Does anyone know of a database of manufacturers using LiFePo4 chemistry in their EVs? I really want to buy a used one for commuting to work, especially after adding the 3rd array and adding another ~15kwh of LiFePo4; the tax credit is the icing on the cake... I'll buy more batteries and maybe...

Has anyone done business with them? I'm ready to make an order, looking for last minute reasons not to. https://sunevo.m.en.alibaba.com/company_profile.html https://sunevo.m.en.alibaba.com/index.html

What would you pay for 48 CALB 230ah that have been sitting unused since 2022? What risks / issues are there purchasing cells that have been sitting? I think a road trip is in the works...

There were a few recent posts and a thread by a deleted member, VoltPolice, that were quickly deleted. I'm curious at to why, what rules were violated that made them vanish so quickly? Not even a new home in the chit chat zone?

Is anyone aware of 4s JBD's that support series connections? Tldr - will this or any other JBD's support series connection? (I know the description states series but I'd like real world confirmation) US $30.93 29%OFF | JBD BMS 4S 12V For Lifepo4 Battery 50A 60A 80A 100A 120A With Drop...

KG160F shunt, has been working fine for about a week, I noticed the display was frozen. I unplugged display, unplugged power to the control module, no luck in fixing. The Bluetooth app still works fine. What I've noticed is the display takes an initial reading, that is accurate, when it's...

Edit - solved. Shut off the other 2 breakers and isolated the problem child, started charging right away. Back to batteries and doing some laundry to drain them down for optimal photon harvesting tomorrow. I finished wiring up the 3rd pack and I can't get current to flow through the BMS...

Anyone see issues or reasons I shouldn't keep going?

I don't recall seeing these mentioned here. Is anyone using them for solar storage? https://www.prnewswire.com/news-releases/batterotechs-280ah-air-cooled-energy-storage-system-garner-multiple-international-certifications-301962976.html...

I'm planning ahead for adding my 3rd pack and having trouble deciding on a proper disconnect. I attached a crude diagram of the planned setup and a photo of how things sit currently (expect the SRNE is in service) the packs will be reconfigured and put in some sort of enclosure / rack / cabinet...

Should be a good thread... If you had to pick 3 firearms to use for the rest of time what would they be? Type, brand / model, caliber. I hope this thread doesn't hurt my wallet to bad 😂.

I'm probably over thinking this... I currently have an oil fired water heater and excess solar. If I were to add a small 120V heater before my current heater could I get the small heater to circulate and heat the oil fired tank? It wouldn't work if I just plumbed the new hot out to the old...

One of the best EG4 videos I've seen yet.

Should there be a way for the community to have a member(s) removed? Options below

I had another one of my bright ideas... I'm considering using 3 2x6's glued and screwed together with the grain alternating to make my posts for the mount. Why is this a bad idea?

Scenario - Was going to hook array ground from roof mount to main distribution panel since I never got around to it earlier. Heard a faint buzzing when the wire came in contact with panel frame and grabbed a meter. Reading 24VAC between the array ground and main panel ground, 0VDc between the...

Overloaded my TP6048 for the first time. I was going downstairs to fire up my 24v system and test some panels I picked up yesterday... Appliances running: Dishwasher on heated dry in drying cycle Pioneer 12k mini split (240v) set to 63f in dry mode 2 ceiling fans Upright HE washing machine...

Figured this was the best section... Has any dealt with removing a utility company easement? I'm looking at land, the high tension power lines were recently removed and relocated but there is still an easement on the deed... Of course this would be a prime area to build. My senses tell...

I don't remember seeing this discussed yet. https://www.swpc.noaa.gov/news/strongest-solar-flare-solar-cycle-25 Things will only get worse as we go into the peak, correct?

It's my first time using a hydraulic crimper, I have a feeling I'm doing something wrong (besides leaving to much wire exposed)... Temco recommends 8 pumps as a starting point for 1AWG, I'm going 18-20 because 8 doesn't even leave a dent. I keep questioning the orientation of the indent as...

Anyone running a Senergy inverter or know anything about them? Specs look promising. https://www.senergytec.com/product/energy-storage-solution/se-5-10khb-ul/ Discuss. Ps I was quoted $1650 plus shipping through alibaba (from a seller with a good tract record).

I see a lot of discussion on naming convention as well as confusion. I don't recall seeing a master thread so let's get one started. If this is popular enough I'll work on formatting everything better and throwing into a spreadsheet. Model - AC output kW - PV input kW - # of MPPTs - battery...

Inverter is specd for max 155voc panels are 40+voc, I also spy some other fails. Curious to see if they fix it. https://sungoldpower.com/products/complete-off-grid-solar-kit-8000w-48v-120v-240v-output-10-24kwh-lithium-battery-3600-watt-solar-panel-sgk-8max Doesn't give me to much confidence...

Thought it was a poor connection, not the case, same temps after a new wire. Noticed it yesterday.

Prime example of why you should draw everything out, check as you go, and/or not be a dumbass. Long story short I spent hours diying my buss bars to realize I f'd up. Solutions I see: 1. Order flexible buss bars from Docan or Ali, is aluminum scrap still up ? 2. Re-arrange packs because...

Does anyone see issues with cutting a small section (few inches) of rail and throwing a mounting foot on it so I can fit a 9th panel without having to use a long section? I have plenty of ground lugs and can run a jumper between if needed. I'd do this again on the W roof so I can fit 9 panels as...

I didn't feel it at work, lots of equipment running. Others in non manufacturing areas felt it. Looking at SA data there is a drop on my ground mount about the same time it happened, dropped to ~250W Coincidence? Anyone else see or feel anything?
