I use battery-based “solar” generators around the house whenever I need power in places that are inconvenient to run an extension cord. For example, last week my wife and I cooked some food in a crock pot for a relative. We needed to deliver it in the middle of the 8 hour cooking cycle so I plugged the pot into a Maxoak 500 watt battery generator and put the whole thing in the car for the 30 minute drive. When we arrived, we just plugged the pot into their kitchen outlet so it could finish cooking.I figured out a long time ago that the units made by Maxoak were a cut above the others I had bought earlier, so I have stuck with their products since then. I have an older 4,000 watt-hour unit, a 400 watt-hour unit, a 500 watt-hour unit, a 1,000 watt-hour unit and now I just bought their new Bluetti AC200P unit, which is 2,000 watt-hours. I charge all of my battery systems with solar power so I normally don’t use the chargers they include with them. For the AC200P I have ordered some parts to allow me to connect it to one of my solar panel arrays that fall within the 35-150 volts specified in the manual, but for this review, I am using the charger included with the unit.The AC200P is the first product from Maxoak/Bluetti that uses Lithium Iron Phosphate (LiFePo4) batteries. All earlier models were built around Lithium Ion batteries. LiFePo4 batteries are safer and they last longer. That is, if you treat them right, they will continue to provide at least 80% of their rated capacity for 1,000-2,000 full charging cycles. The AC200P will likely exceed even that because the unit is designed to cut off the outputs and charging cycle so that you can only use 90% of the battery’s actual capacity. This is a good tradeoff between usable capacity and life extension. And, the AC200P battery is 48 volts rather than the 12 volts of most solar generators. That should translate into a more reliable, longer lasting AC inverter since it doesn’t need to boost the voltage as far and thus keeping the current lower.The display/touch panel provides access to screens that provide information about the operations of the chargers, the AC load and DC load. There are also six pages of fault indicators so you can better understand any issues that might occur. So far I have only triggered the Inverter Overload fault by running an AC load of 2,200 watts, which is 200 watts above its rating. What was amazing to me is that it continued to operate for about three minutes in that overload situation before shutting off the AC output. I did not try higher watt overloads but I did try shorter duration overloads of 2,200 watts and, even though it beeped whenever I exceeded the 2,000 watt limit, it continued to operate as long as I brought the load below 2,000 watts before 3 minutes had transpired.I did a full load test, keeping the AC load as close to 2,000 watts as I could and it lasted one hour, which is exactly what the 2,000 watt-hour specification says it should. After it reached zero percent charge, the AC output shut down automatically. I had hoped that the AC output would turn back on automatically once the battery had charged back up to 5 or 10% but it does not. You must manually turn the AC output back on after the low battery fault by touching the AC Output button on the touch screen and selecting “ON”. This means the AC200P is unsuitable for long-term unattended applications (like long-term sump pump backup, or for supplying power for a refrigerator inside an infrequently visited cabin that has solar panels for recharging), but Bluetti advertises their generators for portable power uses, not unattended applications.2,000 watt hours is a lot of power. I ran a space heater, a 300w incandescent flood light, a tool battery charger, a large air circulation fan (on high), a large drill and a small heat gun (on low heat) to get to the 2,000 watt limit, and it all ran for an hour.There are six 120 volt outlets on the front and eight 12 volt DC outputs of various types—including one USB-C charging output. There are even two 15 watt wireless charging pads on the top surface for mobile phones with that capability. My phone charges for a while on these pads but I use a thick protective cover which is known to interfere with wireless chargers (and it’s very hard to get it off and back on). My wife’s Google Pixel 3 charges fine without a protective cover.So far the only minor disappointment is the AC self-consumption power. If you leave the AC output on without any AC loads connected (or all loads powered off), the AC200P inverter will consume about 50 watts all by itself. In fact, that 50 watts even generates enough heat that the unit’s fan needs to turn on low occasionally. The AC200P includes an “ECO” mode, which will turn the AC output off if no load is applied for four hours. That will solve the problem for most people, but it seems like they could have put the AC inverted into a suspended state until a load is sensed. That would conserve power and allow the device to remain on and ready for much longer. As it is, leaving the AC200P on and ready to supply AC power with the ECO mode off will result in more than 50% of the battery being consumed within 24 hours. In ECO mode, once the AC output is turned off after 4 hours, the self-consumption