BLUETTI AC300 FULL REVIEW

BLUETTI AC300 FULL REVIEW – 3000w Modular B300 LiFePO4 Battery Solar Generator – Welcome to another product review. Solar generators have come a long way in the past few years. Bluetti one of the most innovative brands in the market has just shock up the world with yet another incredible offering called the AC300.

BLUETTI AC300 FULL REVIEW

It’s the first Bluetti product to feature fully modular interchangeable batteries support for up to 2,400 watts of solar panels, 3,000 watts of ac wall charging, split-phase 240 volts operation, and the ability to scale up to an incredible 24,000 watt-hours. And it just happens to have programmable, true UPS built-in and app support that will let you control it from anywhere in the world. Has Bluetti just changed the game? Let’s find out.

A. Bluetti AC300 Full Review – Quick Look

Now, if this thing looks pretty big, it kind of is the AC300 that comes with actually no built-in battery. So, this bottom part just has the inverter, the electronics, the charger, and stuff in it, no batteries built. The top part is actually what they call the B300 battery. This is 3072 watt-hours, and you can add up to four of them for every AC300, and you can purchase bundles that include between one and four of these 3,000 watt-hour lithium iron phosphate batteries, and that gets you anywhere from 3,000 to 12,000 watt-hours of power.

1. Bluetti AC300 Weight

Depending on your budget needs, you can also connect a second AC300 in parallel to double those figures and provide 240 volts split-phase support. As for the size and weight, the AC300 itself which is this bottom part is a meager 48 pounds, making it a piece of cake for most people to handle. However, the B300 battery weighs in around 80 pounds each, making them much less tossable, the big built-in handles, however, and small footprint really helps make it more maneuverable as for the display.

2. Bluetti AC300 Display

The display is the same quality color resistive, touch screen as the AC200P and AC200 Max, and it works well with gloves as for the built-in inverter. This supports a massive 3,000 watts pure sine inverter with a 6,000 watts surge that comes with 6 – 20 amp AC outlets and a 30 amp RV outlet as for solar controllers. The AC300 is unique on the market, in that, it has dual MPPT controllers built-in.

3. Bluetti AC300 Controller

It actually has two controllers built inside, and they work independently. You can have different voltages, you can put different things on each. One makes it very versatile, each one of the MPPT controllers in. This can handle up to 1,200 watts of solar, and each one of those lists can do up to 150 volts at 12 amps. So, you’d actually have two arrays of 1,200 watts of solar panels. Both running 150 volts up to 12 amps.

4. Bluetti AC300 Charging Speeds

As for charging speeds, get ready to have your mind blown because the AC300 has a built-in AC wall charger that can charge the unit up to 3,000 watts. That’s right, that’s 25 amps from an AC wall outlet. This is the first solar generator on the market to offer this insane charging rate from the mains, of course, you do need a 30 amp outlet in order to take advantage of this, and the optional 30 amp cable that you can get from Bluetti.

Otherwise, you’re limited to either 15 or 20 amps of charging, depending on your wiring. And these are specifications for the united states at 3,000 watts. You can charge a single B300 battery from zero to 100%, not that cheating zero to 80% stuff. We’re talking from zero all the way to full in under 1 hour, and if you decide to max out the solar on this unit at 2,400 watts,  you can expect to charge the one B300 battery in around 1.5 hours.

The AC300 does in fact support dual charging. So, you can charge from the wall at 3,000 watts at the same time, you charge with 2,400 watts of solar. In that scenario, you can charge one of these B300 batteries in about half an hour. This Bluetti AC300 does support single solar panel charging which was a big issue with the AC200P. It also supports charging from 12 and 24 volts vehicles as well as lead-acid and lithium batteries. Although, it’s going to take you a really long time to charge this thing using 12 volts.

5. Bluetti AC300 Ports

Now, as for 12 volts outputs on this, the AC300 itself doesn’t actually have a 12 volts cigarette lighter output. You can find that up here on the B300 battery. What the AC300 does offer is a 24 volts cigarette lighter socket output and a 12 volts 30 amp accessory output that you can hardwire into a van, or RV, in order to power all your 12 volts stuff. And as for USB output types, the AC300 offers a single 100 watts USB power delivery port two quick-charge ports, and two standard USB ports.

B300 battery offers an additional 100 watts power delivery port, and a quick charge USB port giving you tons and tons of high-powered USB outputs. And as for other outputs, this Bluetti also offers the standard dual 15 watts wireless charging pads on the top which you can’t see because I have the battery on the top right.

Now, do note, unlike a lot of the competitors, you can actually stack the B300 batteries on top of the main unit for making a nice stable tower, and in fact, when you put the battery on top of the AC300, it sort of locks into place. So, they line right up and click in, which makes it a nice even looking stack. The AC300 also offers an app for both apple and android that lets you remotely control the unit via either Bluetooth or wi-fi, it is your choice. Most only offer one way or the other.

Bluetti also doesn’t force you to sign up for a cloud account with them in order to use your app. So, your privacy can be maintained and there are future options to allow EV car charging and wind turbine charging. And of course, like all Bluetti products, it does come with a two-year manufacturer’s warranty, and of course, we took this crazy beastie into our brand new secret laboratory in order to perform all kinds of crazy experiments on it.

B. Bluetti AC300 Testing

1. Bluetti AC300 Capacity Test

Bluetti AC300 Full Review – Final results of the AC capacity test using an electric heater 2,220 watt-hours, the heater ram for 161 minutes. Unfortunately, I didn’t have time to do a 30 hours 12 volts battery capacity test on this model, but I may do that in the future. Now, I did this test four times twice with a 5,000 BTU air conditioner, and twice with a 1,600 watts electric heater. The results were 220 watt-hours out of 3072, or a below-average 72 percent.

