SunGold Power 12KW All in One Off Grid Solar Inverter FR12K-B with 72KW Scalable Power so That Your Home, RV, or Business Never Goes Dark Again
When the grid fails or when you’ve chosen to leave it behind entirely the last thing you want is a patchwork of mismatched components held together by hope and zip ties. The SunGold Power 12KW All in One Off Grid Solar Inverter FR12K-B gives you a single, intelligently engineered power hub that handles solar charging, battery management, AC output, and generator integration in one clean, high-performance package. Whether you’re protecting your household from outages, powering a remote cabin, keeping your RV fully stocked with creature comforts, or running a mobile worksite, this inverter is purpose-built to deliver serious, dependable energy independence.
Most budget all-in-one inverters give you one MPPT, limited expansion, and no load separation capability. The FR12K-B goes further dual MPPTs, 6-unit scalability, a versatile generator/load port, and built-in RSD all in a single unit that’s engineered for serious off-grid use. You’re not buying the bare minimum and hoping it grows with you. You’re buying a platform designed from the start to handle whatever comes next.
At Outbound Power, we don’t just list products we back them. We’ve spent years helping homeowners, full-time RVers, off-grid builders, and mobile professionals find the right power solutions for their specific situations, and we know the difference between equipment that looks good on a spec sheet and equipment that holds up when it actually matters.
SunGold Power 12KW All in One Off Grid Solar Inverter Features
This Inverter Delivers a Massive 12,000 Watts of Clean Power
It puts out 12,000W of pure sine wave power safe for all your appliances, tools, and electronics. Run your fridge, AC, and power tools at the same time without any issues or equipment damage.
Connect Up to Six Units and Get 72,000 Watts Total
Need more power later? Simply add more units. Up to six FR12K-B inverters can work together, giving you up to 72,000W total. It grows with your needs so you never have to start over.
Two MPPT Controllers Harvest Up to 13,200 Watts From the Sun
Dual 22A MPPT inputs pull in as much solar energy as possible even on cloudy days. With two separate inputs, you can run panels in different directions and still charge your batteries fast and efficiently.
Works With Both 120V and 240V So Any Home Can Use It
Whether your home runs on single-phase 120V or split-phase 120V/240V, this inverter handles both. That makes it a perfect fit for most American homes, small businesses, RVs, and mobile work setups.
The Generator Port Also Works as a Second Power Output
The built-in generator port does double duty use it for a generator or flip it to a second load output. This lets you easily separate critical loads from non-essential ones without extra hardware or wiring.
Solar-Only or Hybrid Charging Gives You Full Energy Control
Choose how your batteries charge solar only, or solar combined with a generator or grid source. This flexibility lets you manage energy costs, extend battery life, and always have a reliable backup charging option ready.
Built-In Rapid Shutdown Keeps Your System Safe and Code-Compliant
The FR12K-B has PV Rapid Shutdown built right in no extra device needed. It meets NEC safety requirements for rooftop solar and lets first responders quickly cut power in an emergency, protecting your home and family.
