HI. I have a similar setup – 3000w inverter is driving one portable AC unit around 5-6 hrs/day (timer based) – trying to keep a balance while charging batteries 6-9 am and 4-8 pm which is helping to reduce a tremendous summer electricity bill in UAE. Four 400w panels, and 4wheel trolley for batteries and inverter in use when I need to move it anywhere.
This had me interested until the end where I see the price for this setup. Way, way to expensive. Didn't think solar was that expensive. Good video though.

Have you found an easy way to limit charging the battery to 80%? I tried contacting Signature Solar, but they never responded to my email about it. Thanks in advance.
You did not discuss islanding – if power goes out in your neighborhood and you plug your device into one of your outlets to run the house, you could end up supplying power to the grid. In effect, you could end up trying to keep your neighbor's refrigerator running. Also, if power line workers start working on the problem within your particular island, they could be exposed to mortal danger. As built, I recommend you ONLY plug appliances directly into the power strip and don't try to power up your house in the event of a power outage. I also agree with the grounding comments below. Don't make an ash of yourself, ground this sucker!
I would put the unistrust on the back side then use longer hardware to mount it. The weight would be in closer to the hand truck. I would also recommend putting it to use full time to offset the cost. Mount some solar panels and power as much of your house from it. The battery will fail due to years far earlier than you will wear it out for cycles plus you know it's always good to go if you're using it.
Thank you for making this video. I built this today. One thing you say in the video is that you'll "test the communications later." I was unable to find a video where you tested the communication though. I watched a Signature Solar video that showed how to make the connection. It would be helpful if you posted this link in the description of the video: https://youtu.be/v8szZq6STcw
Can someone please explain how you can use that Growatt inverter outside? It is rated for a relative humidity of 5% – 95% noncondensing. I live in Florida and the humidity is perpetually 95% or higher.
this is not building u just bought ready stuff and bolted to a trolley… 0 electronical value wasted time video for idiots how to bolt a freakin box to a cart

This is a super quick and easy build. Let me know what you guys think!

I like the concept of the mobility. What about the solar panel system: how many panels and specifications to charge the battery?

Great vid π
I used it for a week and it works amazing
Great video, would be awesome to see more info on the performance and capabilities. How dust friendly is this? Iβm wondering about a camping rigβ¦.
Should this be hooked up to 3 -400 watt panels?

The switching of the solar inputs confused me…Is there a video to explain this? or could someone explain this to me? Awesome video!!
What would
Be the best solar panel to hook up to this for quick charging?

Title says 'portable solar power station'. Where are the solar panels?

America has so many power outages
I love how clean and adjustable and reusable your setup is! Nothing is permanently joined with welding.
One adjustment for even cleaner setup. Use velcro stripes instead of tie-wraps.
Peace!
How would you configure this to be a everynight or backup charger for a Tesla 3?
3000W metal cart, I hope you ware thick rubber gloves and boots when moving this. you should call it the DEATH CART….

Nice awesome concept power pack Nice concept battery concept
Good video I thought based on the economy the more something came into production the cheaper it was supposed to be this stuff is insane
this is not building u just bought ready stuff and bolted to a trolley… 0 electronical value wasted time video for idiots how to bolt a freakin box to a cart
do you build and sell it? thank you
