Build your own power station - Part Two

In one of my previous posts on how to build your own power station ( http://www.preparedguy.com/2013/06/build-your-own-power-station.html ) I showed you how to build a very basic small portable rechargeable system that will run small devices and appliances.  This system is much larger, robust and versatile and is also meant to be portable.  I built this for a small cabin that is occasionally threatened by and was once destroyed by wildfire thus portability was important.  It is re-chargeable/renewable via solar panels, wind turbine, water turbine, gas generator and grid power.  This would be a great system to build for your home as a back-up power source for larger appliances, lighting, etc. that is not built-in to your home.  A reason that you may not want to add a solar back-up power system to your home is that it would then not be portable.  This system will allow for you to take it with you to a bug-out location.




This Portable Renewable Power System (PRPS) was built inside a standard job site box which can be locked and secured.  It is weather tight and can be operated outdoors or indoors with some ventilation.   Different sizes of these boxes are available.  You could also use most any type of box or enclosure as long as it will accommodate the components you desire.  I like using these job boxes for this purpose as they are virtually indestructible and can easily be secured to a tree, vehicle or other secure object with a large chain.




Standard residential solar components were used which make this system expandable, upgrade-able and easily repaired as needed.  In this picture you see the inverter/charger, solar charge controller, battery disconnect and GFCI breaker. 




This is the solar combiner box which contains a disconnect, fuses and lightning arrestor and employs an extension cord of the proper wire size for connection from the solar array to an inlet on the power system box to help keep the system as portable as possible.


This is a 24 volt system but your system could be configured in 12v or 48 volts also.  These batteries are deep cycle, solar/renewable specific 6v batteries that should easily have a 20 year or longer life if maintained properly.  The other components in this type of system are designed and expected to have up to a 30 year or longer life span.  You could also use sealed batteries if your unit will be used indoors as the escaping gasses from the unsealed batteries can be dangerous.  Working with any battery of this type can be quite dangerous so before you handle them be sure you know what you are doing.



Outlets were installed on the outside of the box for easy access and weather tight use while the box is closed.


A battery meter was installed inside the box to monitor the battery status and provide other valuable information.  

If you would like more information on how to build this system please feel free to send me a message and I can help you out.
