What can run on an inverter and for how long? 

I don’t have it any more, my apologies.

Watch video take a snapshot

Take a fuckin’ screenshot you fuckin’ BOOMER

@@i13lade haha thats gold lol

Yes. It should be obvious from the math on the spreadsheet.

Actually, the spreadsheet only states "Run Time with 100 amp hour battery bank". The spreadsheet does not explain whether you have four 12v 100ah batts, eight 6v 100ah, or four 12v 25ah batts (which you and I know can not produce 48v with 100ah although people new to this type of power system would not). I am not trying to be rude or disrespectful. I just think it would be good for folks new to this type of power system if it were explained a little more obviously. I know you mention briefly in your commentary that it would take a lot of batteries but I have to disagree, this fact is NOT obvious from the math to someone who does NOT already know this. The spreadsheet assumes the reader knows what must be done to keep a battery bank's amp hours at different voltage configurations. If someone were using three 8v 100ah batteries in series to get to 24v they may think they have increased their ah to 300 when they still only have 100. Your spread sheet only explains the amp usage at different voltages. Again, not trying to put you down. I thank you for sharing your knowledge with others. I have learned a lot from folks like you about other things I didn't know about. I am just trying to help you help others even more.

I agree. The OP needs to check his formulas at and upto F12:F15. If an appliance draws a constant 1000 watts and the battery is 100 Amp hours I fail to see why these numbers would not all be the same.

make a video!

@@FernbarkFrist CAN YOU RUN 3 BATTERIES IN SERIES AND 4 BATTERIES IN PARAELL AND BALANCE AMPS OUT WITH VOLTS?

This is an interesting problem. My full sized fridge averages between 1.5 and 2 kilowatt hours per day. You will need enough solar input to fill that need, plus whatever else you want to run. There are a ton of variables to take into account. I would suggest going to the Arizona Wind and Solar forum, it is very likely some one has asked a similar question that you could get some guidance from. If this is not going to be a full time solution, I would consider looking into something like the Eco-flow Delta series, or one of the big units from Bluetti. It would be an all in one solution, and you would just have to hook the panels to them.

You're welcome!

SilentDeath002 Line loss might account for some of it, but I believe I have some shading issues also. The roof top air conditioner is shading one of my panels pretty good for part of the day and I have an antenna I need to take down that shades somewhat also.

It is not a practical solution.

I have a 32" monitor and my Xbox one going to a 750w

Correct

I don't think I still have them. You can go to almost any solar power forum and get them though.

Smart

You are right, cooling units are brutal on solar systems. Thanks for watching.

The battery voltage will drop as you pull amps from the battery. Depending on your inverter, most have a low voltage sensor that will turn the inverter off before completely draining the battery. Your battery will still be pretty shot at that point. You do not want to make a habit of that. I very much recommend you never try to run an A/C on batteries unless you have a huge system, which you probably won't if you are using it on a camper. I ran mine and got high amp and high temp alarms on the inverter. If you really want to learn more, I recommend going to a solar power forum and read the new user threads where this is all explained in detail.

You could do that I suppose.

It isn't the inverter, it is your batteries you need to worry about. If you want to power it for 8 hours, you need 6000 watt hours of usable capacity.

Depends on the battery, how long you run the projector, and how much power the projector uses, and how much power the inverter uses to convert the battery power to AC power.

Sorry, I can't. but most solar power forums have a similar one that you can download and use.

SilentDeath002 I had used 10 awg as well, since that is the same size as the wire that comes from the panel. I have since put in 6 awg, but have not seen any improvement in wattage. I also expect since my panels are flat and not angled towards the sun, that is also an inefficiency. It all adds up (subtracts down?).

You can run a laptop

Higher voltage allows the use of thinner wires, which are cheaper and easier to run.

You will need an inverter that can produce 1500 watts or greater.

@@FernbarkFrist thanks for the info

No, sorry

Going to say no. Technically you could get something jump the voltage from 12 to 48, but it is going to drain the battery in a hurry, depending on which battery you have and how big the load is.

assuming 230Volts - with a safe minimum of 650 Ah batteries at 24v (and if you want to be battery friendly double that) and 2000 Watts of solar panels.

You would have to see how much surge that speaker has. It probably would, but it is going to drain your battery pretty quickly.

