OK ... So I waited until this issue was fully resolved to give me thoughts. And now it is ... Most People do not share their success stories, so I wanted to give a thumbs up to Signature Solar for this resolution We purchased a Growatt 12kW SPF 12000T DVM MPV 250voc from Signature Solar...

Up until Last week I had never heard of pre-charging a larger inverter before connecting the battery cables. I just lived with the spark. But I was watching a "Will" video about a DIY LFP build and saw that he used a resistor before connecting the Positive Terminal. This peaked my...

Installing The Big Growatt SPF 12000T 12kw Inverter into a Cargo Trailer for a 12k watt mobile power generator. All the panels will be installed on a pole/post barn and I will connect the Inverter's Solar Charge Controller MPPT to the panels via 8 awg SOOW cable and Anderson Connectors. First...

Here was my very simple wiring diagram for ordering parts and getting it all in my head

Today was cleaning, feeding and care day in the hydro garden . Got everything dressed up for beauty shots. This little hydro system keeps the wife and I in salad and greens 3-6 days a week. All we want. I harvested 3 stuffed grocery bags off it Monday ... Cut all these lettuces to nubs, and...

Friend's don't let friends buy AGMs

I thinks 2, maybe 7 ? Let's not spoil my chances with technicalities

That was / is the plan with the setup we built. Hurricane coming? Just get the batteries charged and pull the trailer to where the power went out.

Thist just in June / July power bill 2022. $245 / 1860kWh - day time indoor temp 78F June / July power bill 2023. $109 / 850kWh. - day time indoor temp 73F

Dear God, how did pioneers ever survive.

@Will Prowse ,I'm not trying to suck up or be a fan boy but I pretty much discovered the "how to" of DIY LFP from your videos. I've wanted to DIY LFP for the past 4 years. But finding a working bms and cost friendly cells made this out of reach. This forum solved both questions. And I've...

I'm on the way to Kissimmee. Tours of my set up are $5. The parks 1.5 hrs south of here are 20+x's that. I'm offering greater value. And lake front views.

Is that some kind of Magic Dryer? ? Mine uses 5000 watts an hour. That's the only thing left on grid. I'll use a clothes line in a $HTF

I think it's too hard to keep up with who is reputable. Many times a seller will start off reputable and sell a bunch of really good cells and then later on start dumping a bunch of bad cells

I do not understand the onion at all ... but this is my favorite Ohm's Law pic. I like the characters ?

THREAD INDEX: (Links Updated: 2/15/2024) This is a long Thread, So I have added this Index Note: Click the Post Number to Follow the link. The Topic discussion will follow from that Post TOOLS USED FOR DIY A/C INSTALLS Tools - 662 THE INSTALL General 1st 24k - 5 2nd 24k - 6 12k - 139 Nitrogen...

OK ... so on to the install. So far, I have the two 24k head units and condenser units installed. Communication lines and drains are coming together. First I did the Living Room 24k unit And outside ... a wall rack rated for 350 lbs. (NOTE: I also added a 3rd piece of UniStrut to...

Alright ... here it is. Ahead of Schedule. But I was in too much of a hurry to get it up before work tonight to shot video. So no video of the build and install. I think it came out pretty nice Concealing the Lineset and thru hole But the Wife is pretty much saying "NO !" on the...

And here I was just worrying the other day about where I'd dispose of these 40 cells I the have. If the OPs study is correct, I'll be dead, it'll be somebody else's problem ?

Energizer Lithium is the longest lasting. Says so right on the package.

Fucks or Ducks? I guessed it doesn't matter. Either way it's Fowl language. ?

I had a few little extra pieces of shrink wrap so I decided to wrap the tools that I commonly use around the Lifepo4 cells and terminals. Large heat shrink on the sockets A piece of heat shrink on the metal section of the torque driver And a composite ratchet round out my safety pieces I used...

Thanks. I now have tracking numbers and my cells are slated to arrive tomorrow. I might start my own thread of the unboxing and first impressions.

Summer Power Use Update since Solar AC install

Got the trailer for the Build at my house a few weeks ago. Have had some time to get things started. Batteries are Almost Done - They're mounted in shelves I built into the trailer - I built room for 5 battery banks, but we are starting with 2 - Got all the battery electronics in, and 1 out...

Yes no heat on the breakers, on the back wall, on the steel box. Everything is ambient temperature

Nor am I. Thank for the response. I will say, @Amy Zheng has been following up with me and she has helped me confirm the vendor from the QR code. I have been very impressed with her responsiveness. As was noted in the other thread about Doncan Tech, I hope they stay this way and keep...

The 2nd 24k install is more completely installed than the first, All electrical connections at the unit are done. AC power is connected. PV MC cable is pulled up into the attic waiting on the Solar Panel and Breaker Disconnects to be installed. The outside disconnect has a 20amp DP AC...

My PoCo bill has gone from $300 a month to $300 a summer

Same ... My Experience Here

I do not completely agree with this ... Let me read both good and bad and then decide. But also do not gloss over the bad or hide them all together. (not saying SS or anyone else does this). But in the end, I just like to make an informed decision. Sometimes I read the stuff people...

So glad it worked out for you. I know that Michael never had any intention for any of this

Been working on it and planning it for a while. And it just so happened to work out that the day I actually finished the job was also my Birthday ... today ? I have a single Midnite Solar Classic 150. For the past four years it has been just fine with a MS Classic Sizing Tool sized array...

I get that. I truly do.

Thank Goodness for Quad Breakers. I added two 15/20db/15s and one 15/40db/15. This gave me plenty of space for both the 24s and the 15k AND gave me one extra space I did not have. (Note: the EG4s are not wired yet)

A watts meter will not be fast enough to to pick up motor surge. It's measured in milliseconds. You need a good digital volt meter with In-Rush function.

That’s kinda how my POCO looks at it. I back feed once about 200 watts total (not per hour) for 2 days One weekend. My Schneider SW4024 didn't like being in AC Support mode and Load Shaving mode at the same time. Every time the microwave surged on it back fed the grid for a few watts. The...

BTW ... How to get free shipping on your SanTan order. 1. Order enough extra to cover the cost of shipping. ie. If you need 10, get 1 or 2 extra for you and then 5-10 more to sell 2. Sell the extra locally for local Pic up. on Craig list or Facebook marketplace 3. Figure in enough on the...

I'll take 95% and my potion can be kool-aid.

Well there's Ur problem right there. The battery voltage is falling through the floor and not recovering. It has absolutely NOTHING to do with Ur XW or firmware or that u need to use a resistor. That said, just watched @Will Prowse quick tear down of that battery he released today. After...

And it seems to me, sometimes they are politicized to discourage DIY, control the masses and protect the profits of a manufacture or Trade organization.
