing the aforementioned power system, disposing that system on a transportable platform, and commencing the storage of usable energy while transporting that system to an end user site. The platform system easily transports to one or more locations where energy is required, even remote locations. It is relatively lightweight yet durable. It enables connecting for the extraction of energy stored in a plurality of rechargeable batteries. 
         [0020]    A primary object of the present invention is to provide a renewable energy unit that is capable of starting to store energy while in transit. Other objects, advantages and novel features of this invention will be set forth in part in the detailed description to follow, taken in conjunction with the accompanying photographs of a working prototype.

     DESCRIPTION OF PREFERRED EMBODIMENTS 
       [0029]    Referring to the accompanying  FIGS. 1 through 3 , there is a shown a mobile (or semi-portable, by towing) power platform, generally  10 , with an AC (and, optionally 12, 24 or 48 VDC) power source that uses a plurality of foldable photovoltaic solar panels  12  hingedly attached to a flat towable trailer  14 . Optionally, it includes one or more racks of floodlights  16 , a small wind turbine component  18 , one or both that attach to an extendible pole or mast  20  and/or a kinetic charger optional mechanism  22 . Note that, when referring to any numerical part size and/or power delivery capacity, representative values may be expressed as precise numbers or between a range of numbers (a minimum to maximum). All such values are truly representative and this invention should not be restricted to a device only X feet long, weighing Y pounds and products Z units of power. Furthermore, when any range is cited below, it is to be understood that every such range includes every value between the stated minimum and maximum. For instance, a panel measuring between about 24 to 42 inches wide, each, would also cover panels that are about 24½, 25 and 27¾ inches to about 35, 37 or 39.95 inches wide, said panels also being between about 40 to 66 inches long. 
         [0030]    One particular embodiment includes a 22 foot long, 102 inches wide “deckover” dual axle trailer  14  with a GVWR of 7000 lbs. That trailer includes 4 drop-leg leveling jacks  24  at its four corners (though only two are visible in these views). Bubble levels (not shown) may be permanently mounted onto the front and rear of the trailer frame for assisting with manual leveling at each end user site. 
         [0031]    An aluminum frame  26  holds a plurality of photovoltaic solar panels  12 . That frame  26  is permanently attached to one long edge  28  of trailer  14 . Frame  26  includes a hinge  30  that runs lengthwise over the center width W of trailer  14 . The unattached side  32  of that frame  26  secures to an opposite (long) trailer edge  34  with two spring loaded, locking pins  36 . After releasing these pins  36 , the photovoltaic solar panels  12  on hinged frame  26  can be positioned to an open or fully deployed state (see  FIG. 2 ), using 12 to 48 VDC electric screw actuators  38 . Preferably, the proper positioning of frame  26  is controlled by a pendant station  42  connected to the lift controller cabinet  70  at or towards the front of trailer  14 . Support posts  40  are used to stabilize the frame  26  in the fully deployed fixed position state. 
         [0032]    As best seen in  FIGS. 1 ,  2  and  3 , the hinged frame  26  of solar panels  12  stores in an “A” configuration during the transport of trailer  14 . It then opens to a flat plane for operation (i.e., when stationary). An inclinometer (not shown) mounted on hinged frame  26  shows the angle of the solar panels for operational optimization. 
         [0033]    In the accompanying FIGS., the representative device  10  is shown with two rows of panels, with six panels per row. It is to be understood that fewer or greater numbers of panels may be joined together in alternate embodiments of this invention depending on trailer size, towing weights and/or power output needs of the customer (either a purchaser or event lessee). One representative manufacturer of such panels is SolarWorld (company), though substitute models are also made and sold by SunPower, or LG Solar. 
         [0034]    Preferably, the solar panels  12  for system  10  secure to both sides of hinged frame  26  with weather stripping and aluminum “C” and “I” channels. All of said panels electrically connect to a fused combiner box  44  mounted on the main or top deck  46  of trailer  14 . 
         [0035]    There is a power controller cabinet  48  mounted onto deck  46  of trailer  14 . It contains the photovoltaic solar battery charger  50 , DC-to-AC inverter  52 , gateway communication controller  76 , power fuse block for AC and DC electrical terminations  58 , optional wind turbine controller  54 , optional kinetic generator controller  56  and optional GSM communication modem  78 . 
