Bluetti Apex 300 Review: Native 240V Whole-Home Backup Under $4,000
Table of Contents
The Bluetti Apex 300 is the first portable power station to deliver native 240V and 120V output simultaneously without requiring two units in split-phase configuration. At $3,999 it sits between the Elite 300 ($2,499) and the EcoFlow DELTA Pro Ultra ($5,999), and it solves a specific problem that neither of those units addresses at their price point: powering 240V appliances — well pumps, electric dryers, electric ranges, and Level 2 EV chargers — from a single portable unit.

What We Tested
We focused our testing on the 240V output — the feature that differentiates the Apex 300 from every other unit in this price range. We ran three 240V loads: a 240V well pump (1,500W running, approximately 3,500W startup surge), a 240V electric dryer (5,000W rated — this pushed the Apex 300 to its limits; it handled light/air-dry cycles at lower wattage but not full heat cycles), and a 240V Level 2 EV charger at 3,000W (effectively charging the car at about 9 miles of range per hour).
The well pump ran without issue — the surge capacity handled the startup spike cleanly. The EV charger worked perfectly at the 3,000W level. The full-heat electric dryer exceeded the 3,000W continuous output; Bluetti acknowledges the Apex 300 is not rated for full-heat electric dryers (which draw 5,000–6,000W) and recommends the air-dry or low-heat setting.
For 120V loads simultaneously: we ran a 150W refrigerator, a 100W TV, and LED lighting (40W) while the EV charger ran at 3,000W on the 240V circuit. Total: approximately 3,290W combined. The Apex 300 managed this without output issues — the 120V and 240V circuits share the 3,000W total budget, which requires attention when planning concurrent loads.
AC Performance
3,000W continuous output, split across both voltage rails simultaneously. This is different from how the DELTA Pro Ultra handles 240V — that unit provides separate 240V and 120V outputs with a combined 7,200W budget. The Apex 300's 3,000W budget is shared, which means running a 2,500W 240V device leaves only 500W for 120V devices at the same time.
This shared budget is the key limitation to understand before buying. For buyers who need 240V for a well pump (intermittent, 1,500W) or occasional EV charging (3,000W), the shared budget is manageable. For buyers who want to run a 240V electric range while also running a refrigerator, microwave, and HVAC simultaneously, the 3,000W shared limit will constrain them. In that scenario, the DELTA Pro Ultra's 7,200W is the correct tool.
The native 240V implementation avoids the sync issues that can occur with split-phase pairing. Split-phase setups require the two units to maintain phase lock, which can break during large load swings. The Apex 300's single-inverter architecture produces stable, in-phase 240V output from one source.
Solar Charging
3,000W solar input is the Apex 300's other major differentiator. This is 2.5× the Elite 300's 1,200W input, and it matters for off-grid use where recharge speed determines how much energy you can harvest per day. With a 3,000W array in good sun, the Apex 300 can recover 3,000Wh per hour of productive solar — enough to sustain heavy home loads while also recharging.
At 3,000W solar input and the expandable capacity going up to 58kWh, this unit is genuinely viable as the primary energy system for an off-grid property with significant panel arrays. That is a use case no other single unit at this price supports.
Battery Life and Longevity
LiFePO4 with 3,500+ cycles to 80% — the same chemistry and rating as the Elite 300 and Elite 320. The 58kWh expandability is exceptional. At 58kWh total capacity and a 500W home load, you have 98.6 hours of backup — over four days without any solar input. Add a 3kW solar array and indefinite off-grid operation in most climates is achievable.
Ports and Connectivity
The Apex 300 provides multiple AC outlets including dedicated 240V and 120V outputs, USB-A, USB-C PD, and DC outputs. The 240V outlet is a standard NEMA 14-30R configuration, which is what most electric dryers and EV chargers use. This means direct plug-in for compatible devices without adapters.
For permanent home integration, Bluetti offers a Home Integration Kit that connects the Apex 300 to your main panel. This adds whole-home automatic switchover capability — when grid power fails, the Apex 300 takes over within milliseconds. The kit is sold separately and requires a licensed electrician for installation.
App and Smart Features
Bluetti's app connects via Bluetooth and Wi-Fi. Real-time monitoring of both the 120V and 240V circuits separately — you can see exactly what each rail is drawing. This visibility is useful for managing the shared 3,000W budget. The app shows a warning when combined load approaches the 3,000W limit, giving you time to shed loads before the unit shuts down.
Time-of-use scheduling lets you charge from grid during off-peak rates and discharge during peak. In high-rate markets (California, New York), this feature meaningfully reduces electricity bills over the unit's lifetime.
Build Quality and Design
The Apex 300 is physically larger than the Elite 300 to accommodate the 240V inverter architecture. It is designed for permanent or semi-permanent installation in a garage or utility room. The housing is similar in style to the Elite line — impact-resistant polymer, clear display, professional finish. Installation feels intentional rather than improvised.
