The BLUETTI RV5 and EcoFlow's Power Kits are the only two 48V RV power systems you can buy as a plug-together set — hub, battery module, distribution panel and control screen designed by one brand to talk to each other over a data bus. Architecturally they do the same job the same way, so the decision comes down to three things: what each rung of the ladder costs on the day you order, how far up the ladder you need to go, and how many ways you want to put energy in. We sell BLUETTI and we do not sell EcoFlow, which is exactly why the competitor numbers below sit in a table with a date and a link to their own page.
What a 48V modular RV system is, and what it replaces
A conventional RV electrical build is a pile of separate boxes: a converter to charge the house bank from shore power, an inverter to make 120V, a transfer switch to decide which source feeds the panel, a solar charge controller, and a DC-DC charger so the alternator can contribute while you drive. Somebody has to size all of it, fuse all of it and make the pieces agree with each other.
Both of these systems collapse that pile into one hub. The BLUETTI RV5 is a 5-in-1 hub — inverter/charger, dual MPPT solar, vehicle (alternator) charging and a 48V DC step-down module — rated up to 5,000W at 120V, and it is the control centre of the system. EcoFlow's listing for their Power Hub says: "The heart of Power Kits with a 3600W AC Output • 5 components in 1, with 2 MPPT solar chargers, 1 • DC-DC battery charger with MPPT, 1 Inverter-charger, and 1 DC-DC converter • Built-in Wi-Fi and Bluetooth • Direct 2400W AC outlet". That is the same idea, described in their own words, and it is a fair description of what both brands are selling.
The other reason both sit at 48V rather than 12V is current. The same watts at four times the voltage means roughly a quarter of the amps, which means smaller cable, smaller lugs and lower losses down the length of a fifth wheel. We went through that trade in more detail in our answer on 48V RV systems versus 12V.
The pieces, side by side
On our side the battery module is the B4810: 51.2V, 100Ah, 5,120Wh of LiFePO4, which BLUETTI states as 4.8kWh usable, rated at 6,000 cycles or more to 80% capacity, stackable, and talking to the hub over closed-loop CAN so the RV5 reads real state of charge instead of estimating from voltage. It is $1,498.99 on our store. The Epanel at $498.99 takes the place of the conventional breaker panel with smart, monitored circuits, and the Epad at $398.99 is the 10.1-inch, 1280 × 800 touchscreen that runs the system over a single CAN cable. The Epad is the piece we point out most often on the phone, because it carries two dry-contact relays (NO/NC/COM) for scheduling or generator start plus inputs for temperature probes and resistive tank senders — tank levels and loads on one screen is not something most RV systems do.
EcoFlow's equivalents are their Power Hub, their 48V LFP batteries and their screen. Their Power Kits listing says: "Plug-and-play for simple assembly • Compact, integrated design, all-in-one inverter hub • Save space with stackable batteries • 48V system, a safer, smaller power solution • Real-time and remote smart controls". We have no reason to argue with any of that.
The price ladder
This is the part nobody publishes side by side, so here it is with a date on it. Each row is the closest like-for-like rung: the hub on its own, a 5kWh system, a 10kWh system, and a single 48V battery module.
| Rung | BLUETTI (ours) | EcoFlow (theirs) |
|---|---|---|
| Hub only | RV5, 5,000W 120V — $1,298.99 | Power Kits Power Hub, 3600W AC Output — $2,998.00 |
| 5kWh system | 5kWh RV Kit: RV5 + B4810 + Epanel + Epad — $3,598.99 | 5kWh Power Kits — $7,999.00–$8,699.00 |
| 10kWh system | 10kWh RV Kit: RV5 + 2x B4810 + Epanel + Epad — $5,998.99 | 10kWh Power Kits — $12,499.00–$13,199.00 |
| One 48V battery module | B4810, 5,120Wh — $1,498.99 | Power Kits 5kWh LFP Battery — $4,599.00 |
| Entry kit vs our 5kWh kit | 5kWh RV Kit — $3,598.99 | 2kWh Power Kits — $4,747.00–$5,146.00 |
| Base Power Kits bundle | — | EcoFlow Power Kits — $6,499.00–$6,899.00 |

Read the bottom rows literally rather than as a slogan. EcoFlow's entry 2kWh Power Kit and our 5kWh RV5 kit both sit in the table above, dated, each with a link to the page the figure came from. Compare the two cells, follow the links, and draw your own conclusion about what that means for your build.