         [0036]    A power storage cabinet  60  also mounts to trailer deck  46 . It contains a “bank” of four or more 225 amp-hour batteries  62  in a 12, 24 or 48 VDC configuration. An outlet (now shown) is provided on the outside of power storage cabinet  60  for providing 12, 24 or 48 VDC power directly to DC devices or to charge the aforementioned battery bank with an external charger (not shown). 
         [0037]    Within power storage cabinet  60 , the batteries  62  are connected to electrical power distribution blocks (not shown) with fused connections (not shown) for each positive electrical termination. The batteries  62  connected through the power distribution blocks (now shown) are electrically connected to the power fuse block for AC and DC electrical terminations  58  in the power controller cabinet  48 . 
         [0038]    The solar panels  12  are electrically connected to the fused combiner box  44 . The fused combiner box  44  is electrically connected to the photovoltaic solar charger  50  in the power controller cabinet  48 . The photovoltaic solar charger  50  is electrically connected to the batteries  62  through the power fuse block for AC and DC electrical terminations  58  in the power controller cabinet  48 . 
         [0039]    The DC-to-AC inverter  52  in the power controller cabinet  48  electrically connects through the power fuse block for AC and DC electrical terminations  58  to that same bank of batteries  62  in power storage cabinet  60  and an electrical power panel  64  mounted to the front of trailer  14 . One embodiment of inverter  52  is designed for continuous 4000 Watt output at 120/240 or 230 VAC for at least about 18 hours when the batteries in bank  62  are fully charged. 
         [0040]    A standby generator  66  may be mounted to the top deck  46  of trailer  14  to provide up to 4000 Watt output at 120/240 VAC when the voltage for battery bank  62  drops below a configurable threshold voltage setting. The configurable threshold voltage setting determines the automatic startup and shutdown of the standby generator  66  through the generator controller cabinet  68 . When standby generator  66  is running, the electrical load is handled by the generator while also charging battery bank  62 . 
         [0041]    A system status display in the lift controller cabinet  70  mounts to the front of trailer  14 . It provides information on the charge level for battery bank  62  and its inverter  52  output capacity. Preferably, that display cabinet  68  also includes an emergency shutdown button (not shown). An optional cellular communication modem  78  can be included within power controller cabinet  48  for remote monitoring and reporting on overall performance of system  10 . 
         [0042]    In  FIG. 2 , an optional telescoping mast  20  with outdoor flood lighting  16  is mounted to the front of trailer  14 . Mast  20  can be raised or lowered with the pendant station  42  in the lift controller cabinet  70 . The telescoping mast  20  is shown configured with four 98 Watt LED floodlights with photoelectric cells though alternate variations may include two, six or odd numbers of lights as well. Regardless, mast  20  MUST be completely lowered for travel/transport, however. 
         [0043]    An optional 600, 1000, 2000 or 3500 Watt wind turbine  18  can be mounted to trailer  14 , either using the same mast  20  as above or through its own, stand-alone telescopic mast pole. Like the aforementioned light tower mast, any separate mast for wind turbine  18  must be completely lowered for travel. Note that in some instances, the outdoor flood lighting and wind turbine can be combined onto a single telescoping mast. 
         [0044]    One such wind turbine option comprises conventional a wind energy machine known as a horizontal axis style wind turbine with a plurality of blades  74 . That wind energy system would mount on its tower for extending up to about 20-40 feet high when fully deployed. Wind energy is particularly useful to provide supplemental power to the system at night or during especially windy days. Conversely, during the seasonal longer hours of available solar energy generation, there would be less need/reliance on the wind energy (optional) components hereof. 
         [0045]    The energy produced from the solar panels and/or wind system transfers to deep cycle batteries that can store the energy. Preferred batteries are industrial grade, deep-cycle, maintenance free, gel-cell batteries that do not need to be checked and do not need additional water added. Representative makers/sellers of such batteries include Deka and Concorde. Such batteries will be enclosed in a power storage cabinet  60  for keeping the batteries safe, yet functional over a set range of temperatures. 
