DIY Solar Generator! 1536Wh Portable Power Station Lithium LiFePO4 HOW TO

Cahn shows you how to make an easy DIY 12V solar generator / portable power station - check this out!

Inside is a 120Ah 1536Wh Lithium LiFePO4 battery, 25 Amp DC DC charger, 500W Pure Sine Wave Inverter and a Touch Pad Switch Panel so you can turn on all your accessories and power all your gear!​

With a solar input, alternator input, movement-activated ignition sense charging capability, pure sine wave inverter automated cooling fans and more it’s a serious bit of kit that offers seriously good value and is a great fun weekend project!

Whether you use it for camping, 4WDing, van life, overlanding fishing or just at home in the backyard you’ll find some many uses for a portable all in one 12V and 240V off grid power setup! We’ve used it to run a camping fridge, power camp lights with a cig plug or USB devices, charge a laptop or even run the 12V Adventure Oven. After all it's basically a portable dual battery system in a box!

It might not look as pretty as a Bluetti or an Ecoflow but this is a modular DIY design that you can always update or upgrade later on!

When you consider the charge cycles for some of the overlanding market's most popular power chargers this setup blows away the competition. The fact that it's serviceable, not limited to size and output is what I like the most. Thanks for sharing.

[rogerandlyndabeall]

A good effort. I have made heaps of these I have found minimum battery is 200Ah, and minimum inverter is 800w run 1600 watt peak pure sine. Then, you can run your fridge at home for 24h in a power failure, or your tv for 43 hours. Then it is really useful. I use a victron inverter/ charger, as it shuts down automatically when there is no load ( like when your fridge is cycled off) and sames standby current. I also used the victron inverter charger, as then it works as a UPS and charges the battery, from the mains. I also add an RCD and an earth spike so when camping and a mains appliance gets wet, it wont shock you.

Awesome build. Would definitely be keen to see a bigger version... more battery, 1500w invertor, 40a DCDC, Ciggy outlets, LEDs inside and outlets, maybe control panel in the lid... So many options. Loving these vids :)

Nice build mate well done! I did a similar build during my COVID lockdown in Melbourne. Using a 120Ah Lithium, 3000W inverter and DC to DC charger. It runs my coffee machines, portable induction hotplate and fridge no problem at all. I have even used it for my rotary hammer drill on the farm. As I have only got the 1 x 120Ah Lithium and want to use it for everything I've linked 2 portable solar panels to give it a charge capacity of around 12amps. I've also added a battery monitor that give me Amps in and out so I can see how much I'm using and how much the solar panels are putting back in, which has been very handy, when one of the solar panels wasn't charging. Keen to see how the bigger box goes as mine is heavy enough now! I am thinking of being able to just plug in, via a Anderson plug, another 120Ah lithium in parallel to give me more capacity. But at this stage I haven't run it near flat yet!

@7:36 realize he over cut the hole, improvises (nicely done), plays it off as a simple change of mind! That is exactly how DIY goes... If you don't make mistakes and then find ways around, then your not doing it yourself! Bravo!

[ARLGD]

Wow, this solar generator from Segway looks like a game-changer for outdoor enthusiasts like us! With its massive capacity, fast recharging, and waterproof design, it seems perfect for camping trips or even as a home backup power source. Definitely worth considering for anyone in need of reliable power on the go. Thanks for sharing this video!

That's slick. I think the only thing I would do differently would be to run the sense wire from the alternator back to the box instead of relying on the tilt switch. You can run it along with the power wire since they are both up in the engine compartment.

but man, that is about as clean a DIY portable LiFePo4 battery setup as you can get.

[Jlomb]

My dude, this is the cleanest box build I've seen and I've watched a lot of these videos. Fantastic job although I'm sure everyone has already told you so. Sadly, we don't have any boxes like these in the States and everyone ends up using these terribly lightweight tool boxes that would break if you sat on them. Love these!

[CJ-tfvq]

I’ve just finished making a setup incredibly similar to this, I’m reasonably handy but it took me 4 full days. I didn’t put in an inverter but did use the other kings dcdc charger and added a battery monitoring system. Just a heads up for anyone else wanting to do the same. A very good system none the less

[kiwited]

Love to see a 200 or 300 Ah version of this with bigger inverter. Also a component list to take to your store! would be a great help.

[RealeaD]

Just wow. If Kings sell ready made versions, that would be fantastic!

[Clrky]

This needs to be an off the shelf item, could finesse it a little more. A 1500w inverter would be unreal. Have it without the battery to keep costs down, also for those with existing batteries or for those who may want agm or lithium. I’d buy one in a heart beat

[muzzaball]

Jeez Cahn, you really are the King of DC power! That was a superb build and a fantastic multi function solution. Well done mate! Cheers.

[nelskiedafishing]

You guys should sell this ! It’s soo awesome so easy and neat looking definitely I will buy this set up 🙌🙏🏻 soo good

[Tunzbig]

Everyone rips on the gear but thanks for taking the time to make this video.

[awsuccessfulliving]

You guys should sell this as a complete kit. ITS A Guaranteed product winner. The other thing is to do a Masterclass VIDEO work shop of step by step wiring as a complimentary addition for those wishing to do a DIY.

[keithhellyer]

Wow, have been looking at making a new upgraded (from agm to lithium) 12v portable power unit for camping and the back of the 4wd and this is the best setup I've seen, thanks for the video.

[newageaz]

Thank you SO MUCH for this amazing how-to video. I was able to build one of my own (with my son's help). For the case, I used a rolling toolbox from Harbor Freight to make it more easily 'portable' when I need to move it around.

[Teddybearrodgers]

You need to make these and sell them for everyone 👌🏽

[carloscolmenares]

The motion sensor and fan are a great idea
