Build A Solar Ammo Can Full-Length Instructional Video

[@BenjaminNelsonX]

Hi folks! Due to popular demand, I have made laser-cut wood faceplates available for sale. Please visit 300mpg.org/shop/

[@Pa11en]

Perhaps we could have made a faceplate, but I really loved your idea of internal connections and found your video and 'Instructables/Ammo Can Solar Power Supply' directions useful to My wife and I making an "A.mateur M.obile P.ower Box" togather. Purchasing your faceplate gave us a prefect way to both thank you, and not to have to make our own plate.

[@erickruepong9105]

Is possible to just buy the whole system?

[@BenjaminNelsonX]

@@erickruepong9105 This was designed as a way to teach people how to build their own project and learn about solar and battery basics by doing so. If you simply want to purchase a battery backup device, there are many of them commercially available. For example: amzn.to/3xxyO2X

[@douglaswindsor120]

@@erickruepong9105 Eric if you watch the free adds and garage sales you can quite often find booster packs with modified sine wave inverter and some with an air pump as we'll all you have to do is replace the battery you can get USB ports most have battery level indicator but you need to add a set of terminals to hook a good battery charger to charge it up the charger that comes with them is designed to kill the battery in about a year so they hope you'll buy a new one I did that for over 40 years since I'm a horder I've still got a lot of my old units since I've found utube I've found out I can put a new battery in a couple of my bigger and better units so that's an idea also if you want a good cheap unit just buy a booster pack with a modified sine wave inverter most now come with USB ports just don't trust the charger that comes with it get a good battery charger and either charge through the booster cables or the auxiliary plug for solar charging harbor freight has a 100 watt solar panel kit that includes a controller and lights that plug into the solar charge controller with USB ports since non of the reviews I've seen tell I'f it's got proper charging parameters for sealed lead acid batteries but for around 200$ you can get a full system the booster packs are usually under a hundred dollars most of mine cost less than 60 dollars and I'm told the harbor freight solar panel kit is around a hundred dollars if you have devices that need USB quick charge and type C a unit that plugs into the auxiliary plug is around 10 dollars and the type C is around 30 $ you can buy splters that take the auxiliary plug and split it to 2 or as many as 5 auxiliary plugs the nice thing about the USB adapter is you can use them in your automobile to charge cell phones fit bit watches and laptops most people already have at least a slow USB adapter for their phones but the newer phones that take type C charge way to slow on them I plugged my phone in to the USB port in my sister's car for 3 hours and got a whole half hour of run time had a 2 hour trip and it died before I got a half hour out i Now have charger in both my vehicles so that won't happen again also my fit bit watch wouldn't charge on the slow charger it needed quick charge and wouldn't plug into type C

[@BenjaminNelsonX]

Nice job! Keep up the good work!

[@BlessedLaymanNC]

I've seen this video three or four times over a number of months. This past week, I accumulated all the major components for mine, but when I started to get the little things I need to put it together, I discovered they were nickle and diming me to poverty! I originally desired to fuse and switch everything. You reminded me to KISS it! I originally started to fuse and switch just about everything. Yours uses only one switch and one fuse. I decided to change mine to use only the one fuse, but two switches. First of all, I follow the growing trend not to use the "load" option on the solar charge controller (SCC). I use mine for ham radio transmitters and on three different SCCs the "load" can't handle even the smallest radio, way below the rated current. Instead, my output devices will connect directly to the battery (always to the master fuse.) One switch will go to the SCC so I can turn it off when not charging the battery. The other switch will go to the "accessories", just as your accessory panel has. Like yours, the input and output ports bypass the switches and go directly to the fuse. I'm designing two of them and am actively assembling my prototype. My prototype will be using a 16Ah LiFePO4 battery, and have three separate 12v-USB charging ports and two APP ports. The 12v-USB ports with multiple outlets never charge two devices as fast as one. So, I'm installing three so everyone in the family can fast charge one of their devices at the same time. This is the primary purpose of the prototype, but it will also double as a power supply for picnic-type ham radio portable outings where I operate a few hours and come home. It's not worth setting up solar for one or two hours and the battery powers the radio for 5 hours. With the kinks ironed out of the prototype, I'll build four more with 32Ah LiFePO4 batteries with the same power panel as yours, but with APP where you have banana jacks. One of them will have a pure sine wave inverter for my CPAP and the others will be equipped with inverters like you have. Each family member gets one during a power outage and I get one for the CPAP and one for the radio station. The prototype will still be there for charging phones and tablets as needed.

