Quick Summary
When it comes to the EcoFlow Delta Pro vs. Bluetti EP500 (& Pro) showdown, the Bluetti EP500 Pro emerges as the champion. Here’s why:
- Impressive single-unit battery capacity with capable inverter size
- Online UPS function performs flawlessly with sensitive electronics
- Incredible amount of solar input and all the ports you can need, including 30A AC and DC outlets
But don’t write off the other units quite yet. They both hold their own, with the EcoFlow Delta Pro giving the EP500 Pro a true run for the money.
If you want to find maximum battery capacity, Bluetti’s 10.2kWh limit doesn’t hold up to EcoFlow Delta Pro’s 21.6kWh. The Delta Pro also packs a bigger inverter, with 3.6kW. The EP500 sits in the back row in this category with a 2kW, but the EP500 Pro hits the middle at 3kW. All can be doubled up for more power.
The UPS function of both Bluetti solar generators is unbeatable. But EcoFlow power stations like the Delta Pro have a 30ms EPS function that’s similar. It’s just not a quick enough UPS transfer time to keep some computers going without a reboot.
And you’re going to find the right ports on the Delta Pro or EP500 Pro, including a 30A AC output and 30A DC output. The EP500 (non-Pro) skips the 30A AC, providing yet another reason it can’t handle the top spot.
The list of other features, company support, app control, and warranty coverage is nearly identical across the EcoFlow Delta Pro and the Bluetti EP500 Pro. The Bluetti wireless charging pads a nice cherry on top, if you’re using the device somewhere it’s useful.
You can’t go wrong with the EcoFlow Delta Pro. But if you’re alright with less modular expansion, the EP500 Pro pushes beyond with its UPS function and single-unit design. The Bluetti EP500 (non-Pro) brings a good size battery, but lacks 30A AC output and a powerful inverter.

EcoFlow Delta Pro vs. Bluetti EP500 (& Pro): The Detailed Comparison
It’s time to dig into the details to see how this solar generator comparison plays out. Then you can see which fits your needs the best.
Battery Breakdown
When it comes to battery capacity, the EcoFlow Delta Pro and the Bluetti EP500 (and its Pro variant) are heavyweights in the solar generator arena. At first glance, the EP500 comes out ahead with a larger battery. But there’s more to the picture.
The EcoFlow Delta Pro boasts a solid 3,600Wh battery capacity. Think of this as a large fuel tank, ready to power your home essentials during an outage. What’s most impressive is its ability to expand. The EcoFlow modular setup means you can add extra juice as needed, with up to two external batteries per unit. The maximum system can ramp up to a whopping 21,600Wh, including:
- Two Delta Pro main inverter units (3,600Wh x 2 = 7,200Wh)
- Four Delta Pro Smart Extra Battery units (3,600Wh x 4 = 14,400Wh)
Note: You may notice EcoFlow claims 25kWh as the Delta Pro max capacity. This includes power generated by the EcoFlow Smart Dual Fuel Generator. This is a great device to add to the Delta Pro that does add hours of power, but it’s not a true part of the battery capacity.
On the flip side, the Bluetti EP500 and EP500 Pro offer a heftier 5,120Wh right out of the box. However, they don’t support additional external batteries. It’s like getting a sports car with a big engine but no room for extra fuel tanks. You’re capped at a maximum of 10,240Wh.
Since both of these have a battery over 3kWh, you can likely get 30% back through the solar generator tax credit.
What’s nice about Bluetti’s setup is that even though it’s capped at 10.2kWh, that’s just with two units. To get to the Delta Pro’s maximum battery size, you need six different units working together.
How much energy is this for your needs? That depends. 5,000Wh (5kWh) can charge a phone nearly 100 times. Or it can run a home fridge at a consistent 200W draw for more than 20 hours. By adding a charging source like solar or a fuel generator, you can extend these time greatly.

