    The only issue with 48v is usually the initial upfront cost . Unless id you building 12v or 24v system comparable to 48v size wise . The 48v will be cheaper. The disadvantage of 48V u mentioned only applys if you using high PV mppts like 500V . I've seen people build 48V system with a victron 150V 35A controller with only 2 panels in series

      @texasprepperprojects check out Brad Cagle channel, he built a small 48V system using a victron 100/20 charge controller , victron 1200W inverter and a Litime 48V 60Ah battery charging with 4 100w solar panels in series . My point here is u can build a 48V system which doesn't require 100-120 minimum. Yes it works better with 100V and above but it's not a requirement unless if you using those high voltage all in one systems.

    It seems to me that the "120V minimum" for charging a 48V battery is a specific limitation to the that specific EG4 charge controller (designed for large solar panel installs).
    Controllers from other brands for 48V batteries (Rich Solar RS-MPPT60 or Victron MPPT 100/20-48V) mention "battery voltage +2V" or "Battery Voltage +5V" in their manuals. Elsewhare I've read that it's approx. 20-30% above the battery voltage for MPPT chargers to work (e.g. 60V minimum PV input for a 48V battery)

    • @texasprepperprojects

  • @shelley131
    @shelley131 4 місяці тому +2

    Glad you mentioned the EG4. I unfortunately went that route without realizing I did not have enough solar input to start charging with solar. I did find a work around and ordered a victron 100/20 smart solar charge controller that I will use to connect straight to the battery only to trickle charge with my 220 bifacial panels from ecoflow. This unit allows me to select 12V through 48V. Since solar is free I plan to daisy chain my ecoflow 2000 to charge it that way through the inverter if need be. Not efficient but I'm learning. All this is new to me and you explain things well. Eventually I want to do another project similar to yours. Thanks for posting.

    I agree. 48v systems require too much panel voltage for a small backup system. 12 or 24v systems have less arcing problems and safer to work with from my understanding. My fridge and furnace blower surge to at least 1500 watts. So largest inverter I need is 2,000 watts which is just fine for a 12v system in my research. I might go with a 24v system just for the fridge and furnace if my delta 2 ever poops out. I'm working on a 12v dolly system as well and will have lots of usb devices like aa battery chargers and such. I'm also going to use a relay with a piezo buzzer to go off when the load terminals on the scc shut off as a battery monitor.

    That’s crazy the difference in the amount of solar panels you would need to run the 48 volt as opposed to the 12 and 24 volt.. does the 24 volt require more panels then the 12? I was hoping to just have a little cart that I could pull into the woods with me or my backyard for yard wordk etc. to run like a sawall or skillsaw or angle grinder and tools like that, or even maybe for the potential to run a small space heater in a garage for an hour or two once in a while. But at the same time I need it to be fairly portable and the least amount of hassle in terms of setting up the panels. Simply put I am a very “plug and play” type of folk and I like simple and efficient. But I have watched a bunch of prowes videos and he said that it would be a waste of money to buy the little jackery or Bluetti power bank and panels considering how much cheaper and more power you can get with these DIY carts. Thanks for replying sir you make your videos very easy to understand

    • @texasprepperprojects
      @texasprepperprojects  3 місяці тому +1

      don't bother with the space heater. Use a Mr Buddy Propane heater instead. I'd personally buy a 24v, 100 or 200 amp hour battery and 24v inverter. You can pull more power, more easily. Just make sure you 're getting at least 30v of solar into it, which is easy if you buy a used residential panel off of CL.

    Since my van camper is 120v (a/c. & microwave) and 12v for everything else I need to supply 12v. This means I’ll have to use step down transformers! How much wattage loss would I have by adding the step downs, for each step down transformer. If it is very much larger 100% pure copper wires may be a better for my application.

