Product Description

The RICH SOLAR NOVA 3K12 is a 3000W 12V pure sine wave inverter with a built-in transfer switch, designed for RVs, campers, trailers, and vans. It delivers clean 120VAC power with pure sine wave output, making it suitable for sensitive electronics and compatible off-grid power applications.

With a 6000W peak power rating, smart LCD display, automatic transfer switching, and advanced protection features, this inverter is built to support reliable power conversion from 12V battery systems.

Key Features

  • Pure Sine Wave Output (<5% THD): Delivers clean, stable power for sensitive electronics, including medical equipment and servers.
  • 91% High Efficiency: Maximizes battery life with minimal energy loss and low standby consumption.
  • Seamless Automatic Transfer Switch: <20ms transfer time for uninterrupted power during outages; Dual transfer modes: Normal (fridges, tools) / Fast (computers, servers).
  • Advanced Protection System: Adjustable low voltage shutdown (10.5V-12.8V) with overload/short-circuit/overheat protection.
  • Marine-Grade Durability: Optional drip shield and temperature-regulated cooling fan for harsh environments.
  • Smart LCD Display: Shows real-time voltage, load, and system status.
  • Safety Certified: Complies with UL standards, compatible with 12V deep-cycle and lithium (BMS) batteries.
