7,200W Whole-Home Backup Power System – 4,800Wh Battery | 120V/240V Expandable Solar Generator

Powerful, Reliable Energy When You Need It Most

Keep your home powered through outages, emergencies, and off-grid adventures with a 7,200W Whole-Home Backup Power System engineered for serious energy independence.

Delivering up to 7,200 watts of 120V/240V pure sine wave AC output and backed by a 4,800Wh battery, this high-capacity power station can handle everything from refrigerators, lights, TVs, and internet equipment to demanding appliances such as air conditioners, well pumps, microwaves, and select electric appliances.

And when your energy needs grow, your system can grow with you. Connect up to three compatible Powerhouses for up to 21,600W of combined output, while adding compatible battery Power Pods, solar panels, wind generation, and other expansion equipment for greater capacity and runtime.

Whether you're preparing for the next power outage, building an off-grid property, or looking for an alternative source of home backup electricity, this system puts dependable power within reach.


⚡ What Can 7,200W Power at the Same Time?

Here's an example of a realistic group of household loads that could potentially operate simultaneously while remaining below the system's 7,200W continuous output limit.

Appliance / Device Example Running Wattage*
Refrigerator 150W
Chest Freezer 150W
Wi-Fi Router + Modem 25W
10 LED Lights 100W
65" LED TV 150W
Laptop + Phone Chargers 100W
Microwave 1,200W
Coffee Maker 1,000W
Sump Pump 800W
Window A/C Unit 1,200W
Additional Household Load 1,000W
Estimated Total 5,875W
System Output Capacity 7,200W
Remaining Running-Watt Capacity ≈1,325W

One Powerhouse. Multiple Essentials. One Powerful Backup Solution.

With 7,200W of available output, you don't have to choose between keeping the refrigerator cold and keeping the lights on. Depending on appliance requirements, you can operate numerous essential household devices simultaneously.

Important: Appliance wattage varies significantly by model, and motors, compressors, pumps, and HVAC equipment can require substantially more power during startup. Always verify the running and starting/surge wattage of your specific appliances before connecting multiple loads.


Built for Whole-Home Backup & Off-Grid Power

🔋 4,800Wh of Stored Energy

The integrated 4,800Wh battery capacity provides substantial stored energy for outages, emergencies, cabins, workshops, RV applications, and off-grid living.

Unlike output wattage, which determines how much equipment you can operate at once, the 4,800Wh battery capacity helps determine how long those devices can operate before the battery needs to be recharged.

For example:

Average Continuous Load Approx. Theoretical Runtime*
100W 48 hours
250W 19.2 hours
500W 9.6 hours
1,000W 4.8 hours
2,000W 2.4 hours
4,000W 1.2 hours

These are simple capacity ÷ load estimates. Actual usable runtime will be lower and varies based on inverter losses, temperature, battery condition, appliance cycling, startup loads, and other operating conditions.


⚡ Serious 7,200W 120V/240V Power

Get up to 7,200W of pure sine wave inverter output with both 120V and 240V capability.

Pure sine wave power provides clean AC electricity suitable for a wide variety of household electronics and appliances, giving you the versatility needed for both everyday backup and demanding applications.

From charging your phone to powering major appliances, this isn't just a portable charger—it's a serious home backup power solution.


🏠 Seamless Home Backup Integration

Take your backup power beyond extension cords.

The system can be integrated with a compatible transfer switch or power inlet box, allowing properly selected home circuits to receive backup power from your system.

This can make it easier to keep important circuits operating during a grid outage without running extension cords throughout your home.

Professional installation by a qualified electrician may be required for transfer switches, inlet boxes, 240V circuits, and other home electrical connections. Never backfeed a home's electrical system through a standard wall outlet.


☀️ Recharge With Up to 2,000W of Solar

Turn sunlight into backup electricity.

With support for up to 2,000W of compatible solar input, you can build a renewable charging system capable of replenishing stored energy during extended outages or off-grid use.

That means your backup system doesn't necessarily stop working once the initial battery charge is depleted—you can generate additional energy whenever adequate sunlight is available.


🌬️ Add Up to 1,000W of Wind Power

Want another renewable energy source?

The system also supports up to 1,000W of compatible wind input, giving off-grid users additional flexibility when solar conditions aren't ideal.

Combine compatible renewable charging options to create a more versatile energy system for cabins, remote properties, workshops, emergency preparedness, and off-grid living.


🔌 Multiple Ways to Recharge

Choose the charging source that fits your situation:

Solar Power — Up to 2,000W of compatible solar input

Wind Power — Up to 1,000W of compatible wind input

AC Power — Recharge from conventional grid electricity when available

This hybrid charging flexibility helps you stay prepared whether you're at home, off-grid, or dealing with an extended outage.


Start With 7,200W. Expand Up to 21,600W.

Your power requirements may change—and your backup system can change with them.

Start with one 7,200W Powerhouse and expand your system with additional compatible units.

Configuration Maximum Combined Output
1 Powerhouse Up to 7,200W
2 Powerhouses Up to 14,400W
3 Powerhouses Up to 21,600W

You can also expand the system with compatible:

  • Battery Power Pods

  • Solar Panels

  • Wind Turbine Equipment

  • Additional Powerhouses

  • Home Backup Accessories

This gives you the flexibility to start with the capacity you need today and build toward a larger whole-home or off-grid energy system over time.


⚡ 10ms UPS Functionality

When the grid goes down, every second matters.

With 10ms UPS functionality, compatible connected equipment can transition to battery power extremely quickly when utility electricity is interrupted.

This makes the system especially useful for equipment you don't want suddenly losing power during an outage.


🔌 Plug-and-Play Convenience

Powerful doesn't have to mean complicated.

The system is designed with plug-and-play operation in mind, allowing you to get started with minimal setup for supported standalone applications.

Simply charge your system, connect compatible devices, and begin using stored power.

For permanent home electrical integration, transfer switches, or other hardwired applications, use a qualified electrician and follow all applicable electrical codes.


📊 Know Exactly Where Your Power Stands

The built-in LED display provides important system information at a glance, including:

  • Current battery level

  • Real-time power usage

  • Wattage information

  • Estimated remaining runtime

Instead of wondering how much energy you have left, you can monitor your system and make informed decisions about which appliances to operate.


Be Ready Before the Next Outage

Power outages don't make appointments.

Whether caused by severe weather, grid problems, emergencies, or unexpected utility interruptions, losing electricity can quickly disrupt everything from refrigeration and communication to heating, cooling, lighting, and essential household equipment.

With 7,200W of output, 4,800Wh of battery storage, 120V/240V capability, renewable charging, and expandable whole-home power, you can build a backup energy system designed around your needs.
