Building a small starter solar system

Hi, I am building a small solar system for my minivan and wanted to share my experience here as I build it. So far I have ordered a 150w solar panel and Battery.
(A charge controller is next. I suppose some wires (not sure of size yet) and fuses and small fuse-block may be needed.)

** Solar Planel **
A 150-watt solar panel, (Dokio, price $134, dimension 38x38.1/2 inch, 22 lbs, DSP-150w, high-efficiency Monocrystalline). ordered on amazon.

** Battery **
30Ah LiFePO4 Lithium Iron Phosphate

** Charge Controller **
Renogy Wanderer 10 Amp 12V/24V PWM Negative Ground Solar Charge Controller Regulator Compatible with Bluetooth Module
(It was the only cheap $20 PWM I could find for Lithium battery charging. I wanted an MPPT but could not find for as low as $20 with Lithium support.
I will order it tomorrow 5/16/20 sat if I can't find an MPPT for +/- $20 for Lithium.)

** Initial usage plan is for the following **
* small inverter 150 watts or more
* small fan or two (hopefully DC volts)
* 11" laptop (120v ac adaptor, 21-watt), though I might use my 15" laptop (120v ac adaptor 90-watt on occasion).
* Android galaxy s10+ phone, and other devices

I regularly visit the park every day. Rain or sunshine, though sunshine is better. I walk 2 for 5 miles at the park and then I read for an hour or so in the van. I am planning on spending more time at the park and with the solar setup I hope to be able to do some of the things I do regularly at home which is, being on my laptop mostly. So I want to have power for that, plus some fans if necessary.

I will definitely be making improvements once I get a better handle of usage.. larger battery, etc.

** Charge Controller ** I purchased the Renogy Wonderer PG

It was tough deciding what and which to go with. There were so many on amazon and ebay. But the main problem I had with most of them was that they did not specify support for the Lithium battery. The cost was the next deciding factor. I didn't want to spend more than $20 dollars but I was willing to go as high as $30 if it had all the features I wanted such as (a good readout display, mppt, lithium support), etc.. So, in the final roundup, I found five choices of controllers and I spent a good amount of time pondering over them:

As you can tell, I went with the Renogy because of popularity and price and features and it does have a good user-feedback display, however, it is a PWM version but it was in my immediate budget at this time.

I am considering the MPT-7210A as a possible future upgrade.

This is a fake MPPT that is really a PWM.
You dont get real MPPT for that low price.
I did not look at your other choices.
Saving a few dollars on a SCC is probably false economy.

Whilst I commend anyone to build their own DIY solar system, I'm not convinced this is the best solution for your usage scenario. If you did want to go the inverter route then then buying a small 'solar generator' device would likely be cheaper and more convenient. Will has done loads of comparison videos on these e.g. Renogy, Jackery, Goal Zero, Bluetti etc.

If you just want to extend your stay outdoors, have you considered a simple consumer battery bank? I use the 288Wh Ridge Monkey Power Vault to:

1. Charge my drone batteries via the 12V auxiliary socket
2. Charge my laptop via the USBC PD port
3. Charge my phone via the USB QC port

If your laptop doesn't have USB-C PD charging, then it will undoubtedly have a car adapter. Most laptops have a circa 50Wh battery so such a device could re-charge/power them 5-times over. Most smartphones have a 12Wh battery, so could be charged/powered 24 times over.

Or if you did want solar, consider something like the Goal Zero Sherpa units that can accept a solar panel input and power your laptop directly from it.

I'm not suggesting that you buy these products, I'm just saying that going DC-AC-DC isn't the most efficient route to run your laptop.
