Question 1

Q1: Is the Apex 300 waterproof?

Accepted Answer

A: No. Please keep it dry during use.

Question 2

Q2: Why are there two types of battery cables?

Accepted Answer

A: Short cable (270mm): Designed for stacking the Apex 300 directly on top of
the B300K for better efficiency and cable management.

Long cable (800mm): Great for users who prefer to place the battery
separately—gives you more flexibility in setup.

Question 3

Q3：What's the maximum capacity I can get with Apex 300?

Accepted Answer

A: You can connect up to 6 batteries, even mix and match models:

● With 6×B300K: Up to 19,353.6Wh (Requires P090A battery cables – short or long
depending on placement)

● With 6×B300 or B300S: Up to 21,196.8Wh (For B300: long P090D cable
recommended; For B300S: P150D to P090D cable needed)

Tip: If stacking more than 3 batteries, consider starting a second stack. Use
long cables when connecting battery #3 to #4 across stacks. Short cables are
more efficient, but long cables offer layout flexibility.

Question 4

Q4: What's new about the Apex 300?

Accepted Answer

A: The Apex 300 builds on the AC300/AC500 with major hardware and software
improvements:

● Streamlined design for easier setup and use

● Smarter control through the BLUETTI app

● One-tap OTA updates for faster upgrades

Note: When paired with B300K, the Apex 300 supports one-step firmware updates
for both units—just 10 minutes. When using B300 or B300S, each unit needs to be
updated separately via the app.

Question 5

Q5: Are there add-ons for the Apex 300?

Accepted Answer

A: Yes. You can customize your system with these optional accessories:

● Hub D1 – Adds DC output ports for running compatible devices

● Charger 1 – Enables fast, on-the-go charging using your car's alternator

● P090D/A battery expansion cables (270mm/800mm) for flexible expansion

● Solar charging cable (MC4 to XT60) for connecting solar panels

● Lead-acid battery charging cable (clamp to XT60) for charging from external
batteries

Tips: These accessories are sold separately, so pick the ones that match your
setup needs.

Question 6

Q6: How to charge the Apex 300?

Accepted Answer

A: You've got multiple options:

● AC charging (wall outlet)

● Solar charging

● Car charging (via cigarette lighter port or alternator using Charger 1)

● Generator charging

● Combined charging (AC + solar)

It's ready for everyday use, off-grid setups, or emergency power.

Question 7

Q7: Can it restart without any grid power (black start)?

Accepted Answer

A: Yes. Even if it's fully drained, the Apex 300 can restart using solar or
other external power sources.

Question 8

Q8: What can I do with the BLUETTI app?

Accepted Answer

A: The app gives you full control and insights, including:

● Remote power on/off

● Real-time monitoring of power usage and battery levels

● Mode switching (AC charging modes, working modes, etc.)

● One-tap OTA firmware updates

● Multi-device management (Apex 300, B300K, Hub A1, etc.)

● Battery health tracking

● Adjustable input power limits

Question 9

Q9: How much solar input can the Apex 300 handle?

Accepted Answer

A: The Apex 300 supports up to 6,400W of solar input when fully equipped:

● Direct input via 2 XT60 ports Each input port supports up to 1,200W (12V-60V*,
20A Max.), totaling 2,400W. For optimal performance, connect your panels in
parallel.

● Charging with SolarX 4K (Optional) The SolarX 4K lets you input up to 4,000W**
from high-voltage solar panels (500V Max.) — perfect for stringing panels in
series. (We recommend using a solar breaker for safety.)

● Combined Setup Use both XT60 ports and SolarX 4K together for a maximum solar
input of 6,400W.

* The 60V limit is based on safety standards (IEC 60364 and ISO 3864).

** At least one B300K is required. For up to 3 B300K, use the included short
battery cables to get the full 4,000W input. Long battery cables limit SolarX 4K
input to 3,000W. A single Apex 300 unit supports up to 3,200W additional input
from SolarX 4K.

Question 10

Q10: How many AC charging modes are there?

Accepted Answer

A: The Apex 300 offers 4 AC charging modes to match your needs:

● Standard (up to 1,440W): Everyday charging at a solid pace.

● Turbo (up to 3,840W): Top up quickly before a trip or during a short power
window.

● Silent (up to 500W): Keep things quiet at night or in shared spaces.

● Custom (Adjustable via app): Set the charging current yourself to control
speed. Ideal when you want to limit power draw or optimize charging for specific
needs.

Question 11

Q11: What does the Extreme Weather Alert do?

Accepted Answer

A: Effortlessly stay protected from severe weather or disasters. Enable the
feature in the app, and the Apex 300 will automatically switch to Emergency
Backup mode when a warning is issued—prioritizing solar and grid charging to
maximize your battery's reserve. It switches back once the alert clears.

Question 12

Q12: How to run Apex 300 units in parallel?

Accepted Answer

A: It's plug-and-play! Just use the appropriate P050A parallel cable to connect
up to 3 Apex 300 units to the Hub A1. They'll automatically enter parallel mode
— no extra setup needed.

Parallel setups scale both power and capacity for heavier loads or extended
backup time:

● Max AC output: 11,520W (3 units)

● Max battery capacity: 58,060.8Wh (3* Apex 300 + 18*B300K)

Question 13

Q13: Is UPS mode supported in parallel setup?

Accepted Answer

A: Yes. Once connected through the Hub A1, just open the BLUETTI app to enable
UPS mode for the entire system. Enjoy seamless backup across all units.
