The Minimalist Solar Package

This setup works well if you:
  • Plan to install in a minivan/car/off-road truck/cargo van with limited roof space
  • Want a lightweight setup
  • Plan to run a laptop, USB charger, and some LED lights (but do not plan to run any large motors/microwaves or large appliances)
Recommended components:
  • 100 amp hour usable deep cycle battery
  • 100-200 watt solar panel 
  • 20 amp MPPT charge controller (PWM controller if on a tight budget)
  • 750 watt inverter
Estimated Cost of Recommended Components:
  • ​$130-$260 for Solar Panels
  • $125 for Solar Charge Controller
  • $190 for Lithium Batteries
  • $170 for Inverter
  • $140 for Branch Connectors/Cable Entry Gland/Wire/Crimp Connectors/Fuses
  • $50-$150 for Tools (Cheap tools are available, but you are better off buying high quality tools)
Estimated Total Cost with 200 watt solar panel array:
  • Complete System with Lithium Batteries: $855!​

What I recommend
​(I Make A Commission For Purchases Made Through The Links Below)

Buy this battery:

Picture
The Li Time 12V 100Ah Battery. Best bang for the buck lithium battery around!
  • Largest Surge Capacity in the market! When connected to a 12V inverter, it pulls as hard as a 5000W solar generator. This model in particular has a special BMS manufactured by Li Time to accomplish this. You can even run a 48V golf kart by putting them in series or trolling motor with a single battery!
  • Low Temperature Protection. Every other battery at this price point does not have low temperature cut off. This one does!
  • The build quality is better than any battery they have made to date. I have tested them all, and this one is the best. 
  • You can use 4X of these batteries in series to create a 5kWh 48V battery for $1,476! Which is the same price as a server rack battery (I would still go with server rack battery though)
  • And it is under $400. Pretty wild!

This battery will last 3,000 to 5,000+ cycles. It is small and light weight.

Buy 200 watt solar kit:

Picture
Doesn't get cheaper or easier than this! This kit is everything you need to charge a 12V battery with solar. 
  • 2X 100W Monocrystalline Panels
  • 1X 20A Lithium Specific MPPT w/ Bluetooth Communication
  • Solar panel extension wires w/ MC-4 and inline fuses
  • 2X Z-brackets for mounting your solar panels
  • Large fuse for the MPPT

Buy This 1000 watt inverter:

Really great inverter! I used this one for a few years without a single issue.

High-Quality Copper Wire for DC appliance hookup
(most wire on amazon is "copper clad aluminum", which is cheaper but lower in quality):

Solar Panel Cable Entry Gland

When your solar panel array wires enter your vehicle, you will need to drill two holes. Use this cover to prevent roof leaks from developing.

Fuses Required for this system:
Picture
Main 200 amp Bolt-on Battery Fuse

Put this directly on the positive terminal of your battery. This fuse works well with the recommended 1000 watt inverter for this package.

Fuse Block (connect 12 volt appliances here

​Connect solar charge controller here as well. If you are using the recommended 20 amp mppt mentioned earlier, attach it to a 25 amp fuse on this fuse block.

Solar Panel Mounts:

Every vehicle is different, so check out my book or this page (click here) to figure out how to mount your solar panels

Battery Monitor:

Picture
This device will tell you how much power you have left before your batteries go to zero. Simply attaches at the main negative lead of your battery bank.

If you want a higher quality battery monitor with bluetooth connectivity and data logging, check out the Victron Smart Shunt instead. It does cost more, but it is a fantastic device that I use on all of my systems: Click Here

Required Tools:

Picture
Precision Wire Stripper
​(recommended)


8-22 gauge wire
Click Here
Picture
Hammer Type Crimper
Can crimp up to 4/0 gauge wire, and it is much cheaper than other large wire crimpers. If you plan to build only one system, this is the tool for you. 

Click Here
Picture
Ratcheting Crimper
Allows you to crimp standard size crimp connectors. Does not work well on waterproof connectors.

Click Here
Picture
High quality manual force crimper
I use this crimper when I am dealing with a non-standard size connector. The long arms provide a lot of leverage and I can usually crimp anything under 8 gauge.

​Crimp Connector set
There are cheaper crimp connector sets available, but they are junk! Spend the extra money and buy a high quality set of connectors. The cheap chinese ones will fail and I have had it happen before. This is what I currently use:

When connecting fans or lights or pretty much anything, use these quick connectors that are rated to 60 amps! I have used them for years for my rc airplanes and helicopters, but they are insanely useful for living in a rv.

Super useful clippers. Use them to cut anything small.