Kit or parts, on our side
One thing worth knowing before you add to cart. Our 5kWh kit at $3,598.99 is $96.97 less than buying the same four parts singly at $3,695.96, so the kit wins. Our 10kWh kit at $5,998.99 is the other way round: the same parts bought individually come to $5,194.95, which is $804.04 less than the kit. We wrote that up in full in our piece on the RV5 kit versus buying the parts separately, and we would rather you knew than found out afterwards.
Charging inputs: EcoFlow is ahead here
This is the clearest win on their side of the table, and it is worth saying plainly. EcoFlow's Power Kits listing says: "4 Charging methods include up to 4800W solar, 1000W alternator, 3000W shore power, and 1800W Smart Generator input." Four named sources with published wattage for each, including a Smart Generator the hub can start on its own. The RV5 charges from solar over dual MPPT, from the vehicle alternator, and from shore power as an inverter/charger, and the Epad's dry-contact relays give you a generator-start output to wire up yourself — but our listing does not publish a per-input wattage figure for each path the way EcoFlow's does, and we are not going to invent one for you. If your build leans on a generator, or on very large solar arrays, EcoFlow has documented that path further than we can document ours.
For roof solar on our side, the usual starting point is the PV100 FX flexible 200W two-pack at $298.99, which follows an RV roof curve without adding much weight up high. Stack more as the roof allows.
The rungs we do not have
Our kit line stops at 10kWh. EcoFlow's does not, and their larger systems carry capability claims we cannot match with a product because we do not sell one.
| EcoFlow product | Price | What their listing claims |
|---|---|---|
| EcoFlow 15kWh Power Kits | $16,999.00–$17,699.00 | The top of their modular kit line; we have no 15kWh kit |
| Power Kits 5kVA 48V Power System | $8,246.00–$8,296.00 | Their listing says: "High 5kVA output power, to run 2 × 13500 BTU rooftop a/c units at the same time" and "As quiet as 48 dB" |

We are quoting those claims, not endorsing them — we have not tested a 5kVA system, and neither of those figures is ours to stand behind. But if you are running two rooftop air conditioners off the battery bank, that is the listing you should be reading, not ours.
Install effort and who has seen one before
Both systems are genuinely plug-together by the standards of RV electrical work: pre-matched cables, a hub that has already sized the relationships between charger, inverter and controller, and a battery that communicates rather than being guessed at. The install labour difference between them is small. The difference that is not small is how many installers have laid hands on one. EcoFlow is the bigger brand here, and more installers have seen a Power Kits rig, so if you are hiring the work out you are more likely to find a shop that has already wired one. The RV5 system is the less familiar of the two on this side of the counter. If your installer has never seen either, budget reading time either way; if your installer already has an EcoFlow build behind them, that is a real advantage and you should weigh it. For a wider view of how both compare to a component-by-component build, our RV5 versus Victron piece covers the DIY end of the same question.
A decision rule
- You need more than 10kWh, or you need a generator the system starts by itself. Go EcoFlow. We do not have a rung above 10kWh and we do not have their Smart Generator integration.
- You want two rooftop air conditioners running off the bank. Read EcoFlow's 5kVA listing and hold them to their own wording.
- You are hiring an installer who has already built a Power Kits rig. Familiarity is worth money. Let them build what they know.
- You want 5kWh or 10kWh, a 5,000W 120V inverter, and a single screen with tank and temperature inputs. That is the 5kWh or the 10kWh RV5 kit, and the price table above is the reason people choose it.
- You are building up over two or three seasons. Either works, because both stack batteries. Start with the hub and one module and add the second when the roof solar justifies it.
What we'd tell a customer on the phone
Most people calling about this are not choosing between two philosophies, they are choosing between two quotes for the same trailer. So we ask three questions: how much usable energy do you actually need overnight, is there a generator in the picture, and who is doing the install. If the answer is 5 to 10 kWh, no generator, and either you or a competent shop doing the wiring, the RV5 ladder does the job and the numbers in the table are what they are. If the answer involves 15kWh, an auto-start generator or two air conditioners, we will tell you to go read EcoFlow's pages, because we would rather lose the sale than sell you a system that tops out below your load. You can see the whole BLUETTI range we do carry at our BLUETTI collection.
