Sizing an inverter involves determining the appropriate capacity or rating of the inverter for a specific application. The sizing process depends on several factors, including the load requirements, the type of load, and any additional considerations such as efficiency, power factor, and future expansion. Here’s a general guide on how to size an inverter: Determine the load requirements:

Start by identifying the electrical load that the inverter will power. Determine the load’s voltage and power requirements, including both the continuous power (Watts) and the peak power (surge Watts) if applicable. Make a list of all the loads that will be connected to the inverter. Calculate the total power requirement:

Add up the continuous power requirements of all the loads that will be connected to the inverter. If there are any loads with surge power requirements, take note of the highest surge power value. This will give you an estimate of the total power requirement for the inverter. Consider efficiency and power factor:

Inverters have an efficiency rating that represents how effectively they convert DC power (from a battery or solar panels) to AC power. Consider the efficiency of the inverter you are evaluating and account for it when sizing the inverter. Additionally, if your loads have a low power factor, you may need to oversize the inverter to compensate for the reactive power. Account for future expansion:

If you anticipate adding more loads in the future, it’s a good idea to account for that in your sizing calculations. Add a safety margin to the power requirements to allow for future growth. Select the appropriate inverter rating:

Once you have determined the total power requirement, consider the available inverter ratings on the market. Inverters typically come in standard power ratings, such as 1kW, 2kW, 5kW, etc. Choose an inverter rating that is equal to or slightly higher than your total power requirement. It’s generally better to select an inverter with a slightly higher rating to provide some headroom and prevent overloading. Consider other factors:

Depending on your specific application, you may need to consider additional factors such as the type of inverter (pure sine wave or modified sine wave), input voltage range compatibility with your power source, inverter’s input and output voltage requirements, and any specific features or functions required for your application (e.g., grid tie capability, battery charging, etc.). It’s important to consult the manufacturer’s specifications, guidelines, and technical documentation for the specific inverter model you are considering, as they may have specific recommendations and requirements for sizing. Remember, if you’re not confident in your ability to size an inverter correctly, it’s always recommended to seek the assistance of a qualified professional or an electrical engineer who can assess your specific needs and provide accurate sizing recommendati

There is no one price for inverter installations. The price of installing inverter can start from R17000 to a much higher amount depending on few factors as listed below Size of the inverter: The bigger the inverter the more expensive it gets. also the battery required will be much bigger. Note with inverter installations that the battery is the most expensive part of the whole system. Its advisable to have your inverter sized properly by epxerience installer so that you get the inverter that fit-for-purpose, high quality, meet standards and cost-effective.