  • @WayneTheSeine
    @WayneTheSeine 2 місяці тому +1

    Excellent explanation of the differences in voltages. I have to rethink my setup. It is presently 12V but can easily be made 24V. I would just have to buy a new inverter. The current difference is staggering. It will cut the total amp-hour capacity by half, though, correct? I assume a 24V system will double the amps you can pull off a 100 Ah BMS, which is a huge plus. With my Starlink mobile system, I am running it straight off a 12V LifePo 100 Ah but kicking it up to 24V with a Buck/Boost. Although Starlink says it will run on 12v, it won't. I expected to encounter heat with the buck/boost, but it didn't get warm. With a 24V system, I could run it straight off the 24V batteries. Great presentation.

    • @texasprepperprojects
      @texasprepperprojects  2 місяці тому +2

      So if you have two, 12v 100 amp hour batteries in parallel, it becomes 12v at 200 amp hours or 2,580 watt hours. If you put those batteries in series, then it's 24v at 100 amp hours, but it's still 2580 watt hours. You haven't changed the capacity, just the voltage. If your starlink is 24v, then you could power it straight off of that pack. The two main advantages to 24v is 1: lower amperages so smaller wires and 2: You can put more total solar wattage into it. By using a higher voltage, you can get more total solar power into it for the same amount of money. Check out my video on the LiTime solar charge controller. ua-cam.com/video/syrnCSMjFhI/v-deo.html . Yes, it does mean you have to buy a new inverter. I use Giandel who makes a 24v.. amzn.to/40zjOAl

    Most 12v compressor refrigerators can be switched to run on 24v.
    For system design, I think 12v is fine as long as you are normally under 1500w or so, and don't need to surge over 2000w. Double those numbers for a 24v system (3000w/4000w). If more than that, go 48v. Maybe someday we'll start seeing higher voltage than 48v systems readily available for DIY.

    I subscribed with a like. It was good to see that you hooked up a 24 volt system. I been thinking on doing that for a good while and you were spot on at explaining about using a smaller gauge wire for the 24 volt system. I am glad you mention that most if not all charge controllers can be bumped up to 24 volts. There are charge controllers (that also includes PWMs) that can charge a 48 volt battery bank and 150 volts from the solar panels. Will Prose has a recent video warning of the dangers of hooking up solar panels above 50 volts when wiring them in series. A person has to know what they are doing when wiring in series otherwise they risk electrocution. That is why I use series and parallel together with two PWMs which can handle 55 volts from the solar panels. Many YT channels would have people believe PWMs are junk. From my observations and using a multi-meter, the voltage and amps start rising after first light and increases during the day to the programmed voltage. In other words, the batteries are being charge beginning at first light. Of course, an MPPT or multiple MPPTs should be used on large systems to maximize the solar input. Furthermore, I have wind and solar on a different system. Wind power is a complicated subject and more expensive than solar but great in using off grid with solar. However, I am not off grid. It's not possible where I live and this would be true for a lot of households.

      In this case wattage is not relevant. That 435 watt panel is PROBABLY 37 Volts at 15 amps or so. I have 12 volt 200 watt panels and I have 37 volt 250 watt panels. You have to read the specs of your panels and your charge controller very carefully. The best of both is high voltage and high current, typically residential panels are the best mix

      Always go with a low frequency inverter, not those cheap Chinese high frequency ones like he is showing you, the battery is fine altho there are cheaper ones just as good. So do you need 200amp bms on your battery? 1500w ÷ 24v = 62.5 amps so you only need 100 amp BMS on the battery. Let's say later you want to run a 3000w inverter, add another battery with a 100amp bms, now you have 2 x 100amp bms batteries, drawing 3000w ÷24 v = 125 amps, being pulled from 2 100amp bms s sharing the 125 amp load, basically 62.5 amps each, if wired correctly, not wired correctly 1 battery will pull more than the other

      You have inverter losses to deal with also. If you go to 1:52 you'll see that 1,000w is pulling 75 amps from the battery. So, I'm slightly off, but you wouldn't want to run something right up to the 100 amp limit of the BMS 24x7. So, my comment about 1,000w is me errroring on the side of caution and rounding down for safety and inverter limits. Most BMS can spike to 150 or 200 amps, so you CAN run a couple thousand watts, but not for very long
