    probably 3-4 hours. The calculation is pretty simple, if you need to run 450w for 12 hours then you need a battery that is 450w x 12 = 5.4Kwh. You probably would want to add a fudge factor of maybe +25% for overhead.

    @@squirrelmasters Pretty much, 12.8v 100ah = 1280wh. Keep in mind the voltage matters, for example a 24v 100ah battery = 2560wh. Now if you had 12x 100ah 12.8v batteries like you said, this would give you a total capacity of 15,360wh. You also might want to consider a higher voltage system. Wire size, and charge controllers get expensive with large 12v systems.

    I've been doing this with my AC200L and my personal PC for a few months. The only issue I've seen is if the AC output is close to the 12A max grid input, it freaks out and turns off the grid. If I don't notice it will then run the battery dead. If I do notice, I have to do a full power cycle to get it to work right but with a load of about 500 watts mining with my 4090 and 7800X3D I usually have no issues. I only run a load that high if I'm mining and running the Midea air conditioner at the same time. Dallas summers are brutal. I might try a firmware update and maybe that fixes my issue.

    Ran a test on our upright freezer. Test lasted 15 hours, stopped it short because I went to bed. When the freezer cycled on it was using approx. 115 watts. Since I didn't have a shunt or a smart battery I used a Govee Smart Plug Pro to track accumulated KWH. This model freezer used 861 watts total in the 15 hour period when I stopped the test. It could have lasted longer. I am only using this Licitti power station when the grid is down, and at night so I don't need to run the gas generator. Charged it with a 30 amp charger and its slow. I have the first model, and the newer box. With the Govee Smart Plug I was able to see the status of the unit while traveling that afternoon. Works for me.

    Put your 4 panels in a 2s2p Configuration. (2 in series, 2 in Parallel) when that shade hits later on in the day half of your (non shadded) array will still get full power. whats the model number of the solar panels? What is the VOC and amps on the back of it?

  • @BradCagle
    @BradCagle3 күн бұрын

    It may not do well in 2s2p. The IMP of the panels is 11.38A, and the max PV amps the power station input can handle is 15A. So in 2s2p it will need to allow over 22A to get the most out of it. This the pain with power stations, you have to run the voltage up as high as possible (while not going over) to fight the input current limits. The other worry is the PV adapter wire supplied by Bluetti looks a bit on the thin side (just checked 14awg, ok for 15amp) , so In the event something shorts internally, and those panels do pump out 22+ amps into that wire because of a short on the other side (short in the power station) might melt something. Thanks

    @@BradCagle I had a situation like you when I was using my AC200p, I could hook up the last panel to the charge enhancer and that would send AC power to the Unit, but these new Bluetti units don't use power bricks anymore. I upgraded to the AC300 and still had that same issue but then I discovered the Bluetti PV step down Module. It allows you to put up to 450volts (i believe, i have to check) into the AC300 and other compatible power stations. It steps down the voltage so you don't have to worry about over paneling. The AC300 combo is dirt these days compared to what I payed for mine

    The only other advice I could give you is to get 2 more of those same panels and put it in a 3s 3p string. have one facing south and the other west or east (whatever is better for you in your location) that way you'll get more coverage throught the day or if you face them all south you'll get those max 15 amps that the power station can accept.

Could use the whole thing just as a cloud buffer and only run the miner when the sun generates enough juice to run the miner otherwise shuts to miner off.

    So I hooked a string inverter (LV-6048) into my main panel. It's a split-phase. This inverter is able to power the whole panel with no problem. I've ran all sorts of equipment such as lights, a TV, video game console, EV Charger, etc. Everything works perfectly. With the panel up and running, I connected my Enphase IQ7 microinverter into the panel hoping it sees LV-6048 power as grid power. Well, surprisingly, it worked! The IQ7 moved from red blinking light to orange. However -- when I put a load on the panel, the IQ7 does NOT contribute in terms of power output. Only LV-6048 power is used. I'm able to confirm this via my clamp meter on the IQ7 cable. LV-6048 is connected into the panel via a 50-AMP double pole breaker. My IQ7 is connected via a 30-AMP double pole breaker. Not sure if that matters?

Also the profitability is very low to non-existent right now for most hardware that is in consumer reach. If you really want to play around, and learn you can grab a fairly recent GPU like a NVidia RTX3070 (there are newer ones available) and use something like nicehash.com. Nicehash has a profitability calculator so you can check if a GPU is any good for mining before you commit. Hope that helps! Oh, and be worry of scams, there are a lot of crypto scams.
