Thank you for simplifying and sharing your knowledge. As a direct result of your previous video, I have abandoned my Lead Acid, and moved to a Lithium to power my 1000w Inverter. It works perfectly. All I need now is for spring sunshine to come 🤣
Ok, I'm new to inverter, solar-powered, and batteries. Your video explained it well. I WAS going to get 3k watt inverter with just one LiFePO4, rated at 100a. I know now that I would need at least 3 100amp batteries to work with a 3k w inveter.
To get 1000W from the AC output of the inverter, the input power to the inverter will be higher than 1000W due to the inverter efficiency, 80% is typical, so the current draw from the battery will be 83A/0.8 = 103A.
Correct, when sizing wires and cables we use a 1.25 factor to account for this. I didn't include it in this video because it would make it more complicated.
Hello, thank you for excellent and outstanding videos. I have a question, I have 4 100 Amps AGM batteries on my boat. I also have a Victron MultiPlus 2000VA and Digital Multi Control 200/200A GX. From your video, it seems that I will need an additional 400 Amps to cope with my 2000w inverter - right? My question is, until I do add the needed batteries can I still use 1000 w appliances in the current setup without the overheating or any other risks?
IF i only charge my lipo4 12v 100ah battery with solar panels i do not need the invertor right? for i just want to only charge the battery for augmenting my Bluetti EB3A 268Ahcapacity and have 1080 usable Wh with my EB3A battery. is this correct? or am i mistaking? 1080+268= approx 1300Wh. instead of just the 268 watts. since the EB3A has a charge controller mppt integrated.
I like your video but I can't figure out how many batterys I need. I want to power a computer pulling 1500w at the wall at night. If I have a solar pannel charging the batterys during the day? Is it even posible to power for that amount of time?
Thanks, I feel like repeating myself when I do that video. It's the same principle over again. 2000W on 24 will draw 83A. Lead acid needs to be 24v 400ah, and lithium 24v 100ah.
Is that the required battery sizes if you run the inverter at max power? If your load is only say 200A (a fridge and some lights) you won't place a big draw on the battery, mostly inverter on idle.
very great video !!! at 2:42 what should we concern if we use 12V , 100ah lithium x 2 pleazzze ? or should it be better to use 12V 200ah ? cant figure it out that part , been watching this over 5 times now 😂
You can have a 12V 200Ah battery. You will require less wires which is good. You still need two of them in parallel to make 12V 400Ah. But if you are buying new batteries i recommend getting lithium (lifepo4). they are cheaper as i have analyzed in my video about lead-acid vs lithium.
I just bought A 12v 4000w power inverter im planning to parrallel 6 lead acid batteries that i have ,what busbar do i need ? I have an RV truck ,what are you recomendations?
Thanks for the video. As a result I want to replace both my deep cycle 100amp lead acid batteries with 2 Lithium 100ah batteries. My inverter is a Sensata Technologies CSW1012 1000W Inverter. Will this set up work for my situation?
Thank you very much for the video, I am learning a lot, but it is not clear to me if a 200Ah (lithium) battery would be better than a 100Ah? Would it be more efficient?
Having a larger battery will put less stress on the battery. One battery will draw 85A while a second battery in parallel will only draw 43A per battery. So you put less stress on the battery, leading to a longer lifespan.
Your videos are so succinct and serve as refresher for me as an experienced Solar PV Professional. However, this particular video needs reveal. For example, if an inverter is rated 12V/1000W (assuming 100% efficiency), it means it can supply max. 83A. Then a typical Lithium battery rated 12V/100AH at 1 C rate will draw maximum of 100A. The system will definitely overheat because what is required for the battery charging 100A is higher than what the inverter can supply which is 83A at 100% efficiency. Thanks.
I have a super budget cheap universal brand 100 amp hour capacity 12 volt sealed agm lead acid battery paired with a 1000 watt pure sinewave inverter and it works beautifully. No problems. Never took the battery below 80% depth of discharge. and it handles loads like window air conditioners. vacuum cleaners. computers. and more. with no problems. powering it for a few hours. Doesn't get hot. Voltage drop is not a problem. I used thick 1/0 awg gauge cable so even under the load of a full size window air conditioner it powers it like it's not even there. It is about 3 years old and still works like new. I respect the batteries maximum capabilities by checking the manufacturers specifications on it. and it is fully capable of handling anything I throw at it when properly set up and used correctly. I use it as a backup emergency power generator setup. where it is kept charged and maintained when not in use. and fully charged and ready for use if there is a power outage or other emergency where we need significant portable power. it is very cheap and budget but works great.
What if I’m using it on my truck a 1000w inverter and I’m connected to my alternator my inverter has 6 fuses on it. What size wire should I use? And I will be using my inverter only when my truck is running and the distance from alternator and the inverter is 6ft. So what size wire would I need?
Can you tell me how many batteries I need for a 8000 watt inverter? I tried to start up a shallow well 110 water pump but it would not work. I only have 4 rv lead acid batteries in parallel. Do I need more? Thank you.
You can repeat the calculations shown in this video to your own system. You will definitely need more than 4 lead acid batteries. Why did you even get a 8000W 12V inverter. Bigger is not better.
Hi I have a question A 2,500 pure inverter. how many 100 amp lifepo4 batteries will I need. otherwise a 2000 watt inverter. and a 3000 w inverter how many batteries.
Ok, I'll start again. I have 4 x 12V x 300W In Series Parallel Solar Panels feeding into a Vevor 12V 60A Controller, feeding into 4x 12V x 120Ahr Batteries, In Series Parallel configuration, giving me 24V 240Ahr. The Batteries feed into a 12000/6000W Inverter. Will only having the 4 x 120Ah in Series Parallel create a problem, or do you think that will work ok?
6000W/24V=250A, the max your batteries can deliver is 240A in a 2S2P configuration. So it will work. However, you should have better used a 48V system. Check my video 12,24 or 48V battery system.
I like your videos. I just received your free diadgrams and am working my way through them. On page 5 of the free diagrams you say a lithium battery can provide a current of 0.5C. But at 2:10 in this video you say a lithium battery can provide 1C. Can you please clarify?
watching your video and doing some math (hopefully correctly lol) a 2000W inverter with my 2 24V Battery 100AH should be fine (1920 W) . Is this correct ?
To get a Durable Setup, if you need to pull 100 Amps just divide 100 by 5 to get your battery count! (100/5=20) So that means 20 in Parallel *For a 12V Inverter*, or 4 in Series x 5 in Parallel if you use a 48V inverter. So 2 in Series x 10 in Parallel, for a 24V Inverter!
Lithium cell banks do not have a resting voltage of 12v. It's always just above or just below 12v. So utilizing them in a 12v system is not optimal. Use this information in your planning.
I have discussed that in my video about a 3000W inverter. If you have lead acid, you still need 4 in parallel to respect the C-rate. If you want a 24V system, then you need 8 batteries in a 4S2P configuration.
@@mynameisprivate158 Your current will be 166A, which in my opinion is too much. It will work, but not as good as a 24V or even 48V system. I have a video about that upcoming.
I have been using 12v 150ah lead acid battery on my 1000w inverter, and the results after 6 months, now, the battery drained in 30 minutes in 200w load.
0.5h*200W=100Wh. Your battery can deliver 12V*150Ah*0.5=900Wh. So if the battery only delivers 100Wh while it should be 900Wh, then your battery is dead.
What bothers me here is that in all the calculations how can one tells factors like How long will the Inverter supply the load capacity How long the battery will take before it is full and of course how long before the battery charge controller or inverter shutdown when i reach my targeted depth of discharge. Please help

