Short answer: if you are replacing the converter, inverter and breaker panel in one go and want a single-brand, pre-wired 48V system with a touchscreen, the Bluetti RV5 kit is the shorter path. If you already have (or want) a 12V or 24V lithium bank, need to size the inverter, solar controller and batteries independently, or your installer knows Victron, build it from Victron parts. Both routes get you to 5kW-class off-grid power; they get there differently, and the right one depends on the rig and on who is doing the install. Every price in this guide is in one dated section near the end, so you can see exactly how each total is built.
What each route is
The Bluetti RV5 system
The Bluetti RV5 is a 5-in-1 power hub. It replaces the converter, inverter, transfer switch, solar charge controller and DC-DC charger in an RV electrical system with a single 48V unit that puts out up to 5,000W at 120V, with dual MPPT solar inputs, vehicle (alternator) charging and a 48V-to-12V step-down module built in. It is designed to pair with three other Bluetti pieces: the B4810 battery (51.2V, 100Ah, 5,120Wh, with 4.8kWh usable per Bluetti, rated at 6,000 or more cycles to 80%), the Epanel smart distribution panel that replaces a conventional RV breaker panel with monitored AC and DC circuits, and the Epad 10.1-inch touchscreen. Sold together they are the 5kWh RV Kit, which at October prices costs less than buying the four pieces separately. Bluetti rates the system at 5,000W continuous with a 10kW surge, charging from solar, alternator or shore power (shore charge 0 to 80% in 50 minutes), and scalable from 5kWh to 122kWh by adding B4810 modules.
The Victron build
Victron sells components, not a system in a box. A 5kW-class camper build is a MultiPlus-II inverter/charger, a SmartSolar MPPT solar controller, an Orion DC-DC charger for tow-vehicle charging, a Lynx Distributor fused busbar, a SmartShunt battery monitor, a Cerbo GX with a GX Touch display for monitoring, and a lithium bank you size yourself. We package the electronics as the 12V Travel Trailer Power Kit and the 24V Off-Grid Trailer Power Kit; in both, batteries, solar panels and cable are sold separately so you can size them to the rig. At the top of the range, the Expedition Power Kit is the complete 12V system: a MultiPlus-II 12/3000, four 12.8V 200Ah LiFePO4 NG batteries (800Ah), a SmartSolar MPPT 100/50, an Orion XS, a VE.Bus BMS NG, a SmartShunt, a Smart BatteryProtect, the Lynx Distributor, the Cerbo GX MK2 with GX Touch 50 and the interconnect cables.
Side by side
| Item | Bluetti RV5 system | Victron build |
|---|---|---|
| Architecture | 48V, one hub does inverter, charger, solar, DC-DC and step-down | 12V, 24V or 48V, one component per job |
| Inverter output | 5,000W continuous, 10kW surge | 3,000VA MultiPlus-II in our kits; 12/4000, 24/5000 and 48/5000 models available |
| Battery | B4810 modules, 5,120Wh each, stack from 5kWh to 122kWh | Victron LiFePO4 NG in 12.8V, 25.6V or 51.2V, 100 to 300Ah; banks up to 385kWh |
| Solar charging | Dual MPPT built into the RV5 | Separate SmartSolar MPPT (150/70 in the 12V kit, 250/70 in the 24V kit) |
| Alternator charging | Built into the RV5, plus the alternator wiring pack | Orion XS 12/12-50A (12V kit) or Orion-Tr Smart 12/24-15A (24V kit) |
| DC distribution | Epanel replaces the RV breaker panel | Lynx Distributor fused busbar; the existing AC panel stays |
| Monitoring | Epad touchscreen and the Bluetti app; Wi-Fi, Bluetooth, Ethernet | Cerbo GX MK2 with GX Touch 50; VictronConnect app; VRM remote portal |
| What the kit price covers | Hub, distribution, screen and one 5,120Wh battery | Electronics only; batteries extra (see the dated price section below) |
Install effort
The RV5 kit arrives pre-wired, and because the hub takes the jobs of four or five separate boxes there is less to mount and fewer cable runs between components. Bluetti sells four wiring packs for the install, and we stock all of them: the alternator charger pack, the Epanel distribution pack, the solar panel pack and the RV5-to-B4810 battery pack. The part that is more work than a straight inverter swap is the Epanel, because it replaces the breaker panel rather than sitting beside it; if you are adding power to a finished rig, plan for it. If you want to keep your existing panel, the RV5 + B4810 RV Power Bundle is the hub and battery without the Epanel and Epad.
A Victron build is more pieces. Each component mounts separately, the Lynx busbar carries the fusing, and cable size follows the bank voltage you choose. Our kits remove the compatibility guesswork (voltage, current and the VE.Bus, VE.Direct and VE.Can communication are matched so everything shows as one system on the GX Touch), but you still lay the system out. The upside is that it drops into an RV that keeps its existing AC panel and 12V loads untouched. The 24V option uses thinner, cheaper cabling than 12V at the same power, which is why that kit exists for larger trailers and toy haulers that run air conditioning off the battery.
