DIY Portable Solar Power Generator Part 1
About | Information | History | Online | Facts | Discovery
This DIY 110 amp hour portable generator is designed to be powered by a 100W solar panel and 2 55AH AGM sealed batteries. The system includes a 30A PWM solar charge controller and a 400W pure sine wave inverter. 12V, 12V USB, and 110V AC outlets offer flexibility for powering/charging a variety of appliances. The system is also set up to be trickle charged via a SAE 2-pin port that allows for a convenient connection to an AC float charger. Total cost of all materials required to build this project, including all components of the generator and the solar panel, was approximately $950 USD.

Looks great! One small suggestion would be not to cross the battery link cables. If they were ever exposed to lots of vibration there is a tiny possibility that they'd rub against each other and wear the insulation down, eventually shorting out. Better to keep them separate on each side of the housing.

what would be your suggestion on boosting up the amperage? nice video btw

Im using 12v 50w solar panel with 12v 9ah lead acid battery and 150w inverter . it powers my very very old house . thx for inspiration !!!

How much would it be if I had you build one of these for me. I heard you mention you had $950 in raw materials. How much for your labor plus freight to MN. They look factory. This is one of cleanest DIY projects I have seen in quite some time. I just don't have the electrical knowledge to do it safely. I found something simular in Australia but they don't ship to US. You need to start building these for resale. Another question I have is what can you run off of these. I realize they can't handle things like a/c or microwave but just really need for lights, computer that sort of thing. Please let me know. I think you are fantastic in your knowledge, intuitiveness, and your explanation of the case.

Very nice build, I'm impressed. And the cost isn't bad for what you've built. I wonder if you could do the same build ony you these batteries. http://www.lithiumion-batteries.com/products/12-volt-lithium-ion-batteries/
Yes they are very expensive but they are also the best you can have for the long haul.
It seems as though the Smart battery Lithium Ion batteries could be used instead of the typical AGM batteries, of course you have to use the appropriate charger.
LOL, It would be a little more expensive though since two 12 volt 50AH batteries would cost about $1,378.00
According to their website "The SB50 is plug and play for any application that currently uses a lead acid, gel or AGM battery"
That's very interesting. -

WOW!
This is awesome and good job -
Hi Jim, very impressive and professional. Your work has convinced me that I do not need to purchase one of those expensive commercial units on the market! Thank you for sharing. Could you please explain your process to determine the battery and solar panel capacity? Did you create a power budget spreadsheet?
I am looking to create a solution like this to power my 12v astrophotography equipment over a 4 day period where there is no AC. Even though I do not necessarily need AC, it might be a good idea to put in an inverter just in case I needed it or wanted to use this solution for another purpose. I'd like to minimize weight as I have to take this rig in and out of an SUV by myself. However, I do need enough battery power for a complete night + some day time observing. I also need to plan enough solar panel wattage to recharge in less than a day + have some panel + battery Ahr buffer to cover extra usage and/or party cloudy day. I am trying to resist the urge to just buy (2) 100 Ahr AGM batteries and want to properly design this for efficient portability! Thanks -
wowww dude!!! you should make another couple of these and sell them!! I´d buy one from you without any kind of doubt!!! this would be useful as hell for me!!!

Hi dear can u guide me how to make booster jump starter with lithium 3.7 batteries
-
AWESOME!!!!
-
You could totally start a small company building these things. There is a pretty large market for something like this, even on a global level!
-
Very neat and tidy. Impressive!
-
For that size and for your purpose, I'd probably use epoxy encapsulated charge controller and inverter from morningstar if you ever have it to do over again. No moving parts and very moisture resistant. I hate to use the words waterproof, but they are pretty close to it. no moving parts but the inverter is a little $$$
-
Great job. Very professional. Thanks for posting.
-
Awesome!
-
Clean work. I'm a electrician and see such sloppy work everyday (service tech). Good to see one guy every blue moon doing it clean.
-
As a mechanic I've seen nothing but trouble with those scotch locks!!! They seem to attract corrosion!!! Loose them and splice and solder them with shrink tube and you just can't go wrong. Otherwise awesome piece of equipment there!! Great job!!
