Victron Phoenix 12V 1200VA Inverter: cleversolarpower.com/go/CC12V...
In this video, I talk about what size inverter for 100Ah battery. Join me as I break down the complexities and provide straightforward answers to crucial questions like what size inverter for a 100Ah battery and how to size a battery for your inverter.
I'll cover everything from calculating the ideal inverter for both lithium and lead-acid batteries to exploring different voltages and capacities. Plus, I'll show you how to determine how long a 12V 100Ah can power a 1000W load.
When it comes to lithium batteries, I recommend sticking to a maximum of 1000W, while for lead-acid batteries, aiming for around 200W per 100Ah battery is ideal. By understanding these key principles, you'll be able to optimize your off-grid solar power system for maximum efficiency and longevity.
And don't worry-I won't leave you hanging when it comes to practical applications. I'll provide real-world examples and walk you through the calculations step by step, ensuring you have all the information you need to make informed decisions for your solar setup.
But that's not all. I'll also tackle the important question of standby power consumption and recommend the top-notch Victron phoenix inverter lineup, known for its superior performance and energy efficiency. - แนวปฏิบัติและการใช้ชีวิต

Great Video. Informative and straight to the point. Well Done Mate 🤙🏻
I try to be straight to the point without any fluff 😉 thanks!
Excellent as always!
Good Evening ! Thank You. TAKE CARE..
There is nothing wrong with using an oversized inverter. One reason would be to allow for future expansion. Just don't draw more power than your current battery system can handle.
I agree, it depends on the load.
Good info. There is no one size fits all. Need to pick each component based on the entire system.
Hey mate how have u been?. Hope you and your family are well
Great video, keep it up
Thanks for sharing.
Thankyou sir
Hello from South Carolina
thank you for the presented material. recently I heard that photovoltaic panels can be equipped with optimizers. what they are and if they can be used in any situation.
Unless you have shade, I don't recommend using optimizers because the cost will outweigh the benefits. I made a video about 'different kinds of inverters' where i briefly touch upon these and microinverters. Check it out on my channel page.
@@cleversolarpower ok , thank you !
I have 4x 48v 100ah rack batteries and a 5600 watt inverter.. I'll be buying another 4x batteries and also updating the inverter to 8 or 10kw. That's hybrid inverter/charger.. And 12-14 270w panels..
I use MPP inverter/chargers. They are good but have a higher standby current draw
cool
I have two 12v 120ah lifepo4 on 3000watt 24v inverter. My charge controller shutdown. I also have four 250 watt panels connected in parallel.
I wish I understood this stuff better 😕 I will just listen.
Take notes 😉
I've been using four sealed lead acid batteries with a 2000 watt 12V inverter powering washing machine that peak draw about 1800 watts. Been in service over one year now. I do 2-3 loads per week.
So I'm apparently way under sized my battery bank??
Thank you for good informational video.
no. How deeply do your batteries become discharged (end voltage)
So I had to check again this AM pulls about 8.5 AMPS max load. Batteries lowest I've seen was like 11.4 volts after doing consecutive loads. And meter showed charge level only hit 50% briefly.
@@chadrogers3161 I don't agree with the premise of this video, but it isn't mine. For longer life 11.7 volts after resting is the _minimum_ (the less discharged, the better - recharge sooner). So S.O.C. is best to 50% of 12.7 to ? as rated by the Mfg. Other than that, you appear to be just fine, unless you _need_ longer operation from the battery. Carry on.
@@jamesalles139 yeah they are connected to three 100 watt solar panels so plenty of time in between uses to recharge.
@@chadrogers3161 That all seems right-sized to me. expect performance to suffer after 3-5 years
I am only a beginner.I have a 25w panel and a 7 ah LA battery.
Very informative. I have a 100Ah AGM Lead Acid and a 120Ah AGM lead Acid batteries. My Invertor (MUST Invertor) is rated as 12V/1000W. I have an MPPT charge Controller rated as 150 MaxPVoc. What will be my set up?
Connecting the batteries in parallel is best. However, that's insufficient to run a full 1,000W load on it. It will work, but as I said in the video, it's not healthy for your battery.
I have a 1000 watt inverter a 555 watt panel and a 102 amph battrie. Runs a fridge and wifi on it day and night.
Hi, Nick. I just came across your channel the other day and have learned a lot already after watching just a few of you tutorials. One thing that I learned... I have been making some very wrong assumptions about size and capacity. On my RV I currently have 2 - 100W solar panels, 2 -125 AH AGM batteries, all wired in parallel. I have them connected to a 40 amp EPever charge controller and to a 2500 W Sunforce Pure sine wave inverter. Problem... this set up will not run my microwave or coffee maker without tripping the cut-off circuit in the inverter. I have recently acquired two 300 AH Renogy Lifepo4 batteries, not yet installed. Will this solve the issue with tripping the inverter or am I missing something altogether? And do I need to resize my inverter to take the new batteries? Your comment or those from other followers of your channel will be greatly appreciated. Thanks.
