I use this product -AC300, B300 mainly to store and save solar PV power with 100W plus panels. This AC300 supports 3000W load across 110V AC power down to 5V USB power and many interim DC voltage levels like 12V and 24V RV power. The AC300 and one B300 can store over 3KW-hrs of power and is extremely scalable, up to 4 B300's per AC300, and if you link 2 AC300s with the fusion box for local 120V/220V outlet(s) or with the sub box (intended for home AC 120V and 240V integration) then you double the AC300 voltage capability to 220v and share ALL the B300 capacity up to about 24KW-hr capacity (two loaded AC300s and eight B300's).Now THATS OFF GRID POWER AND STORAGE. The AC300's are web-cloud accessible too from your smartphone with the free bluetti app to monitor them ... MoreI use this product -AC300, B300 mainly to store and save solar PV power with 100W plus panels.

The AC300's are web-cloud accessible too from your smartphone with the free bluetti app to monitor them 24x7 over a Wi-Fi home 2.4Ghz connect. These AC300's also have, per unit, two channels of MPPT PV regulated input of 1200W each with a 150V max per channel. Use your panels or Bluetti's (their panels are foldable and excellent) and setup 1200W x2 of PV input PER AC300. Ive set this up personally 3x and it is very impressive. So wall-charge over AC from your home solar or when the rates are cheapest then use it later any time, or collect PV POWER to use anytime--I do both daily. There are SO MANY best in class features but I give Bluetti my highest endorsement--great products, innovation, service and technology all in one. Try this solution confidently you need this capability for a known need or just for power security in outages and to insulate against power costs going forward. This is the product to buy. Ive tried it all as a professional Systems Engineer and Solutions Architect, this product is ideal and Ive proven and tested it to be THE BEST...and there are many more features than I commonly use, UPS customizability and flexibility in charge configuration--best around...

I have been buying products from Bluetti for over a year. I am very happy with their sales, products and especially their service. I have communicated with them many times and get a very quick response. I have gotten to know many of the support people by their first names and I feel they know me an my needs personally. I own 1 AC300 solar generator, 5 B300 batteries, 2 B230 batteries, 1 AC200Max, 1 AC200P, 1 EB55 and 1 AC10. We live in the Palm Springs are where the most important part of electrical use is Air Conditioning. No A/C no survival.

We live in the Palm Springs are where the most important part of electrical use is Air Conditioning. No A/C no survival. Our biggest fear here is a GRID DOWN situation due to a major earthquake or terrorist and/or war scenario or weather related. I study GRID SECURITY NOW! website that educates us to the possibility of losing our electricity for a long period time. I have over 23000 watt hours and 20 solar panels to keep my A/C window units and refrigeration and fans and communication alive. Sunday I watched 60 minutes and they did a series on THE GRID. This reinforced my plan to prepare for a scenario that would leave us without electricity for weeks or even months. My Bluetti equipment is here to save our lives if this were to happen. We are also stocked up with 6 months of food and water, TP and survival equipment along with Grid Down Bluetti survival Solar generators and Batteries and solar panels. At this time I use and test my Bluetti equipment every day. I use my AC200 Max and B230 batteries for television and fans. I use my AC300 and 4 B300 batteries for Window Air conditioning units that I use daily mostly after 4 pm and all through the night. Then I start charging them again in the daylight hours. If there is not sun (we get 300 days of sun a year here plus) I have a 7500 watt generator with propane or natural gas that will charge the batteries quickly and efficiently. I have a second 5000 watt generator (propane) as a backup. I also have 10 large propane bottles and a natural gas house hookup. I probably have $20,000 dollars invested in Bluetti products for survival and I look at it like insurance. My fire insurance costs me $1100 per year and my earthquake insurance costs me $1200 per year. Bluetti is my GRID DOWN insurance plus I use it daily to save electricity cost when electricity cost are rising at exorbitant rate with no sign of slowing. I am a prepper and survivalist and I feel Bluetti has the best quality product and my confidence in their backup and support make me and my family very secure. THANK YOU so much Bluetti Company and the entire Staff.

First off, I just want to commend Bluetti for the way they package their products. We know these days, that with the massive increase in home deliveries, that our packages are abused more than ever by the delivery company's. I have purchased the AC200p along with 3 PV200 solar panels direct from Bluetti, and my EB70S from their website. I have now, also ordered the B300 through their website. All arrived in pristine shape due to being packaged very well. Bluetti double boxes their products in heavy duty cardboard, along with some serious closed cell foam to protect your purchase. Every purchase arrived in pristine condition. My order arrived very quickly from a US warehouse. I have also had good results when I have needed support. I have always received prompt ... MoreFirst off, I just want to commend Bluetti for the way they package their products.

