Charging

AC Charging

1. Consider the specifications of utility, AC outlet and charging cable before setting the Max. Grid Input Current.

Note: The Max. Grid Input Current is set at 10A by default and only works when AC500+B300K connects to the grid. Email to BLUETTI Customer Service for password.

Parameter Setting:

Max. Grid Input Current: 5A, 10A, 15A, 20A, 23A, User-Defined.

Please make sure that Silent mode is turned off and the maximum external switching current conforms to the set value, avoiding accidents.

(2) Plug the AC500+B300K into the wall outlet via the AC charging cable.

Generator Charging

Connect AC500+B300K to the generator via the charging cable*. (* Sold separately.)

Note: BLUETTI recommends an inverter generator that delivers at least 5000W pure sine wave AC power. Voltage and frequency limit: EU/UK: 195.5-253VAC/47-53Hz, AU: 204-264VAC/47-53Hz.

PV Charging

AC500+B300K supports dual PV input with the DC input cable. Connect the solar panels (in series or parallel) to AC500+B300K and CHECK the PV connection on LCD screen.

DC Input Cable Connections:

• DC1 PV+/PV-
• DC2 PV+/PV-

Note: Please make sure your solar panels at each input comply with:

• OCV: 12-150V
• Vmp: 12-150V
• Power: 1500W Max.

Example: Connect three BLUETTI PV350 solar panels in series to DC1 or DC2. BLUETTI PV350: Voc=46.5V, Vmp=37.5V, Current=9.2A Max. Total: Voc=46.5×3=139.5V, Vmp=37.5×3=112.5V, Current=9.2A Max.

The LCD screen shows DC input status:

• DC1 Input Voltage: 139.1 V
• DC1 Input Power: 1200 W
• DC2 Input Voltage: 0 V
• DC2 Input Power: 0 W

OCV: Open circuit voltage, also for Voc. The maximum voltage that the solar panel can produce with no load on it.

Vmp: Voltage at maximum power. The voltage available when the panel is operating at its peak performance output.

The roof panel can also charge the AC500+B300K. If the panel's OCV falls in 150-550V, please use the D300S to lower the voltage. Find details in D300S PV Voltage Step Down Module User Manual.

Car Charging

Connect the AC500+B300K to the vehicle plug-in cigarette lighter port via the DC input cable and car charging cable.

Note: Set 'Others' as DC1/DC2 input source to enable car charging. The Max. input current is 8.2A.

Lead-acid Battery Charging

Connect the AC500+B300K with the lead-acid battery via the DC input cable and lead-acid battery charging cable.

Note: Set 'Others' as DC1/DC2 input source to enable lead-acid battery charging. Clamp the positive connector (red) to the positive battery terminal and negative (black) to the other. The Max. input current is 8.2A.

The lead-acid charging cable is for charging AC500+B300K ONLY.

Dual Charging

Set 'PV' as DC1/DC2 input source to enable AC/Generator + PV Charging.

Set 'Others' as DC1/DC2 input source to enable AC/Generator + Adapter/ Car/Lead-acid Battery Charging.

Turn on 'PV Parallel Enable' to enable excessive PV charging (>1500W, <150V).

Charging can be done via:

• Wall Outlet
• Generator
• AC Adapter
• Solar Panel(s)
• Car
• Lead-acid Battery

Discharging

The AC500+B300K can power various devices for extended periods. Estimated runtimes:

• Fridge: 3-4 Days (700W/24h)
• Microwave Oven: 4-5hrs (1000W)
• Washing Machine: 5.2/10.5hrs (500/1000W)
• Space Heater: 2.5-3.5hrs (1500W)
• Air Conditioner: 6-7hrs (8000Btu)
• Laptop: 110-116 Times (45Wh)
• Electric Vehicle (16A): 11-15 Miles (1800W)
• Smartphone: 285-292 Times (18Wh)

Discharging time (estimated) = 5529.6Wh * DoD * η ÷ (load power). *Take the AC500+2*B300K combo as an example.

Note: DoD refers to the Depth of Discharge, η is the local inverter efficiency. DoD=95%, η=90%. DoD may vary depending on ambient-operating temperature and discharge rate. Load power and charging time are measured in Watt and Hour.

Capacity Expansion

AC500+B300K supports up to 6 expansion batteries for a total of 16,588.8Wh capacity. Connect AC500+B300K via the P150D to P090D cable. For more details, please refer to B300K User Manual.

Connection involves aligning the ports and locking them in place.

UPS

Plug the AC500 + B300K combo to a standard wall outlet or tie them to the grid. When the grid fails, the combo steps in and provides power for connected devices.

Online UPS: Supplies power from the grid to the load through a rectifier and inverter combination regardless of grid power availability or power outages.

Offline UPS: Supplies power from the grid directly to the load when grid power is available. When there is a power outage, it provides power to the load through the backup battery.

Plug-in UPS:

Grid-tied UPS:

The grid-tied UPS should be built by a qualified electrician. Please contact BLUETTI Customer Service for details.

AC500+B300K has 4 UPS modes: Standard, Time Control, PV Priority, and Customized UPS. BLUETTI's UPS mode guide is as follows:

1. The standard UPS mode is good for regions with unstable grid power supply.
2. The Time Control UPS mode will save your electricity bills by setting the charging and discharging time.
3. The PV Priority UPS mode is better for regions with plenty of sunlight all the year.
4. The Customized UPS mode allows you to design your power supply system.

Please refer to BLUETTI Support on YouTube for detailed instructions.

BLUETTI APP

Download the app from App Store or Google Play.

Power Lifting Mode

This mode can be enabled in BLUETTI App. When in this mode, the combo can power high drain pure resistive loads (≤6000W), while the rated output power remains 5000W.

Note: Make sure the combo disconnects the grid and the B300K doesn't overload. The AC500+B300K detects the resistance of devices and adjusts the output voltage automatically. The mode fails when the AC500+B300K drops below 70% of its rated voltage.

Includes heaters, irons or any other devices consisting of heating elements only.