I did update the firmware on this to the latest version prior to testing. Hopefully, before Bluetti ships these units to customers,  they can improve these results a little bit. The CEO told me that their engineers were getting over 80 percent in their results. So, maybe they’re using experimental firmware or something else. The new Bluetti AC300 actually supports up to 5,400 watts of charging.

I can briefly show you for a few seconds. This does actually charge at 3,000 watts from a wall outlet. Normally, you have to get the 30 amp plug from Bluetti which is an optional accessory, they didn’t give that to me, so I’m going to plug it in, and show you that it actually will charge at 3,000 watts which is faster than any product on the market from AC wall outlet, and the charger is built-in. Most of the time 1,800 watts – 2,000 watts is the maximum.

a. Part – 1

Okay, the first place we need to go is here. It says max grid input current, and you hit this, and you say yes, and then you have to put in a special password. Now, I know what the special password is, so once you get to this screen, you can choose 10 amps to 30 amps or user-defined which will let you put in whatever you want. By factory, it’s set at 15 amps, I’m going to set it to 30 and we’re going to see what happens here, and watch right here, it’ll say AC input power. I’m only going to let this happen for a few seconds, it’ll be 3,000 watts. Hopefully, we won’t blow the breaker.

There it is 3,000 watts. I’m going to unplug it. So, because I only have a 20 amp receptacle over here, I can’t exceed 20 amps for very long. So, I just wanted to show you guys this can be charged at 3,000 watts 30 amps, but you’re going to need to get their special optional cable, it’s a twist-lock cable.

b. Part – 2

Now, for part two of the max charge rate test. Part one was to show you how much it can charge from the AC wall outlet. Part two to show you how much you can charge from DC sources. The AC300 can take anywhere from 12 to 35 volts when it’s set to other modes. So, you can actually go inside the settings here, it’s the screen that we’re on right now, and you can set, do you want to be in other modes, or do you want to be in PV or solar mode.

Now, here’s something very interesting. First, I’ve ever seen for a product, and the way they have this designed, which is very unique is that they give you this solar cable okay. This is what I call a medusa because it looks like a million snakes coming off of it.  This side goes in the AC300 and then you have two pairs of MC4 connectors. You have two blacks, two reds, so two positives, two negatives.

Now, you’re probably thinking, okay this is just so that you can parallel solar panels right because we’ve seen before where they give you a cable like this and allows you to put multiple panels in parallel. This is not the case, these are actually two completely separate MPPT controllers. Inside the AC300, they have two controllers, not just one. This allows you to run 1,200 watts of solar up to 150 volts on each one of these. So, you can have a whole bunch of panels on one side, a whole bunch of panels on the other side for combined 2,400 watts of solar.

Now, here’s what gets really interesting, they give you all these other adapters where you can put battery clamps on one side. You can put 12 volts cigarette lighter on one side, and you can use both at the same time from completely different voltage sources because there are two different controllers inside. So, you can have one charging from a lead-acid, another one charging from solar. You can kind of do whatever you want, this is really really cool. I like the way they implemented this.

So, I have right here my variable voltage charger, I have a pair of mc4 coming out of this charger. This allows me to change the voltage from practically zero to about 52. So, what we’re going to do, we’re going to pick any pair of these because it doesn’t matter which ones you use, the blacks are ground. So, it goes by the red ones. One of the reds is PV1, the other one’s PV2. They’re not labeled, so you don’t know which one is which you just have to kind of plug it in, and look on the screen.

I’m going to pick any two, it doesn’t matter. Okay, so here DC1 input source PV, DC2 input sources PV. So, we’re going to change both of these to another, and that’ll allow us to do 12 to 35 volts. Now, we’re actually charging using 13.4 volts which is what you’d get from a standard vehicle that’s running or a full lithium-ion battery. Now note, in 12 volts mode, or 24 volts mode, you can only charge it 8.2 amps. So, I do need to make a correction here the limit. On the other mode is up to 24 looks like around 25 volts, and then it goes. I thought it was originally 35 volts, they don’t mention in the electronic manual that I got, what the voltage limit is when you’re in the other mode.

It looks like, it is only 24 – 25 volts because as soon as I exceed that, we stop charging. Let’s go ahead, and go into the settings and switch those to PV mode. Now, I have my big 1800 watt charger. This does 48 volts at 37 amps, now the input is limited on this to 12 amps per circuit. So, I’m not going to be able to max out this charger by any means. I have this tweaked to about 50 volts, it’ll supply virtually unlimited amps to the Bluetti. I just want to see how many watts can we actually get at around 50 volts. So, you can see there are 580 watts at 50 volts. Okay, so that’s not very impressive, what I’m going to have to do is use my voltage booster, and see if I can get the voltage higher which will use more amps out of this.

I have my 1,800 watts charger going into this voltage converter, so here we go, I’m going to go ahead and plug it in. Boom, instantly, 1150 watts. So, there we go, the proof is in the pudding that we know, each leg of the PV input on this can take at least 1,200 watts. It might take a little bit more but as I said, I don’t have the equipment to push this any harder.

Now, it’s time to test the various DC outputs on this, what’s very strange, and something I highly disagree with is, that Bluetti put a 24 volts output on this, that’s a cigarette lighter. So, you know, what this means is the general public doesn’t understand voltages. They’re just going to plug in their 12 volts appliance into that cigarette lighter, and it’s going to blow it up. I’m going to tell Bluetti, if there’s something they can do with the production model to put a warning or something some way, so people accidentally think this is a regular 12 volts cigarette lighter output. Because this will fry a 12 volts device in seconds by the time, you figure it out, it’s already going to be smoking.
