Everything You Want, All in One
Power Option for Personalization
Luckily, AC300 owners who are looking for a more powerful inverter don't have to order a new bundle because the 5.000W inverter within AC500 can fulfill their demand without a doubt.

*The charging time is calculated under ideal conditions and for reference ONLY. The specific charging time may vary due to ambient temperature and other factors.
Unparalleled Recharging Experience
* Require a 50A charging cable or tie to the grid.
* Require at least two B300S packs and dual charge via 3.000W solar and 5.000W AC. Or the input rate would be limited to 4.500W with only one B300.
Safe, Smart, And Seamless UPS Backup

I ordered the AC500 AND 2X B300S AND 1X B300K BUT WHEN IT ARRIVED I WAS TOLD THAT I ORDERED THE B300K'S BUT I SENT SCREENSHOTS OF WHAT I ORDERED AND NOW YOU SEND ME A SUBMIT REVEIW OF THE AC500 AND B300S !
When you buy a new car you expect it to start when you turn the key... in this case I got picture and text assuring me that I got a solution with 2 packages.
When I only got 1 of them... a dead box I complained but was assured from bluetti that they managed to trick me to buy a product that does not work if you are not willing to spend another 2000 euro... what a fraud....
AC300 wasn't powerful enough to supply our laundry room, so AC500 brought a nice addition to our autonomous laundry room (2-2.4kW) & water boiler (3kW). We can operate the washing machine AND the drier (or boiler) at the same time, without overloading the unit. Our boiler starts at 3.3kW so it would overload AC300. We also enjoy the extra solar input of this unit.
Careful, it's a bit heavier than AC300. We love both units, but benefit most from this one.
Only downside is the lack of support for B300.
Actually, there is support via a P150D to 90D wire, but it's expensive, and every time we connect a B300 to the AC500 using that wire (direct connection, or via another B300S), we get a beeping sound and a "BMS error" message, which doesn't prevent using the battery. We just need to turn it on manually every morning.
thanks for the great advice and help in choosing the right Fate model, glad to cooperate. Fate answered all my questions and helped me with payments. thanks, I'm very grateful! I will definitely buy more batteries of additional power and a solar battery! power is often cut off in Ukraine, so we really need bluetti now and help us out

Q2: How many B300 packs can be connected to AC500？
A: 4*B300
-
Q3: How many B300S packs can be connected to AC500？
A: 6*B300S
-
Q4: Can B300S and B300 be mixed?
A: Yes. 4 packs in total.
-
Q5: Can I use AC500 alone?
A: No, it's 100% modular and needs to team with B300S/B300 to get its job done.
-
Q6: What is the max charging power of AC500?
A:
1. 3.000W max. with 1*B300
2. 5.000W max. with 2*B300 or more
3. 4.500W max. with 1*B300S (PV+AC)
4. 8.000W max. with 2*B300S or more (PV+AC) -
Q7: Can I use other brands' batteries?
A: No, AC500 is compatible with B300S or B300 ONLY.
-
Q8: What is the power consumption of AC500 when it's off/on?
A:
1. 11W when AC500 is on, DC and AC are off;
2. 30W when AC and DC are on. -
Q9: Do I need an extra cable to connect B300 and AC500?
A: Yes, P150D to P090D is required, you may order it separately in BLUETTI Store.
-
Q10: What is the difference between B300S and B300?
A:
1) Current capacity: 130A for B300S while 75A for B300.
2) ONLY B300S features the automatic heating function.
3) Solar input: 500W for B300S while 200W for B300. -
Q11: How does the heating function work?
A: When the temperature is below 0℃, the battery will be automatically heated once AC or PV charging is activated (input power＞400W).
-
Q12: How to connect AC500 to the main panel ?
A:
Low Voltage Area: Match the transfer switch and smart home panel to the main panel.
High Voltage Area: Match the transfer switch to the main power box. -
Q13: What is the switching time of the UPS?
A: 20ms.
-
Q14: Can I use third party solar panels to charge AC500?
A: Yes, the solar panels must meet the following conditions:
1) Total voltage:12-150V
2) Total power: 3.000W max.
3) With MC4 connectors -
Q15: Can I use rooftop solar panel to charge AC500?
A: Yes, but please note that your solar roof must meet:
1. No micro-inverter
2. Open circuit voltage 12-150V
3. With MC4 connectors
Note: When OCV exceeds 150V, you may use BLUETTI D300S* to step down the voltage to achieve solar charging. -
Q16: Does AC500 support charging and discharging at the same time?
A: Yes.
-
Q17: How long will AC500 run my device?
A: Running time = battery capacity x DoD x η ÷ device rated power DoD: Depth of Discharge, η: local inverter efficiency. For AC500, both DoD and η are 90%.
If you run a 1.000W microwave oven with a AC500 + B300S combo, the running time will be 3.072Wh × 90% × 90% ÷ 1.000W ≈ 2,5 hours
Note:
1) This formula doesn't apply to inductive loads with compressors, such as refrigerators, air conditioners, etc.
2) The above data is for reference ONLY. -
Q18 : Is AC500 waterproof?
A: No, please keep it in a dry place.
-
Q19: Can I use the fusion box in high voltage areas?
A: No.
