You can keep your Tesla charged up with only 5400W of panels? Where do you live that you can get that much sun?

Not sure I get what you're saying there. Replacement of internals of the 6500?? That doesn't seem practical or wise at all. Why wouldn't some kind of cart/dolly-based setup work for your portability requirements? The Ecoflow Delta Pro Ultra would be just about perfect for a commercial...

EG4 Complete Hybrid Solar Kit - 12,000W 120/240V Output + 30.72kWh EG4 Lithium Powerwall + 14,000 Watts of Solar PV [KIT-E0005] Very misleading description. I don't even see an option to get 6x batteries, just 3x. I also wouldn't call a server battery cabinet a "powerwall" but that's...

How do you not have control over your data with Home Assistant? What are you referring to, specifically?

An extended grid down scenario will very likely be caused by an EMP. How you going to shield your system?

This guy is connecting four 12V 200Ah batteries in parallel using 2/0 wire, but 4/0 wire from the bank to the master switch.

No.

Building a DIY power station that I am thinking about leaving running 24/7 for powering some electronics. Specs are: - 12V 100Ah LiFePO4 - 500VA inverter (Victron Phoenix) - 30 charger (Victron IP22) Rather than running the charger in charger mode would it be better to run it in power supply...

It's details like this that I wish YouTubers would explain more. From all my reading it sounds like fewer strands are easier to crimp and generally have better results. Also with the higher strand counts they tend to be tinned, which is not recommended for crimping. But for screw terminals...

Do you prefer low or high strand counts, especially in larger wires (say, 8 AWG and larger)? I just picked up some 6 AWG Southwire brand wire from H.D., 19 strands. I see some on Amazon that have 3200 strands. Quite a range.

Well the OP is talking about using the battery, not keeping it in standby. And you can always just charge to 80 or 90%, though again if the battery is being used then charging to higher SOC is fine.

Will be interesting to see if the server rack batteries try using the pouch cells. Should be able to pack 10-15% (?) more Wh into the same space (for a slight increase in cost). Should also help on the weight.

I notice the default absorption time is set to two hours fixed for the Li-ion profile. Isn't that rather high? I've seen one source state it should be no more than 15 minutes. I know it depends on the battery and the manufacturers recommendation but still, that is a wide range. But does it...

Isn't 14.6V a bit high if they are at rest? How long had they been off the charger when you measured 14.6? 13V with the load, right? V will typically drop 0.5-0.7 under load.

+1 on using a shunt. The curve of a LiFePO4 is just too extreme on the ends and flat in the middle to really tell anything about SOC other than you're about > 90% or < 20%. The chart in the Chins manual doesn't seem very accurate either. I just got a CHINS 12V 100A, it arrived at just under...

They have to be cutting corners somewhere and the main thing would be to use grade B cells (do grade C cells exist?) Would love to see someone do a capacity test and tear down on one of these.

Will endorses Ampere Time and Weize on his site. Chins, Ampere (Li) Time, and Power Queen are generally well regarded. https://www.mobile-solarpower.com/lithium-batteries.html Two Chins 300Ah running for two years, no issues. Not bad for a junk battery.

Not that bad, not for LiFePO4. Cycle life: > 2000 cycles at 100% Depth of Discharge (DoD), up to 5000 cycles at 80% DoD

Really a lot of bang for the buck here, even with the $55 shipping. It's perfectly sized for a 12V 100Ah battery. Will be interesting to see how long the inverter and solar CC last, they must be pretty cheap components. I may go with the DC box and add my own inverter (bolt it to the top or...

I can think of a few right off: - need to step down to 12V for 12V loads - potentially more difficult to find 24V replacements quickly Most van-lifers get by just fine with 12V and some have some pretty high wattage uses.

Just small loads around the house, mostly for outages. I will be building a larger system as well, but anything more than about 400W I may as well go to 2000-3000W so that I can power microwaves and such. There really isn't much, if anything I need to power that falls in the range of...

Doesn't seem to be a lot of choices besides ultra cheap junk. Victron has plenty of models, like a 500VA for about $165. The smallest Renogy I've seen is 700W. Will probably just get a Victron instead of trying to save $50 or $80.

How long can you realistically get along without electricity?

Pouch cells are actually more reliable and safer than prismatic? https://www.litime.com/blogs/blogs/prismatic-vs-polymer-lifepo4-batteries

These will be very popular, unless time shows there are issues.

Are you in a location where a little wind generation would be possible. The nice thing about wind is it typically is the opposite of solar, day to day. If solar generation is bad, wind is up, and vice versa. It wouldn't be enough to replace a dinosaur-fueled generator, but it could save fuel.

What's your budget? For about $2500 you can have 5kWh of battery with around 3kW of power. Bedrooms and baths use almost no power unless you are running a TV or something (should not be using hair dryers during a power outage :)). LED bulbs are so amazing.

Renogy is another option.

Their Sun Inverter and smaller combo inverter/chargers are 230VAC only.

Depends on the cell (energy density) and case material/strength and whether you want to absolute best cycle life. Also, how do you know the manufacturer actually did the proper compression during break in? It does seem like in most battery teardown videos there are very few actually...

It sounds like EG4 has made upgrades to always pass through the grid's neutral bond.

Tracking is not worth it IMO, for most circumstances. How much energy do you actually need for a mobile application like this? I think manhandling a 400W panel up and down and everything would get old fast.

First Solar's panels (American made BTW) are really meant for huge solar farms but if you can make use of them, why not.

Even the engine?