[@ttvnlrider]

You should switch the red fused wire between the battery and the solar charge controller. Save from a parasitic draw on the battery. Nice build clean looking.

[@jimmywalker2429]

I know it's a few years old but I've built my 3rd box since I saw this a couple of years ago. I did modify it a bit. Used 2 batteries, a solar controller and a 400 watt inverter with discharge control. Both batteries fit perfectly. The controller is mounted but the inverter is loose. It would run our lights, TV and 18v battery charger. Good stuff. Thanks for this video

How much did you spend on it altogether?

[@adamasalawan971]

​@@SJ-xg1uf I spent about $130 USD on parts. As of the time of this message, my generator was stolen. However, if I did it again, it would be cheaper. Get this: the Yeti 150 by GoalZero is about $300, but this thing is more powerful.

[@mschaus]

Nicely done. Note that the wall wart charger does not have a constant-current mode so is not really appropriate for battery charging. In the video, it is trying to charge, seeing effectively a short circuit, shutting down, and then starting again. One solution is to add a buck converter with an adjustable constant current setting between any power supply and the battery. Old laptop power supplies are great for that if you want high power (with an appropriate buck converter).

[@edmendlha]

You've done a great video explaining from the beginning till the end of the Solar Ammo Can. Not to forget it is not a solar generator. ;)

You are awesome. I got a 100 ah battery with a ice chest. That idea is perfect for my project. I have the same whistle you have . Only difference I'm adding 1000 walt inverter . Thanks for your knowledge and ideas. You are awesome

[@mikem2736]

If all you are going to run is an ice chest then you might want o measure just how much it draws. If all you need is 100w then a 100w inverter has a lot less conversion losses than a 1000 watt inverter. As an example my 300w inverter with no load draws 1/4 of what my friends 1000 watt inverter draws with no load.

[@toddbatescreative4703]

Just assembled mine last night and realized two things: you can't run an inverter in the cigarette lighter socket (the solar controller instructions says you can't do this, when I tried it would shut everything down), so I rewired that socket directly to the battery. I ordered a Low Voltage Protector Disconnect Switch to add to that circuit so I don't drain the battery. I've also decided there's plenty of room in the box for another battery, so I've ordered another one and will run them in parallel (as per the solar controller instructions). I'm adding a second solar panel as well. Other than those issues/mods, it works perfect. Thanks so much for the video!

A really good tutorial for starters, like the way you did the wiring. Most have a big mess which you should avoid. Seems a rather good battery for its size, as I watch I noticed you could add another one easily. 30Ah total is probably overkill but with an inverter, you could run that fridge an hour longer if needed. Having a few accessories on the lid itself is basically a choice. I do find that impressive and will stimulate you to use it more. Thanks, I changed a few plans myself because of this.

[@W8MJL]

Is there at least a 15 amp fuse on the socket? Or maybe the capacitor in the inverter is pulling too much current when initially plugged in.

Hi Steve! Thanks. One of the reasons why I planned this out was because of a number of long-distance canoe/camping trips I've gone on with my Dad and my brothers. My NOT modifying the Ammo Can case, it's totally water-proof. I would often toss my cell-phone inside it to charge and have the cover latched.

The objective is to power my greenhouse with a solar panel, and for those "raining days" with not enough sun light, the charger would keep the battery always charged?

How much power does the solar charge controller draw as a parasitic drain? This will eventually run the battery down sitting on a shelf. It should also be switched.

[@mraleksk1]

That is exactly what I thought. Lots of guys who doing Ammo can like that missing that velcro could solve lots of their issues. I was thinking to use velcro to hold all the stuff. That is the way to go! You as well could add a little car Ham radio in it...=D In that case, I would put the battery in the corner instead of the center, farther away from the radio, and add an antenna connector(s) on the top. Plural or singular depends on if you have just a 2 band radio or quad band radio...