Unless you custom wired the cig lighter, you can not pull that much power without smoking the wiring going to the socket or more likely popping a fuse.

Car battery is a bank of one battery, with a very low storage capacity (most likely). You can run the car to supplement the power, but that is generally not an ideal situation, and I don't recommend doing it for very long.

I seriously have no idea what your question is or I would try to answer it.

My truck need to plug it in power i can't start it in the morning. I was thinking to get a power inverters so I can hook it up to my truck batteries and connect the engine heater to it. So I got to run up to 3000 watt. For only 10 minutes the batteries losing its charge so this thing it doesn't work. I was thinking to find another idea to connect the heater I make the engine warm and then maybe I can start my truck

my car block heater is obviously less than 1500 watts because it run on a standard AC extension cord. It never blew the fuse so we will suppose it is 1000 watt of power to simplify the math. 1000 watt x 10min/60min= 166 watt-hours, most AGM battery are on the order of 100 amp-hour x 12 volts= 1200 watt-hour and you can use only 50%= 600 watt hours so your house battery OR start battery if your start battery is AGM, can easily give away 166 watt hour to heat your engine and will be only 166 / 1200 depleted, this correspond to 14% so it leave you with 86% full charge ( i am not familiar with using standard cranking start battery for this application because they are not deep cycle, only marine are deep cycle. Standard batteries are for start only and this is why small Honda Civic batteries don't last many years, they are routinely overloaded. So you can do it and the next time you will buy an AGM or marine deep cycle) and i can bet your truck will start, but you will have to travel enough to recharge it, not just a little trip to the neighbour store. The good new is that you block heater is a purely resistive load so this is perfect for a very cheap modified sinus wave inverter we can find everywhere like in Canadian Tire in my town. You have to buy a unit with at least 1500 watt of power so your 2000 watt device is perfect and you have a margin of security, these device can become very hot and you don't want that. If you can, it is better to have them mounted vertically for the heat dissipation by natural convection. We see many you-tuber burning their inverter and having to change it, one was in the ocean when they burn it if i remember correctly. Modern inverter have one or two tiny computer fan so make sure your inverter is installed in a well ventilated place, if not you will do like many you-tuber, who burn their expensive Danfoss 12 volt compressor because of not enough ventilation.

Omar nissan. What is your motor. What temp does it go down to. Maybe get an inverter generator. My 97 7.3 started just fine this winter in mi which got to minus 20 ish

Going to wipe out a battery bank fast.

That is funny. It always cracks me up too, when I see YT recommend I watch my own videos.

Maybe, do the math and figure it out. It should have the watts it uses ( or amps then multiply by 120). If your inverter has the capacity, you are gold.

All inverters are different. That would be a tough list.

You need a lot of solar to run a big fridge.

It's not a waste of time at all

Please read the pinned comment.

The inverter will draw power. You will have to look at each inverter to see what it's no load draw is. They will all be a little different. Usually the rated draw is pretty close, but assume it will be up to ten watts more than what they claim.

Well, CCA is a measure of the Cold Cranking Amps the battery has, and not an actual measure of the battery's capacity. You are looking for a number followed by "ah" after it. If I had to guess what the problem is, your inverter is probably over heating and turning itself off, or the wires going to the inverter are too small and the inverter is sensing a low voltage (causing it to turn off)

@@FernbarkFrist amp hours... but was the 75w inverter not enough to power the lamp bulb; it's a CFL bulb so it shouldnt draw a lot right?

@@dadaUnts It should have enough power. I am not there to look at it, and I don't want to trouble shoot it long distance. There are many things that can cause your system not to work.

@@FernbarkFrist ok so I also took a look at the lamp; 75w, 120volt 60hz, sorry for asking too much but I just need to know, I really appreciate this, thanks

Depends on what the surge for the Vac is. If the surge is over 2000 watts, then it will never work. Plus, the surge doesn't have to last long, I had an inverter that would not run a fridge because a split second of surge kept popping it.

