SunGold Power 12KW 48V All-in-one Hybrid Solar Inverter | Whole Home Backup (200A)

SunGold Power 12KW 48V All-in-One Hybrid Solar Inverter Delivers Whole-Home Backup Power for True Energy Independence

Power outages are more than an inconvenience they're a wake-up call. Whether it's a storm knocking out the grid for days, rising utility rates eating into your budget, or simply the desire to stop depending on an infrastructure you can't control, the answer is the same: you need a smarter, more capable energy system. The SunGold Power 12KW 48V All-in-One Hybrid Solar Inverter (SGS-12K18MAX) is that system a single, integrated unit that combines solar input, battery storage, and grid or generator power into one compact, intelligently managed package.

This isn't a starter inverter for a shed or a camper van. This is a serious, whole-home-grade hybrid inverter designed for homeowners, farms, small businesses, and off-grid properties with high energy demands. It handles the heavy hitters HVAC systems, refrigerators, water pumps, power tools, and sensitive electronics without breaking a sweat. And because it's built on an all-in-one platform with a built-in MPPT solar charge controller, battery charger, and transfer switch, you get everything you need in one elegant package instead of a tangle of separate components and mismatched wiring. If you've been comparing your options and wondering whether a 12kW hybrid inverter is the right investment, the honest answer is this: if you want real whole-home backup and serious solar performance, it's hard to argue with a system that covers every base this thoroughly.

At Outbound Power, we specialize in portable and backup power solutions for homeowners, RVers, off-grid adventurers, and mobile businesses and we've seen firsthand what a difference the right inverter makes. The SunGold Power 12KW 48V All-in-One Hybrid Solar Inverter is one of the most capable, well-certified, and comprehensively featured systems available at its price point, and it's the kind of long-term investment that pays for itself in energy savings, reliability, and peace of mind for years to come.

 

SunGold Power 12KW 48V Features

One Unit Does the Job of Three Separate Devices

This inverter combines a solar charge controller, battery charger, and transfer switch into one box. No extra wiring, no mismatched parts just a clean, simple setup that saves you time, money, and a lot of headaches.

Your Whole Home Stays On When the Grid Goes Down

With a 200A pass-through, every circuit in your home keeps running during a power outage not just a few. Lights, fridge, AC, and appliances all stay powered without you lifting a finger.

It Pulls in More Solar Power Than Most Systems Can Handle

Each unit accepts up to 18kW of solar input through dual MPPT controllers. That means faster battery charging, more energy harvested daily, and fewer cloudy days that actually hurt your production numbers.

Clean Power Protects Every Device Plugged Into Your Home

The pure sine wave output delivers stable, grid-quality electricity. Sensitive electronics, medical equipment, and inverter-driven appliances all run safely without risk of damage from dirty or unstable power waves.

Add More Units Later as Your Energy Needs Grow

Stack up to six units in parallel for a combined 72kW of power. Whether you're expanding a home, running a farm, or scaling a business, your system grows with you — no starting over.

Works Outside Without Worry Thanks to Weatherproof Design

The IP65 rating means rain, dust, and humidity won't damage the unit. Install it indoors or outdoors, in a garage, shed, or mounted on an exterior wall it handles real-world conditions.

Check Your Energy System From Anywhere Using Your Phone

Built-in Wi-Fi and GPRS let you monitor solar production, battery levels, and system status remotely. No need to check the unit in person everything you need is right on your screen.
