What Size BLUETTI Do I Need for My RV?

A five-step sizing method for choosing a BLUETTI power station for an RV, with usable capacity, output and solar-refill figures for the main BLUETTI stations we carry.

To size a BLUETTI for an RV, you need two numbers: how many watts you run at the same time, and how many watt-hours you use in a day. The first one sets the output you need. The second sets the capacity. This guide walks through both with simple math, then lines them up against the main BLUETTI stations we carry. It finishes with the solar needed to refill each one.

Step 1: List what you will run

For each device, multiply its watts by the hours it runs in a day. The watts are on the label or in the manual. A compressor fridge is the exception, because it cycles on and off. Use the maker's daily figure for it instead. Here is an example day. The fridge figure is ICECO's published one. The other two are placeholder values, so swap in your own.

Load (example) Watts × hours Wh per day
ICECO VL45ProS 12V fridge ICECO lab figure: 0.510 kWh per 24 h 510
Laptop (example) 60W × 3 h 180
LED lights (example) 20W × 5 h 100
Total 790

Step 2: Turn rated Wh into usable Wh

You never get a station's full rated capacity at the outlet. Inverter losses and the station's own draw take a share. We plan with usable Wh ≈ rated Wh × 0.85. That is our working assumption, not a BLUETTI figure. BLUETTI's own runtime formulas use a depth of discharge of 90–95% and an inverter efficiency of 85–93%, depending on the model, and a self-consumption of about 10W on the Premium stations. Our 0.85 sits within that range for most loads.

Step 3: Match it to a station

Station Rated Usable (×0.85) Days on the 790 Wh example AC output
Pioneer Na 900Wh 765Wh 1.0 1,500W
Premium 100 V2 1,024Wh 870Wh 1.1 1,800W
FridgePower 2,016Wh 1,714Wh 2.2 1,800W
Premium 200 V2 2,073.6Wh 1,763Wh 2.2 2,700W
AC200P L 2,304Wh 1,958Wh 2.5 2,400W
Apex 300 2,764.8Wh 2,350Wh 3.0 3,840W
Elite 320 3,200Wh 2,720Wh 3.4 1,800W
Apex 300 + B300K 5,529.6Wh 4,700Wh 5.9 3,840W
Apex 300 + B500K 7,884.8Wh 6,702Wh 8.5 3,840W

Days = usable Wh ÷ 790. The AC output figures are BLUETTI's continuous ratings, except the Elite 320's, which comes from our listing. Your total will be different from our example, so divide by your own number.

Step 4: Check the output, not just the capacity

Capacity is how long a station runs. Output is what it can run at all. Add up everything you might run at once, and make sure the total stays under the station's continuous AC rating. Motors and compressors also pull a surge when they start, so check surge too. BLUETTI quotes 3,600W surge on the Premium 100 V2, the AC200P L and the FridgePower.

Heating loads are a special case. BLUETTI's "power lifting" mode runs resistive loads above the normal rating: up to 2,700W on the Premium 100 V2, 3,900W on the Premium 200 V2 and 2,250W on the Pioneer Na. Those loads include kettles, hair dryers and space heaters. BLUETTI limits power lifting to pure resistive loads.

A rooftop air conditioner is where most portable setups stop. Our answer on whether an Apex 300 can run a rooftop AC works through the hours. For the fixed RV5 system, BLUETTI recommends two B4810 batteries to run a 15,000 BTU AC overnight, and says a single B4810 limits the system to 4,320W.

Step 5: Add solar to refill it

To refill each day's use, divide daily Wh by (4 to 5 peak sun hours × 0.75). For the 790 Wh example, that comes to about 210–265W of panel. Here is the solar needed to refill each station from a full day's use:

Station Usable Wh Panel to refill in one day Solar input limit (BLUETTI)
Pioneer Na 765 about 205–255W 500W
Premium 100 V2 870 about 230–290W 1,000W
Premium 200 V2 1,763 about 470–590W 1,000W
AC200P L 1,958 about 520–655W 1,200W
Apex 300 2,350 about 625–785W 2,400W (more with a SolarX 4K)
Elite 320 2,720 about 725–905W 1,000W (our listing)

Which panels fit which input, and how many you can wire in series, is covered in BLUETTI solar input limits by model. If you are sizing a full system, our RV solar and battery calculator does the arithmetic.

Rules of thumb by rig

  • Weekend trips, fridge plus devices: about 1kWh covers roughly a day on our example loads. That means a Premium 100 V2, or a Pioneer Na if the trailer sits in freezing weather. BLUETTI says the Pioneer Na charges down to 5°F and discharges down to -13°F.
  • Several days dry camping, or a microwave and coffee maker: a 2–3kWh station, such as the Premium 200 V2, AC200P L or Elite 320, with a folding panel.
  • Long stays, or plans to grow: the Apex 300. It is the only station we carry that takes B300K or B500K expansion batteries. See which battery fits which BLUETTI.
  • Full-time, or air conditioning off batteries: a fixed 48V RV5 system. Compare it with a component build in RV5 vs a Victron build.

FAQ

Is a bigger station always better?

No. Weight goes up with capacity. BLUETTI lists the Premium 100 V2 at 25.3 lb, the Pioneer Na at 35.3 lb, the Premium 200 V2 at 53.35 lb, the AC200P L at about 63.5 lb and the Apex 300 at 83.78 lb. Our Elite 320 listing gives 74.96 lb, on wheels. If you lift it in and out every trip, buy for the capacity you actually use.

Why 0.85 and not the full rating?

BLUETTI's own runtime formulas apply both depth of discharge and inverter efficiency. Running loads straight from the 12V DC outlet skips the inverter, so you may do a little better than 0.85.

Can a BLUETTI run my RV through the shore cord?

Sometimes. See which power station can run a 30 amp RV and our guide to BLUETTI backup and UPS use in an RV.

Can I add capacity later?

Only on the Apex 300 (B300K/B500K), the FridgePower (up to three BlueCell 200) and the RV5 (B4810). BLUETTI lists no expansion battery for the Premium 100 V2, Premium 200 V2 or Pioneer Na. Found it cheaper? We'll beat it.
