Solar Inverters

Controlling Maximum Power Output

Solar inverters in South Africa are responsible for continually tracking your solar array’s voltage to figure out the maximum power at which your solar panels operate, ensuring the system produces the most and cleanest power at all times.

There are many different sizes available for inverters. The size required is dependent on the size of the solar panels installed. For example, a 5kW solar power system would require an inverter of similar or larger capacity. At its most basic level, it must be equipped to manage the maximum amount of power the system could generate.

What is the Lifespan of a Solar Inverter?

The lifespan of a solar inverter can vary depending on a number of factors, including:

• Quality of the inverter
• Conditions it is exposed to
• How well it is maintained over time

In general, a high-quality solar inverter should last for at least 10 years, and many can last for up to 20 years or more with proper care.

One of the main factors that can affect the lifespan of a solar inverter is the quality of its components. Cheaper inverters often use lower-quality components that are more prone to failure, which can result in a shorter lifespan overall. On the other hand, higher-end inverters may use more durable components that are designed to last longer, even in harsh conditions.

Another factor that can affect the lifespan of a solar inverter is the environment it is installed in. Inverters that are exposed to extreme temperatures, high humidity, or other harsh conditions may experience more wear and tear over time, which can lead to a shorter lifespan. Similarly, inverters that are exposed to direct sunlight or other forms of weathering may degrade more quickly than those that are installed in more protected locations.

How do I Calculate What Size Inverter I Need?

To calculate the size of inverter you need, there are a few key factors you will need to consider. Here are the steps you can follow:

1. Determine your power requirements: First, you will need to calculate the total amount of power your system will need to supply. This will include all of the electrical appliances and devices you plan to use, as well as any surge currents they may require.
2. Determine your voltage requirements: Next, you will need to determine the voltage of the batteries you plan to use. This will typically be either 12, 24, or 48 volts.
3. Calculate your total power requirements: Multiply your power requirements by the number of hours you plan to use the system each day. This will give you your daily energy requirements in watt-hours (Wh).
4. Size your inverter: To determine the size of the inverter you need, you will need to choose one that is capable of handling your peak power demands. To do this, add up the maximum wattage of all of the devices you plan to use at the same time. Then, choose an inverter that is rated for at least this amount of power.
5. Consider efficiency: Finally, it’s important to consider the efficiency of the inverter you choose. Inverters typically have an efficiency rating that indicates how much of the power they consume is converted into usable power. To ensure that you get the most out of your system, look for an inverter with a high-efficiency rating.

By following these steps, you should be able to determine the size of inverter you need to power your system effectively and efficiently. However, if you have any doubts or concerns, it’s always best to consult with a professional to ensure that you choose the right equipment for your needs.

Solar Inverter Prices in South Africa

The price of solar inverters vary depending on the brand, type, and specifications, but they typically range from around R2,000 to over R80,000. However, it is important to note that the cost of the inverter is only one aspect to consider when installing a solar system. Other factors to consider include the size of the solar panel system, electricity usage, and the specific needs of the individual or business. Therefore, it is recommended to consult with a professional installer or supplier to determine the most appropriate and cost-effective solar inverter for your specific requirements.

1. Deye – R25,000 to R70,000 (5kW – 16kW)
2. Sunsynk – R25,000 to R150,000 (5kW – 50kW)
3. SMA Solar Technology – R8,000 to R60,000 (1.5 kW – 25 kW)
4. Fronius – R12,000 to R75,000 (1.5 kW – 27 kW)
5. ABB (now FIMER) – R10,000 to R70,000 (1.2 kW – 50 kW)
6. Victron Energy – R6,000 to R80,000 (500 VA – 15 kVA)
7. Growatt – R4,000 to R40,000 (1 kW – 20 kW)
8. GoodWe – R6,000 to R50,000 (1 kW – 25 kW)
9. SolaX Power – R8,000 to R30,000 (1 kW – 10 kW)
10. Schneider Electric – R20,000 to R120,000 (3 kW – 80 kW)
11. Huawei – R10,000 to R60,000 (2 kW – 33 kW)
12. Sungrow – R6,000 to R50,000 (1 kW – 25 kW)

Please note that these prices are approximate and may change over time or based on different suppliers. It’s essential to research and compare prices from various suppliers to find the best deal for your specific needs. Don’t forget to factor in installation costs and potential government incentives or rebates that can help offset the overall cost of a solar inverter system.
