    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.

    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.

      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.

  • @JD-rp1fx
    @JD-rp1fx 6 місяців тому

    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.

      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.

    • @cleversolarpower
      @cleversolarpower  9 місяців тому +1

      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.

  • @Abiola-y3z
    @Abiola-y3z 10 місяців тому

    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.

    • @cleversolarpower
      @cleversolarpower  10 місяців тому +1

      83A x 1.11 (efficiency of inverter) = 92A. Yes, the BMS will get warm, but that's what it's rated for.

    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.

      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.

      A "100 Ah" Lead Acid Flooded Deep Cycle Battery (Trojan SCS Series) is "Rated" at 20 Hours, meaning a "5 Amp Load" (20 Hours x 5A = 100 Ah)

    • @robertweekley5926
      @robertweekley5926 10 місяців тому

      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!

      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.

      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.
