BLUETTI Apex 300 + B500K + Hub D1 Bundle
3,840W portable power system with 7,884.8Wh of LiFePO4 storage and high-current DC output
Save $589 with bundle pricing and free shipping.
This bundle is built for buyers who need more than a basic portable power station but are not ready for a fixed battery installation. The Apex 300 supplies 120V and 240V AC power, the B500K adds 5,120Wh of battery capacity, and the Hub D1 gives RV, van, marine and off-grid users a practical set of regulated DC connections.
Together, the Apex 300 and B500K provide 7,884.8Wh of nominal storage. That added battery capacity extends runtime; it does not raise the Apex 300 inverter above its 3,840W continuous AC rating. This distinction matters when sizing the bundle for air conditioners, pumps, tools and other high-demand equipment.
3,840W Continuous AC output
7,884.8Wh Combined nominal capacity
120V + 240V Dual-voltage AC operation
700W DC Maximum Hub D1 output
Hub D1 and Hub A1 are different products. The Hub D1 included here adds regulated DC outlets. It does not connect multiple Apex 300 units in parallel. A Hub A1 package is required if you later want to combine two or three Apex 300 units for more AC output.

Why This Bundle Makes Sense
Useful Capacity Without a Fixed Installation
The 7.88kWh battery bank can support essential loads through a long outage, then move with you to an RV, cabin, worksite or another part of the property.
120V and 240V at the Same Time
The Apex 300 can operate 120V and 240V equipment simultaneously, which makes it more flexible than portable systems that force you to choose one voltage mode.
Real DC Power for Mobile Builds
Hub D1 adds up to 700W of regulated DC output, including a 50A Anderson connection rated for up to 600W. It is designed for loads such as refrigerators, pumps, lighting, electronics and other RV or off-grid equipment.
Multiple Ways to Recharge
Recharge from a wall outlet, compatible solar array, vehicle outlet or properly configured generator. The Apex 300 accepts up to 2,400W of solar directly, while the optional SolarX 4K supports higher-voltage arrays and up to 4,000W of solar input.
Expandable Battery Storage
A single Apex 300 supports up to six compatible expansion batteries. Using six B500K batteries brings one Apex 300 system to 33,484.8Wh of nominal capacity.
UPS and App Controls
The Apex 300 supports fast UPS transfer modes and BLUETTI app monitoring over Wi-Fi and Bluetooth. Available functions include power monitoring, settings, firmware updates and system alerts.
What Can It Run?
A single Apex 300 can supply up to 3,840W continuously across its AC outputs. That is enough for many refrigerators, freezers, lights, electronics, sump pumps, power tools and selected 240V loads, provided the combined running wattage and startup demand stay within the inverter limits.
The larger B500K battery changes how long those loads can run, not how many watts the inverter can produce. For motor-driven equipment, check both running watts and startup surge before ordering.
Illustrative Runtime Estimates

|---|---|---|
| Wi-Fi router | 20W | Approximately 335 hours |
| CPAP machine | 50W | Approximately 134 hours |
| Full-size refrigerator | 150W average | Approximately 44.7 hours |
| Large television | 200W | Approximately 33.5 hours |
| Continuous medium load | 500W | Approximately 13.4 hours |
| Continuous heavy load | 1,000W | Approximately 6.7 hours |
| High continuous load | 2,000W | Approximately 3.4 hours |

Runtime estimates use 85% of the bundle’s 7,884.8Wh nominal capacity. Actual results vary with inverter overhead, operating mode, temperature, battery condition, cycling loads, startup surges and device efficiency. Always use the connected appliance’s measured power draw when planning backup time.
Before You Buy
- A single Apex 300 remains a 3,840W inverter even after the B500K is connected.
- The 50A-style AC receptacle does not mean a single unit can continuously deliver 50A. Total AC output is still limited to 3,840W, or about 16A at 240V.
- Hub D1 is for DC output. Hub A1 is the separate accessory used to parallel multiple Apex 300 units.
- Plug-in backup is ready to use after setup. Powering selected household circuits or adding automatic home backup requires compatible integration hardware and professional installation.
- The Apex 300 is not waterproof. Keep the power station, battery and connections dry and follow the installation clearances in the manuals.
- The B500K weighs about 99 lb and the Apex 300 weighs about 84 lb. Plan for two-person handling or a compatible trolley.

Frequently Asked Questions
What is the total battery capacity of this bundle?
The Apex 300 contains 2,764.8Wh and the B500K adds 5,120Wh, for 7,884.8Wh of combined nominal capacity.
Does the B500K increase the Apex 300’s AC output?
No. The B500K increases runtime and stored energy. A single Apex 300 remains limited to 3,840W of continuous AC output.
What does the Hub D1 do?
Hub D1 adds up to 700W of regulated DC output for RV, van, marine and off-grid equipment. Its connections include Anderson, cigarette-lighter, DC5521, USB-C and USB-A output types.
Is Hub D1 the accessory used to parallel Apex 300 units?
No. Hub D1 is a DC power hub. The separately sold Hub A1 package is used to parallel two or three Apex 300 power stations.
Can it power 120V and 240V equipment at the same time?
Yes. The Apex 300 supports simultaneous 120V and 240V output. The total combined AC demand must remain within the unit’s 3,840W continuous rating.
Does the 50A outlet provide 50A continuously?
No. The receptacle format supports system integration and future expansion, but one Apex 300 still supplies a maximum of 3,840W. At 240V, that is about 16A total continuous output.
Can this bundle provide whole-home backup?
It can run many essential household loads, but whole-home suitability depends on the home’s load profile. Direct connection to household circuits or automatic backup requires compatible home integration equipment, proper circuit design and professional installation. That hardware is not included in this bundle.
Are solar panels and solar cables included?
No solar panels are included. The standard Apex 300 package includes AC and car charging cables. PV panels, array wiring and any additional solar adapters or extension leads must be selected for the planned array unless your order specifically lists them.
How much solar can the Apex 300 accept?
The Apex 300 has two native solar inputs rated at up to 1,200W each, for 2,400W total under compatible voltage and current conditions. The optional SolarX 4K supports up to 4,000W and higher-voltage PV arrays.
Can I charge it from a generator?
Yes. The Apex 300 can recharge from a compatible generator through an approved AC charging method. Generator voltage, frequency, grounding and output quality must meet BLUETTI requirements.
How many B500K batteries can be added?
One Apex 300 supports up to six compatible expansion batteries. With six B500K batteries, total nominal capacity reaches 33,484.8Wh. Follow BLUETTI’s cable and battery-mixing guidance for the final configuration.
Can I add more Apex 300 units later?
Yes. BLUETTI supports parallel systems with two or three Apex 300 units and the correct Hub A1 package. A three-unit system can reach 11.52kW of AC output. Hub A1 and additional Apex units are not included here.
Can the B500K be used as a standalone AC power station?
No. The B500K is an expansion battery and does not have its own AC inverter outlets. In this bundle, AC power comes from the Apex 300 and regulated DC power is provided through Hub D1.
Can the system be used outdoors?
The bundle is useful for RV, mobile and off-grid applications, but the Apex 300 is not waterproof. Keep all equipment and electrical connections dry, protected and within the temperature and ventilation limits in the manuals.
How should I plan for the weight?
The Apex 300 weighs about 83.8 lb and the B500K weighs about 99.2 lb. Treat them as separate heavy components, use two-person lifting when needed, and consider BLUETTI’s compatible trolley for frequent movement.