is closer to 5 watts. But be aware that you still have to manually turn the AC output back on when you want it to power something after ECO mode shuts it off.The thing I like most about the AC200P is that it allows the highest solar power recharging input of any portable generator I’m aware of (700 watts). That should allow me to recharge the unit from zero to full on a sunny day in about 3 hours, as long as I can configure my panels to reach the 700 watt limit. According to the manual, it will charge the battery whenever the solar panel input provides sufficient power, even if the unit is turned off. That will allow me to leave the AC output off and keep it fully charged and ready for use at any moment. AND, you can charge with both the 700 watt solar input AND the 400 watt wall charger at the same time for an even faster recharge. This is unheard of for a solar generator of this type.Bluetti has clearly placed their design attention in the right places. Touch panel with access to lots of data, lots of power outputs, multiple and fast charging options, even wireless phone charging. It’s a solid generator that is well worth the price.

I bought the AC200P with the intentions of having basic electricity backup in my home for 10-20 days (read further). If I didn't move frequently I would just buy a permanent solar system with battery backup, but that is not financially sound given this. Insert the AC200P coupled with a gas generator (I know, most people only talk about solar to recharge). I have determined that the AC200P meets my electricity needs for a 24hr period of electronic devices/ appliances that it CAN be connected. Obviously it is not going to run my furnace (unless there was some sort of power adapter already in place like some others have installed and displayed on YouTube) or my dryer, etc. I plan on running the refrigerator, lamps, wifi, TV with antenna (100 watts combined 52" TV & antenna), 1,000 watt output microwave (WHICH IS 1,800 WATT INPUT), fans in the summer, 1,000 watt hot plate, separate battery packs and battery powered lights. I DO NOT plan on using this to power an electric heat source. Electric heat sources in my opinion are inefficient heat sources when rationing energy sources. I bought a Mr. Heater Big Buddy Heater for that purpose with the 12' cable to connect to a 20lb propane bottle which can provide me heat in the winter for 10-20 days. I like the concept of solar, however i bought a WEN 2,350 watt gas generator (56235i) to recharge the Bluetti. Why? Because i'm personally just prepping for 10-20 day power outage, not the end of the world and enough solar panels to ensure a full recharge every 24hrs isn't cheap. The WEN generator (~ $450) can run for 7 hours at half load (950 watts running) on 1 gal (full tank) of fuel. I can recharge the AC200P in about 2.5 hours since i bought the second AC adapter to quick charge via AC outlet at 800 watts. If you keep only a small 5-gal can of gas, i have 35 hours of supply at this rate which also translates into 14 days of supply.Update: 09 March, 2021After further research, it is worth noting that if you purchase this product you may want to look at the solar federal tax credit and even a state tax credit. I believe it was updated for 2021 to maintain at 26% not decrease to 22%. I BELIEVE that if you purchase solar panels for this you can technically have an off-grid solar system that meets the threshold for the tax credit. By the time you factor some decent panels in you could essentially get them free given the tax credit. AC200 roughly $1,900 with tax, 4x 200 watt panels and extension cables with tax $840 for a total of $712 in federal tax credit alone. Again, I’m not completely sure there won’t be issues claiming the tax credit but something to look at if you haven’t when making this purchase.Update: 22 March, 2021. I bought 4x Newpowa 200W Monocrystalline 200 Watt 12V solar panels (on Amazon) to connect to my Bluetti AC200P. I tested them last week in cloudy conditions and i'm pretty sure they were not angled very well to maximize their efficiency. During that quick connect test i only got 50-110 watts. That left me concerned.On 22MAR21, it was sunny so I connected them again to see what they could produce. Attached are the images. My AC200P has an input of only 700 watts, so i was over paneling with 800 watts. I still brought in over 700 watts. Objective met. Then I disconnected one panel and tested it again. The three panels yielded over 500 watts continuously. It mostly stayed around 520-538 watts. I'm not an expert at efficiency of solar panels, i'm really just a newbie with some basic research. I thought these panels were good stats for their price. I'm happy with them. After purchasing, I maybe should have looked at getting 24v panels instead of 12v given the specifications of my AC200P voltage range. With these panels i must employ 3 panels to get enough volts to charge my unit. At the end of the day, i'm still happy with the purchase and think it's a good one.Things to consider: These solar panels are not the most mobile, but they are far cheaper than the "portable" ones and can produce more wattage. I only plan on using them at the house so moving from one place at the house to another isn't an issue.