Hello Trevor, answered your email.
informative video. I have a question.. I connected 2 solar panels of 100w each , to 3 12V batteries 2 of which have 100Ah each and 1 has 150Ah. I use 1000W inverter. However, the power often goes off at night but sometimes during day time. what could be the reason?
Not enough solar to recharge the batteries. It depends on your load. Make a calculation and see how much you need. Checkout my video about sizing a solar system.
Any free diagram for this?Really interesting.
There are no diagrams for this because it's mostly math. I do have free diagrams, check the link in the description😉

Thanks for the great videos, I'm also using your website links to buy your recomendations on amazon. I currently have the MPP Solar All in one unit: 12v 1000w inverter, 40A solar charge controller, and 20A AC charger. I'm having trouble figuring out how many batteries I can add in parallel. I crrently have a 12v 200AH Li Time battery and want to add a second 12v 200AH Li Time battery. Can my inverter handle that much current? And are the 40A solar charger and 20A charger enough to charge 400ah? I've allready bought the 12V system, and I can't afford to switch to 24V. ;)
More batteries is better (most of the time). You got to see that the system is still properly sized. Batteries should have 3 days of autonomy. So if your daily consumption is 800Wh, then you don't need an extra battery. You can charge the batteries with 2A, the charging current doesn't matter that much, it just impacts charging time.
@@cleversolarpower thanks! Very nice of you to help people out.
@@cleversolarpower one more question, if I add a Li Time 200ah battery with a 100amp BMS, to my existing Li Time 200ah battery, in parallel, do I use a 125amp MRBF fuse on battery #1, and a 250amp MRBF fuse on battery#2? I watched your videos, you said fuse each battery in case of short circuit overload, but still having difficulty understanding fuse sizing when two batteries parallel.
Hi m8.
All fine here but like to ask for your thinking about my coming setup.
Lets start with my needs, no im in the Philippines wery south so its little diffrent.
Main who needs regular power is refigerator for beer and freezer for the bbq.. joke but its the main thing we really need.
Also a few fans running dayly will be needed.
Have some clue about power, ill add 20%
refrigerator 100w freezer 100w, fans and accesory 200w.
Some rarely use of microwave.
Can you give me a thumb what i need ?
My own estimate is as follow.
3x600w panels and 4 batterys for cooling and 2panels + 2 batterys for others separeted.
Seems ok?
Checkout my video about designing an off grid solar system as well as my calculator on my website.
I have a Renogy 2000w Inverter with two Eco-Worthy 12.8v 100Ah lithium batteries in series. Am I properly sized?
2000W/12V=166A/0.9=185A max draw from inverter. A 100Ah battery can deliver 100A, so 100A x 2batteries = 200A. So you are properly sized.
I have a Sungoldpower 4000w 12v inverter/charger in my rv with a LifePo4 12v 300ah battery. Is that too much inverter? I am adding another 12v 300ah LifePo4 battery in parallel for 600ah if that helps.
I don't recommend going over 2200W for a 12V system. Your wires will be costly. Check my video about 12V,24V or 48V battery systems.
I have 3 12V 20Ah LiFe batteries, if paralleled what watt inverter is best? 650W or 600W
You have a 12V 60Ah battery. At 1C, you can pull 60A max. Assuming the BMS is rated at 1C as well. 650W/12V=54A. So you can run a 650W load.
If I have a 180 W inverter for my Travel trailer.How big of a lithium battery can I get to max out that 1800 watt inverter?
Assuming you have a 12V lithium battery, you can draw a max of 100A, that's 12V*100A=1200W max draw from one 12V 100Ah lifepo4 battery.
I have 3-100ah Mighty Max lithium batteries hooked up in series
With what inverter?
@@cleversolarpower I have 2, a 2000W Power Tech-On and a 1200W Victron Phoenix both are 12V I don't have either one maxed out. Thank you for all your info I find it very informative
@@cleversolarpower I have 2 a 12v /2000w Power Tech - On and a Victron 12/1200 Phoenix I like this one a lot. Thank you for all your helpful information.
Thanks for your reply.
Is it possible to run a 2000w inverter on a 100ah battery with a 700w microwave?
No, because the c rate of lithium is 1. You can discharge a max of 100A with the BMS.
24v 200ah load 500w
Very well sized.
How about GEL batteries]
Gel and AGM are in the same category as lead acid.
@@cleversolarpower Aa thanks for claryfiing
Do you mean, brother, that we cannot use more than 40 amps for a 200 amp acid battery? This would be excellent, please.
You can, but it wouldn't be good for your battery or efficiency. 40A is the max you should draw, not what you can draw.
@@cleversolarpower thanx my dear
Even 500watt inverter with a 60watt load can not be connected on lead acid battery 100ah
I assume you are talking about lead-acid? Of course it can. A 500 inverter is not the same as a 500W load. If you have a 60W load, then you get a total of 70W (including 10W of the inverter). Maxing out the inverter is not a good idea (500W) because it will shorten the lifespan of the battery.
I have a 1200watt inverter on a 100ah battery, I will just be careful not to go over 1000.
Yes, otherwise the BMS will shut down. The inverter has inefficiency as well. Usually 90%. So the max you can draw on the AC side is 1080W AC.
