Frequently Asked Questions

Is the Apex 300 waterproof?

No. Please keep it dry during use.

Why are there two types of battery cables?

Short Cable (270±5 mm): Designed for stacking the Apex 300 directly on top of the B300K for better efficiency and cable management. Long Cable (800±2mm): Great for users who prefer to place the battery separately — gives you more flexibility in setup.

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

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.

What's new about the Apex 300?

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.

Are there add-ons for the Apex 300?

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 ((800±2mm) 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.

How to charge the Apex 300?

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.

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

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

What can I do with the BLUETTI app?

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

How much solar input can the Apex 300 handle?

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.

Can I use third-party solar panels?

Yes, as long as they meet these requirements: ● Total Open Circuit Voltage (Voc): 12V–60V ● Connector Type: MC4-to-XT60, Anderson-to-XT60, or any solar charging cable compatible with an XT60 input Note: Avoid mixing different panel types or ratings in the same array.

How many AC charging modes are there?

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.

What does the Extreme Weather Alert do?

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.

How to run Apex 300 units in parallel?

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)

Is UPS mode supported in parallel setup?

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.
