This System Has Been Upgraded to Version 3. Click Here To See The New Design

This is a elegant portable solar power generator system that is using the latest technology available.

This system has a "Lithium Iron Phosphate" LiFePo4 battery which has a capacity of 100 Amp Hours / 1280 Watt Hours. The weight of the main case is 60 pounds which is great when you compare it to competitors 100Ah systems that use old heavy battery technology called AGM or Lead Acid Batteries that weigh in a 100+ pounds or 40 more pounds over the LFP system you see here. The battery is also rated to provide 2000-3000 full charge/discharge cycles before they start storing less power than their rated capacity which is great compared to the heavier AGM batteries that when 80% of the energy is taken out of the battery every day will only last 300 cycles vs 2000 that LiFePo4 batteries give you. The LiFePo4 battery also contains no toxic ingredients which is good for the earth. The battery will not ignite, explode, or catch fire which is the opposite of other more dangerous Lithium batteries like Lithium Polymer or Lithium Ion batteries that can ignite and violently explode under certian conditions. The last advantage that LFP batteries offer is that they usually provide right at 100% of their rated capacity when large amounts of power is pulled out of the battery, so you get 100 Amp hours / 1280 Watt Hours from a fully charged battery if you pull 1000 watts continuously until the battery is dead compare that to a lead acid battery that would only provide 60-70% of their rated capacity under that same 1000W load, with AGM batteries that 30-40% just disappears and you never get to use or enjoy it.

 This system can be recharged via a included 20 Amp AC Charger that can be plugged into any 120v AC wall outlet to recharge the battery from empty to full in about 5 hours. The system can also be recharged via solar power by plugging in solar panels to the solar input port which can handle 200 Watts of solar charging continuously from folding or regular glass solar panels if desired. Glass solar panels are cheaper but are more fragile and weight much more compared to the folding solar panels so it just depends on your budget and needs which panels are best for you. This system is shown with two 72 Watt folding solar panels but it can be used with up to three 72w folding solar panels if desired. You can hook the system up to a solar array that is larger than 200w but the system will only use 200 watts to charge the battery at any given time. When the 72w solar panels are not available we will substitute them with these 62w solar panels

 The solar charge controller uses Maximum Power Point Tracking technology that constantly maximizes the output of any solar panel array that is connected to this LFP 100 System. What Maximum Power Point Tracking does is constantly measure the Open circuit voltage of the solar panel and then sweeps the whole voltage output range of the solar panel to see at witch voltage the panel is producing the maximum amount of power then the charge controller locks the voltage of the panels at that voltage so you get maximum power out of the panels. This process is repeated constantly any time the solar panels are hooked up and sunlight is available. This Maximum Power Point Tracking  process can give up to a 30% increase in daily solar harvest when compared to other systems that do not use Maximum Power Point Tracking on the solar input. If you are using a system that does not use Maximum Power Point Tracking then you are not harvesting all the power you could be and you end up with less power over the course of the day. 

 There is a compact 1250 Watt AC Power Inverter inside the case that has 3 regular US style 120v outlets that you can plug in your AC equipment. The 1250 Watt AC inverter is a Modified Sine Wave Inverter that has a very simple ON/Off switch beside the 3 AC outlets to turn the inverter ON or OFF when not in use. The inverter has 2 fans on the right side of the case that run constantly while the inverter is on to keep the inverter cool. There is a green LED that is displayed when the inverter is ON and power is available from the battery. There is also a red LED beside the green LED that will display when any error occurs like Over Heating, Over Current, Short Circuit, Over or Under Battery Voltage. This a very simple and easy to use inverter that was chosen because of its compact size that could be fit inside the case. Other inverters can be used with this system by hooking them up to the Cigarette Lighter Outlets or the main remote 12v battery terminals on the front of the case which can supply up to 150 Amp @ 12v DC. 

There is electronic digital battery protection built into this system that provides effortless battery protection for Under Voltage, Over Voltage, and Short Circuits if they were to ever occur. Their is a simple ON / OFF latching push button with a green LED on the top panel of the case and this button is used to turn the 12v output ON or OFF, when the 12v output is ON the Green LED is illuminated to indicate that the battery is charged and there is 12v Power being supplied to the ports. When the battery becomes fully discharged the output from the battery will be disconnected to prevent over discharge and the green LED on the button will turn off. To reset the output to begin solar or AC charging just push the ON / OFF switch down and then back up and power will be restored and charging can begin. If there is a short circuit fault can be rest by this same process. 

The most unique feature is the digital battery monitor that displays the following:

  • Current SOC "State Of Charge" of the battery from 0 to 100% at any given time.
  • Consumed Energy in Amp Hours from 0 to 100 Amp Hours.
  • Battery Voltage
  • "Time To Go" - This calculates the Hours then minutes left until the battery will be fully drained based on your current power consumption. 
  • History - Logs the history of the battery usage pattern like average discharge level, deepest discharge level, times the battery has been fully charged, days since the battery was last discharged and many other parameters which are helpful to gauge the expected lifespan of the battery. 

There is a small Bussman fuse box to the right of the 1250w inverter that houses the resettable breakers for the solar charge controller and the 2 cigarette lighter outlets which are fused for 15 Amps each. No fuses are needed all that is needed in the event that a over current situation occurs and causes a breaker to trip is to push the reset button on the breaker and power will be supplied again to the affected output port. No need to ever seek out replacement fuses. 

The LFP 100 main system case weighs 60 pounds. The AC charger weighs 5 Pounds. The 72w Solar Panels weigh 7 Pounds each, the alternative 62w solar panels weigh 3.1 pounds each.

This system is custom built by hand in the USA and depending on our current production capacity, the ship time for this system can be anywhere from 4 to 8 weeks to build the system, test the system, and then ship the total package.
