This series is a true keeper. Thank you! Yes, take his advice and do them in order, for sure! Also, don't forget you can read/copy the transcript if you do better with reading along!
I've been learning about solar systems for decades. Man, the technology today is like magic. I opted to go with a permanent solution on the house. 10 Maxeon 425 Watt panels, 10 microinverters, monitoring system, 1 racking system and 1 Tesla Powerwall 3 and Gateway 3. 25 year warranty. This should give me 2 or 3 days full house backup power supply and switches over automatically. This system really impresses me (uh, maybe it shouldn't?) Of all the 'studying' I've done, YOUR CHANNEL is by far superior than any other I've listened and learned from. And, even with my knowledge over the decades, your channel has prepared me to make a good decision on an in-place system. Gulp, maybe I should wait to say that until you've made a comment on my system. You get 10 stars out of 5! LOVE YOUR CHANNEL. Thank you thank you thank you!
Your time, effort, and knowledge is greatly appreciated. Now, I just need to watch these videos a couple hundred times in sloooow motion (pause/think, pause/think). Maybe then I will have the content in long memory. :)
Thank you for the time and effort you put into educating this series of videos. The terminology has always been confusing and difficult to grasp, not the basic math. Though the terminology is still confusing, the concepts are much clearer. I feel very confident that with another listen of the videos in this series, I will have the understanding I've been seeking. Again, thank you for doing this. Very much appreciated. Very helpful! 👏
Another great class Professor!! I’ve been playing with the equations as all relates to my EcoFlow system and how I want to run things camp/rving. Great exercise for me to hopefully get this knowledge to stick in my head!
@hobotech I would like to see you make a video on the ways to ground solar generators in different situations. Like using them in Rvs and outdoors if needed. Thanks.
Very clear explanations in this series. How do you usually factor in (roughly) conversion losses from the inverter going from DC to AC in the case of AC appliances?
Take the result x 0.85 to account for 15% inverter loss. Thing is a good inverter is 5% and a bad inverter is 25% so unless you know what your inverter loses, you have to guess. In the case of power stations I test that for you.
Thank you for this lesson. We have always wondered how you could solar power and air condition an RV in Las Vegas' triple digits summers 24 hours a day for months at a time. We guess the issue would be the weight of the 3600 amp hours of batteries plus the amount of solar panels to charge them. Would this type of array even be feasible, or would you need an additional storage area on a power station type trailer? How much would this extra towing weight be? Would be great to incorporate in an RV build.
Good basics coverage. It's 22c/kWh down here in Pueblo. Up in Denver it's only 14c. Trying to get solar, but the company is slow walking me. Don't wanna get too grumpy with them or they'll make a 'mistake' on the install and suddenly I need a new roof. :( As soon as it's installed though I'm going ham on all the social medias.
Thank you professor. Im going to sit the kids down to watch and learn all this. On a side note: I have home solar on the roof. I seem to always have a few $100 true up payment at the end of the year. To get the company back out to add a panel costs a ton of $$. I bought 2 of those 200w Type N panels and they are just sitting in the closet. I heard there might be a way to plug them into a home socket (need something to do the inverting and something to plug into the wall? to help with extra net metering. 1) Can this be done? 2) how can it be done. is there some amazon thing. That can plug the panels to the wall and keep things in ..phase. Or can I straight connect the Mc4 parallel cables (late at night so I dont juice myself) to the home sunny boy inverter. The older inverter is cool and I was able to install a power socket to it so even if the main power goes out I can switch it over and use that. .. Im mean.. what could go wrong 😶
Mr Hobotech I have a question or 2. Good classes but only the tip of the iceberg 😁 Who knew. I agree need to watch again. I have a 2024 Nobo 16.1. It came with 400 watts of solar on the roof wired in parallel they said and 2 64 ah interstate agm batteries also wired in parallel they said. I honestly have not tried yet to see if thats true. There is a 2000 watt inverter which is supposed to switch automatically when hooked up to shore power and vice versa. I have a 12v fridge and tv, a 12.5 btu ac, microwave and propane heater. I hook up to an ecoflo pro with xtra battery and charge that off my f150. Have solar panels i haven't worked out yet but anywho everything works except i have no ac at the receptacles. People have said could be the connections at the receptacles wired in series. Makes sense but i am wondering if my batteries are too small ? I may have gotten a little lost in there when you were talking about battery size. The other question is about mppt cables coming from the panels to the generator a normal sized cable going a 100 ft would be too small? 3 400 watt panels was going to wire in parallel because everyone seems to say that's the way to do it. I got the connectors but broke one so put it aside till i can get it fixed. Anyway 🤦 Thanks for your help.
Sorry if this is in the wrong place. Will the 12v/24v Lead-acid Battery Charging Cable also work the same on LiFePO battery terminals? Will really appreciate if someone knows the answer. Thanks
Was wondering if you could do a video on how safe it is to have this scenereo ... four different solar power generators - solar into the first one with each other unit connected to the AC out with the final unit actually supplying the power to whatever. As a result the units are all charged via the first unit which is solar charged. Is this safe and is it safe to increase the say one kw output of each to four kw output adding up the total capacity of each unit connected.... though depending on the actual size of each unit the resulting total kw may be different in the end. Am I making this difficult to understand lol?
Do devices draw more current as battery gets low? I'm trying to understand.. If I use 1200W coffee pot and my battery has gotten to half of its capacity.. So, the voltage has dropped, does the coffee pot increase current to get its 1200W? And I can ultimately fry it when the battery is almost completely drained? Also, does voltage matter when choosing cables? if I use 120V and 40A load i need #10 awg.. but what if I have only 12V pushing the same 40 amp? I mean now the pressure/push force pushing the same 40A is ten times as less. So less (friction/resistance) and also less power travelling through a conductor.. Can I use #14?
I have a question about a Jackery solar generator. Can you plug in two different sources to the input of a Jackery? e.g. 12 v accessory from a car and a solar panel. All Hail Odin.
I was disappointed that you did not talk about inverter efficiency (or lack thereof). I'm guessing you considered that it make make the heads of the target audience explode to calculate in that complicating factor. You missed Power Factor as well, but that concept is well beyond the target audience.
okay, this seems almost too easy. So if i have a household refrigerator using 547 kWh/year, that equals 1.5 kWh a day(1500 W) or 62.5 W an hour. So, a 700 Wh sogen should give me about 11 hours of runtime? of couse that doesn't take into account any startup surge.Is it that easy? if i finish all 3 vids do i get a certificate of completion?
hi i bought a battery off amazon it was the lowestprised lifepro battery i could find couldnt find any reviews on it has 12.8v 100am hours the name brand was ingeosolly.12.8volts I bought it for the price bought alligator clips for it to in cas of power outagage to slow harge my Bluettie 180. It is slow charges at about 100 what hours can you review this? ty Billly B. i bought it a while ago but never have seen a review. thanks. Billy Barnes

