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].

Review AC300 Portable Power Station

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.