The original first unit arrived 2 days after I ordered it. That was amazing given this is a 60lb beast. Unfortunately, the unit that I received had a BMS fault that prevented it from working. After contacting the seller, Maxtar New Ener. replied promptly and sent me a second unit within two days which I am happy to report functioned really well. I am a happy customer. Kudos to the seller for impeccable customer service. I have recharged it, tested it with a hair dryer pulling 1300 W and ran my CPAP device for one night draining only about 17% of the battery reserve (your mileage may vary depending on number of hours used and whether heating is on or off). I will need to do more tests over the next while such as running my portable12V camping fridge. I wasn't able to test some of the DC ports but the USB A ports, 12V car charging port, wireless charging, and all AC ports functioned correctly. This is only an initial test and impression. I hope the unit will continue to function well in the years to come.Update 25 Oct 2021I have gotten back from a two+ week car camping road trip. The AC200P performed reliably with no issues. It powered the 12V fridge during the day and evenings when it is not being charged through the car's 12V outlet. Even with camping sites with electrical hookups, I still left the 12V fridge hooked up to the AC200P and connected the electrical to the power brick to top up the power station and another extension cord to the tent to power electrical devices and my CPAP. This kept the power station fully charged and provided safe clean power to my electronic devices. There was one site for two days with no electrical and I tried charging with solar with three 200W panels. Unfortunately, the site was quite shaded with tall trees everywhere and it was cloudy. So, I got just enough charge to replenish the power lost through charging the fridge. With my heavy electrical usage, running the 12V fridge two days, my CPAP device 8 hours per night for two nights, I ran the battery down to about 15%. So, in summary, I got about two days of power. Fortunately, my stay at this site was only for two days. When camping, don't choose a site that is too shaded. The unit has performed reliably and running out of power is only due to my heavy usage and blaming myself for choosing an overly shaded campsite. There were ways I could have optimized the power consumption but this was my first time using it. Still a happy camper.

I probably own too many solar generators. BLUETTI is a cut above the rest. Having purchased the EP1500 in early 2021 when they became available in Canada, I was pleased that BLUETTI finally was making the AC200P available in Canada. Yes, still quite a bit more expensive then prices in the U.S., but what isn't these days?For Canadians sitting on the fence or concerned with long product or customer support delays, the Canadian distributor has been stellar. Really quick responses and excellent communication. I ordered the AC200P on Sunday and received via UPS to rural Ontario on Tuesday! Incredible shipping time especially when you hear about the product shipping delays in the U.S. and often sold out.For the unit itself, I'm just going through the testing of the unit now, but so far so good. Build quality is excellent. Quite surprised that it is not as heavy as I expected. That said, one of those small $10 moving carts are an excellent investment to move it around. Has an excellent touch screen to monitor ingoing and outgoing watts... just wish I could crank up the brightness to the max when the sun is directly shining on it.I intend to use it primarily for boondocking with a 20' travel trailer for replacing shore power, while charging it up with solar panels or in cloudy/rainy conditions, via a propane generator using the massive power brick. The size and simple box shape make it well suited for storage and day to day use.Solid product and best in class.

