Now, im not trying to make enemies here but NPR is FAR from as left as it gets, and it only seems that way because media skews the perceived 'acceptable range of opinions' which is really the 'profitably publishable range of opinions', far to the right of what it actually is at ground level...

Unfortunately there is a bit of a gray area in terms of how small a generator you can use, even IF you can set a limit on how much the inverter will pull from it. What you can't control is how quickly it applies that load to the generator. If the inverter ramps up the load slowly even a tiny...

So... this sounds... horrendous. I enjoy talking about solar but from the list of downsides and gotchas you spelled out.. I would be in 'preserving the evidence' mode and not touching anything in worry of the company trying to counter-hassle me for tinkering with things THEY OWN, when we're in...

I tried some 3M 5200 adhesive sealant one time (never worked on boats or been to Vermont) and it was tenacious and impressive. Also so sticky and messy it was a real double-edged sword to use. :ROFLMAO: But.. get this. I drilled a hole into a carburetor body to get to an internal check ball...

It was not known to me when i bought my first inverter-driven aircon that this was a benefit of them, but now i feel like it's the second biggest benefit they have and it either is(i didnt know, you didn't know, but maybe we're the only ones?) or hopefully will be soon a well-known fact in the...

Well guys, it’s real. ? Haven’t had time to do anything but open the box. Or to figure out how to rotate pics uploaded from my phone. To be continued..

May sounds funny but consider that adding panels to offset voltage drop is probably cheaper than burying larger pieces of copper! Voltage drop is different in ac and dc in that the ac devices work in a narrower window and may actually be damaged by low voltage conditions. On the dc side your...

Lots of good advice given already in a short number of posts. I would just emphasize the ‘basically no inrush’ benefit of variable compressors because even though you have a 15k inverter, if you ever want to run multiple compressor-equipped appliances at once on it you have to consider the...

Really glad to see that it holds settings after power loss. (y) (y)

In practical terms setting a bunch of glass objects right next to a neighbor with a perfect excuse (field=tractor=bush hog=prove the origin of this rock LOL) and then irritating him, is a really bad idea and in all likelihood the law will not help you deal with him until the situation has...

This just corroborates that the voltage readings are due to a large voltage drop because of poor connections. Voltage drop only occurs when current flows, so at rest it will appear normal.

Yes, the downside of a tax rebate is you have to have to pay enough tax to be eligible for the max rebate to begin with, which basically means almost all of the tax-related solar incentives totally skip over people at the bottom of the income totem pole, which is unfortunate because they...

So you only need to 'protect' the mppt from volts, not amps. The mppt will only allow as many amps in on the solar side, as it takes to max out its 60a on the output side. If you have more potential watts and amps hooked up to it than what it can actually use, you are generally just making it...

So i'm late to this thread but for context, this is what i said about cars in another of OP's threads: So i am basically against 'bothering' to do 100-something Watts from a running car unless you are also driving it, because the engine takes about a couple thousand watts of power just to...

So one of the big downsides of lithium batteries in general it seems is that they can't deal with 'excess' charge, so they have to refuse to accept it by having a BMS either limit or disconnect the charging current until whatever cell imbalance or voltage issue is resolved. Unfortunately that...

So remember that the EVSE is basically just a ‘smart’ extension cord but really does nothing to the ac power passing through it other than turn it on or off. The vehicle’s onboard charger is the one converting that to DC and feeding it to the battery, and controlling the current rate based on...

Another way of putting it is that numbers like 80 and 100a almost always refer to dc because there are basically no 120v circuits intentionally designed to flow 80-100a other than the neutral conductor between a house and the utility’s transformer, and at 240v that would be an absurd power level...

I would suggest starting a new thread explaining what you built and perhaps linking to this thread as an explanation of the problem you were trying to solve. I would definitely like to read about what you built. I did one time buy a little adjustable voltage switch that would adjust up to...

Just bought the "last one". ~$405 shipped Thanks for the tip. (y)

Well, im digesting little tidbits but still confused about the same things i posted. But that’s noone’s fault, i’m using a free service and getting more than i pay for reading here. I appreciate all of you willing to share what you know and trying to muddle through all the misunderstandings and...

The only way that charge sources of that size could get a 140ah lifepo4 to go from 12.7 to 14.6 in 5 minutes is if there's a bad connection in between them. It wouldn't be the true battery voltage, it would be battery voltage + a voltage drop in the circuit somewhere. If there were no resistance...

The approach that would require the least amount of re-engineering of the car itself is to simply interface with the existing battery through a dc-dc converter rather than replacing it entirely. In that way the pack voltages don't need to match and whatever the car needs to sense/measure from...

Just to point out.. any time you get ANY dimension on a drawing you can usually get a pretty good idea of anything else that is on the same 'plane'. On a pc i usually just do this in microsoft paint because any time you draw a line point to point you get a pixel count at the bottom. So i just...

Reading this thread has made me realize that i've already forgotten some of the things i did to make my Growatt+autotransmformer setup work, and that makes me nervous. Since im now out of the 'proof of concept' phase i think i need to go through my system again and make sure everything is proper...

Short answer yes, but when you say pick it up, id be mindful of what all they can lay eyes upon on their way in or out. People that recycle copper often have a 'good eye' for 'opportunity'.

I had taken that tank out and cleaned out the sediment a few years ago. It always worked fine between then and now, but i noticed when i went back into it this time that i had miswired the elements when i put it back together. So all this time I thought i was operating on 2 4500w elements in the...

I just bought a 140ah 12v battery for $400 on amazon, because i waited a little too long and let the discount to $370 expire. I would recommend going to lithium and making the minor accommodations to keep it functioning in your climate. Honestly, unless your battery bank was functioning one day...

Eventually, yes. But the practical limitation is that the correction of imbalance with a purely passive method which has a steep diminishing rate of return as the voltages get closer together (ie slows to almost nothing) can easily be outrun by the accumulation of imbalance in the first place...

The only way i wouldn’t be extremely irritated by all the parallel wiring id have to do to get 7000w of panels hooked to a 24v battery through a bunch of PWM controllers, is if the panels were arranged in a circle about 2 rings deep, and the batteries were in the middle. Considering most 200+w...