Verdict: While the Bluetti starts strong with higher initial capacity, the EcoFlow wins on scalability. It’s a choice between a robust standalone unit against a flexible, expandable system. The EP500 and EP500 Pro are identical in this category.
| Feature | EcoFlow Delta Pro | Bluetti EP500 (& Pro) |
| Battery Capacity | 3,600Wh | 5,120Wh |
| Extra Batteries (external) | 3,600Wh | None |
| Maximum Battery Capacity | 21,600Wh (2 units + 4 batteries) | 10,240Wh (2 units) |
| Battery Chemistry | LFP / LiFePO4 | LFP / LiFePO4 |
| Battery Cycles with 80% | 3,500 | 3,500 |
Inverter Inspection
When it comes to large power stations for home use, the AC inverter is an essential element. It converts the battery’s DC power into AC power needed to power lots of household devices.
The larger the AC inverter, the more power can rush out of the system at one time. If you need to use more power than your AC inverter can offer, it’s not going to work out. It doesn’t matter how much energy you have coming in from solar panels or stored in the battery.
Here’s the breakdown of how these three devices stack up:
- EcoFlow Delta Pro: 3,600W
- Bluetti EP500 Pro: 3,000W
- Bluetti EP500: 2,000W
The Delta Pro is the heavyweight of the bunch, with the EP500 Pro right on its heels. The regular EP500 lags behind though, with just 2,000W of AC power. This inverter size is one of the main differences between the Bluetti EP500 and the EP500 Pro.
All of these devices have peak power that can double the output for brief periods. This is useful for quick startup surges, but shouldn’t be relied on for long-term use. EcoFlow X-Boost allows for longer peak usage, but it does so by lowering the voltage. This means that sensitive electronics can’t use it, and ones that can – like things with electric motors – will run slower than they should. It’s another unique feature from EcoFlow power stations.
Overall, if AC power is a big deal to you, shy away from the normal EP500. The 3,000W of the EP500 Pro is suitable for a lot of needs, with the 3,600W of the EcoFlow Delta Pro stacking on even more power.
For those that want to power a whole house or use heavy-duty appliances like an air conditioner or dishwasher with an electric drying function, consider getting two main units of the Delta Pro or the EP500 Pro. By using these together in a split phase configuration, you can double up the AC inverters to create a 240V output and tackle major electrical demands.
Verdict: EcoFlow Delta Pro comes out as the clear winner in the inverter category, with 3,600W. The Bluetti EP500 Pro is a close second with 3,000W AC output, but the Bluetti EP500 (non-Pro) version is the worst in the group, struggling behind with a 2,000W inverter.
Serious AC users should consider doubling up the Delta Pro or EP500 Pro units to get 7,200W to 6,000W of AC power.
| Feature | EcoFlow Delta Pro | Bluetti EP500 (& Pro) |
| AC Output (per unit) | 3,600W | 2,000W Pro 3,000W |
| Peak AC Output | 7,200W | 4,800W Pro 6,000W |
Solar Input, AC Charging, and UPS/EPS
The charging rate specs for this solar generator comparison between the EcoFlow Delta Pro vs. Bluetti EP500 are all over the place.
EcoFlow is acceptable all-around, but not spectacular. The EP500 Pro is the best of the bunch and is a big reason why it takes the top spot. The EP500 (non-Pro) has very slow AC charging rates that can be a serious pain point for some uses.
Solar Input
For a lot of people, the solar charging rates for solar generators are crucial. It’s an aspect that you really can’t expand. Even if you don’t think you want to max out the solar right now, it can be a real headache down the road when you realize that the insufficient solar input makes you want a new device.
EcoFlow Delta Pro has 1,600W of solar input. Considering its battery size of 3,600Wh per unit, this can recharge in less than 3 hours. This is perfectly acceptable, although it does get a little more challenging with extra batteries. This is another good reason to get a second main Delta Pro unit instead of just an extra battery.