OMG, this outfit is great. You're such a legend dude. Such a fun way to present educational content. 😂
Great video for the dyi
Very good series, you have a deep understanding of this topic and convey it in an easy to understand manner.
Thanks again for a truly great presentation. The discussion of watts really helped put it all together.
Thank you so much for this series! Helped a lot!
Thank you sooo much, I just wish the university could keep going. The information you put out is great.
Watched all three lessons! Thank You!

Shockingly useable info from the Professor.
Love your Professor get up. Looks great..
Great job! Thanks Hobotech!
Enjoyed the video. Thanks for sharing
Excellent video!
The data in this series would be incredible if incorporated into an app!
Another great class Professor!! I’ve been playing with the equations as all relates to my EcoFlow system and how I want to run things camp/rving. Great exercise for me to hopefully get this knowledge to stick in my head!
Would love to see a discussion on post lead-acid battery chemistries with pros and cons of each.
@hobotech I would like to see you make a video on the ways to ground solar generators in different situations. Like using them in Rvs and outdoors if needed. Thanks.
Thank you!

Great Series.
Now i know everything.
Jus wish i could remember.
Still a tinkering.

@@HOBOTECH thanks, that's the level of detail I was looking for, much appreciated!
Hey Professor. Can you comment on bonded, grounding and floating grounds on “solar” generators AC circuits in you practical way. Great channel. Thx.

Can't wait for you to do a review on ecoflo's power hat
Why should I review it
Oh Hai Doc, need review/testing of new ecoflow products. Thx!
Good basics coverage.
It's 22c/kWh down here in Pueblo. Up in Denver it's only 14c.
Trying to get solar, but the company is slow walking me. Don't wanna get too grumpy with them or they'll make a 'mistake' on the install and suddenly I need a new roof. :(

Paying 40 cents kwh in the northwest territories. Plus extra. 85 cents/ my monthly usage July 327=$142.04

Can you hook a solar panel directly into a battery or do you need something in between ❓❓❓
Sorry if this is in the wrong place. Will the 12v/24v Lead-acid Battery Charging Cable also work the same on LiFePO battery terminals? Will really appreciate if someone knows the answer. Thanks
Good day sir? Hope you can help with have a bluetti 150 that set with low battery now won't take a charge
Its dead. You need to replace it. Bluetti 150 is 5 years old now.
@HOBOTECH I don't think it's but couple years old used of Facebook
@HOBOTECH not completely dead very low
@HOBOTECH ty for responding appreciate your valuable time
Do the clothes make the man? Yes.

It's fine to do but you lose 10-15% from each inverter in the chain.
Do devices draw more current as battery gets low? I'm trying to understand.. If I use 1200W coffee pot and my battery has gotten to half of its capacity.. So, the voltage has dropped, does the coffee pot increase current to get its 1200W? And I can ultimately fry it when the battery is almost completely drained?

I mean now the pressure/push force pushing the same 40A is ten times as less. So less (friction/resistance) and also less power travelling through a conductor.. Can I use #14?
You need to watch all 3 videos. I go into detail about cable choice. But yes amps increase as voltage decreases but it's minor on a lithium battery.
Watt are you talking about?!
What if you have a battery that is a 12.8v LiFePo4 battery that is a 200ah but a 100amp charge/discharge rating 2560Wh rating. How does that work?
200Ah is the capacity. 100A is the max rate of charge/discharge.
I have a question about a Jackery solar generator. Can you plug in two different sources to the input of a Jackery? e.g. 12 v accessory from a car and a solar panel. All Hail Odin.

Exactly. This is a beginner video. I may do an intermediate level eventually.
Watt is this all about? Watch and learn!
I dig this channel.
Hope I meet up with all you guys. Maybe Quartzsite this year.

“I see you’re still working with polymers.”
When do we learn about EPS conduits?
My son, who lives in Quebec, pays less than 6 cents per kW.
Hobo lol
Watts up
Far out
Great job 1:24
hi i bought a battery off amazon it was the lowestprised lifepro battery i could find couldnt find any reviews on it has 12.8v 100am hours the name brand was ingeosolly.12.8volts
I bought it for the price bought alligator clips for it to in cas of power outagage to slow harge my Bluettie 180. It is slow charges at about 100 what hours can you review this?
ty Billly B. i bought it a while ago but never have seen a review. thanks. Billy Barnes
