Fedex claimed to of delivered my package Friday to my backdoor, which is nearly impossible. Today they said the driver is coming to my house to "figure out where he left it." - In the 15 years I've lived here, not a single soul on this planet has ever trespassed in my back yard. Not even...

I've been running my main system with 2 panels per string for a couple years now. One thing we learn as we're building a system in series vs parallel is that in-series has a bigger negative impact from shading. But, today is the first time I discovered how big the impact was as I received a...

Can someone give me tips on sizing an array for 1 unit? I'll have up to 13' x 13' of surface available for the panels. The distance between the SCC and panels will be 40-80' depending on how close I put it to the main breaker panel. I have plenty of 10 AWG solar cable, but will buy other...

These are new (never used) despite being from 2014. Considering 2S4P. Datasheet (pdf) und

Anyone know the program running this forum? It is the best Forum UI I've seen. I love it. I see all URLs go through index.php. But can't find a reference to the project. @Will Prowse ?

Am I missing something? The packing is clearly labeled "with cover". But I don't see a cover in there and don't want to open it in case I need to return it. Am I blind? Here is the item.

Something is breaking when I post something, so testing it here.

I'm leaning towards the LV2424 for 2kw array in USA. The primary feature I love about it that I cannot find anywhere else is its ability to switch to grid for AC input when their isn't enough battery or PV for the load. Can someone recommend an alternative solution that meets that requirement...

EDIT: Appears to be a different link than what was in the youtube notification email I loved it! Man, I hope it's cheap cuz that is an awesome unit. @Will Prowse The emailed notification link was not public. ;) Emailed link: gVoJTBIglgU

A friend just sent me this pict. I don't think it's a portable solar box, but look carefully. The WHEELS!!!! LOL! This should definitely be a portable solar container if it isn't: @Bob142

Can someone link to a good bus bar for 4/0 to 4 AWG range? I noticed the current flow through my bank is not ideal, and suspect it is because of the FUSE I put on one of the positive terminals where I then connect the inverter. The side that is not connected to this is not draining nearly as...

I've seen @Will Prowse recommended TEMCo (ebay) for solar cable, and AC/DC recommended for battery cable and lugs. Does anyone want to yay or nay them or recommend others? How would you rate how well they connect the lugs and experiences with heat after? (I do plan to take all the great...

We have 12V sockets and 120V receptacles and may others. But, what would be a standard 24V socket or receptacle? I'd like to plug in stuff to my 24V battery bank without converting to obtain maximum efficiency. I know you can buy lights and fridges that work with 24V. Any other ideas on...

This splurge started when I bought another 10,000 mAh power bank, than a 20,000 one, than a 63,000 one (which I love, but that deserves another thread), all to power a laptop all day outside. I just couldn't stop. Then I saw the refurbished Bluetti AC200P being sold by Bluetti itself, with...

I can find them on ebay rated up to 30VDC. But, I'm concerned that doesn't cover the high end of the voltage. I like the MPs, but am open to another maker if someone wants to recommend. This is standalone, so needs its own housing. If someone can find a higher V rating with this quality for...

I just discovered this free resource: https://www.solarprofessional.com Has PDF versions of the magazine online. Has anyone been reading it and developed opinions on it?

Looks like vapors want more energy storage than just the 18650s now...

Can we generalize some topics because there are things that transcend multiple categories and thus are hard to find the right home for. So, for instance, a General DIY Battery category. To give an example, I'd like to begin a thread on dealing with issues of cells or batteries in parallel...

I have a flashlight you shake to power it. It uses magnetivity to generate DC, which I believe it stores in a capacitor. I can share a pict if someone would like it. My dog runs all day long. Burns a ton of calories. I'd like a light on his collar that charged during the day, then lit up...

Some have said and read that you should shut down the PV before disconnecting the battery from the SCC. I was wondering, if you shut down the PV before applying a blow torch to the SCC, will it still melt?

Get a $15 box fan from Walmart and plug it into a 120V outlet. .

I have a 2S2P Lion Energy 1200 bank. The positive and negative are connected at opposite corners to ensure the juice flows evenly across all 4 batteries. However, the ones with the external connections (circled with yellow below) drain to 0%, while the others are still holding 80%. Why don't...

I plan to put 4 of these Lion Energy UT 1200s (photo below) together for a 2P2S 24V bank. How would you configure charge rates and size battery cables and fuses for peak discharge rates? My assumption would be to double everything so - discharge rate: 300A max continuous (2P) - charge rate...
