BLUETTI AC200MAX Portable Power Station User Manual
BLUETTI AC200MAX Portable Power Station User Manual
Please read this manual before use and follow its guidance. Keep this manual for future reference.
BRIEF INTRODUCTION
For I/O capability, the AC200MAX features higher continuous output power at
2,200W from its pure sine wave inverter, a 100W PD3.0 USB-C port, an upgraded
MPPT controller which now handles up to 900W of solar input, and a built-in
30A NEMA TT-30 outlet designed especially for the RV crowds. And most
importantly of all after feedback and listening to our customers, finally, the
BLUETTI AC200MAX supports Bluetooth connection and can be controlled by the
new BLUETTI Smartphone App (iOS & Android). And it too also supports
expandable battery packs.
The AC200MAX supports up to two additional battery packs, using either the
BLUETTI B230 or B300. With two BLUETTI B300 you can easily expand your
AC200MAX to a massive 8192Wh of capacity to run all of your essential needs at
home or on the go for hours, days, or even more than a week!
ABBREVIATION
● BMS: Battery Management System
● MPPT: Maximum PowerPoint Tracking
● SOC: State of Charge
● AC: Alternating Current
● DC: Direct Current
● PV: Solar Panel(s) Charging (Photovoltaic)
● Grid: Home Power Supplied by Utility
● T500: 500W Adapter
● DOD: Depth of Discharge
● ECO: A power-saving setting for the AC200MAX. While it`s on, the AC output

SAFETY INSTRUCTION
● DO NOT place the power station near heat sources. It is prohibited to place
the equipment in an environment with flammable, explosive gas, or smoke. It is
also prohibited to operate the equipment in this environment.
● DO NOT attempt to replace the internal battery or any other component of the
equipment by anyone other than authorized personnel.
● DO NOT operate in wet conditions. If the equipment becomes wet, please let
the unit dry completely before using.
● Please ensure proper ventilation while in use and do not obstruct fan
openings. Inadequate ventilation may cause permanent damage to the equipment.
● DO NOT move the unit while operating as vibrations and sudden impacts may
lead to poor connections to the hardware inside.
●Warning: DO NOT insert foreign objects into any ports of the AC200MAX
(both AC & DC & ventilation holes). The power station generates the same
potentially lethal AC power as a household wall outlet. Please use it
carefully and keep children away from it.
● In the case of fire, only a dry powder fire extinguisher is suitable for the
product.
● For safety purposes, please use only the original charger and cables
designed for the equipment. We are not liable for damage caused by third-party
equipment and may render your warranty invalid.
BLUETT APP
Search for “BLUETTI” in the App Store (for iOS devices) or Google Play (for
Android devices) to download the BLUETTI App to remotely control your
AC200MAX.
The AC200MAX can be controlled via Bluetooth. In order to access the AC200MAX,
please launch the BLUETTI App once downloaded and installed, and tap the
“Bluetooth CONNECT” icon to register your BLUETTI AC200MAX.
The basic information of your AC200MAX can be viewed after the unit has connected with the App successfully. Press the ‘’gear icon’’ to customize the current working mode and parameters of your AC200MAX under “Settings”.
NOTE: Please keep your phone within 5m/16.4ft of the AC200MAX in order to reduce connectivity issues during update.

press the power button, then enter the main interface through the touch
screen, tap the DC ON/OFF button and confirm.
(2) Turn off DC Output, tap the DC ON/OFF button and confirm.
(3) Turn on AC Output: press the power button, then enter the homepage through
the touchscreen, tap the AC ON/OFF button and confirm.
(4) Turn off AC Output: tap the AC ON/OFF button and confirm.
APPLICATION SCENARIO
(1) Outdoor
Car equipment: car fridge, car vacuum cleaner and other car equipment;
Camping equipment: garden electric tools (power tools such as blowers, lawn
mowers, electric drills, electric saws), BBQ grills, LED lights, etc.
(2) Indoor Refrigerator, kitchen devices such as kettle, toaster, blender,
coffee maker, rice cooker, laptops, phones, lighting, etc.
EXAMPLES OF LOADS
(1) 12V/30A, 12V/10A, cigarette lighter port, USB-A and USB-C output port are
suitable for most products in the market, but some products may trigger
overcurrent protection if there is a large current impact at the moment of
starting.
(2) The power of electrical products used for AC output should be less than
2200W. According to the different electrical products, when the rated power is
less than 2200W, some air conditioners, motors and other devices that need
instantaneous high current when starting may trigger overcurrent when the
ratio of peak value of rated current exceeds 3:1. At this time, we recommend
that you select the electrical appliances with a lower power rate. (3) When
the output is overloaded, over-current or short circuit, the product will turn
off the corresponding output port, and then it will automatically start twice
(at an interval of 20s). If there is still an overload, over-current or short
circuit alarm, the output port will be locked, and need to be manually
troubleshot and th n restarted. If the output stops repeatedly after the
restart, please stop using it immediately (only after troubleshooting) or
contact the vendor or
maintenance agent for help.
(4) When the battery power is discharged to 0%, the DC and AC output will
automatically turn off. Only when the battery power is charged to more than
5%, the DC and AC output can be turned on, which is to protect the battery and
enhance its cycle life.
(5) This machine supports charging and discharging simultaneously.

FAQS
Is the reverse polarity issue corrected on Amazon based products sold?
Yes it has.
all reviews seems about bluetti ac200p, what is the difference between bluetti ac200p and bluetti ac200max besides little more wattage and price?
There are usually reviews for the product you click on. Try filtering the
reviews.
The 200p has more household plugs and they say the tiny little wattage
difference as you mentioned. The max looks more geared toward campers or
someone that uses a 30amp devices. The only other difference is the usb-c
outlets were upgraded so they work faster now. Other than that, you can see
they’re usually both the same price.
How many solar strips will make 900W? 1400W?
You’re not going to “fry” your Bluetti even if you have more panels than 900W worth. The Bluetti will only input a maximum of 900W, regardless of how many panels you have attached.
Wind turbine charge controller included?
No. Not included. Separate system needed to attach Wind
How long to charge with 200 watt solar panel?
From 0 10 hours
Are these weatherproof for a mild rain? Dust proof?
Yes (dust) and yes (light rain). But it’s not meant to be weatherproof (neither are the Bluetti solar panels).
Can you use universal panels with the AC200 max?
As long as you don’t go above/below the max/min voltage and wattage input, you can use any panels. May need a converter for wiring.
full size refrigerator run time?
The majority of modern refrigerators draw an average of 55 Watts/hr.
Can blue power an electric car?
Not really. You could do a Level 1 slow charge, but it would only give you about 4 or 5 miles of extra range. Keep in mind that EV’s typically have battery capacities of 50 – 100 kWh (kilowatt hours). The Bluetti AC200MAX “only” has a battery capacity of ~ 2 kWh.
How do you use the 30 amp power supply on the rv Indoors when the 30 amp outlet on the trailer is outdoors?
Place the Bluetti under the camper. Remember it is not water proof and does not even like high humidity. Or run the RV cable through a window.
what is battery voltage?
51.2 vdc
How do you Expand to 8192Wh & what is the cost of that?
By using an AC200 max and 2 AC300 batteries.
is there a minimum power output?
Not
What is the storage temperature range for the ac200max?
This should be indicated in the instructions manual.