         [0046]    Preferably, the platform  10  further comprises a standby generator  66 , such as a propane-powered, natural gas or other hydrocarbon-powered generator, along with a fuel tank  72  for storing the fuel needed to run generator  66 . One representative generator system uses a storage tank  72  with a 100 lb./23 gal. capacity. 
         [0047]    It is only intended for that generator to operate at peak for short periods of time to maximize overall efficiency and extend battery service life. If that generator had to provide additional run time to compensate for reduced wind speed or solar insolation, it still should be able to handle it with little to no additional stress. Consequently, if loads are reduced, virtually no generator usage would be required. 
         [0048]    The Figures also show an optional kinetic charging component with its generator component  22  situated at or near the towing wheels for trailer  14 . They connect to a generator  56  within a control box for the system proper. 
         [0049]    The assembly and system of this invention should be virtually maintenance free. The trailer unit itself is a compact size and relatively lightweight for transport and deployment at most any remote location. It can be deployed, once at its end use location, by just one person. The system offers a substantial fuel savings over an equivalent fossil fuel generator standing alone. 
         [0050]    For greater stability against potential wind damage, multiple anchoring devices are incorporated throughout. Once delivered, this assembly and system are completely operational. Unlike other known systems (described above), this invention has the added benefit of being able to commence energy storage through its photovoltaic cells and into its battery storage “packs” while being transported to its eventual end user site. The only on-site construction might involve the erection of its optional light mast, wind tower and/or telecommunications equipment, all of which are permanently attached to or erected near that end of the platform from which all electrical connections are made to its adjacent inverter. 
         [0051]    For the comparative chart at  FIG. 4 , fuel costs used a generator calculation based on diesel fuel at about $4.15/gal. and propane at $2.33/gal. based on a 365 days/24 hours per day usage. The side-by-side comparison did not take into account fuel delivery or refueling costs. It was noted, however, that a standard 6 kW diesel generator might require refueling as often as 2 times/week as compared to the MP-4000&#39;s use of a 100 lb. propane tank requiring refueling only once every 3 months. With the aforementioned fuel cost savings, fuel delivery AND refueling costs, it is expected that financial payback from use of a system like that of the present invention can be achieved as quickly as 18 mos. or up to 3 years depending on its frequency of use. 
         [0052]      FIG. 5  schematically shows one preferred arrangement of battery storage units, in a weather resistant case/cover.  FIG. 6  depicts one schematic cabinet, in perspective view, showing various subcomponent-controllers for use with the system; and  FIG. 7  schematically shows one representative embodiment of kinetic generator device beneath the trailer deck, between its wheels, per one embodiment of this optional addition to this invention. 
         [0053]    One representative model of Mobile Power Platform according to this invention consists of the following components:
       1. Trailer—Used to transport the solar generator to location where power is needed. Other major components are secured to the top deck of this trailer. They include a solar panel frame system, telescoping mast system, battery cabinet, charger/inverter cabinet, lift control cabinet, generator control cabinet, photovoltaic combiner cabinet, fuel storage (single gasoline tank, single diesel tank or propane tanks) and generator/cage. One preferred trailer deck is at least 6 feet wide, (no wider than 8 feet, 6 inches) and from 8 feet to 32 feet in length for a standard tow-behind trailer, or up to 53 feet for a drop deck semi-trailer.   2. Battery Cabinet(s)—Contains 12 Volt batteries (possibly connected in series to produce 24 or 48 volts) in parallel to store energy produced by solar panels, optional wind turbine and optional kinetic generator. Each parallel battery circuit is connected to a fuse (to allow battery replacement without completely shutting down the energy storage system), then to a power distribution block (one for positive battery connections and one for negative battery connections). The power distribution blocks are connected through a conduit to a fused AC/DC connection electrical blocks in the charger/inverter cabinet(s). Battery cabinets include a temperature sensor, a thermostat and at least 2 fans to provide airflow and cooling inside the cabinet. Additional fans installed in the cabinet are optional for environments consistently operating above 90° F. A heater installed in the cabinet is optional for environments consistently operating below 32° F. The standard thermostat only runs the fans for cabinet temperatures over 90° F. and only runs the heater to keep cabinet temperatures at a minimum of 40° F.   3. Charger/Inverter Cabinet(s)—Contains the DC-to-AC