On the Bluetti side, you’re faced with 1,200W of solar input for the EP500. The EP500 Pro doubles it up, providing two 1,200W inputs, for 2,400W total solar. That 2.4kW is a very respectable rate. Compared to its 5.1kWh battery, you’re looking at less than 3 hours for 30% more battery than the EcoFlow. The only catch is that it has 12A max, so make sure to find solar panels with a similar spec. Max out the series connections because the voltage can go up to 150V.
Overall, the EP500 Pro knocks solar charging out of the park, while the other two options are mostly suitable without being exceptional.
AC Charging
The AC charging rates for the EcoFlow Delta Pro vs the Bluetti EP500 follows a very similar path.
The EP500 Pro is incredible, with 3,000W of AC input from a standard 120V outlet. This will bring its battery to full in around 2 hours, lightning fast for a large power station like this.
The EP500 is another story entirely. It has a measly 600W AC charging, taking nearly 10 hours to recharge this power station from a standard AC outlet. For some people, this is a good reason to run away.
The EcoFlow Delta Pro AC charging is a two-sided coin. Its standard charging is 1,800W, which is fine for the one battery and still decent if you stack on EcoFlow Smart Extra Battery units. And if you want to ramp it up, you can get an adapter that will suck in a 240V AC line, jumping up to 3,000W charge rate.
Once again, here the EP500 Pro hits the nail on the head. The Delta Pro is very respectable, but the regular EP500 is surprisingly low.
Bypass, EPS, and UPS Functions
All three units offer bypass or pass-through AC power. This means that they’ll simply feed your AC charging straight through without filling up the battery. Why would you want this? To use these power stations as a small backup system for certain electronics.
But the way these pass-through functions actually work when power cuts out is where the bread meets the butter.
Universal power supply (UPS) function is key for some people. This is what allows you to keep your computer, TV, and internet network running, even if the grid fails and you switch over to battery power. The faster it can make the switch, the better.
Both the EP500 and EP500 Pro excel as a UPS device. They have a true online UPS function that means there is zero downtime in an outage. Plus, there is a full suite of UPS settings and functions for both of these units.
The Delta Pro has a 30ms transfer time and is marketed as an emergency power supply (EPS). And that’s because it’s switchover from AC input to battery backup is a little slow for sensitive electronics, not keeping up with true UPS function. It’s possible that your computer, TV, or other vital electronics will reboot if this happens.
So while they all have pass-through charging, either one of the Bluetti EP500 is superior to the EcoFlow Delta Pro as a UPS device.
Verdict: The Bluetti EP500 Pro is the best all-around for charging inputs and UPS function. It has the most solar, matches the DP AC rate, and has true online UPS. The EcoFlow Delta Pro has reasonable charging specs, but its 30ms EPS switchover is a little lackluster. And the regular (non-Pro) EP500 struggles to keep up with either option, although it does still offer a 0ms online UPS function.
| Feature | EcoFlow Delta Pro | Bluetti EP500 (& Pro) |
| Solar Charging Rate | 1,600W | 1,200W Pro 2,400W (1,200W x 2) |
| AC Charging Rate | 1,800W @ 120V 3,000W @ 240V (need adapter) | 600W Pro 3,000W |
| Pass-Through AC Charging | Yes | Yes |
| EPS/UPS Function | Yes, 30ms | Yes, online UPS (0ms) |
The Rest of the Lineup: Ports, Charging Pads, Weight, and Warranty
In the final section, let’s delve into the remaining specs that round out these power stations’ profiles. Here is all about convenience and support. This includes AC outlets, 240V capabilities, USB ports, wireless charging, app connections, warranties, weight, and dimensions.
