Better on capacityBLUETTI RV5 10kWh RV KitTwo B4810 batteries store 10,240 Wh. $5,499Scores 8.0- Surge: 10,000 W on the product page, 2.0 times continuous; the manual gives none
- One battery: the manual puts total load at about 4,320 W with a single B4810
- Derating: the hub derates its load between 113 and 131 °F
- Test: rated at 0.5C charge and discharge at 77 °F; depth of discharge not stated
- Solar: two inputs of 1,800 W and 50 A each, 12 to 50 V, 3,600 W total
- Alternator: PV2 takes 600 W from a 12 V or 1,200 W from a 24 V starter system
- Shore: 120 V at up to 42 A, 5,000 W in Turbo mode, plus a 208/240 V EV charging input
- Transfer: UPS switchover within 20 ms; bypass carries up to 6,000 W and 50 A

Every charger built in, one Battery short
- What it is: a 48 V RV power system of BLUETTI's 5,000 W RV5 hub and one 5.12 kWh B4810 battery
- The trade-off: every charging source in one hub, but full inverter output needs a second battery and solar strings are held to 50 V
- Not checked: inverter efficiency and idle draw, which the RV5 manual does not publish
- Look elsewhere for: split-phase or 50 A pass-through, high-voltage solar strings, or third-party batteries with their own BMS
Strengths
- Solar, alternatorshore and generator charging in one hub
- Fast recharge from shore power
- Self-heatingwater-resistant battery
- Labelled wiring that owners found easy to install
- Grows by adding batteries to the same hub
Drawbacks
- No published inverter efficiency or idle draw
- Full inverter output needs a second battery
- Low solar input voltage limits panel strings
- Single-leg AC output with no split-phase
- Owners report third-party batteries are hard to use

BLUETTI Power Inc., a Nevada corporation based in Las Vegas, sells BLUETTI in the US, and the brand belongs to Shenzhen PowerOak Newener Co., Ltd. of Shenzhen, China.
It sells its panels, batteries and RV systems with a cart at bluettipower.com and on Amazon US through its own store, and its panels are listed at Home Depot, Lowe's, Best Buy and Walmart, partly through BLUETTI's own marketplace stores.
The BLUETTI RV5 + B4810 (store SKU RV5-4-01-SPFUS-00) is a 48 V RV power system made of BLUETTI's RV5 Power Hub and one B4810 LiFePO4 battery, storing 5,120 Wh in all.
The RV5 Power Hub (model RV5 in its manual) combines a pure sine inverter rated 5,000 W at 120 V, 60 Hz and 42 A, two MPPT solar inputs, vehicle charging, an AC charger and a 48 V to 12/24 V DC step-down; BLUETTI's page gives 10,000 W surge.
Each solar input, PV1 and PV2, takes 12 to 50 V at up to 50 A and 1,800 W, 3,600 W in all, and PV2 can instead charge from a vehicle's starter system at 600 W (12 V) or 1,200 W (24 V).
Its AC input takes 120 V shore or generator power at up to 42 A, set in the app from 12 A up to 50 A, charging at up to 5,000 W in Turbo mode, or 208/240 V EV charging at 22 A. When AC input is present the hub passes it through in bypass at up to 6,000 W and 50 A, and its UPS switchover takes 20 ms or less.
The DC output gives 12 V at 100 A (1,360 W) or 24 V at 60 A (1,620 W), and Bluetooth and Wi-Fi link the hub to the BLUETTI app. The hub runs from -4 to 113 °F (load derates up to 131 °F), measures 17.72 x 19.69 x 6.30 in (450 x 500 x 159.9 mm) and weighs about 30.86 lb (14 kg); it cannot be paralleled.
Each B4810 is a 51.2 V, 100 Ah (5,120 Wh) LiFePO4 battery with self-heating, charging and discharging from -4 to 131 °F, 100 A maximum discharge (200 A for 30 s), IP65, 23.94 x 14.96 x 5.71 in and about 101.4 lb (46 kg).
BLUETTI rates the B4810 for 6,000 cycles to 70 percent capacity at 0.5C and 77 °F, and up to 24 connect in parallel, with Edock boxes above eight.
The RV5 box holds the hub, eight M8 wood screws, eight anchors, a drilling template and the manual, and the B4810 manual lists terminal bolts, washers and wood screws with the battery; an Ethernet cable links the two. BLUETTI's warranty table gives the RV5 and the B4810 60 months each and accessories 12 months.
It sells at $2,799.00 on bluettipower.com, where the RV5 alone is $1,299.00, the 5kWh RV Kit (adding the Epanel distribution panel and Epad touchscreen) is $3,699.00, and that kit with two, four or six 100 W panels is $3,999.00, $4,299.00 or $4,599.00.
The Epanel alone is $499.00, and wiring packs run $99.00 to $179.00.
