Yes you can. I make mention of that at the end 9:30 of this video. BTW I think that unit has a programmable neutral bond and uses something called common neutral. th-cam.com/video/D_KLSrsMI3E/w-d-xo.htmlsi=FQdJCY7OyIaAcwGj

Sorry about that. I did not explain that value much because it's not relevant for lifepo4 cells. Here is an explanation I found. The Peukert’s Exponent is used for the lead-acid batteries. Simply said this exponent is the ratio between the charging and discharging of a battery. It means how much energy you need to charge compared to the energy you get when discharging. For the LiFePO4 cells, the efficiency of the charge and discharge rate is very high - above 97% and more. That is why the Peukert’s Exponent is close to 1.00. The battery producers do not give this value because it is not necessary for the LiFePO4 cells.

It should be ok. Check this out. enjoybot.com/collections/deep-cycle-lifepo4-battery?gad_source=1&gclid=Cj0KCQjw8pKxBhD_ARIsAPrG45msO7Jkeo05wV0UCmtX45ygGywmLfSFUutvVnQuFMTFJJwFPGHFxXQaAulbEALw_wcB

Glad it was helpfull.

That's pretty good, actually. Thanks.

Hi. I have not heard anything on that.

Yes, but the charge controller should control that. .

Hi. Not earnestly. I have a few ideas but just haven't had time yet. Ty for watching.

Yes, there would, but the faster you switch it, the better it would be. It also depends on the switching device used. Some could work in a way where both batteries would never connect... like an A/B switch, but I would not advise doing this.. Either way you do it, you would need some heavy-duty fast switching device... why not just connect the batteries in parallel from the beginning...? Why do you need to swap?

@@natesdiysolar it's a project in which we will have stored batteries to keep constantly running a unit without having to wait for recharge. I have think about switching but I would not like to lose power even for a power flick. I'm planning to add diodes to my battery connection wires to avoid the current flow between them while doing the battery exchange.

@@spacerabbitk you would need a huge diode. Can't you charge while the inverter is running..

If it's just straight 240v, then it's not possible to get 120v . My inverters are 120v to start, and I use 2 of them to get 240v . You might be able to use a step-down transformer, but I have never used one myself.

@@natesdiysolar ok thanks man I got a step down inverter but it has a us 120v plug I'm not sure how to connect it

Yea, that's the worst thing is the low voc. The 1600w version even is 60v, lol

Yes, good point. Thanks for watching.

Yes, you could. If you see the project page on my website, a viewer did this. Just FYI, you will only be able to supply that inverter with the same amount of output watts of the buck. I think it's around 200w for that unit. So, connecting anything more than 200w would be wasted. You would only be able to get 180W (including conversion losses) of AC output... lmk how it goes.

Your panels would have to be in series, not parallel, in order to produce 50v assuming each panel is 24v. 2x 24v panels in parallel would produce the same voltage as a single panel, but the amps would be doubled. Series affect volts. Parallel affects amps.

Not sure . Never heard of cool bot. How does it work.

@@natesdiysolar tricks the thermostat to go beyond the 60-62 degree limit. Makes it think it’s warmer than it is. Mostly for digital units. Works on some mini splits.

@@Deveak I see. I wonder if it forces the compressor to run longer... not sure if that would be good for the unit long term. interesting device though.

Lol

@@natesdiysolar 😂

@@mariuszskoneczny2708 why do u say it's magic... just interesting?

@@natesdiysolar grounding...

Try out copper on your body let my no your experiment

Awsome. Ty for watching

Wow, 900kw, that's impressive!

I have not checked. I'll check and let u know. I'm not an HVAC expert, but I was told in mini splits w heat pumps that they run in reverse to provide the heating, so at idle, there is not much going on at all but I'll let u know what I find.

Thank you! Happy Easter! ❤️

There are other things as well. For example, you can not capitalize every letter if it isn't needed. A person can also use punctuation if they choose to. Usually those who don't aren't the brightest individuals.

It could be if you tested them under the same conditions. Do a short circuit test on each panel individually see how many amps are produced. Compare that number with the ISC value on the sticker .

@@natesdiysolar thanks, I was afraid to shorten them thus maybe destroying some cells. I have sent the pannel back. I wait for refund and order a new one. When the new comes I will connect them to two loads and see hownthey perform. Thanks for your fast response 😊

Yes, we'll 1,500W. See my pinned comment. 380V is the max voltage it can accept... Watts VS Volts

370w x 6, but you only need 1500w total to run it 100% . It will run on less it just won't be as effective. When on solar, the max draw was 800w, even though my panels could supply 1500w at that time.

@@natesdiysolar thank you for the very fast reply. I intend to get one of those, but up until your video, no one showed heating and cooling and what it took regarding watts. Thanks so very much!

@@benkanobe7500 I'll do a detailed video about that. I'll test with Just a single panel and keep adding. I kinda missed the mark on that one. I originally mentioned in the video that 1500w would be perfect but I took that part out because the audio had a lot of bg noise from the inverters running. Thanks for watching.

So when cooling, it was running only at 3amps. Does that mean that it was using about 3amps per hour? So if I have a 40amp battery, i can run it 13 hours?

@romanb78 you can not look at the amps. You have to look at the watts. This unit uses a max of 1500w per the specs. So 1 hour would take 1.5kwh of battery capacity. If you have a 200ah battery and it's a 12v battery. 200*12 is 2.4kwh, so you could run the unit for 1.6 hours.. but that's a worst case senerio. The unit will not run constantly.. it cycles like any other AC. So, in short, AC units, in general, are power hogs with 600w being the lowest on the least cool setting and 1200w at max.. have a look at the specs and manual. Hope this helps.

