• Q10: Can the AC300 be used alone?

  No, the AC300 has no built-in battery. Please use it with the B300 or B300K battery.

• Q11: Where can I buy the solar panel extension cable? Will it affect the solar input power?

  You can purchase solar panel extension cable on BLUETTI Store. Please note that the longer the cable, the greater the power loss in the solar input.

• Q12: How to install the AC300+ B300K system for home backup?

  For details, please refer to "How to build a partial backup system with AC300+B300K".

• Q13: How long will the combo power the devices?

  Runtime = Capacity × DoD × η ÷ (load power + self-consumption) 
  Note:
  1) DoD refers to the Depth of Discharge, η is the local inverter efficiency. DoD=90%, η=90%.
  2) The above data is for reference ONLY.

• Q14: What is the self-consumption of the AC300?

  When the AC300 is on standby, it's 20W with AC and DC off, and 50W with AC and DC on.

• Q15: How long does it take to fully charge the AC300+B300K?

  Charging time (estimated) = (total capacity / charging power) + trickle charge time
  The trickle charge time for BLUETTI power station is typically 0.5-1 hours.

• Q16: What is the Max. charging power of AC300?

  1. 3,000W Max. with 1* B300K (PV+AC);
  2. 5,400W Max. with 2* B300K or more (PV+AC).

• Q17: How many solar panels can I connect with AC300+B300K? How to connect them?

  AC300 support dual MPPT, each MPPT of AC300 accepts 1-6* PV120 / 1-5* PV200 / 1-3* PV350 / 1-3* PV420 solar panels.
  Series connecting is highly commended for the best efficiency and durability.

• Q18: Can the solar input current exceed 15A?

  Yes, but the extra current will be wasted.

• Q19: Can the solar input power exceed 2,400W?

  Yes, however, please ensure the total voltage does not exceed 150V

• Q20:Can l use third party solar panels to charge AC300?

  Yes, as soon as the solar panels meet the following conditions:
  1) Total Voc: 12V-150V
  2) Total power: 2,400W Max.
  3) With MC4 connectors

• Q21: Can I charge the system by connecting the expansion battery to solar panels or an adapter?

  Yes. However, in this case, the AC300 will not display the charging power.

• Q22: How to maintain and store the AC300+B300K?

  1. When the SoC drops to 5%, please charge the product immediately.
  2. Before storing the product, charge it to 60% SOC to keep it in optimal condition. In addition, power off the unit and disconnect all electrical connections from it.
  3. Store the product in a cool and dry place, keeping it away from flammable or combustible materials and gases.
  4. The power station can be safely stored within a temperature range of -20°C to 45°C ( -4°F to 113°F). However, if the storage duration exceeds one month, it's recommended to maintain an ideal storage temperature of around 30°C (86°F).
  5. Fully cycle the product every 3 months to maintain the battery's health.

• Q23: Can I connect different types of solar panels to the AC300?

  Yes. AC300 features dual MPPT charge controllers, please ensure the solar panels in each controller are consistent.

• Q24: What to consider when recharging the AC300+B300K from a generator?

  1. The generator's output voltage, and frequency should fall within the range of AC300.
  2. If your generator's output power can't meet the AC300's input specs, you can easily adjust the Maximum Grid Input Current via the app. This ensures your generator can still efficiently charge the AC300.
  3. Use a generator with sine wave output.

• Q25: Can I charge the combo from solar panels, a car, and AC power simultaneously?

  Yes. The AC300 + B300 combo can draw power from AC, solar panels, and car outlets simultaneously, thanks to its dual DC inputs.

• Q26: Can I charge the AC300 from a 12V/24V DC/DC charger, MPPT controller, or other solar controller?

  Yes. However, the Max. charging power is limited to 100W (12V) or 200W (24V). Please set the "DC input source" to "Others".

• Q27: ls AC300 waterproof?

  No, please use and store it in a cool and dry place.
