Multi Billion Dollar AC Industry Destroyed and Other Scam Advertising

The fact you are using "scare quotes" affirms my whole point! If you don't know what scare quotes are, look it up.

Does a solar generator with solar panels with sunlight generate electricity and store it? Simple question.

As I said I get the impression

I asked you a question in context of your DYI project.

For this..

What’s the battery capacity, with what charge rate with what rating of is solar panels. With what connections to charge / run what equipment.

Again does it match the durability, the portability, the amp hours of the battery, and the specs of say a 2400 watt solar generator with 500 watts of solar panels.

Say. For RV / off grid living. Compared to your DYI project.

What’s the cost and weight of the battery in your DYI project. What is the amp hours of your battery?

If the weight is mostly the battery, what’s the difference if your DYI project gets a defective battery. Or you don’t get the circuit right, or the DYI circuit under protects the battery, or isn’t programmed very well for optimum charging and you kill a new lithium battery.

Infact. The manufactured solar generator it’s going to have protections and control charging rates to protect the battery and maximize battery life. How does your DIY project protect the battery, how does it maximize battery life.

Except for being careful not to short the battery, which can be a hazard working on a car too, looks about like working on old tower computers.

You’re just being unreasonably ignorant over something that’s not a big deal by those that use them.

I have no problem working on old tower computers, or cars, have done both for a long time and parts are easy to find. But you still haven't provided any information to support your claim you can work on these the same way, I don't find parts for these like I do parts for old tower PCs and cars, but speaking of car parts, the OEM parts are often overpriced and the aftermarket parts can sometimes be junk. Actually I worked at a car parts maker and sometimes if we had parts that failed the OEM specifications, we would ship them to the aftermarket buyers because they didn't require the same quality so I have some insider information on that.

Thanks for the warranty info, but I'm still concerned about after the warranty expires.

I looked up leading solar generator on Amazon.

Below is the first thing that came up?

People in general had good luck according to that summary, but there are some lemons and how did one customer manage to buy five of those and have only 3 out of 5 work? They also had problems trying to get warranty service. It gives me pause at least:

Style Name: Solar Generator 3000Pro 400WVerified Purchase
We bought 5 of the 3000 units, two for us and 3 for immediate family members. We bought 2 1000 units for family members that the smaller unit made more sense for than the bigger 3000 units. We also bought the stackable expandable 2000 units with expansion packs hoping to run the house and well on it. And LOTS of solar panels so everyone had what they needed. All in one month during the sale. So when I right this review, it's not based on one lemon unit, or just a complaint with little founding. We went all in and gained a LOT of experience in a short time. None of it was good.

The 2000 units, stackable expanded, are advertised to be able to run a house, could not. We only have 2 refrigerators and hot water heater, and the well. It could not run the well. Even though we bought all the expanded power needed it was not high enough. we were not trying to run an air conditioner, or something big. (not even the hot water heater or a stove hot plate). Just enough to get through a hurricane more easily. But water is key. it's a regular 1 horse pump, not an industrial well. So if you are looking for a house back up unit look else where. Thankfully that one was easy to return, just time consuming.

Out of the 5 (FIVE) 3,000 units we bought, 2 were bad. TWO. That's a lot. We charged them, and then put 1 (ONE) normal new and newer house midsize refrigerator on each and both were dead in under 24 hours. we charged them and tried again and they worked for even less time. We charged and then took a battery charger to charge 4 (FOUR) AA batteries (energizer brand) and it took 20% of the jackery's power to charge 4 AA batteries. Something is very wrong. but it gets worse. we fought customer service to send the two defective units back. They needed us to to the math for them to show how and why the 20% of the entire jackery to charge 4 AA batteries was not normal and that less than 24 hours on a house fridge was not right. The onus was on us and it took a while and quite a few photos back and forth to explain to them what a AA battery was. That was confusing. Where ever their support folks are, they don't know what AA batteries are, what they power, how much power they hold, and why 20% of the jackery isn't right to just charge 4. (Energizer, not no name brand) Once we won that war and got a battery and math education so we could fight it, they allowed us to return the TWO 3000 units, but took 6 weeks to send us replacements. So a total of 10 weeks after we purchased the units, we received our units - and they were obviously used and also did not work. One does not hold a charge and smells TERRIBLE when it is on - so bad it gave me a headache and we had to air out the whole house, the other one the back door will not close and the front plugs don't work (yes, I know to push the button to turn them on. it does not work) so we asked for our money back and they said we are past the 30 day policy but they will buy them back from us for $800 (likely where these two came from). We spent $3,000 on them, each, and they admittedly agreed per their offer that these "new" units are really only worth $800, hence their offer. Ironically, we have two prymax units that were $900 and $500 (on sale), same power capacity as these jackery units but I was sold on the battery life pitch and thought they would last longer than the prymax. I wish we just stuck with pyrmax.

Now we are stuck with 2 3000 units that don't work at all (The "new" obviously used units they sent to replace the 2 new units that didn't work) So out of a total of 7 SEVEN 3000 units all together that passed through our family 4 FOUR are broken. Of the 2000 expandable unit, it cannot power what it says it can on their website, so that was no good. and the two 1,000 units have been good for what they do.

