Clean Power for Camping, RV and Home
The YJ903 series replaces gasoline generators in camping, RV and home-backup applications. Choose from four configurations — 3kW or 5kW pure sine wave output paired with 3072Wh to 10240Wh of lithium battery storage. Zero emissions, near-silent operation and no fuel to store: clean AC power at 220V/50Hz wherever the grid is unavailable.
Every YJ903 unit is an all-in-one power station. The built-in MPPT solar controller accepts up to 450V input from 550W monocrystalline panels, the AC charger delivers up to 20A, and the pure sine wave inverter outputs a rated 3000W or 5000W. A UPS transfer time of under 5ms keeps connected devices running seamlessly during outages, while overload protection and an 80°C temperature cutoff safeguard the system under heavy load. System voltages of 25.6V and 51.2V cover both compact and high-capacity battery banks.
Built for global partners: the YJ903 series ships with solar panel kits (550W × 3 to 9 panels depending on configuration) and 30m of 8.3mm² cable, sized for installation areas from 8 to 24 square metres. Ruihan supports OEM/ODM customization — logo, color, socket standards, packaging and firmware — under strict quality control, with certification documents available for customs and tenders. Send us your target market and MOQ for a tailored proposal within one business day.

Frequently Asked Questions
How long does it take to charge?
The built-in charger delivers up to 20A. Charging time depends on battery capacity and the input source — AC or solar.
Can it run an RV air conditioner?
Yes. The 3000W model powers typical RV AC units; the 5000W model covers larger units with headroom. Check your AC unit’s startup wattage against the rated output.
What can a 3072Wh – 10240Wh battery power?
A refrigerator overnight, a microwave for short cooking sessions, TV and router for a full evening, or power tools for a full workday. Runtime scales with battery size and connected load.
Can I recharge it with solar panels?
Yes. The integrated MPPT controller accepts up to 450V. Each configuration ships with 550W monocrystalline panels (3, 6, 6 or 9 pcs) sized to its installation area (8 to 24 m²).
What happens during a power outage?
The UPS function switches to battery power within 5ms — connected devices don’t notice the interruption.
Do you support OEM/ODM?
Yes. Logo, color, packaging, socket standard and firmware customization are available. Contact us with your target market and MOQ for a tailored quote.
