BLUETTI 5kWh RVSolar 48V Power System + VELIT 2000R 48V A/C + VELIT Air Heater + Dometic CRX 80U + Vent Fan

BLUETTI 5kWh 48V Power System + VELIT 2000R 48V A/C + VELIT Air Heater + Dometic CRX 80U + MaxxAir Vent Fan

OVERVIEW
A complete off-grid bundle for campervans and small RVs. This package pairs high-efficiency 48V battery power with a variable-speed rooftop air conditioner, an efficient air heater for cold nights, and a vent fan for continuous airflow. Built for professional upfitters and DIY installs alike. 

The 48V core system delivers 120V AC, and 12V or 24V DC via the integrated AC/DC distribution panel. However, while the DC side distributes 12V or 24V power for your lights, fans, and other appliances, the battery bank itself operates at 48V.

Thus, 48V air conditioners can be wired directly to the 48V battery bank, bypassing the distribution panel. This setup minimizes current, reduces losses, and allows the air conditioner to run more efficiently and reliably, especially in hot weather or extended off-grid use. This setup bypasses the RV5 Power Hub and delivers power straight from the battery bank, ideal for high-demand loads that benefit from maximum efficiency and minimal conversion loss. Because the Epad receives data directly from the battery BMS, it continues to show:

• Correct state of charge

• Correct runtime remaining
  

Even with the A/C pulling power directly from the battery bank, SOC and remaining runtime tracking operates as usual, however the real-time watt draw readout for the A/C does not appear on the Epad screen. 

WHAT’S INCLUDED

• BLUETTI 5kWh 48V (51.2V nominal) LiFePO4 Power System

• VELIT 2000R 48V Rooftop Air Conditioner (install kit included)

• VELIT Air Heater (install kit included)

• MaxxFan Deluxe

• Dometic CRX 80U AC/DC Fridge/Freezer

WHO THIS IS FOR

• Van builders and DIYers who want a matched 48V solution for cooling, heating, and ventilation

• Customers prioritizing efficient A/C performance, reduced wiring losses, and clean integration

• Installers who want proven components that work well together

KEY BENEFITS

• 48V efficiency: lower current and smaller cables vs. 12V systems

• Variable-speed A/C: sips energy at partial load; ramps when needed

• Complete climate control: cool, heat, and ventilate with one bundle

• Standard 14"x14" roof opening: simpler layout and retrofits

• Scalable energy: start at 5kWh and expand as your needs grow

• Supported by our team: guidance for parts selection and install approach

TECHNICAL HIGHLIGHTS (SUMMARY)

• System voltage: 48V (51.2V LiFePO4)

• Base capacity: 5kWh (expandable with add-on batteries)

• A/C: VELIT 2000R 48V, inverter/variable-speed, 14"x14" opening, low-profile rooftop unit

• Heater: VELIT air heater (diesel or gasoline)

• Vent: MaxxAir roof vent fan, intake/exhaust modes

EXPECTED RUNTIME GUIDANCE (GENERAL)

• For extended A/C runtime or hotter climates, plan on 10–15kWh total capacity.

• Ventilation (MaxxAir) and strategic shading reduce A/C duty cycle and improve comfort.

• Heating demands vary widely by climate and insulation; the air heater is efficient but fuel supply and ducting layout affect performance.

FAQ

Q: Can I run the A/C on just the 5kWh base?
A: For shorter cooling periods and with good insulation, absolutely! For longer runtime or hot/humid climates, plan 10–15kWh.

Q: Is this bundle DIY-friendly?
A: Yes for experienced DIYers. Professional installers will complete faster and reduce callbacks.

Q: Will this fit my vehicle?
A: Most vans and small RVs that accept a 14"x14" roof opening. Verify thickness, bracing, and interior panel clearance.

Q: Can I expand later?
A: Yes. The battery system is designed to scale. Add capacity as your needs grow.
