A solar generator with a high-frequency inverter and a panel configuration producing 300V–400V DC can be an efficient system for handling higher power outputs, such as 4500 watts. 

Here’s a detailed breakdown of how the system works, including how much actual energy you can expect from the panels and from this Product

The Goodness of this Product:

• It's Pure Sinewave Inverter
• Unique Product for Direct Solar utilization without the need of Battery backup.

Something We think need Attention from the Manufacturer:

• The Warranty is only for 1 year. : As most string inverter are for 5 years Warranty as well as the Hybrid Inverters come with 2 years of warranty 
• Need Time-tested reviews until Full trust on the Product comes.

1. Overview of Solar Generators with High-Frequency Inverters

• High-frequency inverters operate by converting DC to AC power through a process that uses high switching frequencies, making them more compact, efficient, and lightweight compared to traditional inverters.

• Panels in Series Configuration: When you connect solar panels in series, their voltages add up, but the current remains the same. For example, if each panel produces around 40V DC and they are connected in series, a 10-panel array would generate around 400V DC.

• Power Rating (4500 watts): This refers to the maximum amount of power the system can handle. It’s essential to choose an inverter with a high enough rating to match your solar array output.

2. How Much Energy the Panels Produce

The actual energy produced by solar panels depends on several factors:

a. Solar Panel Efficiency

• Efficiency rating: The efficiency of a panel dictates how much sunlight is converted into usable electricity. For example, a panel with 20% efficiency will convert 20% of the sunlight it receives into electricity.

• Example panel: A typical high-efficiency solar panel might produce around 300-400 watts of power under ideal sunlight conditions (1,000 W/m² of solar irradiance).

b. Solar Irradiance

• Solar panels are typically rated for their output under Standard Test Conditions (STC), which assume direct sunlight of 1000 watts per square meter (W/m²) at 25°C.
• The actual energy you get from the system depends on the local irradiance levels (measured in kilowatt-hours per square meter per day, or kWh/m²/day).

c. System Efficiency Losses

• Inverter losses: While high-frequency inverters are efficient, they typically have about 95%-98% efficiency. This means a small portion of the energy is lost during the DC to AC conversion.

• Temperature losses: As solar panel temperatures rise above 25°C, their efficiency decreases. For example, every 1°C rise can reduce panel efficiency by about 0.3%-0.5%.

• Other losses: Energy losses due to wiring, shading, and soiling (dust or debris on the panels) can account for another 5%-10% reduction.

3. Calculating the Actual Energy Output

Let’s assume you have a solar array producing 4500 watts at 1000 W/m² irradiance. Here’s how to calculate the actual energy output based on common factors.

Daily Energy Production

Energy output is typically calculated in kilowatt-hours (kWh). The formula for energy output is:

$$\text{Energy (kWh)} = \text{Power (kW)} \times \text{Sun Hours}$$

• Power of the array: 4500 watts = 4.5 kW.
• Sun hours: This is the number of peak sunlight hours per day. In sunny regions (e.g., California, India), you may get 5-6 hours/day of peak sunlight. In less sunny regions (e.g., northern Europe), you might only get 3-4 hours/day.

Assuming 5 sun hours/day:

$$4.5 \text{ kW} \times 5 \text{ hours/day} = 22.5 \text{ kWh/day}$$

This is the theoretical maximum energy the system could produce in one day under ideal conditions.

System Losses

• Inverter efficiency: Assuming 95% inverter efficiency, the actual energy output would be:

$$22.5 \text{ kWh/day} \times 0.95 = 21.375 \text{ kWh/day}$$

• Other losses (wiring, temperature, shading): Let’s assume an additional 10% loss:

$$21.375 \text{ kWh/day} \times 0.90 = 19.24 \text{ kWh/day}$$

So, in a typical scenario with 4500 watts of panel power, you might get around 19.2 kWh of usable energy per day.

4. Factors That Impact Actual Energy Output

• Location and climate: Areas with more sunlight and higher solar irradiance will generate more energy. For example, southern regions with strong sunlight might generate more than 5 hours/day, while northern regions may generate less.

• Panel Orientation: The angle and direction of the solar panels affect how much sunlight they receive. Optimal orientation depends on latitude.

• Seasonal Variations: The amount of sunlight available varies throughout the year, with winter months typically producing less energy due to shorter daylight hours.

5. Conclusion

• A solar generator with a high-frequency inverter, panels in series producing 300V–400V DC, and a maximum of 4500 watts can produce around 19-22 kWh/day under good conditions. 
• The actual energy output will vary depending on factors like panel efficiency, system losses, and location.
• While the rated capacity is 4500 watts, real-world production will typically be a bit lower after accounting for inverter losses, wiring inefficiencies, and environmental factors.

This system setup is ideal for mid-sized homes or off-grid systems needing reliable power with high efficiency.

Overall a Great Products, just the need of Time and use will decide the quality of  MAXMOL MPPG 4003 Solar generator.