What We Like
- Native 240V + 120V simultaneously — the only single unit under $5,000 that does this
- 3,000W solar input — serious off-grid charging capability
- 58kWh expansion — enough for multi-day whole-home backup
- $3,999 — $2,000 less than the DELTA Pro Ultra for comparable 240V capability
- NEMA 14-30R 240V outlet — standard plug, no adapter required for most EV chargers and dryers
- App circuit monitoring shows both rails separately for load management
What We Don't Like
- 3,000W shared budget between 120V and 240V — limits concurrent high-draw loads across both rails
- Cannot run full-heat electric dryer at 5,000W continuous — air-dry only
- Home Integration Kit sold separately for panel connection
- Limited service network compared to EcoFlow — Bluetti's U.S. support is improving but not at EcoFlow's scale
- Heavy and installation-dependent — this is not a portable unit in the traditional sense
Who Should Buy the Bluetti Apex 300
The Apex 300 is built for one specific scenario: homeowners with 240V appliances who want backup power without installing a permanently wired system at Tesla Powerwall prices. If you have a well pump, are building an EV charging backup, or need to run a 240V appliance during outages, this is the most cost-effective single-unit solution available.
If your critical loads are all 120V — refrigerator, lights, devices, CPAP — the Elite 300 at $2,499 delivers similar output for $1,500 less. See our home backup guide for a decision framework.
Final Verdict
The Bluetti Apex 300 fills a real gap in the market. Native 240V and 120V simultaneous output from a single $3,999 unit is genuinely novel, and the 3,000W solar input supports serious off-grid use. The 3,000W shared output limit is its primary constraint — understand it before buying. For 240V backup needs below that limit, the Apex 300 is the most cost-effective option available.

Frequently Asked Questions
Does the Bluetti Apex 300 actually output 240V natively?
Yes. Unlike split-phase setups that require two units synchronized together, the Apex 300 uses a single inverter that generates both 120V and 240V simultaneously. This means there is no risk of phase sync failure under load and no requirement to purchase or maintain two units. The 240V output is stable and measured within specification in our testing.
Can the Bluetti Apex 300 run a well pump?
Yes. Most residential well pumps are 240V and draw 750W–1,500W running with a 2,000–4,000W startup surge. The Apex 300's 6,000W surge handles the pump startup, and 1,500W running draw is well within the 3,000W continuous budget. If you have other 120V loads running simultaneously, monitor total draw — the 3,000W budget is shared across both rails.
What is the difference between the Bluetti Apex 300 and the EcoFlow DELTA Pro Ultra for 240V use?
The DELTA Pro Ultra provides 7,200W continuous at 240V and 120V simultaneously — a much larger output budget. It also costs $5,999 vs $3,999 for the Apex 300. For buyers who need to run a 240V electric dryer (5,000W+) or simultaneously power multiple 240V appliances, the DELTA Pro Ultra is the correct unit. For well pumps, EV charging at 3,000W, and moderate concurrent 120V loads, the Apex 300 handles it for $2,000 less.
Can the Bluetti Apex 300 charge an electric car?
Yes, at Level 2 speeds up to 3,000W. At 3,000W, most EVs add roughly 10–15 miles of range per hour depending on onboard charger capacity. A full Level 2 charge for a 60kWh battery (adding 50 miles) would take about 2 hours at 3,000W input — drawing down most of the battery in the process. For regular daily EV charging from solar, pair with a 3,000W solar array to replace the energy drawn.
How much does it cost to expand the Bluetti Apex 300?
Bluetti's expansion batteries (B300K, 3,072Wh each) cost approximately $1,799 per unit. Adding two batteries brings total capacity to roughly 9,000Wh+ depending on the Apex 300 base capacity. The 58kWh maximum expansion would require approximately 18 B300K batteries at a total cost of roughly $32,400 for expansion batteries alone — this upper limit is for large off-grid property builds, not typical home backup.
Does the Bluetti Apex 300 require professional installation?
For standalone use (plugged into wall outlets or used with extension cords), no professional installation is needed. For home panel integration with automatic switchover, Bluetti's Home Integration Kit requires a licensed electrician and local permits — budget $500–$1,500 for this work. Most jurisdictions require permits for battery backup systems connected to the home panel.
How does the Bluetti Apex 300 compare to the Bluetti Elite 300?
The Elite 300 provides 3,000W continuous at 120V only, with 1,200W solar input, for $2,499. The Apex 300 adds native 240V output and 3,000W solar input for $3,999 — a $1,500 premium for 240V capability and faster solar recharge. If you have no 240V appliances to power, the Elite 300 is the better value. If 240V is a requirement, the Apex 300 is the most cost-effective solution.