inverter, the AC/DC electrical connection blocks, the photovoltaic solar charge controller, the remote communication controller, the optional wind turbine charge controller, the optional kinetic generator charge controller and the optional solar panel frame system single axis tracking controller. The DC-to-AC inverter is connected through a conduit to the electrical power safety panel to provide AC output power. Charger/inverter cabinets include a thermostat and a sealed fan/heat transfer unit (NEMA 3R rated) to provide airflow and cooling inside the cabinet. An additional sealed fan/heat transfer unit is optional for environments consistently operating above 90° F. The standard thermostat only runs the sealed fan/heat transfer units for cabinet temperatures over 80° F.   4. Lift Control Cabinet—Contains the solar panel frame lift controls, a retractable pendant station (pushbuttons and selector switch), the system status display and a system-wide emergency shutoff switch. The pendant station has a selector switch (solar array, telescoping mast, track and off position), two pushbuttons (raise and lower) and a retractable cord to extend the lift controls to a safe position away from the trailer during operation. The system status display provides information on the charge level for battery bank and operation of its charger/inverter output. The emergency shutoff pushbutton switch deactivates all power to the system. The optional telescoping mast lift controls are also contained within the cabinet. The lift controls and emergency shutoff switch are connected through a conduit to the charger/inverter cabinet AC/DC connection electrical blocks. The lift control cabinet is mounted on the deck at the front of the trailer.   5. Solar Panel Frame System—Provides the mounting for the solar panels and positioning of the solar array. The solar panel array is positioned with linear electric actuators connected to the main frame, support beams. Extendible support posts are used to provide stability for fixed positioning of the frame system. An optional single axis, tracking computer (mounted in the charger/inverter cabinet) can automatically position the frame by tracking the sun&#39;s path from east to west. The solar panels are electrically connected to a photovoltaic combiner box also mounted on the trailer deck.   6. Telescoping Mast System—An optional component that provides the height extension of the optional wind turbine, optional LED floodlights, optional security devices (cameras, motion sensors, infrared lights) or combination of any of these options. The telescoping mast system includes a pneumatic compressor, electric winch or hand crank to extend and collapse the mast. For the pneumatic controlled mast, an air compressor and electronic valve module is added. For the electric winch controlled mast, an electric winch motor is added. The pneumatic compressor and electric winch are controlled with the pendant station raise/lower pushbuttons connected to the lift control cabinet.   7. Kinetic Generator System—An optional component that charges the battery system during transport. The kinetic generator system includes a drive shaft with small wheels, a motor/generator, a clutch mechanism to engage/disengage the motor/generator and a charge controller. The small wheels make contact with the trailer wheels to turn a shaft with a gear. That gear turns a motor/generator to generate DC electrical current to a kinetic charge controller. The charge controller regulates and conditions the electrical current from the motor/generator and connects to the power storage system. The charge controller also disengages the motor/generator when the power storage system is fully charged. The motor/generator is mounted under the trailer deck and the kinetic charge controller is mounted in the charger/inverter cabinet.   8. Wind Turbine Generator System—An optional component that charges the battery system in addition to the photovoltaic solar charging system. The wind turbine generator system includes a wind turbine generator and a wind charge controller. The wind turbine generator is mounted on top of the telescoping mast and the wind charge controller is mounted in the charger/inverter cabinet.   9. LED Floodlight System—An optional component that provides lighting at night at the remote location. The LED floodlight system includes 2 or 4 LED floodlights with photo cells and a switch box to control which lights are used. The LED floodlight system is mounted on the top of the telescoping mast.   10. Standby Generator System—An optional component that automatically charges the battery system when the battery discharge level reaches a configurable charge level. The Standby Generator system includes a gasoline, diesel, propane or natural gas fueled generator, fuel storage tank(s), a generator start controller (in the generator controller cabinet) and an emergency generator shutoff pushbutton switch. The standby generator is connected to the inverter in the charger/inverter cabinet. The generator can also be disconnected from the inverter to provide additional power while fuel is available.   11. Generator Control Cabinet—Contains the generator start/stop controller and a system wide emergency shutoff switch. The emergency shutoff pushbutton switch deactivates all power in the entire system.
