Review Bluetti AC300 Portable Power Station – The AC300 uses a dual-core controller (ARM controller + DSP controller) which combines digital and analog signals perfectly to manage and control the MPPT module, the AC Inverter module which uses a bidirectional topology supporting AC reverse fast charging, and the DC-to-DC module. The AC300 does not have a built-in battery pack, requires at least one B300 connected, and supports up to four B300 battery packs connected.

- 2400W Unrivaled Solar Input – Time to plug into full-time solar life! BLUETTI AC300 is now capable of receiving 2,400 watts of unrivaled solar charging input. With BLUETTI’s advanced MPPT controller, you can juice up a B300 (3,072Wh) battery module as soon as 1.5hrs Use only the sunshine!
- 3000W Pure Sine Wave Inverter – Packed with a 3000 watts pure sine wave inverter and able to adjust the AC charging rate (no need for a power brick, one charging cable will do just fine). The AC300 power system can also be charged at 1800W to 3000W via wall outlets according to your needs.
- 5400W Blazing Input Rate – Waiting for recharging is never a pleasure. With both the wall outlet and solar panels plugged in, the AC300 can support up to 5400W* horrendous total input rate. Plug the system in before you pack up for the camping, and your power will be ready when you are. *The 5,400W input rate combines 2,400W solar and 3,000W AC, which requires at least two B300’s packs. Or the input rate would be limited to 3,000W with only one B300.

- DC1/DC2 consists of both the positive pole and negative pole of the MC4 plugs. Both DC1 and DC2 input sources can be set on the touchscreen: (Mainpage – Settings – DC1/DC2 Input Source).
B.3. Language Setting & ECO Mode
- Press the “English” or “Japanese” icon to set it as the system language display of your AC300.
- ECO: The power-saving mode of the unit to turn off the AC output to conserve energy if the AC load is less than 30W over 4 hours.
B.4. Working Mode
The AC300+B300 defaults to Standard UPS Mode. There are 4 working modes you can select in settings:
- Standard UPS Mode: Default working mode.
- Time Control UPS Mode: Suitable for areas with peak and off-peak time-of-use rates in order to save money.
- PV Priority UPS Mode: Recommended for areas in stable power supply.
- Customized UPS Mode: Customized the parameters for a better user experience. For more details on each UPS Mode setting, please read Chapter 10. UPS.
B.5. Max. Grid Input Current
- Please check the specification of your grid, sockets, connections, wires, etc. to determine the maximum allowable current that can be drawn by the AC300. BLUETTI is not liable for any damages, injuries, or any other legal responsibility incurred directly or indirectly from changes made to this setting.
- Max. Grid Input Current: limit the Max. the input current of the tied grid, when the current exceeds the preset value, AC300 will take charge to be the power source of the circuit.
Note: Only take effect when AC300 has been connected into the grid. The value presets are at 15A. Email the render for a safety password to unlock the Max. grid input current limit.
4. How To Recharger AC300 And B300
- The AC300 includes two charging ports that can be recharged in different methods. They will be covered in three different sections according to which port(s) are being connected.
- The two ports are named Aviation Charging Port 1 [CP1] and Aviation Charging Port 2 [CP2].
AC300+B300 supports AC, generator, solar, additional adapter, car, lead-acid battery, EV, wind turbine, and DUAL charging through Aviation Port 1 [CP1] and Aviation Port 2 [CP2].
4.1 Charging Method 1: From Wall Outlet (by AC charging cable)
Connect the AC300+B300 from CP1 via the AC charging cable to the wall outlet @1500W/100Vac, @1800W/120Vac Max. The charging process will automatically stop when it reaches 100% capacity. Additionally, you can choose to access the BLUETTI Sub Panel or the L14-30 receptacle, the maximum charging power allowed will be up to 3000W.
DO NOT charge the JP/US version(100-120V) AC300+B300 through 220-240V circuit.
4.2 Charging Method 2: From Generator (gasoline, propane, or diesel)
- Connect the AC300 from CP1 via the generator charging cable (sold separately) to the AC output of the generator. The charging process will automatically stop when it reaches 100%.
- The required output power of your generator has to exceed the Max. input power of the AC input port of the AC300. Also, a generator with a pure sine wave output is recommended (e.g. Inverted-based Generators) Voltage limit: 85-110VAC/JP(100VAC),102-132VAC/US(120VAC), 207-253VAC/EU/UK/AU. Frequency limit: 47Hz-53Hz(50Hz),57Hz-63Hz(60Hz).
4.3 Charging Method 3: Solar Panels (via 4pin aviation-MC4 cable)
- For regular solar panels:
The AC300+B300 supports two PV inputs. Each individual input supports up to 12A and the charging voltage should be between 12-150V. The AC300+B300 can achieve a combined maximum of 2400W of total solar input.
a. User can connect solar panels in series.
b. Connect the MC4 port of solar panels to the MC4-Aviation cable.
c. Plug the Aviation cable to the middle input port on AC300. - If you choose roof/rigid panels to be the solar power source to charge your AC300+B300, the user can easily connect your rigid panels with the MC4-to-Aviation cable to your AC300+B300. The optional PV Module (additional accessory) is required to step down the voltage if the open-circuit voltage produced by your roof panels exceeds the limit of AC300 can handle: 12-150VDC, 12A*2.
Note: This PV module doesn’t work with solar panels that have built-in microinverters, and open-circuit voltage over 550V.
4.4 Charging Method 4: Car Charging
- Press the power button and connect it to the cigarette lighter port through the car charging cable.
- Enter the setting interface as shown through the display screen to set the DC1/2 input source to others; The product can be charged with 8.2A maximum current.
4.5 Charging Method 5: Charging via Lead-acid battery
- Connect to the positive and negative poles of the battery through the provided solar charging cable(pay attention to distinguish the positive and negative poles of the battery, the red clamp indicates the positive pole, and the black one indicates the negative pole).
- Tap “setting” on the homepage to set the DC1/2 input source to “Others” to charge from the lead-acid battery
Review Bluetti AC300 Portable Charging Method 5: Supports charging the AC300+B300 with CP1 and CP2 at the same time. You can use any charging methods listed previously, simultaneous, to maximize charging power input. They are listed here again for your convenience. Select one method for CP1 and one method for CP2 for simultaneous charging.
