Bluetti RVSolar 48V Power System Guide for Campervans & RVs (RV5 + B4810 Specs & FAQs)
Bluetti RVSolar 48V Power System for Campervans & RVs
Discover how the Bluetti RVSolar 48V Power System — featuring the RV5 Power Hub and B4810 LiFePO₄ battery — redefines off-grid power for campervans, RVs, and overland rigs. This in-depth guide covers real-world use, key specs, setup considerations, and the most common FAQs.
5,000W AC Output 48V Core System 5.12 kWh LiFePO₄ BatteryOverview
The Bluetti RVSolar 48V Power System is a modular, all-in-one energy solution built around the RV5 Power Hub and B4810 LiFePO₄ Battery. It’s designed to power everything in your campervan or RV — from rooftop air conditioners to induction cooktops — with less wiring, higher efficiency, and true off-grid autonomy.
Core Components
- RV5 Power Hub: 5,000W inverter/charger with integrated MPPT and alternator input.
- B4810 Battery: 51.2V 100 Ah LiFePO₄ (5.12 kWh usable).
- Smart Distribution Panel: AC & DC circuit management.
- 10.1″ Touchscreen Monitor: System control & diagnostics.
- PV Input: Up to 1,800W (12–50V, 50A)
Why 48V Matters
Traditional 12V systems are limited by high current and voltage drop when running powerful devices. The Bluetti RVSolar system uses a 48V backbone, allowing smaller cabling, reduced heat, and higher efficiency, perfect for high-draw appliances like air conditioners.
- Less current = smaller wire gauge and less loss
- Improved inverter efficiency under load
- Better compatibility with 48V air conditioners
- Still supports 12V & 24V outputs through its distribution panel
Charging Options
- Shore Power: Up to 5,000W AC charging.
- Solar Input: Up to 1,800W (12–50V, 50A)
- Vehicle Alternator: 600W (12V) or 1,200W (24V) DC-DC charging.
- Generator Backup: Compatible via standard shore connection.

Frequently Asked Questions
Can the Bluetti RVSolar system run a rooftop A/C unit?
Yes. With 5,000W of continuous output, the system can power a 48V or most 120V A/C units, plus additional loads like fridges or fans simultaneously. For best performance, use a 48V-native A/C unit directly and properly connected to the battery bank.
How long does one B4810 battery last?
For each 5.12 kWh battery, light users can expect several days of runtime; heavier users with A/C or induction cooking may prefer 2–4 batteries for extended off-grid time.
Can I charge while driving?
Yes. The built-in DC-DC function charges at up to 600W from 12V alternators or 1,200W from 24V systems. Combined with solar, you can replenish the system efficiently on travel days.
Is it safe in cold or wet conditions?
The B4810 is IP65-rated and self-heating, allowing safe operation in colder climates. The RV5 and distribution components should still be installed in a dry, ventilated enclosure.
How does it compare to a Victron system?
Bluetti’s RVSolar is a pre-engineered, plug-and-play system ideal for builders wanting speed and simplicity. Victron offers more flexibility but requires more design work and individual components. Both are excellent depending on your goals.
