Plan to use a large van or RV
Plan to run most appliances, such as a computer, microwave, fridge and more

Recommended components:

400 watts of solar panels and a 40 amp MPPT charge controller
300 amp hour lead acid deep cycle battery bank (or 200 amp hour lithium battery)
1100-2000 watt inverter

Estimated Cost of Components:

$500-$600 for Solar Panels
$200 for Solar Charge Controller
$700 for Lead Acid Batteries or $1029 for Lithium Batteries

400 watt Solar System Blueprint

Warning: Please read my book for full installation instructions and safety considerations!!

Step 1: Mount components to a wooden board like this:

This picture should give you a rough idea of how to mount and connect your components. Each system is different though, so be sure to use my book to calculate the fuse and wire gauge size for your components. This picture does not cover other remote wires/shunts/temperature compensation wires etc, so please be sure to use my book to understand how this all works!

Step 2: Connect the Battery Bank

If everything is installed correctly, the solar charge controller should now turn on, and you should be able to run the inverter. You may see a small spark when you connect the inverter to a battery, and this is completely normal.

Step 3: Mount Solar Panels to the roof and Connect them to Solar Charge Controller

If you follow the previous steps correctly, the solar charge controller should now be charging your battery! (if there is sunshine present)

What Components I recommend for this system:

Buy 400 watts of glass solar panels and a 40A MPPT:

4 * 100W Monocrystalline Panels

high-quality cells
high conversion efficiency
thunderstorm and moisture
aluminum alloy frame