Purchased the bluetti ac200p may of 2021.Used it only 2 weekends in 2021.I have 600 watts of panels on my solar array.This year I've used it for 5+ weeks 24/7 straight. I do plan on using it for 2 more weeks but I have issues now and it's now usable at this point.1-The major issue is the ac wall charger shorted out in the inverter causing the bluetti only to charge on solar.2-Which comes to my second issue is 6 times so far I would have 30+% on the bluetti and it would shut off and say it's 0%. It did this when the ac charger stopped working and now I can't use the bluetti because it has to start with ac power when it's 0%.3- 10+ times during the 5 weeks the inverter (ac) and dc would randomly switch off while the unit was 80%+. (Which would spoil the food in the fridge after 6 ish hours more than once)-inverter is inefficient. I'm losing 2-3.5% per hour on the unit with nothing connected. So if you have the unit 100%, in less than 30 hours it is 0%.Update:Customer service was pretty slow. But I owned the bluetti for 16 months and they just got me to return the unit on there dime and got a full refund. So in the end they backed there product and I can order a newer product from them

FYI, I have been running this unit everyday for almost 2 years.Pros: This is in a work mobile vehicle field situation where it may get drained to 0%, and then recharged over night every night. It has sat in my car as a secondary power source all that time and have been through hot summers and cold winters. So I have beaten this thing pretty good. It is still running like a champ. No issues with supplying the power I need which is roughly 300-500w for several hours work.What I really like is, if I need to take it out and use it somewhere else, it's possible and fairly easy. A traditional fixed secondary battery in car this not possible. This is a huge advantage to me.Cons: the dc charging from 12v car voltage doesn't seem to work??, I've changed the setting to PV input car and still no good. I have checked dc voltage from car and it is steady 12v so something in the 200p isn't right.2nd. The screen doesn't seem to update refresh always. I run it all day, maybe down to 20%, then I'll plug it in overnight so I know there is 100% by next morning. However, the screen may say still 20-30%. What you need to do is power it all off, and then reboot then the screen seems to update. Weird?[2023]: update: still runs strong, I have bought the dc to dc charger for car charging and it works well, maybe 90W input steady from car.[2023]: update: for this price I'm pretty impressed.Conclusion so far: for this price it is the best option IMO for a secondary aux battery source in an overnight car camper or field work solution, it's a champ. It's very solid and reliable over 2 years of daily use.

was ok when working but was not looking enought or use it alot's but now after 1 year power drop 60% to nothing and stop and charge too 99% and don't stop,another problem you can get is unit charge and go from 80% goes up in sec to 100% i have see this too on another and stop charge look for those problems in your first month and hope the machine don't do this after 1 month,because after that good chance you will not get your money back,Buyer beware after the initial 1 month on amazon warranty on this ,kinda hard to be apply in Canada Customer service told me because my purchase is over 1 year and because they are out of stock they could not replace my machine??? and it's 24months warranty,customer service help almost no there except too ask questions and video or picture,will update with video soon,don't buy for 2000$ and a fuzzy 2years warranty almost not real,,chance are you will get a defect unit,they use bad cells im stuck with a over 2200$ machine defect and when i try to talk customer new guy who don't seem too know much about ac200p and is kinda rude,i suggest you if you try maxoak be sure to do alo'ts of test on your machine because they cells are not good when the first of those was create ,all cells power was visible on menu now they have hide this,because it would be more easy for customer to see the bad cell on the menu!!!,i will put the video on my Youtube channel with the name ac200p bluetti maxaok from amazon ca defect look for it the small video version will be here too,don't buy and the other more recent model seem to have problems too look for 1 star review
