PRODUCT DESCRIPTION
Powerful Home Backup. Off-Grid Freedom. Energy When You Need It Most.
Stay prepared for outages and take greater control of your energy with this powerful 7,200W whole-home solar generator and battery backup system.
Combining a 7,200W pure sine wave inverter, 4,800Wh (4.8kWh) battery, 120/240V output, and ultra-fast 10ms UPS functionality, this expandable power system is built to provide dependable electricity for everything from everyday electronics to compatible high-demand household appliances.
Whether you're preparing for unexpected blackouts, building an off-grid solar power system, or looking for a reliable home battery backup, you get serious power without sacrificing flexibility.
⚡ 7,200W of Powerful 120/240V Home Backup
Get up to 7,200W of pure sine wave AC output with 120/240V capability, providing the power needed to operate a wide range of compatible household equipment.
Power essentials such as refrigerators, freezers, lights, Wi-Fi, TVs, computers, microwaves, and more—or support compatible higher-demand 240V equipment when properly configured.
Unlike smaller portable power stations designed primarily for electronics, this system is built for serious home backup and off-grid power applications.
What Can a 4.8kWh Battery Power?
Here's what the 4,800Wh battery could approximately provide when powering individual devices:
| Appliance / Device | Typical Example Wattage | Approx. Runtime* |
|---|---|---|
| Wi-Fi Router | 10W | ~408 hours |
| LED Light | 10W | ~408 hours |
| Laptop | 60W | ~68 hours |
| 55" LED TV | 100W | ~41 hours |
| Refrigerator | 150W while running | ~27 hours of compressor runtime |
| Chest Freezer | 100W while running | ~41 hours of compressor runtime |
| CPAP Machine | 40W | ~102 hours |
| Box Fan | 75W | ~54 hours |
| Microwave | 1,200W | ~3.4 hours of continuous use |
| Coffee Maker | 1,000W | ~4.1 hours of continuous use |
| Space Heater | 1,500W | ~2.7 hours |
| Window A/C | 1,000W | ~4.1 hours |
Estimates assume approximately 85% usable energy after conversion losses, or about 4.08kWh. Actual consumption and runtime vary by appliance, startup/surge requirements, battery state, temperature, operating conditions, and system efficiency. Appliances such as refrigerators cycle on and off, so actual elapsed runtime can differ substantially from continuous-wattage calculations.
See the Difference: Estimated Energy Consumption
A 4.8kWh battery gives you the flexibility to prioritize essential loads during an outage rather than powering everything continuously. Low-consumption essentials can operate dramatically longer than electric heating, cooling, and other high-wattage equipment.
• Seamless 10ms UPS Backup
When grid power unexpectedly goes down, you don't want critical electronics going down with it.
Built-in 10ms UPS functionality provides an extremely fast transition to battery power for compatible connected equipment, helping keep essential electronics running with minimal interruption.
Ideal for supporting equipment such as Wi-Fi routers, computers, security equipment, entertainment systems, and other compatible electronics during unexpected outages.
• Simple Plug-and-Play Setup
Powerful backup doesn't have to mean complicated operation.
The convenient plug-and-play design helps simplify setup, allowing you to start using your power system with minimal hassle.
For home-circuit integration, appropriate electrical equipment and professional installation may still be required.
• Expand Your System Up to 21,600W
Need more power in the future?
Your system can grow with you.
Combine up to three compatible Powerhouse units to reach an impressive:
21,600W of Total Output
Expand further with compatible battery power pods, solar panels, wind turbines, and other system components to increase energy storage, renewable generation, and overall capability.
Start with what you need today and build toward a larger whole-home energy storage system tomorrow.
☀️ Recharge With Up to 2,000W of Solar
Turn sunlight into stored energy.
Connect up to 2,000W of compatible solar panels to recharge your battery using renewable energy—ideal for homeowners looking to reduce grid dependence or create an off-grid power solution.
Solar charging capability makes this system especially valuable for:
Home backup • Off-grid properties • Cabins • Workshops • Emergency preparedness • Renewable energy storage
• Up to 1,000W of Wind Charging
Solar isn't your only renewable option.
The system supports up to 1,000W of compatible wind generation, giving you another potential source of renewable energy when conditions allow.
Combining solar, wind, and traditional AC charging provides greater flexibility than relying on a single charging method.
• Multiple Ways to Recharge
Keep your battery ready using:
☀️ Solar Power — Up to 2,000W
💨 Wind Power — Up to 1,000W
⚡ AC/Grid Power
Whether you're connected to the grid or building toward greater energy independence, you have multiple options for replenishing stored energy.
• Seamless Home Integration
Connect the system with a compatible transfer switch or power inlet box to create a more convenient home backup solution.
When properly installed, this allows stored battery power to support selected household circuits without relying solely on extension cords throughout your home.
Electrical integration should always follow manufacturer specifications, local electrical codes, and applicable installation requirements.
• Monitor Your Power in Real Time
Stay informed and make every watt count.
The built-in LED display provides real-time information including:
Battery Level – See how much stored energy remains.
Power Usage – Monitor how much electricity connected equipment is consuming.
Wattage – Understand your current system load.
Estimated Runtime – See approximately how much operating time remains.
During an outage, this information can help you decide which appliances to prioritize and when to conserve battery power.
One System. Serious Backup Power.
This isn't just another portable power station.
It's an expandable 120/240V home battery backup system designed for homeowners who want serious power, renewable charging options, and the flexibility to expand as their energy needs grow.