@@natesdiysolar thanks a ton for the reply!

Glad it was helpful! Thanks for watching!

Thanks. I actually did a series on my system. 6 videos with each video showing each step in the process. It's the ones with the blue stripe. In these videos, I talk about each product as I go. There is a playlist called 48v solar system.

@@natesdiysolargreat to know.. ill keep my eyes open one your channel ..looking at the direct solar input to water at present. I think to get this done is a game changer. I just ordered your custom buck converter. Im going to try in with 2 pieces 540 watt panels and see what i get out of it. I have 12 volt water element .. thinking of grabbing an old sauna hear element and seeing what i get without the converter and looking if I can get results with combo 12 volt elements or maybe a sand battery.. ill keep you informed..keep going ..love your work.

@byronsowntime thanks. Love to hear what ppl are doing. FYI. That buck converter will only be able to use about 300w of power from those panels. Whatever the output of the converter is in terms of watts is what you can hook up to it solar panel wise. You would need a larger converter. They do have solar water pumps that take solar input directly, but you should be able to run a small 12v pump from that converter.

Remember to remove your jewelry when working with any voltage. Also was wondering why you did not do the connection in reverse. Meaning connect the battery to the shunt and then the inverters to the busbars.

The battery was disconnected. I connected the battery last. Because I'm going to add fuses to the busbar later. If you mean put the shunt before the busbar. I will be adding more batteries and don't want many connections on the shunt battery side.

Thanks

Hi. So I have been working on a 12-Volt basic system video but have been sidetracked by other stuff. I have the system built and its on my website. This should work well with your plans. www.natesdiysolar.com/projects/12-volt-off-grid-solar-system/ If you think its to big then you can just get a smaller inverter and a smaller battery but use the same charge controller. LiTime has the mini series and any small pure sign wave inverter will do. I like Renogy for small 12-Volt systems. If you want to go cheaper still, just add a small 200w mini pure sign wave inverter to the SHTF project. If you do go with a battery, I would go with LiFePO4. one viewer did this but not sure what inverter he used, it was a 200w pure sign though. www.natesdiysolar.com/projects/shtf-emergency-solar-power/viewer-builds/thomas-k/

Cause it's cheap electronics from China :)

Typically you want to keep the Amps as low as possible by increasing the voltage as much as possible.. 15% under 150v max so 135v max.. when you cross that 30a threshold you must use 8awg pv wire.. its more expensive than say 10awg.. unless you have a short run... also when you go higher amps you must fuse each parallel string... that charge controller at 12v is suites well with 200 to 250w panels. Panels of this wattage will have a imp value less than 10a.. so you could easily have 3 parallel strings if you decide to go to a 24v or 48v system.. the more amps the more fire prone things can be as you are dealing with higher current. But if I had to choose from your 2 options. I'd go with #2. But in either case you need 8awg pv wire. 10awg pv wire is good for 30a. Hope this helps.

@@natesdiysolar You helping a lot , Thank you. If you put the systems in series, in this case is option 1 is better? More volts or amps do not influence the better/faster battery charging? Sorry for my bad english.

@Alexandree55 yes that would be a perfect setup. It does not affect the charging either way. The job of the charge controller to to convert that higher pv voltage to a charge voltage your battery likes. Watts are watts no mater how it's wired you will still have the same watts. Watts equals total volts times amps. If the voc of your panels are 24v then 6x panels in series would be 144v voc. That is just under the 150v voc limit.

Im pondering the setup with 6 panel 200w 23v in series, its for my RV. The only thing i prefer in parallel setup its when one of the panels is in the shadow the rest of them are not affected. Thank you so much Nate!

@@Alexandree55 that is true. Perhaps do 2s3p or 3s2p

I have not done any. That would be interesting . I think they produce AC power if I'm not mistaken. Do you know if they produce DC current..

Hi. I use this one made by blue sea . It's marine rated www.partdeal.com/blue-sea-systems-surface-mount-187-series-circuit-breaker-150a-7148.html?gclid=CjwKCAiAu5agBhBzEiwAdiR5tMAN3w2xUF3fM2aF0r_hciZhMq6VLGCQAKkktwIEkbfy5IX8vM-6uRoCF-wQAvD_BwE

It won't damage the inverter if you don't. It's just a common practice that people do. Newer rack mount style batteries have pre charge circuits built in but not all batteries have this. If you don't it will create a big spark when connecting battery for first time. If you look around you will see this. Did not see anything in manual about it.

@@natesdiysolar ah ok very good

I was wondering the same thing.

Glad you like them!

Yes it should run all that.. might not run the washer and iron at same time however.

@@natesdiysolar yes. In Pakistan people use solar hybrid inverters which support 100% load, while this dc to ac converters can’t take maximum load and high torque appliance. But in Europe people use dc to ac converters. Solar hybrid inverter of 3000watt can support 4000watt solar input as well and can work with out battery

What are the specs on the charger, and what are you charging with it. ..

@@natesdiysolar The portable power supply bank is charging straight from a solar panel but havnt tried it yet what specs you need?

@@natesdiysolar What's most important I should know? As specs info on portable power bank & solar panel are a lil different! Thanks mate!

@Saiyan4eva does the portable power bank take solar input directly.. if yes what is the max voc or solar input voltage and watts it can accept. What type of connector does it use for the solar input. Send links if you have link to the product you have

@@natesdiysolar Sorry mate Links for specs, keep getting pulled down by TH-cam, don't know why!

Battery is 5.2kwh . Inverters can produce 13kw
