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 that is aerodynamic
- Plan to run a laptop, USB charger, and some LED lights (but do not plan to run any large motors/microwaves or large appliances)
- 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
- $130-$260 for Solar Panels
- $125 for Solar Charge Controller
- $280 for Lead Acid Batteries or $950 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)
- Complete System with Lead Acid Batteries: $1075.00
- Complete System with Lithium Batteries: $1,745.00
(Lithium is still cheaper option because it will last 4-8 times longer than the lead acid system)

What I recommend
(I Make A Commission For Purchases Made Through The Links Below)
Buy this battery:
|
The SOK 100 amp hour Lithium Iron Phosphate Battery.
This battery will last 3,000 to 5,000+ cycles. It is small and light weight. This battery is much cheaper than a lead acid battery, if you take its longevity into account. 100Ah SOK Battery Click Here 206Ah SOK Battery Click Here Click here for more lithium battery options |
If you plan to use your system for less than 3 years, and weight is not an issue, you can buy this battery instead:
|
100 amp hour AGM Sealed Lead Acid Battery

Choose a Solar Charge Controller:
If you are on a budget, a cheap PWM controller will work... but I highly recommend buying an MPPT charge controller. The increased efficiency of an MPPT charge controller makes it worth the money. The MPPT will take care of your batteries better in the long run (it has temperature compensation and other battery maintenance features). The MPPT controller below will also let you know how much power your solar panels is producing (if you buy the MT-50 with it). There are more reasons that I could list, but buying a MPPT is a no-brainer. Spend the extra money and buy it (unless you absolutely cannot afford to do so).
MPPT Charge Controller (recommended)
|
Max. Solar Input Power:
260 watts of solar panels This charger has over-current protection which means that the figures above can be doubled! 20 amp MPPT charge controller (98% efficiency) Click Here Recommended MPPT Accessories: Temperature Compensation Module (click here) MT-50 Control Display and Interface (click here) |
PWM Controller
|
It will charge your batteries and it is cheap, but I do not recommend using it unless you are on an extremely tight budget.

Buy This 1000 watt pure sine wave inverter:
|
Really great inverter! Pure sine wave is ideal, and this inverter will last for years (I am still using one I bought ages ago).

Wiring products:
|
High-Quality Copper Wire for DC appliance hookup
(most wire on amazon is "copper clad aluminum", which is cheaper but lower in quality): 50 feet 10 gauge Blue/Black Click Here |
|
|
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. Click Here |
Fuses Required for this system:
|
|
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:
|
Required for all systems. Tells you voltage of the battery and amp draw. Simply attaches at the main negative lead of your battery bank.

Required Tools:
|
|
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 |
|
|
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. Click Here |
|
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: Click Here |
Accessories:
|
12 volt USB charge strip

|
|
46 Liter Dometic Solar Power Fridge
Click Here |
|
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.
