I asked Will to create this subforum so we could discuss real world and theoretical issues that may not be code compliant and will probably violate manufacturers warranty. I also hope for spirited discussions without anybody getting hurt feelings. It's ok to disagree I hope to advance knowledge...

Just finished my new 5.5 kilo watt LTO pack. I've been contemplating this for over a year and finally put it all together. I custom built 12 4x11 bus bars and 1 2x20 bus bar Plus the terminals are 1x4x6 solid aluminum tapped to allow set screws to clamp cables in. Topped the cells with 1/2...

Seems to me like he was just experimenting and learning how things work. He was not connected to the house or the grid at all. Sorry excuse my anger but moronic code enforcement officers and crybaby rip off solar installers really piss me off.

So I spent the last week building this 2.4Kw ground mount array. Hopefully tomorrow the sun gods will smile and I can test it. I picked up 18 150 watt panels off of Craigslist for 350 bucks. The rack I built cost twice that but I think I am still way ahead at about $.44 per watt installed...

Here are a few photos for those interested.

No need for expensive DC appliances. I use a chest freezer that is disconnected at night. Stuff still stays frozen easily. I do throw in 4 gallons of water to freeze to help keep thermal mass but if freezer was full it wouldn't be needed. For refrigeration I use a chest freezer as well but...

Hi all one of my battery suppliers has a decent price on 280 AH cells they are allegedly made new in 2020. I have been selling LTO cells on e-bay for a while now and have tested around 400 of them So I have a pretty efficient testing method set up. My thought is to bulk buy these 280Ah Cells...

Yes @Steve_S makes a great point Chargery does not necessarily market to the solar market. About the same time as Steve came to his conclusion to purchase a Chargery I came to my own as well. I was so happy with the product that I ordered 25 to have some here in the USA to help others get them...

I would fight this to the bitter end. For starters your system was not hooked to the house electrical system. Secondly who is to say that your panels were not just being stored on the roof. Did the inspector provide evidence that the system was connected to the house. From my experience most f...

Gosh Lets fill this glass up 'm not a glass is half full guy I'm like look at least there is water lets see how far we can get. Lets start with 30Kw of needed energy. For now lets forget about short winter days. 5 hours of sun 6kw of panels thats 20 santan solar. You can fit 22 300 watt...

Just want everyone to know that I will be going off grid backpacking from August 2nd to August 22nd. So if you try and contact me and I do not respond it is because I am hopefully high up on a mountain somewhere. For those who want to follow along if you are in to that sort of thing...

from my testing there is very little energy in charging them above 3.4 volts. less than 5%

Hopefully tonight I will be able to test my SSR's I have 250 Amp and 500 Amp ones. Obviously the first test is weather or not they work. I was also going to run them under load and check temperature often to see how they heat up with and without a heat sink. Does anybody have any other tests...

Forget the next person I need the wiring diagram as I will forget in 4 months lol.

I just finished milling the bus bars today after thinking about them for some months. This is a configuration I hope to deploy this week at my cabin. It is a 3p12s 120Ah 24V battery. Well almost finished. The big blocks of aluminum will get drilled to Accept 0 Awg cable and have bolts to...

One day I found myself 20 miles from anywhere with a dead car battery. So I scrounged around and found a tool battery and 2 paint bucket handles. Connected tool battery to car battery and 20 minutes later cycling between 2 tool batteries I was able to start my truck. Since then My satellite...

Keep us informed I think you will be pleasantly surprised with the results. You may have one or two items that need to be replaced but I bet you could find something of comparable price if something in your original list is not as advertised. I really think we pay about 3x as much for solar...

As per request I am going to try and explain how I get the Chargery communications to send its data to my PC. Right now I can read data from the Chargery. I have not played with sending data to it. For me one of the biggest benefits of the unit is that It will display each cells individual...

I first want to preface this by saying I am not encouraging anybody to use or not to use a Chargery even though I stock them and sell them to forum members at a discount. I only did this because they work perfect for my situation and I as well as some others liked the product. I noticed...

We tried that but it requires more hands on from Will. Bottom line is if you are feint hearted don't play in this forum. What we can do is move posts to other forums if they don't belong here.

Well I think we may have a winner! Tested this After 15 minutes at 50 Amps Temperature was only 71 Degrees F. Voltage drop was 0.1 V and Controll load draw at 12Volts was 0.34 Amp This 240 Amp relay will be about $40.00 including the beefy heat sink ($6.00) The 500 Amp relay I will...

So here it is Will dislikes the Chargery BMS. I don't disagree it's a bit quirky but. He proves how it is fully customizable even if it isn't for him. He does agree that once set up it works fine. I hope everyone who considers buying a Chargery watches this video. I am still a huge fan but...

Yes but the problem is if a cell gets out of balance the SCC can see the whole packs voltage but not each cells voltage. for instance 3.0+3.0+3.0+3.0 = 12 and in this case everything is fine. but 4.0+3.0+2.5+3.5= 12 if the cells get out of balance the SCC can not tell but your pack...

Like Steve said cooling will be an Issue. But I can see using lighted fans that could change color with state of charge. Or any led light that changes color. I quick glance could tell you your SOC

About 2 months away. I sold all 100 of last batch of else I would have some now. When I posted this I never planned to sell out so fast. Just wondering if the price point made sense. You can absolutely get cheaper buying direct. But you will also not know what you are getting. My intent is...

I'm going to say it depends. Most here on the forum believe that the BMS should be the controller of last resort. I have no problem with this statement at all. Others here say let the BMS controll more because it knows on a cell by cell basis how the battery is doing. I have no problem with...

I have thermal paste and I will be trying to rig up enough inverters and resistors to suck out a 200 plus amp load. I have 3 inverters a 2500,1200,and 600 watt all together that will give me 180 Amps at 24 volts if I can find enough things to plug into them. I also have some dc loads to...

I agree with Will 100% concerning the relays. Tgats why I do not use or stock the Chargery ones. I completely disagree about the LVD. Just last night I got here to my off grid place. And my batteries were low and it was raining. This is ok they were not so low as to trigger the inverter LVD...
