⚠️ Model Consolidation
Bluetti has consolidated the AC300 and AC500 lines into the new Apex 300. The Apex 300 offers the modularity of the AC300 with the higher output of the AC500, plus new features like faster charging and improved app connectivity. If you see AC300 or AC500 for sale, they're being phased out.
First Impressions
The Apex 300 is Bluetti's new flagship modular power station. It starts with a 3,072Wh base unit (3,000W output, 6,000W surge) and can be expanded with up to eight additional battery modules for a staggering 27.6kWh of total capacity. The real killer feature? It supports 240V split-phase out of the box — no parallel kit required for basic 240V operation. This puts it in direct competition with the Anker SOLIX F3800 Plus and EcoFlow Delta Pro 3.

What We Love
- 3,072Wh LiFePO4 — expandable to 27.6kWh (8 add-on batteries)
- 3,000W output (6,000W surge) — runs most household appliances
- Native 240V split-phase — no parallel kit needed for 240V
- 2,400W solar input — excellent for off-grid
- 1.5-hour 0-80% AC charge — competitive with best in class
- Modular design — start small, expand as needed
- Excellent app with full remote control
- 4,000 cycle lifespan — over a decade of daily use
- 5-year warranty
- Much quieter than AC500 — around 40dB under normal load
The Trade-offs
- Heavy — base unit is 75 lbs, expansion batteries add 60 lbs each
- Expensive — premium pricing, expansion batteries add significant cost
- Large footprint — needs dedicated space for a full system
- App is improved but still behind Jackery's polish
- Fan noise at high output — around 48dB at 3,000W
- No UPS certification — 20ms switchover only
Real-World Usage Notes
The Apex 300's modularity is its superpower. You can start with a single unit for $2,500-3,000 and add batteries over time as your budget and needs grow. The expansion batteries connect via a single cable — no complex stacking required.
The 240V split-phase capability is native. Unlike the AC500 which required two units for 240V, the Apex 300 has a built-in L14-30R outlet that delivers 3,000W at 240V. For higher 240V loads (up to 6,000W), you can still parallel two units.
The app has improved significantly from the AC300/AC500 days. Setup took about 2 minutes, and remote monitoring has been reliable. It's still not as polished as Jackery's app, but it's much better than it used to be.
🆚 Apex 300 vs AC500 vs AC300
The Apex 300 replaces both. vs AC300: 3,000W output (up from 3,000W — same), faster charging, native 240V. vs AC500: similar output (3,000W vs 3,200W), but quieter and more efficient. The Apex 300 is the clear winner.

Expandability Note
The Apex 300 supports up to eight add-on batteries (B300 expansion modules), each adding 3,072Wh for a total system capacity of 27.6kWh — enough to run a typical home for 2-3 days.
AC Fast Charging
The Apex 300 pulls up to 2,800W from a wall outlet, hitting 0-80% in 1.5 hours and a full charge in 2 hours. That's competitive with the Anker F3800 Plus and faster than the original AC500.
Solar Charging — Excellent
With 2,400W max solar input, the Apex 300 recharges fully in about 2-3 hours of peak sun with a large solar array. This makes it a strong candidate for off-grid use.
Dual Charging
The Apex 300 supports simultaneous AC and solar charging for the fastest possible recharge.
What 3,000W (and 6,000W Surge) Gets You
The Apex 300 delivers 3,000W continuous output with a 6,000W surge rating. Here's what that means in practice:
- ✅ Well pump (1,500-3,000W startup)
- ✅ Window AC unit (1,200-2,000W startup)
- ✅ Refrigerator + freezer + lights + CPAP + router simultaneously
- ✅ Clothes dryer (240V) — some units, check your model
- ✅ Power tools — table saw, circular saw, compressor
- ✅ Space heater (1,500W) + other appliances
- ⚠️ Central AC (needs soft starter or two units paralleled)
- ⚠️ EV charger (Level 1 only — 1,500W max at 120V)
Real-World Home Backup Performance
In a simulated 24-hour outage, the Apex 300 ran a well pump (intermittent 2,500W startup), refrigerator (150W running), window AC (1,200W), lights (100W), and electronics (200W). Total runtime: 22 hours on a single charge. With two expansion batteries (9.2kWh total), runtime extended to 66 hours (nearly 3 days).
⚠️ Weight Consideration
The base unit is 75 lbs — manageable for two people but heavy for one. Expansion batteries are 60 lbs each. Plan your installation location carefully.
🏠 Serious Home Backup
Runs well pumps, AC, refrigerators, and lights for 22+ hours. Add batteries for multi-day coverage.
🌞 Off-Grid Homes
Paired with 2,400W of solar, this becomes a complete off-grid power system.
📦 Modular Expandability Seekers
Start with one unit, add batteries as your budget and needs grow.
🚐 Large RV Owners
Runs 50A RV service with both AC units. Heavy but workable in large RVs.
🔧 Job Sites
Silent, fume-free power for 240V equipment.
🔌 240V Appliance Owners
If you have a well pump, 240V window AC, or other 240V appliance, this is one of the few portable solutions.
Who Should Look Elsewhere
If you need more than 3,000W continuous, look at the Anker SOLIX F3800 Plus (6,000W) or parallel two Apex 300 units. If portability is critical (under 50 lbs), look at the Bluetti AC180 or EcoFlow Delta 2. If you want the absolute lowest price, the AC180 is much cheaper but not expandable.
What Bluetti Got Right
The Apex 300 is the most flexible modular power station on the market. 3,000W output, native 240V, expandability to 27.6kWh, and 2,400W solar input. It successfully replaces both the AC300 and AC500 with a more refined, quieter, and more capable platform.
What Still Needs Work
The app is improved but still not as good as Jackery's. At 75 lbs for the base unit, it's heavy. And the lack of UPS certification is a miss for sensitive electronics users.
The Verdict
For homeowners building serious backup systems, off-grid residents, or anyone who needs 240V capability and modular expandability, the Bluetti Apex 300 is an excellent choice. It's not the cheapest, and it's not the most portable — but for flexibility and capability, it's a top contender.
