BHU has added a TON of LIFEPO4 cells in recent time. I remember they were all like 100% 18650 or cell packs. Now it seems like there's a flood of LFP cells which is great. It's kinda surprising how they are still around $1.60/Ah when the ready made 100AH packs on amazon are around the same price...

I have this unit: https://www.giandel.com/products/ps-1200jcr Just curious to know what the issue with my inverter might be... I haven't had any issues with my unit so far. I currently have 200AH LIFEPO4 hooked up to it with 2AWG wire. Everything is nice and tidy. I attempted to charge my lawn...

I should be getting another 100ah battery this week along with an additional 100w panel. I plan to go from 3 panels in parrallel to 2 in series and 2 in parallel for the increase in voltage to support 400w.

Does anyone know the actual dimensions of the internal cells? I'm curious if you can weld together two full size battery cases and fit like 3 sets of cells if you rotate them 90 degrees...?

Not sure how lightning deals work but picked up another full size 100ah battery for $167. Excited to get a 2nd. First battery is working like a champ...

Here's the manual - https://cdn.shopify.com/s/files/1/0746/0415/1079/files/POW-KEEPER-Series_User_Manual_bb3569ba-b8fb-44af-b705-ef13f9c0da9e.pdf?v=1686640659 I have no issue pulling current. I'm not tripping the battery bms. I was down to like 13.3v and it still wouldn't turn on charging...

So new issue... I finally was able to reach full charge on my 100Ah battery with the new MPPT controller. Yes, it is about 30% more efficient on the full range of charging, cloudy days I can get like 35-45W and full sun in Feb I've been able to get up to 292W which is pretty good for 3-100W...

Not sure what I'm looking at but it seems to be working good. I was able to wire it up and program it for lifepo4. We shall see how much it tops off the battery. Had brief sun this morning and was getting around 250w from my 3 panels around 10am before the clouds and rain rolled in... So I'm...

Yea, I'm definitely taking my own path I guess... I'd like to have a better way of monitor my battery SOC... thinking of getting this hall sensor monitor...

I'm looking at getting the pow-keeper1240 mppt charge controller from PowMr. Love the name. Lol https://www.ebay.com/itm/354925340491?mkcid=16&mkevt=1&mkrid=711-127632-2357-0&ssspo=z8FtN-I_RIu&sssrc=4429486&ssuid=42adkWcYQ3O&var=&widget_ver=artemis&media=COPY I think it's authentic but not...

Do tell on your end result. I have 1 and don't really have the equipment for capacity testing...would love to pick up a 2nd...

Ah, now it makes sense. I always wondered why the voltage from the panels drops from 23v to whatever the battery voltage is, ~13V on the solar side even before the PWM controller...I guess it also makes sense when I see the battery voltage increase, I end up getting a higher charge wattage due...

Panels are 3 in parrallel, they're about 23.1v no load. I'm only talking about maybe 275w on their best day with 3-100w panels. I didn't see any conformal coating but I also didn't do a ton of prep ahead of the modifications. I'm just on a small 12v battery setup for now. 100ah. Looking to go...

I received my 3rd controller now. Did alot of research and aparently there's a larger version of these pwm controllers that actually has a metal heatsink on the back.. The new controller is very nice and actually has 9 fets so definitely should be an upgrade. The soldering was very poor so I...

So the solar charge controller (30A version) caps out around 215w and starts to thermally throttle. I suspected it has something to do with the limit of the mosfets just exceeding their current limitations. So I ended up getting another solar charge controller, this time with a different layout...

I have this exact battery. I purchased it about a year and a half ago. Not used a ton, few road trips with a pure sine wave inverter to power a laptop. I can easily pull 300w from it too. Still can't believe how much I paid for it back then...

So been playing around with my setup over the weekend. I did some poor math and research and undersized my solar wire WAYY too much. Ended up going with 14awg wire and I'm currently pulling around 10A in full sun, planning to add 1 more panel. Based on my calculations I'm getting a pretty...

I just picked up this battery. Should have it later this week. It's down to $210 currently.

OK all. Quick update. I ended up getting the Giandel 1200W Pure sine wave inverter. Got it for a decent price, $130 out the door... I also purchased my first set of solar, 2 100w panels and a cheap PWM charge controller (I'm not pulling a lot of solar so the cheap PWM was probably my most...

Link. I don't see anywhere where you can get 2 for 384....

Yes. I took it 1 step further when I was a kid at my parents house. I wired a Y for an extension cord to a 240v air compressor. Plugged in each 120v plug in an outlet in the house on separate legs from the breaker to make 240v. Worked great, just always knew there was a live prong when plugging...

Hey all, I'm planning on getting an off grid inverter 1200w to power my small office. I work remote so I'd like to power my office entirely off grid. Can I connect my inverter with the wonderfully safe male to male 120v cable to an outlet in my office with the breaker at the box switched off...

I just did some back of the napkin calculations for the cost of a small solar system and payback period. Doing all of it myself as a grid tie system I’m seeing a 6 year break even time at current electric prices + the 30% EPA tax credit… Not sure if increasing or decreasing the kw size would...

Thanks for the advice. I think what I'm more concerned with is the price per kw. I've done what feels like extensive research and it doesn't seem like I can even get under $200/kw at current prices. Even with building my own pack with cylindrical cells, some come out to be more expensive that...

Hello all! First time post here. Glad to see this forum has quite the life to it. I'm new to the LifePO4 world and energy storage. I live just outside of DC in a suburb of Maryland. I'd like to slowly build up an energy storage system. I originally purchased a TalenCell 24Ah battery to replace a...