Im guessing you know better.. so... Why would you say lead acid is 0,2c and lithium 1c? My old lead is 0,33c but higher is quite common. I often run into 0,5c while browsing. Also lithium goes all the way up to 100c and probably higher. Some are lower than 1c thou. Most of my own are 3-5c. I'm just curious why you say 0,2 & 1c.. why not just teach people to examine their bats or examine what to buy.
Checkout the data-sheet of the battery. Most lead acids are tested at C20 which is 0.2C. that is then the capacity. You can discharge quicker at a higher C rate, but then the capacity is reduced. Look at trojan battery data-sheet which shows it very clearly. Lifepo4 batteries are discharged at 1c and then the capacity is based on that discharge rate. Check my video about C rate.
Cmon, you gonna deep discharge the batteries? 😅😅 The lead batteries are the worst, you can only discharge it for 25%, the rest of it 75% must remain in the battery! They are very inefficient! The Lithium has its own quirks of course!

It's best to use a 48V system for home applications. 12 or 24V for mobile. Don't rely on the surge protection of the inverter, this will probably not be correct. 900W/12V=75A*1.25=93A. At least a 100Ah battery.
@@hotshotter4500your fridge consumes 500W/12V=42A. What kind of monster fridge it is, but anyway. 200Ah/42A=5 hours. But remember that fridge works in cycles. You can multiply that time by 3, I think.

@@davef.2329 Hey whatever works. I'm already running the fridge, I like to turn the diesel heater on in the morning, and maybe nuke a pastry with some butter to have with my coffee.. 1000 just won't cut it. Some of that stuff is 12V, but still....
I have a 2000w continuous/ 4000surge power inverter and I am not sure what battery I need and if I need two of them . Please help ?! 🫠
I’m trying to power this portable air conditioner 900w 8,000BTU
It's best to use a 48V system for home applications. 12 or 24V for mobile. Don't rely on the surge protection of the inverter, this will probably not be correct. 900W/12V=75A*1.25=93A. At least a 100Ah battery.
@@cleversolarpowerf I buy a 2000 inverter and a 200ah lithium battery how long should I expect it to run a refrigerator that draws 500w?
@@hotshotter4500your fridge consumes 500W/12V=42A. What kind of monster fridge it is, but anyway. 200Ah/42A=5 hours. But remember that fridge works in cycles. You can multiply that time by 3, I think.