How do I fig out the surge

www.globalindustrial.com/p/janitorial-maintenance/floor-care/vacuums-wet-dry/55-gallon-3-0-peak-hp-2-stage-wet-dry-vacuum?infoParam.campaignId=T9F&gclid=CjwKCAjw88v3BRBFEiwApwLevaq2HyDv-j-4M_mQXL5Pvl_yY2myahBVl9-0UyFKHzen-2d2nl4CFhoCpe4QAvD_BwE

you have to use an amp meter and closely watch as the surge is a split second

Google "wire size chart". Use that to determine the wire size.

Sure speaker wires would be perfect, infact you can try using a telephone extension cable, smaller the wire, the better. Maybe you can also try 2 drinking straws

Lol

Glad to have helped. Once you get used to the math, it is pretty easy.

Weird. It should be the same wattage input. The amps and volts will be different, but the wattage should be the same.

@@FernbarkFrist Its the max wattage input, not the actual. A 30 amp controller will take up to 400W at 12V or 800W at 24V. Panel would be 400W regardless. Output amperage to a 24V battery would instead be around 15 amps.

I would not try to run AC on the car alternator. Depending on the chemistry of your batteries, you will won't get 2.4 hours of use either. You don't want to fully drain them down.

correct

First, your math is wrong. Volts x Amps = Watts And I have been using Trojan GC6 batteries for years. Also, now that LiPo batteries are cheaper, they are the standard for batteries. I will never buy another 6v battery again.

I should have said amps, instead of power consumption

You should get the same run time if the batteries are the same chemistry and have the same Watt hours. Also keep in mind that the Ego batteries are LiPo and can drain down 80% and probably your solar set up has lead acid, and that you probably only drain down about 30-50% of the batteries capacity which shortens the amount of run time.

Thanks for watching.

Yes

Depends on how many amps your alternator is generating. My 13.5K ac used close to 400 amps on start up. It didn't last long, but that is a big pull of power.

Since I have no idea what the load for a well pump is, I cannot answer that question.

The reality is that most people have 12v inverters, and some have 24v. Hardly anyone has 48. If you are serious about solar and inverters, you are probably already familiar with the math needed and are willing to invest in a battery bank to support 48v operation. Most people are not.

Batteries without a load on them read higher voltage than they do as soon as you put a load on, so a drop in voltage is normal. Take your battery to an auto parts place and ask them to test it if you want to make sure it is not defective.

You will need many more panels. They never work at 100% efficiency and you also have to account for the surge when the unit starts.

It's pretty much just watts=volts * amps I wrote this at least two years ago. Not even sure I still have the spread sheet. IF you go to any website selling solar gear, they will have a similar spread sheet ready for you to use. I think Arizona Wind and Solar has a pretty good one.

Fernbark Frist Great feedback, Thank you! :)

@@milro5011 ACCEPT THE FEEDBACK . WILL YOU PLEASE BRING UP NOT ACCEPTING FEEDBACK IN EVALUATIONS PLEASE SIR. LOL GOOD

@@FernbarkFrist I AM A DUMBASS. I AM NEW AND IS GETTING A 24 FOOT CAMPER TRAILER NO VEHICLE THOUGH. HOW MICH IS IT FOR ME TO BUY A START UP KIT? I REPEAT. I AM A DUMBASS. I WANT MY TRAILER OFF GRID.

Depends on how many cups you are making in that time. But I would guess it would not last for too long.

There are far too many variables for me to even guess. You will have to do the math yourself with the equipment on hand to calculate it correctly.

yes , with lots of AH to spare

Mathematically, Amps= Watts/volts....so if you are using 1 amp @ 120vAC, it is 10 amps at 12vDC.

That’s also known as a drill-less cord.

I have solar panels that feed batteries through a charge controller before it gets to the inverter. No alternator in my system. But you are correct about wire size. If you have a larger inverter, you will need the correct size cables.

They are all pretty quiet. The bigger ones might have a little fan noise (about the same as a computer). I would need to know all the power requirements of your gear you want to run to tell you what size to get. The whole purpose of this video was to show you how to figure it out yourself.

Just learn the math and you can answer your own question. I show the math in the video, and then you can apply it to your own devices. I show the products I have as examples of how you can figure out what you need using your devices.

You will need an inverter that puts out 240 volts.

You sure can upgrade it. It only takes money.

The higher voltage will be better because you will have less amp draw, but you still will not get much run time depending on the tools you are operating ( say a compressor or a big saw)

no

Those don't actually work. I have tried them.