Every purchase arrived in pristine condition. My order arrived very quickly from a US warehouse. I have also had good results when I have needed support. I have always received prompt responses to my questions, no matter how trivial they may have been :). This B300 is going into service alongside my current power stations, the AC200p & EB70S. They are primarily charged up with my 3 PV200 portable panels from Bluetti. With this setup we can camp comfortably for a week running my dc fridge and charging anything else we might need. We have also used this setup to run a projector to watch movies during our camping trips with great success. When we are not using them for camping, I use them at home to charge all our devices. I also have a transfer switch installed into our main circuit breaker panel, so that the AC200P and B300 can be used to power important loads during a power outage at home. I'm eventually going to add some rigid panels to my roof so that I can easily keep my Bluetti power stations powered and save the folding solar panels for my camping trips and emergency use only. Looking forward to the time I can extend my capacity with a few more B300's. If you are looking for flexibility in your solar generator system, as well as a company that provides prompt support and stands behind their product if you have problems, look no farther.

I purchased the Bluetti AC200P about a year ago. The intent was to have it provide some backup power during an outage but also to be used nightly to run a window AC unit. I can keep the rest of the house a little warmer and just cool the bedroom. I purchased one of the most efficient window units I could find and the AC200P was able to run it for about 6-7 hours during pretty warm nights. I also had to run the AC using grid power to pre-cool the room. I needed to expand the capacity of the AC200P so that I could run the AC unit longer. I also did not like running the AC200P down to zero every day. The B300 expansion battery provides the capacity I need to run the AC unit all night long.

The B300 will also provides enough additional capacity to run the AC200P during power outages. I used to worry about buying one of these products and then seeing a newer and better product come out. With the B300, I know that I will still be able to use it in the future as I eventually hope to purchase another B300 and the AC300 to complete a system for my future needs at an off-grid cabin. And from what I've read, Bluetti will offer future products that will be backwards compatible for B300 usage.I was concerned about having a big item with sensitive components shipped, but the B300 came packaged really well with a box within a box and thickly padded foam inserts. Even the outside box also had stiff cardboard edge supports to help during transit.Overall, I am very satisfied with the B300 as I've been running test charges on it and using it to supplement my AC200P to power various items.

Expansion battery came two days earlier than their website estimated the delivery date and had a 60% State-of-Charge (SOC). I went through the calibration steps (fully discharge, fully charge), then tested it with my AC300 and AC200P. Both solar generators easily utilized the expansion battery in their respective fashion. Overall, I am very pleased with the flexibility this expansion battery provides to power either of my solar generators in emergency situations. I can even charge and use this expansion battery by itself, to power 12vdc devices, laptops, my CPAP machine, and USB devices - all without the need for a solar generator. Charging this expansion battery was easy via 120vac and solar panels!

This is my second system purchase from BLUETTI. I have bought the first system for my mom around Thanksgiving of 2021, directly from bluettipower.com. The first system had an issue adjusting the incoming charging current (could not change via UI) and the BLUETTI support promptly provided us with a replacement unit that was functioning perfectly, for which I am very thankful.I have initially purchased only the AC300 + 1xB300 for my mom, but given these desperate times of economic uncertainty I have decided to buy more. I have ordered one more B300 for my mom's system and I have also purchased AC300 + 2xB300 for myself. If gas prices will be well over $30 per gallon and rationed and if electricity will be shut off indefinitely, we will be fully independent with our ... MoreThis is my second system purchase from BLUETTI.

We use clothes washer, microwave, TV, mini-oven, bread baker, toaster, fans, flat top cooker, and more with it. Wireless cellphone charger on top of AC300 is a very nice feature as well. It is quite a powerful system. The input power from solar panel is also impressive. We currently have a 1 KW/h of solar panels connected to it, but the AC300 system can also support up to 2400 watt hours input from solar if we decide to expand in the future.I highly recommend this BLUETTI product and would also highly urge everyone to get one while you still can in these desperate times of global uncertainty.

Arrived 10 days after order

I ordered on the 15th and arrived on the 25th. Communication at the beginning was slow but it was a long weekend. Once the order was fulfilled a tracking number from FedEx was received and two large boxes arrived well packaged.Pro's everything seems to work as advertised.Con's took a while to figure out you need to lock the connecting cable to get the top unit to power on. I used 3 350 watt Bluetti solar panel cells to charge the battery from 65% to 100% and it took just over 1 hour. The three gave me 750 watts which I will need to play with to see if I can get closer to max.The units are very heavy and together over 100 lbs. I went and purchased a hand truck so it will be easier to move around. The length of the solar panel cords and supplied DC connector was ... MoreI ordered on the 15th and arrived on the 25th.

