Only used it once so far, it powered everything including an air conditioner, hot water system, fridge & TV in our camper for the use of 40% of the AC300 + B300 with 350 Solar and recharged from 240 at a bit over 1 hr. I thought this was good but I have never used anything like this nor do i know anything about it but Very happy so far
Very happy with the AC300 and B300. Super fast delivery. This is the second product with have purchased from you. Customer service is fantastic.
I have a modest home using the AC300 with a single B300 and two 350 solar panels at this earl stage (extension cord madness) I am easily at 80% off grid with little to no concerns about all of my home plug in electrical power next stage is integrating the Bluetti into my home power box and a possible second B300 to achieve greater solar storage.
I am delighted with the products they are excellent.
Just a suggestion - it would be good if the two devices connected when you stacked them on each other so the cable wasn’t required. Mainly for my application where it’s in a van and I only need one battery and space is tight
But all up it’s an excellent product thanks?
So happy with the AC300 I bought a second one. Easy to set up and easy to use phone app. Highly recommend this unit.

Yes. Once connected via WiFi or Bluetooth, the BLUETTI App will enable you to control the AC300+B300 remotely, like switching the working mode and upgrading the firmware.
Q5: Can I use it as an uninterruptible power supply (UPS)?A:
Yes. It supports four UPS modes:
1. Standard UPS.
2. Time Control UPS (Pay less for higher electricity consumption).
3. PV Priority UPS (Recommended for regions with sufficient solar energy).
4. Customized UPS.
Q6: How do I connect this to my home main panel?A:
BLUETTI recommends a competent and trained licensed electrician undertake the task. Connect the wires of critical equipment from your house electric panel to BLUETTI AC300 directly.
Q7: What is the UPS switching time?A:There are two types of working conditions of UPS for AC300 system.

Yes, if the solar panels' specs fall in
- 1) Total Voltage: 12-150V.
- 2) Total Power: 2,400W Max. (From the two PV input ports)

No. Also, please do NOT store it in a humid environment for a long time.
Q11: Can it charge and discharge at the same time?A:
Q12: How do I know whether my appliance can work well with the AC300 and B300 combo?A:
Calculate the total wattage of your devices. AC300 should work if the load doesn't exceed its rated 3,000W.
Q13: How long can it run my device?A:
Running time = Battery capacity × DoD × η ÷ Device rated power
DoD refers to Depth of Discharge and η is local inverter efficiency.
For AC300, both DoD and η are 90%. If you run a 1,000W microwave oven with AC300+B300 combo, the running time will be:
3,072Wh × 90% × 90% ÷ 1,000W ≈ 2.5hrs
- 1) The formula is NOT suitable for inductive loads with compressors, like refrigerator, air conditioner, etc.
- 2) The above data is for reference ONLY.
