The (semi) final version. Semi, because I still have to get the cable grommets. One thing I'd do differently if I was starting again is...

I've had some quotes for bifacial panels on Alibaba and I have to say, the prices are much better than what is available locally here in...

Give it 2 years, once you know all it's quirks (the absolute worst is "I finished my part, let me just add a small hole in the first...

Not paying with a credit card for all my solar purchases on Aliexpress 🤣

Here is the layout that will be used. Cables will be tidied up and the BMS will be held to the top of the board by vhm tape. I'm not...

I would stick with 48V for any sort of home power just because it can scale up if/when desired more easily, and keeps current lower (and...

@SparkyJJO already said almost all I wanted to say :) However, one thing to add. Even if you decide to downsize your loads I'd...

If you're trying to run all that I wouldn't even think of anything less than 48V. For your inverter size you really need to look at...

What do you think about putting some polyurethane building foam around your battery pack if you're using a toolbox for a case and you...

You must be in denial then. Have you been perhaps bamboozled by a seller of such cells? Why else would you just skip over everything...

Very funny. Do you by any chance sell these swollen cells too?

Yes, this is correct. I wonder what alloy these are. Probably 1xxx for electrical conductivity, but it is one of the softest (pure...

This is so wrong when we're talking about 7~8 year old cells that measure slightly half of their rated capacity and an internal DC...

Yes, I'm rather dissapointed by this. I'd much prefer this was a screw terminal. I believe the usual mode of failure for soldered...

Thanks for your reply. I agree these are fine to swell during use, but not when new and unused. Swelling is in a way a proof they are...

Seriously? They are soldered in? Can you post a picture please? One buys these black ones as a supposedly premium product and they have...

This is actually good, because it lets you put all your critical loads on one phase if you wanted. A single phase system is much...

I think your cells are going to be fine If they test over or very close to rated capacity at 0.2c (20A in your case). What voltage pack...

Hi, These rules read very similarly to the rules we have in Poland, except the "Over 6kw, a govt. inspection is required every few...
