Thank you for sharing this. Great job 👍

Thank you !

No smoke is away good

[@OurBlackCatCottage]

LOL. So true

[@keithshumaker6402]

You want the batteries hooked up first so power has some where to go when you put the panels on

[@OurBlackCatCottage]

Solar panels were attached last.

[@keithshumaker6402]

I would have put 2x4 in the corners to make it more durable

[@OurBlackCatCottage]

I did think about that but it is not needed. I have built several of these and the 3/4 plywood is enough. Once I made one from 7/16 and it was way too weak and could have used corner supports.

Could you please tell us where you got your Batteries from and where you got your buss bars at please and thank you much appreciated

[@OurBlackCatCottage]

This battery was an old one I DIY years ago. I would recommend OKMO batteries - amzn.to/4euRDWn And the busbars are Blue Sea Systems - amzn.to/4ixTWv4

200 AH? Or 100AH battery? Also, did I miss the BMS on your diy battery? I'm no expert. Seems like just one fan, for exhaust, would work with a static vent on the opposite side of the box.

[@OurBlackCatCottage]

It is a 200ah battery. 100a JBD BMS. Can't really see it from where the camera is. In my first builds I tried just one fan with vents on the opposite side but it wasn't enough air flow and the inverter kept getting too hot. Two fans just works better for me.

[@cruikshank]

@@OurBlackCatCottagecan you explain to a newbie why you would use a 100ah BMS with a 200ah battery? Thank you.

Too bad you used a cheap high frequency, output transformerless inverter in your design. A low frequency, transformer based inverter would have made a much better choice.

[@Scott-ig1zd]

That would increase the weight and cost x2. Plus he's comparing it to a ecoflow delta which has a high frequency inverter.

[@OurBlackCatCottage]

I disagree for several reasons. As others have stated, it would be much heavier (and more expensive). I have used low frequency ones on builds and they don't work because of their weight and size. Second, that inverter is an excellent inverter that I have used for years and works great. I have several low frequency inverters and they are superior to high frequency ones in many ways but are not a good fit for small portable power stations.
