The RUiXU SUNON12 12kW Off-Grid Inverter Provides Serious Off-Grid Power, Built for Whole-Home Confidence

The RUiXU SUNON12 gives you the power, flexibility, and control to build a stronger off-grid or backup power system around your energy needs. With 12,000W of rated output, 120V/240V single/split-phase power, and up to 24,000W of solar input, this all-in-one inverter is designed to help run demanding home, cabin, shop, or small commercial loads with greater confidence.

Pair it with a compatible 48V battery system and take advantage of powerful hybrid charging from solar, grid, or generator input. The SUNON12 supports up to 250A of solar charging and up to 160A from grid or generator, giving your system more ways to stay charged when conditions change.

Dual MPPT technology helps maximize solar harvest from your array, while intelligent time-sharing charge and discharge settings allow you to better control when energy is stored and when it is used. For larger systems, the SUNON12 can be stacked in parallel with up to 6 units, expanding total output capacity up to 72kW.

Whether you are building an off-grid energy system, adding serious backup power, or designing a scalable solar storage setup, the RUiXU SUNON12 delivers the core power management features you need in one compact, high-capacity inverter.


RUiXU SUNON12 12kW Off-Grid Inverter Features

Two MPPT Inputs Work Together to Capture More Solar Power

Dual MPPT technology runs at 99% efficiency, independently optimizing panels on different roof angles or locations. You harvest more solar energy every day, which means faster battery charging and lower reliance on grid or generator power.

Charge From Solar and the Grid at the Same Time

The SUB hybrid charging mode pulls up to 250A from both solar and grid sources simultaneously. Even on cloudy days, your batteries stay full and your home keeps running without interruption or manual switching between sources.

Schedule Exactly When Your System Charges and Discharges

The time-sharing function lets you charge batteries during cheap off-peak hours and draw from them during expensive peak hours. This one feature can noticeably reduce your monthly electricity bill with zero extra effort after setup.

Stack Up to Six Units and Scale to 72kW

One SUNON12 starts at 12kW. Add up to five more units for a total of 72kW. This makes it easy to grow your system over time without replacing hardware or starting your installation over from scratch.

Smart Load Output Keeps Your Most Important Appliances Running

The 63A smart output automatically sheds non-critical loads when battery reserves get low. Refrigerators, medical equipment, and lighting stay on while pool pumps and workshop tools power down first, protecting what matters most.

Works With Almost Any Generator You Already Own

A dedicated generator input supports both 120V and 240V operation, covering nearly every portable or standby generator on the market. It is your reliable backup for long cloudy stretches, heavy loads, or unexpected high-demand situations.

Monitor Your Entire System From Your Phone, Anywhere

The included WiFi dongle connects to the RUiXU app for real-time visibility into battery levels, solar input, and load usage. Whether you are at work or across the country, you always know exactly what your system is doing.
