System capability
From home to off-grid living, the Apex 300 delivers.
Power and expansion
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.
Charging flexibility
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.
Battery and durability
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.