Just a note, we own 2 prymax because our electric goes out in storms often and we need to be able to keep working even when it's raining or storming. So we use them often. we will get a three or four hour storm once or twice a week, and these units on one charge will run the laptop and speakers and internet (not much!) for weeks before needing to be charged. The Jackery would not run the same laptop, speakers and internet for two storms (when it worked for a short time) There is something wrong with the way it discharges electricity and that can hurt the computer. Plus the smell is unbearable when they run. The prymax got hot and the fan is loud, but it out performs. (Sorry those two names are the only ones we've had experience with. I'm not promoting prymax, just comparing our experience.)

Just passing on the information for the next person to be able to make an educated decision on what to try if they are looking for a solar unit.

Infact. The manufactured solar generator it’s going to have protections and control charging rates to protect the battery and maximize battery life. How does your DIY project protect the battery, how does it maximize battery life.

You didn't watch the DIY video yet I presume? It's got the protections covered, and to control charging rates, it has a special controller. You are accusing me of not understanding this stuff, but based on these types of comments,you seemingly fail to understand what the controller and protection circuitry shown in the DIY video do (or you simply haven't watched the video). In fact the DIY setup even has some extra optional components he calls "shunts" that he says can assist with troubleshooting any problems, that I haven't seen in the off the shelf stuff like Jackery etc. I'll even re-post the same video for you here:

How To Build A Solar Setup: COMPLETE Step-by-Step, DIY Guide (12V, 2000W)


11:11 he explains the optional shunts.
18:45 he explains the solar charge controller.

It's a little clunky the way he built it, but he wasn't going for a portability, and for my use I'm not sure I really need portability, but I'm still mulling over what else I might use it for so I could end up going for portability after all. You don't have to build it exactly the same way as in the DIY video as long as you know what you're doing, and the video is helpful in achieving that objective, of knowing what you are doing, if you understand what the video explains. If you don't, it's better to spend the extra money and go with a pre-made unit, and take your chances that it will work reliably.

I had to smile a little, please don't take it personally. With your basic knowledge, you shouldn't be fiddling around with electronic devices anyway.

It's one thing to replace spare parts or put PC components together. These are plug & play parts, it's not a big deal and you don't need to be able to do anything except have two hands and eyes. That's really nothing to be proud of, especially if you have jokes about string theory in your sig. If you expect this level of convenience from electronics, you have to do something for it.

There are plenty of spare parts, you just don't know about them. The reason you don't know about them is that you don't know anything about the subject.

People in general had good luck according to that summary, but there are some lemons and how did one customer manage to buy five of those and have only 3 out of 5 work? They also had problems trying to get warranty service. It gives me pause at least:

Please don't be so naive. These are Chinese products. Buy something decent and you'll get something decent. You get what you pay for. If an inverter costs a quarter of the normal price, then something is wrong. I had a PV system built 16 years ago, and for 16 years the inverters have been running without any problems at temperatures that fluctuate between -15°C and 65°C.

Designed for what battery and what amp hours.

and to control charging rates, it has a special controller.

For what type of battery? For what amp hours. Tested and verified how to maximize battery life? For what battery?


Your DIY sounds about like the things you are protesting?


With you not providing the very important information. What is the amp hours in comparison to the examples of solar generators provide.

What is the amp hours of your DIY project. How portable is it. What is its weight and size compared to a typical 2400 watt solar generator. You made a big deal about weight and returns. How does the batter differ in your DIY in dependability, and weight, failure rates. If you use your DIY setup to charge the battery, is it still covered by a warranty. Or is it void?

a reply to: Arbitrageur

Watch your video.

The well setup I posted is more efficient because it doesn’t go through an inverter, it runs a DC pump.

Shrugs.

a reply to: Arbitrageur

The wires to the batteries from the inverter runs at 166 amps?

a reply to: Arbitrageur

Actually, the name "solar generator" is sort of a naming scam, because it's not a generator. It's almost as misleading as trying to market the air cooler products as air conditioners.

Whether you like it or not, it's a generator. You can harp on about this term as much as you like, but that's how it's used in the professional world. Because you have no idea what you're talking about.

A PV module, also called a PV generator, actually works on mechanical energy if you want to be as precise as you do. The kinetic energy of the electrons is converted into electrical potential separation.

I really don't have a university degree, but I knew that too.

a reply to: Arbitrageur

You’re going to size a switch from the inverter to the battery for 166 amps?

How’s home owner’s insurance feel about the DIY?

In fact the DIY setup even has some extra optional components he calls "shunts" that he says can assist with troubleshooting any problems, that I haven't seen in the off the shelf stuff like Jackery etc. I'll even re-post the same video for you here:

Don't even know what a shunt is but want to build a PV system yourself and act on the internet as if you know what you're talking about. Man oh man. And you haven't seen any shunts in off-shelf components? maybe because you don't know any and have never seen any? This is ancient technology and my inverters have shunts. They are from 2008.

I'm going now, that was my last comment.

cough scare quotes cough

a reply to: Arbitrageur

So?

This



will get you this?



With two of these batteries?



So 2560 watt hours?

This for less, gets this. It is only 2042 watt hours vs 2560 watt hours.