Let’s start by talking about the differences in the ports:
- 30A AC and DC outlets on the EP500 Pro and Delta Pro, but no 30A AC on the EP500 (non-Pro)
- Two USB-C outlets on the EP500 Pro and Delta Pro, but only one on the EP500
- Two wireless charging pads on both EP500 and EP500 Pro, but none on the Delta Pro
As far as ports go, the Delta Pro and EP500 Pro comparison is as close as it gets. They both have five AC outlets with one being a high-amp outlet. They both have another 30A DC outlet, which is great for campervan and RV use. EcoFlow’s is a universal Anderson port, while Bluetti’s is a proprietary adapter that goes to XT-60, then from XT-60 to Anderson. A bit more convoluted.
For app connection and warranty coverage, it’s basically identical across the board of the EcoFlow Delta Pro vs. Bluetti EP500 battle. They both have lots of app connections and an impressive 5-year warranty coverage. Make sure to register your purchase right away to get the full 5 years from EcoFlow.
The last category for weight and dimensions looks like an EcoFlow win. But that’s because the Bluetti EP500 has a much larger battery. This isn’t an apples-to-apples comparison.
In general, the Bluetti units are a lot taller and heavier individually. They do have wheels to get around easily, but lifting into a vehicle or RV is a two-person job for most people. But using a lot of different EcoFlow units together can have a higher total weight and take up more space.
It’s really about what works best for you. Can you handle a device that’s over 150 lbs (68 kg)? Do you have space for one that’s tall? Then Bluetti. But if you want a more manageable unit at 99 lbs (45 kg) that can be lined up or stacked, then EcoFlow Delta Pro is the right call.
Verdict: This is nearly a tie between the Delta Pro and EP500 Pro, but the Bluetti wireless charging pads push the EP500 Pro over the top. The EP500 (non-Pro) sits behind without a 30A AC outlet, but is identical in everything else. The single unit weight of the Bluetti might be too much to deal with, especially lifting off the ground.
| Feature | EcoFlow Delta Pro | Bluetti EP500 (& Pro) |
| AC Outlets | 1 x 30A and 4 x 20A | 4 x 20A Pro = 1x 30A and 4 x 20A |

The Final Verdict: EcoFlow Delta Pro vs. Bluetti EP500 Pro
Let’s just get one thing straight out of the gate. The Bluetti EP500 (non-Pro) doesn’t hold up against the other two, including the Delta Pro and EP500 Pro. It has a good size battery and lots of ports, but lacks a powerful inverter and has a very low AC charging rate. It’s UPS function is a notable highlight, but overall, the EP500 isn’t in the same ballpark.
The comparison between the EcoFlow Delta Pro and the Bluetti EP500 Pro is a very close race. And here’s generally how it breaks down:
- Delta Pro wins with the most modular battery expansion, but Bluetti wins with highest single-unit battery capacity
- Delta Pro has highest AC output, but EP500 Pro is closely behind
- Bluetti brings more solar input and faster AC charging from regular 110V outlet
- Bluetti wins with a very impressive online UPS function (available on both EP500 options)
- Both have 30A outlets for AC and DC, but Bluetti features wireless charging pads
- Both have 5-year warranty coverage and excellent app control/monitoring
- EcoFlow is smaller and lighter, but that’s with a smaller battery and the need for more external parts
- Bluetti has all you need in one unit, but it’s rather heavy
So what’s the right answer? What to get if you’re considering the EcoFlow Delta Pro and the Bluetti EP500 Pro?
This comes down to two different functions. For those who want the most battery capacity and a unit that they can lift more easily to bring anywhere, the EcoFlow Delta Pro is the one to pick.
But if up to 10,240Wh is enough battery and you want a true UPS device that’s not as portable, then Bluetti EP500 Pro takes the cake. When you add in the wireless charging pads and more robust solar inputs, it pulls even further away from the competition.
Overall Verdict: With online UPS function, impressive solar inputs, AC & DC high-amp outlets, and two wireless charging pads, the Bluetti EP500 Pro wins as the best of this bunch. For those that need more than 10,240Wh of battery and don’t mind a slower solar recharge rate, the EcoFlow Delta Pro is the right call.
