This system is a beast if you want to make your coffee in the morning and have multiple devices for your kids! It is somewhat portable on a roof rack on your car or RV also with a trolly you can transport it to or from your tent. It can handle a solar panel array up to 500 watts, also it can handle a large (up to ~250Ah) battery bank of 12v batteries and can power a large 12 volt Inverter.
*Watt is depending on solar panels and Inverter size will be limited to battery size.
*High watt Inverter will drain your battery fast depening on use so monitor and protect your batteries from depletion.
*Inverter check so AC and outlet is for your country.
(Watt=W, Amp=A, Ah=Amp-hour)
Picture on top showing version 1 (v1) of the box, it is a little small so I recommend a better larger (v2) below.
Estimated Cost of Components
~$1000-$1700.T he estimated cost is depending on if you already have some components like batterys (as I had for first build).
