📝 Manufacturers Note: Charge times from solar assume the maximum possible sunlight using the highest-rated solar panels that each manufacturer recommends.
The faster charging of the AC300 is a great feature and means you can get back online with all the power you need as soon as possible.
However, the DELTA Pro can be charged at a commercial Level 2 EV charging station, meaning that you can recharge almost as quickly.
Cost Of Output Expansion
Both can be expanded by adding more components, meaning increased energy independence. The maximum output that both devices can be “grown” to is approximately 25kWh.
But the cost to do so differs significantly. For me, this difference in their ‘modularity’ is a crucial factor.
The AC300 Expansion Potential
The BLUETTI AC300 can grow from a single unit with a battery that produces 3,000W to a complete home backup system that can generate up to 6,000W with a maximum capacity of 24,576Wh.
The final configuration will include the components listed below:
- 2 X BLUETTI AC300 Pure Sine Wave Inverter.
- 8 X 3,072Wh BLUETTI B300 Battery Backup (4 for each inverter).
This configuration adds substantial costs to the setup, as follows:
| Device | Cost |
| 1 X AC300 PLUS 1 B300 Battery | $3,598.00 |
| 1 X AC300 PLUS 1 B300 Battery | $3,598.00 |
| 6 X B300 Expansion Batteries | $12,594.00 |
| AC-300 Fusion Box | $329.00 |
| Total | $20,119.00 |
The EcoFlow DELTA Pro Expansion Potential
The EcoFlow DELTA Pro can also be linked with other devices to provide an impressive power output. This device can be expanded to 7.2 kW.
The configurations and associated costs to achieve 25kWh capacity are listed below.
| Device | Cost |
| 1 X EcoFlow DELTA Pro | $3,299.00 |
| 1 X EcoFlow DELTA Pro | $3,299.00 |
| 4 X EcoFlow DELTA Pro Smart Extra Batteries | $9,596.00 |
| EcoFlow Double Voltage Hub | $139.00 |
| Total | $16,333.00 |
The Portability Of The Power Supplies
| Length | Width | Height | Weight | |
|---|---|---|---|---|
| AC300 plus B300 | 20.5in (52 cm) | 12.5in (32cm) | 24.6in (101.80 cm) | 127.2lbs (57.6kg) |
| Jackery 500 | 25in (63.5cm) | 11.2in (28.4cm) | 16.4in (42cm) | 99lbs (44.9kg) |
Neither product is light; however, the ecoflow has two advantages.
- It is the lighter machine of the two.
- It has built-in wheels and a handle, making it easier to move around.
The result is that if it is being moved over reasonable surfaces, the DELTA Pro has a degree of portability.
This makes it an extremely versatile power supply that can be connected to the home as a full-time backup or smart energy supply. When you go on holiday, unplug it and take it with you.
In contrast, the AC300 stretches the definition of portable. It weighs more than two bags of cement (if you have ever carried a bag of cement, you know that this is heavy). It is also bulky and realistically needs two people to carry it.
The EcoFlow DELTA Pro Can Charge An EV
Although it cannot provide a full charge, it may be sufficient to charge in an emergency and get you to a charging station.
The EV X-Stream Adapter is a J1772 (Type 1) connector compatible with most EV charge points. These connect the DELTA Pro power station to the EV.
Final Verdict
It’s time to choose a winner, and for the following reasons, my verdict goes to the EcoFlow DELTA Pro:
🏆 It costs less than the AC300.
🏆 Expanding the power to 25kW is over $3,700 less than the Bluetti.
🏆 It produces 3.6 kW compared to the 3 kW generated by the Bluetti.
🏆 It is 28.2 lbs. lighter than the AC300.
🏆 It has built-in wheels and a handle, making it more portable.
🏆 Charge an EV in an emergency and can be recharged at any level 2 EV charger.
None of this is a negative reflection of the AC300, which remains a solid product that does everything it promises on the label.
I would select the Bluetti under the following circumstances:
- If the working conditions required regular and faster recharging, such as construction sites.
- The wireless charging pads are convenient, particularly when the device is used in a remote location.
- With a dedicated RV power outlet, the AC300 would be my choice for use on holiday in the family RV.