Expandability
Bluetti grows in 5,120Wh blocks. Add a second B4810 and the RV5 manages the pack over closed-loop CAN rather than estimating state of charge; the 10kWh RV Kit is the same system with two batteries from the start. At October prices, though, the 5kWh RV Kit plus a separate second B4810 costs less than the 10kWh RV Kit for the same parts list (the arithmetic is in the price section), so compare both before you order. The ceiling Bluetti quotes is 122kWh. What you cannot do is change the inverter size or the solar controller.
Victron grows in whichever direction you need. The NG batteries scale to a 385kWh bank and can be built as 12V, 24V or 48V; the MultiPlus-II supports parallel and three-phase configurations; a second SmartSolar MPPT can be synchronized over VE.Can (up to 25 units). You can also change one piece without touching the rest. If 3,000VA turns out to be short, a MultiPlus-II 12/4000/160-50 stays on a 12V bank, while the 24/5000/120-95 and 48/5000/70-95 need a 24V or 48V bank; any of them slots into the same Lynx and GX layout.
Monitoring and control
The Epad is the RV5 system's screen: 10.1 inches, 1280 x 800, power and data over a single Bluetti CAN cable from the RV5 or Epanel. It adds two dry-contact relays for scheduling or generator start, inputs for NTC temperature probes and resistive tank-level senders, Wi-Fi, Bluetooth and Ethernet, and a microSD slot for local logging. Tanks, battery and circuits end up on one panel.
On the Victron side the Cerbo GX MK2 is the communication center for the inverter/charger, solar chargers and batteries, with the GX Touch display on the wall and the free VRM portal for remote monitoring from anywhere. Each Victron component also carries its own Bluetooth for the VictronConnect app, so the SmartSolar controller and the Orion charger can be set up from a phone. The kit as sold has nothing equivalent to the Epad's tank-sender inputs.

What the numbers say at October prices: at 5,120Wh, the Bluetti kit with all four wiring packs ($3,813.03) is $1,207.44 less than the Victron 12V kit with two 200Ah NG batteries ($5,020.47 − $3,813.03). At 10,240Wh, the 5kWh RV Kit plus a second B4810 ($4,836.34) is $3,353.16 less than the Expedition Power Kit ($8,189.50 − $4,836.34), though the Expedition kit includes its cables, BMS and BatteryProtect and runs at 12V. Small price moves will not flip those gaps; what can change the answer is the rig, not the price: a 12V bank you want to keep, an AC panel you do not want to replace, or a need for a different inverter size all point to Victron even though it costs more.
Those Victron totals assume drop-in lithium such as the NG batteries, which carry their own internal BMS. A bank built from Victron Smart (non drop-in) batteries needs a Lynx Smart BMS added on top, so treat the figures as the floor for the battery type shown rather than a fixed quote. The Victron totals also do not include fuses, cable or lugs, while the Bluetti wiring packs cover the runs between Bluetti parts. On the Bluetti side, roof solar is the PV100 FX flexible 2-pack, 200W per pack.
Who each suits
- Bluetti RV5 suits a full electrical refit or a new build where you are happy to go 48V from the start; an owner who wants one brand, one app and one screen; anyone who wants tank levels, temperatures and generator start on the same panel as the battery; and a buyer who plans to grow in 5kWh blocks.
- A Victron build suits an RV that keeps its existing 12V system and AC panel; a bank that is already 12V or 24V, or made of batteries with their own BMS; a rig that needs a different inverter size, from the 2,000VA van kit up to 5,000VA; anyone who wants remote monitoring through VRM; and owners or shops who already know the Victron ecosystem.
A decision rule
- Is the breaker panel being replaced anyway? If yes, the RV5 with its Epanel is the natural fit. If no, Victron leaves the panel alone (or look at the RV5 + B4810 bundle, which skips the Epanel).
- Is there a 12V or 24V lithium bank you intend to keep? If yes, Victron. The RV5 is a 48V system built around the B4810.
- Do you need more than 3,000VA, or do you want it in one box? The RV5 gives 5,000W in the hub; Victron gives it with a 48/5000 or 24/5000 MultiPlus-II and a matching bank.
- Who is installing? A pre-wired kit and four wiring packs favor a competent owner; a component layout favors a shop or an owner who has built a Victron system before.
- How will it grow? If the answer is "more battery, same everything else," both work. If it is "different inverter, second solar controller, maybe a generator input later," Victron.
What we'd do
For a fresh build in a trailer that is being wired from scratch, we would spec the 5kWh RV Kit with the four wiring packs and a PV100 FX pair on the roof ($3,813.03 + $296.92 = $4,109.95 at October 11 prices), and add a second B4810 when the first season shows it is needed. For an existing camper with a working 12V system, we would put in the 12V Travel Trailer Power Kit with two 200Ah or 300Ah NG batteries and keep the factory panel. They are two good answers to two different starting points. Browse the whole range in our Bluetti collection.
