How Much Can You Run at the Same Time?
The 10kW inverter rating determines how much equipment the system can power simultaneously.
For example, a household could potentially operate a combination such as:
| Appliance |
Example Running Load |
| Refrigerator |
150W |
| Freezer |
150W |
| LED Lighting |
200W |
| TV + Electronics |
200W |
| Wi-Fi + Computers |
250W |
| Microwave |
1,200W |
| Washing Machine |
500W |
| Well Pump |
1,000W |
| Mini-Split A/C |
1,500W |
| Example Combined Load |
Approx. 5,150W |
That example remains well below the inverter's 10,000W output capacity. Actual appliance consumption and startup surge will vary by model.
20.48kWh Battery Bank, How Long Can It Run?
The system includes four 51.2V 100Ah LiFePO4 batteries, providing approximately 20.48kWh of nominal energy storage.
| Average Power Consumption |
Approx. Theoretical Runtime |
| 500W |
41 hours |
| 1,000W |
20.5 hours |
| 2,000W |
10.2 hours |
| 3,000W |
6.8 hours |
| 5,000W |
4.1 hours |
| 8,000W |
2.6 hours |
Runtime figures are simplified theoretical estimates based on nominal battery capacity. Actual runtime will be lower due to inverter losses, battery operating limits, temperature, state of charge, startup loads, and other system conditions.
During daylight hours, the solar array can also help power your loads while recharging the battery bank, which can significantly extend operating time.
5.4kW Solar Array
The system includes 12 × 450W bifacial N-Type monocrystalline solar panels for a total rated solar capacity of:
5,400 Watts of Solar
As a simple example, if the array receives approximately 5 peak sun hours in one day:
5.4kW × 5 hours = approximately 27kWh of theoretical solar production.
Actual solar production varies based on:
- Location
- Season
- Weather
- Panel orientation
- Installation angle
- Shading
- Temperature
- Electrical and system losses
Understanding the System: 10kW + 20.48kWh + 5.4kW Solar
⚡ 10kW Inverter Power
Determines approximately how much equipment you can power at the same time.
🔋 20.48kWh Battery Storage
Determines approximately how long your loads can operate when solar or another charging source is unavailable.
☀️ 5.4kW Solar Array
Determines how much solar power the system can potentially generate under available sunlight.
A properly sized off-grid system needs all three to match your application.

Not Sure Which Solar Kit You Need?
Choosing an off-grid solar system based only on the size of your home can lead to an undersized or unnecessarily expensive system.
The best system depends on what you need to power, how much power those appliances use, and how long you need to run them.
Before ordering, contact us with:
- The appliances and equipment you want to power
- The wattage or model numbers of your largest loads
- How many hours per day you expect to use them
- Whether you need 120V, 240V, or both
- Your installation ZIP code
Our team can help determine whether the 10kW / 20.48kWh system is the best fit or whether a different configuration would better match your project.
Frequently Asked Questions
Can this system power an entire house?
Potentially, depending on your home's electrical loads and daily energy consumption. The inverter provides up to 10kW of output, but homes with multiple large electric appliances or HVAC systems may require additional inverter, battery, or solar capacity.
Can it run a refrigerator and freezer?
Yes. Refrigerators and freezers are generally modest loads compared with the overall capacity of the system, although startup surge should still be considered.
Can it run a well pump?
Many well pumps may be supported. The pump's voltage, running wattage, and startup surge should be checked before confirming compatibility.
Can it run an air conditioner?
It can support many appropriately sized air-conditioning systems, including certain mini-splits and window units. Large central A/C systems should be evaluated individually because compressor startup requirements can be substantial.
Can it power 240V appliances?
Yes. The included inverter provides 120V/240V split-phase AC output. Individual appliance requirements should still be verified.
How much battery storage is included?
The four included 51.2V 100Ah batteries provide approximately 20.48kWh of nominal energy storage.
How many solar panels are included?
The kit includes 12 × 450W solar panels, providing a total rated solar array of 5,400 watts.
Can I expand the system later?
The compatible inverter platform supports parallel expansion. Any expansion should be designed and installed according to SunGoldPower's requirements and applicable electrical codes.
How do I know if 20.48kWh is enough for me?
The best way is to calculate your expected daily energy consumption in kilowatt-hours (kWh). Send us the appliances you want to power and your expected daily usage, and we can help you determine the appropriate system size.
Important: Solar system performance and runtime vary based on loads, installation, solar conditions, temperature, battery state of charge, system losses, and other factors. High-power appliances and motor loads should be verified before purchase. Professional installation by a qualified electrician or solar installer is recommended.