I went and purchased a hand truck so it will be easier to move around. The length of the solar panel cords and supplied DC connector was short for me. I also went in and purchased from a third party a 30 foot extension so that I do not need to haul this outside if I want to charge via solar. You can connect everything but will need to move the heavy battery outside with out an extension addon. These extra accessories are not available on this website. If they had been probably would have bought them here.Was sent a fancy glass thank you. Would have rather a card and the money used to make and ship this heavy thank you put to the donation to African families.

Backup Power Solution

I received the extremely well-packaged BLUETTI AC200MAX sooner than expected. It was exactly as pictured and described by the Seller. Installing the BLUETTI app on my cellphone and connecting it to the power station via Bluetooth was very easy to do. Using an Anderson PP to XT90 adapter, I had no problem connecting the solar input to a watt meter (to know volts) and a 120W solar panel. The AC200MAX was able to instantly see a mere 10V of charge when the solar panel was placed on a window sill, indoors, on a partially cloudy day. I know others disagree, but I really like that the AC200MAX uses an external power brick. I much prefer that the added weight and heat NOT be inside the unit itself. I recently purchased the BLUETTI D050S Charging Enhancer so that, alongside ... MoreI received the extremely well-packaged BLUETTI AC200MAX sooner than expected.

Thank you BLUETTI for developing such a wonderfully well-engineered backup power solution.

Good, but needs some work

We bought this system to serve as a primary source of power for my RV while traveling and boondocking.We plan(ned) on buying two to have 240v service as our RV is 240v and 50 amps. Having two 3000 watt inverters would cover most scenarios with 3000 watts available on both legs, and we understand we will not have true 50 amps available given our intended installation.So far the experience has been mediocre which has me contemplating the second purchase. When it works, it works great.The system has zero tolerance on even a millisecond of overload. This is acceptable to the point where I can just install some soft starts where necessary.The app is extremely finicky, and mostly useless unless you just want to stare at input/output and be able to tweak minor ... MoreWe bought this system to serve as a primary source of power for my RV while traveling and boondocking.We plan(ned) on buying two to have 240v service as our RV is 240v and 50 amps.

This is acceptable to the point where I can just install some soft starts where necessary.The app is extremely finicky, and mostly useless unless you just want to stare at input/output and be able to tweak minor settings.It would be extremely helpful to be able to see more detail on faults and reset them from the phone, especially when a fault happens while we're driving.As an example, I'm on the road as I'm writing this and can't get the AC back on without us pulling off to a rest area to reset the entire thing, so on goes my generator. Hitting the AC toggle over and over again does nothing and just says "Loading". The DC toggle works just fine. This happens on several tablets and phones.I'm not sure why there is even a power button. The only way to reset the unit is to unplug shore power and the battery pack. At least hitting the power button tells you to kill all incoming power.I believe most of this can be fixed with firmware updates, and hope the company takes the time to iron some of this out.As stated above, when the unit is stable, it works well and handles all of the loads I expected it to. The 3072AH battery drains faster than my calculations, but I believe that to be the buffer on the full state and discharge state to prolong battery life.Overall happy, but not sure this system will serve the purpose I hoped it would at the price point.

High No-Load Power Drain

While in many respects the Bluetti Power Stations are well designed, there is a serious flaw that I have measured in my two Bluetti AC300/B300 units and my AC200 model. My plan was to use the AC300/B300 units for backup power, a common usage. The problem is that these units, like my AC200, show a very high no-load power drain. When the AC300/B300 units are turned on and the AC mode switch is also turned on (as would be common for the use as backup power) there is a power drain of 60 watts with nothing plugged in or with devices plugged in but not turned on (based multiple tests). Over the course of a day about 60x24 or 1440 watt-hours will be used even if nothing is actually powered. This is almost half of the B300 battery capacity, a serious waste of capacity Based ... MoreWhile in many respects the Bluetti Power Stations are well designed, there is a serious flaw that I have measured in my two Bluetti AC300/B300 units and my AC200 model.

Over the course of a day about 60x24 or 1440 watt-hours will be used even if nothing is actually powered. This is almost half of the B300 battery capacity, a serious waste of capacity Based on similar tests my AC200 draws 35-40 watts of power with AC on and no load. (Also the battery current is 0.7 amps and the voltage is about 51 volts with AC on and no load). Others have reported very similar results for the AC200 and AC200P on the internet. I have reported these concerns to Bluetti with no response so far. The no-load power draw for these units is about four times as large as for my other power stations. There is also a smaller power draw observed by just turning the units on with no AC or DC on (0.1 amps for my AC200) or with DC only on (0.2 amps for my AC200), but the worst and unacceptable drain is the background no-load power usage with AC on.
