Solar Inverters Perth

What are Solar Inverters? Solar inverters are one of the most important components of a solar energy system. They convert direct current (DC) electricity generated by solar panels into alternating current (AC) electricity – which is the type of electricity used in Perth homes and businesses.

Solar inverters are essential for grid-connected solar systems, which allow Perth homeowners to sell excess solar energy back to Synergy (here’s their take on solar). Inverters are also used in off-grid solar systems, which store solar energy in batteries for use at night or when the grid is down.

Solar is a great investment for your home. There are many types of solar inverters and we have a wide selection of solar inverters for every system.

How many panels can a 10kW inverter handle?

The number of solar panels that a 10kW inverter can handle depends on the voltage and wattage of the solar panels. For example, if the solar panels are 250 watts and 24 volts, then the inverter can handle up to 40 solar panels. However, if the solar panels are 300 watts and 36 volts, then the inverter can only handle up to 33 solar panels.

To calculate the number of solar panels that a 10kW inverter can handle, you can use the following formula:

Number of solar panels = Inverter capacity (in watts) / Solar panel wattage (in watts)
What size inverter do I need for 5kW solar system?

For a 5kW solar system, you will need a 5kW inverter. This is the general rule of thumb, and it is important to follow it to ensure that your solar system is operating efficiently and safely.

However, there are a few things to keep in mind when choosing an inverter size for your solar system:

  • Oversizing your inverter: You can oversize your inverter by up to 33%. This means that you could use a 6.6kW inverter for a 5kW solar system. This can be beneficial if you plan on expanding your solar system in the future, or if you have a lot of shade on your roof. However, it is important to note that oversizing your inverter can reduce its efficiency.
  • Undersizing your inverter: It is not recommended to undersize your inverter. This can cause the inverter to overheat and shut down. It can also reduce the lifespan of your inverter.
  • Type of inverter: There are two main flavours of solar inverters: string inverters and solar micro inverters. String inverters are more common and less expensive, but microinverters offer several advantages, such as increased efficiency and shade tolerance.
