What size inverter do I Need?
The right size inverter for your specific application depends on how much wattage your devices require. This information is usually printed somewhere on electronic devices, although it may show voltage and amperage ratings instead.
How much power does an inverter use?
Most inverters have an efficiency of between 60% and 80%. This efficiency can also be referred to as the power factor of an inverter. For our calculations, we would use a power factor of 0.8. Hence, Power supplied (or VA rating of the inverter) = Power consumed by equipment in watts / Power factor
What are the different solar inverter sizes?

During our research, we discovered that most inverters range in size from 300 watts up to over 3000 watts. In this article, we guide you through the different inverter sizes.
How to choose an inverter?
To choose an inverter, you need to consider 6 key factors: Maximum power rate. DC to AC ratio. Input voltage. Operating frequency. Inverter type. Output voltage. Let’s delve into these factors a little more. The maximum power rate means how much DC and AC power the inverter can handle.
How do I calculate a power inverter size?
To use this calculator, input details such as total power consumption, voltage, and the type of appliances to be powered. For instance, calculating the inverter size for a 1500W load requires considering factors like the inverter’s efficiency, battery capacity, and peak load.
Why should you choose an inverter size that's at least 20% larger?
Choose an inverter size that’s at least 20% larger than the total calculated wattage to ensure top performance. This allows for fluctuations in power demand and provides a safety margin.
