  • Post in thread: Battery capacity tester with data logging

    Thanks for reply. Your reply made me realize that I can separate data logging part and variable load part.
  • Post in thread: Bluetti AC200 & AC50S

    I assume you want to use PV input port (700W max). Charging voltage on that port is 35-150V, so you need to upconvert alternator's output, if it's 12V or 24V. Since AC200 already has built-in MPPT charger, all you need is step up voltage converter. You don't need Renogy DC-DC charger.
  • Post in thread: Bluetti AC200 & AC50S

    There seem to be multiple companies involved to market AC200. I don't surprise if similar products pop up with slightly different specs and different names. As I understand, AC200 is marketed and sold by Maxoak as part of Bluetti brand in the U.S. Bluetti is just name of product line, not a...

    No. Volts x Amps = Watts.
  • Post in thread: Battery capacity tester with data logging

    I'm looking for a battery capacity tester with data logging functionality. I did some research and found these. Does anyone have experience with them or have other suggestions? Atorch is much cheaper than CBA IV. But apparently, the app is really bad and not usable according to feedbacks. West...
  • Post in thread: Bluetti AC200 & AC50S

    You are correct that AC200 has two inputs. One is 2-pin Aviation connector and used for solar (700W max), included car charger, or extra AC adapter with XT90 Connectors and Aviation plug SA201 cale ($110 option), but you can connect any DC power source to it as well, as long as you stay within...
  • Post in thread: Charging and discharging simultaneously

    Hi, super beginner here. I often see diagram like this. My question is, can I charge my battery from solar panel and use inverter to run AC appliances at the same time? TIA
  • Post in thread: Battery capacity tester with data logging

    I know. Values are not separated by commas in the data file.
  • Post in thread: Charging and discharging simultaneously

    How come it doesn't confuse charge controller?

    Here is discounted link to AC200. https://bluetti-ac200-most-versatile.kckb.st/21c596c2

    I wonder how NCA cells achieve 2500+ cycle life? Their cycle life is normally 500.
  • Post in thread: Charging and discharging simultaneously

    Thank you all for replies! I really appreciate it! But I thought charge controller does more than just on/off. The attached image is from Renogy charge controller's manual. It says there are 4 charging stages. Let's say I'm in Boost stage and if I turn on something connected to the AC inverter...
  • Post in thread: Anyone use Leoch batteries?

    Has anyone used LiFePO4 batteries made by a company called Leoch that is running this campaign now? If so, how do you like them? When it comes to LiFePO4 batteries, the names I hear often are Battleborn, Renogy, Dakota. I have never heard of this Leoch, but apparently, they are well-known in...

    Cool, thanks. It looks like better than Victron smart shunt.
  • Post in thread: Battery capacity tester with data logging

    I should have reported this sooner, but I bought an Atorch DL24P. It has been working great.
  • Post in thread: Bluetti AC200 & AC50S

    If you haven't figured out yet, they are the same type but one is male and the other is female.
  • Post in thread: Battery capacity tester with data logging

    Correct, you need an external power. The device has no memory of readings. It's not CSV but a text file.
  • Post in thread: Bluetti AC200 & AC50S

    I have read this thread and am aware of those numbers. Still, 1200 to 1400 sounds much higher than 500. I am aware that shallower DoD will increase cycle life, but didn't know slower charging has such significant effect.
