In a home solar system, many people are willing to use a 5000W inverter to power themselves so that a range of electronic devices in the home work. However, the question of what a 5000W inverter can run in the complex electrical system of a home is puzzling, and in this article, we are going to provide you with a comprehensive overview of a range of issues regarding 5000W inverters.

1. Parameters of a 5000W inverter

Size: For a 5000W inverter, its size ranges roughly from 450*200*120mm to 625*400*168mm. It may vary depending on the brand as well as the type of product, for example for the SYP 5K-S inverter the size is 446*350*133mm.

Weight: 5000W inverters are usually wall or rack mounted, which means that 5000W inverters are not very heavy, usually between 10kg and 15kg.

The number of inverters that can be paralleled; for the inverter parallel number should not be too much in order to prevent the solar system is not stable or have potential harmonic interference, in general, string grid-tied 5000W inverters can be paralleled, some off-grid and hybrid 5000W inverters can also be used in parallel. This may also vary with the brand of your inverter. During the paralleling process of 5000W inverters, you can use single-phase paralleling and also three-phase paralleling.

The carrying motor capacity: the carrying motor capacity of the inverter is to ensure that the motor can work normally under the power support of the inverter, in which the use of technology and characteristics of the inverter have an impact on the carrying motor capacity, the general carrying motor capacity of 5000W inverter is about 4HP, but this is also related to the actual design of the inverter, you can consult with the sales staff about the specific carrying motor capacity of the 5000W inverter. You can ask the salesman about the specific motor capacity of 5000W inverter.

Protection level: the protection level of the inverter is mainly related to the waterproof and dustproof ability of the equipment, some inverters have IP67 or higher protection level, they can be immersed in a certain degree of water and the inverter will not be damaged, such inverters will be more expensive, if you are installing the inverter indoors, you can choose IP20 inverters.

Ambient temperature: 5000W inverter because of different brands and applicable sites, resulting in 5000W inverter operating temperature ranging from -40 ℃ to 50 ℃, but the general household 5000W inverter operating temperature between -10 ℃ and 50 ℃.

Warranty time: For the warranty time of the inverter in the solar energy system, it is generally around 5 years. But for some brands of solar inverters, the warranty time may be about 2 years. The specific inverter warranty time is also related to the brand you choose.

Certification: Inverters need some certifications before entering the market to be able to sell normally, these certifications are a kind of guarantee for the quality and safety of the inverters, usually there are CE certificates, UL certificates, FCC certificates and so on.

Types of batteries that can be connected: Generally, in solar energy system, 5000W inverter can be connected with lithium iron phosphate batteries, lead-acid batteries and other kinds of batteries, you can choose the right type of batteries for you according to your actual needs and your budget cost, so that your solar energy system will have a good effect of energy storage.

Rated Battery Voltage: For 5000W inverter, the rated voltage of the battery to be connected must be 48V, 12V or 36V cannot be used. And the maximum current of the inverter to charge the battery is 100A.

2. What appliances can a 5000W inverter run?

A 5000W inverter is rated at 5000W, indicating the ability of a 5000W inverter to deliver a stable output under ideal conditions. However, in actual use the efficiency of 5000W is between 85% and 90%, so the power that can be achieved by a 5000W inverter in actual use is below 4500W. For a 5000W inverter, it is one of the more powerful inverters and can run many appliances, including lights, TVs, toasters and other small kitchen appliances. However, the main considerations for the appliances that can be run by a 5000W inverter are the continuous power and surge capacity of the inverter.

Continuous Power: A 5000W inverter has a continuous power of 5000W, which means that it can provide 5000W of power continuously to power the appliance. You just need to make sure that when the 5000W inverter is in use, the total power of the loads connected to it should not exceed 5000W, which can effectively prevent the 5000W inverter from being overloaded.

Surge Capacity: The surge capacity of an inverter refers to the inverter’s ability to provide an output that exceeds the rated power for a short period of time, which is usually measured by using a multiple of the surge capacity versus the time it can last. Take DEYE’s inverter as an example, the surge power of its inverter is twice of the rated power and can last for 8s.

For the inverter’s surge capacity as long as it is related to the inductive devices, because the inductive devices may start up with 2 times to 5 times the rated power, which means that the starting power of the inductive devices needs to be taken into consideration with the inverter’s surge power, in order to determine exactly what appliances can be run by the 5000W inverter.

3. How many solar panels does the 5000W inverter support?

Determine the maximum output power of the inverter; for 5000W inverter, its rated power is not equal to its maximum output power, and the maximum output power of the inverter will be larger than the rated power, the maximum output power of 5000W inverter is about 5500W.

The power of your solar panels: In the home solar panels, 300W and 550W are more common, their size and weight are within the acceptable range of the roof or ground.

Once you know the above two figures, you can calculate it by the following formula

Number of solar panels = Maximum PV input power of the inverter / Power of the solar panels

For example, the maximum PV input power of your 5000W inverter is about 5500W, and the power of the solar panels you choose is 550W, then your 5000W inverter can support 5500W/550W = 10 blocks. Therefore, 10 solar panels of 550W can fulfill the power demand of your 5000W inverter.

However, for some cases, the result of this calculation is not accurate, if you want to further determine the number of solar panels that the 5000W inverter can support, you also have to compare the maximum input current of the inverter with the maximum open-circuit voltage and the current and voltage of the solar panels, in order to calculate a more correct number of solar panels.

Conclusion:

5000W inverters are widely used in home, car and so on to provide stable power support, 5000W inverters become an indispensable part of solar energy system with high efficiency and safety. However, when you are going to buy 5000W inverter, you need to understand the above mentioned parameters clearly in order to help you better choose the suitable 5000W inverter.
