💰 Bluetti AC200L Will Pay Itself Off 💵 Grid Tie 

You're very welcome

Lol, I'm Canadian but close enough. My girlfriend is on me about how I've been saying it wrong too. Ugh,

You're very welcome 😁

Welcome 🙏🇨🇦🙏

So far the AC200L has it.

Add some solar and save even more! 👍👍👍

It is pretty amazing. Do you know of any other power station brand this size that can do this?

@@Roll2Videos so I can't honestly say I've heard of any having those features in a system of this size but with there being soooooo many out there now I can't keep up with what has what.I know some of the bigger newest systems do like hysolis Apollo but I'd think if they did they would really advertise it cause it's impressive.

@@scarygary3569 Very true. I've only seen it in larger systems. This is nice it's more adorable.

That is a very good question that I will be testing soon. Please sub to stay in the loop 😁👍

@@Roll2Videoshave been a subscriber since your first Growatt video figuring out the G/N bond stuff.

@@cgutowski471 Awesome, Thank you very much 😁 The more subs I get the more it makes doing this worth it.

I'm still able to fast charge.

@Roll2Videos how many watts are you able to AC charge at? I could AC charge at 2300 Watts before. With no help from solar. That's a pretty cool feature to.

@@diySolarPowerFunWithRay I haven't tried the full 20A. I'm on a 15A breaker. 14A got me to 1500W. Under the charging mode do you have turbo turned on?

@Roll2Videos I have turbo turned on and I also adjusted my amps to 19 and it worked great. I have a 20 amp breaker and 20 amp Outlets. I got the code from bluetti. I'll email it to you :). The 14 gauge charging cord handled it fine but i wouldn't want to go any higher on the amps.

Thanks, I'd like to get the TT30 charging cable if I go any higher than 15A. Just to be safe.

Yes! This has WiFi and Bluetooth. It's really cool to be able to remotely view everything from anywhere.

In this video, I don't have solar hooked up. I do now. This new function will help just that much more. Adding to its awesomeness

That would be great if they can.

Great point, I've put a CT sensor on the AC input. It also takes into account peak and off-peak. I'll do one week measuring no bluetti and one with and see the differences. It will take a long time for payback but so far it's looking net positive.

@@Roll2Videos For sure it'll be a net positive, but at most you'll be able to shift maybe 1.3kwh off peak after losses. That 2400w inverter & any active circuits are probably drawing at least 20w @ idle, so about 480wh wasted a day. Then factor in conversion losses when charging/discharging the batt & that's another 250wh wasted. The savings from shifting 1.3kwh to off peak is maybe 25cents a day and you're stressing all capacitors in the inverter by running 24/7, electronics will go bad before the cells. There is no ROI doing this.

@@CanuckTech Another good point. But also it's a standby power supply. LiFePO4 doesn't like to sit at 100% like all other UPS power stations do. This will let the batteries flex. Granted I agree ROI may not be worth it but at least someone is not buying it and it gets used a few times a year.

That sounds comfortable. When I move out to a more rural area hopefully soon I will be going down the same road buddy. I'm excited 😁

That's a fast turnaround. Nice job 👍 Any solar connected to it?

Granted it would take a long time for the payback, Still a great idea.

@@Roll2Videos compared to some whole home solar system i think its about 20 years to pay for itself. Yikes no thanks ill stick with my minimal/micro solar system. Now if i can only stop my compulsion to but Solar stuff. Its like getting a Tattoo, you get one you have to have more.

@@mannyfragoza9652 If solar was applied payback would be faster. Another good thing is it's a UPS so if the power goes out the loads will still be powered. 👍

@@Roll2Videos 👍👍

Ok, I hear your analogy and it is a good one. How about the characteristics of LifePO4 and the UPS function? LiFePO4 chemistry does not like to be held at 100% high voltage. With these settings, you can set the upper and lower SOC. Would you agree this will increase the overall life span of said battery?

@@Roll2Videos Not sure what you mean by "100% high voltage". But generally speaking, LiFepO4 works very well in UPS style applications. Lets take a 4s (12V) architecture as an example (though generally speaking any new system should be using 48V, not 12V). The basic charging algorithm is to charge the battery to 3.55V/cell (14.2V), hold it there for 1-2 hours to give the BMS time to balance the cells, and then let it drop to its float voltage of 3.35V/cell to 3.375V/cell (13.4V to 13.5V). At the float voltage the battery will more or less maintain its 100% SOC until drawn down lower than that. Notice that the float voltage for a LFP battery is significantly below the bulk target voltage during charging. This alone massively reduces any stress on the battery, even though it is still at 100% SOC. -- Ok, now to answer the question. In a UPS style application, the battery will wind up being held at the float voltage more or less indefinitely. Does this hurt the battery? Answer: A little, but not much and you probably won't notice the difference in life-span. The cells will still outlast the other electronics in the UPS, probably by a lot. A standard charge controller can maintain a battery for UPS applications just fine. It is recommended that you set the float to the lower-end of the float range... 3.35V/cell (13.4V for example) as the float. While not required, it is also a good idea to charge to full once every few months to give the BMS time to catch up on balancing-out any imbalances that develop. You generally do not want to float at a lower voltage than 3.35V/cell because floating at a lower voltage can potentially cause the pack to discharge all the way down to 30% without you even noticing, which defeats the point of using it as a UPS. -- What is the absolute best algorithm for a UPS? It would be to charge to 100%, hold for 1-2 hours, drop it to around 95% SOC with a load, and then disconnect the battery. Rinse and repeat every 3 months or so. Vampire off the mains to keep the inverter on standby and to keep a capacitor charged to drive the transfer relay. Nobody does this, though. There is usually no point. You might save a hundred or two hundred cycles equivalent worth of wear by doing that, out of 3000+ cycles. So it isn't usually worth doing. -Matt

@@junkerzn7312 LiFePO4 is not like lead acid. It's not good for them to be held at the top-end voltage. These power stations use 51.2V nominal voltage which means a fully charged power station is 58.2V. If you hold the battery at 58.2V (100%) all the time it will degrade the battery. Every spec sheet I've looked at says store at 40%-60% if you are storing the station at 100% (the basic function of a UPS) it is bad. If I was running a basic UPS that holds the battery at 100% I would use lead acid batteries.

@@Roll2Videos (1) You didn't read what I wrote carefully enough. (2) A fully charged power station is NOT a voltage, its a state of charge and it is held even when the voltage drops, up to a certain point. Fully charging a 16s (51.2V nominal) LiFePO4 power station to 100% only requires charging it to roughly 3.45V/cell, which would be 55.2V. At least if it isn't too cold. Most charge controllers (properly) charge it to 3.55V/cell (56.8V), and then drop to a float voltage of 3.35V-3.375V/cell (53.6V to 54.0V). A 16s LiFePO4 battery will remain fully charged when held at a float of 53.6V. A UPS using a 16s LiFePO4 pack will generally use that for the float voltage. I don't know what you've read, but anyone with experience with LiFePO4 (which I have), will tell you the same thing. You can use LiFePO4 for UPS applications just fine. They work far better than lead-acid.

@@junkerzn7312 I disagree with your presumption of float
