How much does a solar inverter cost?

A good-quality 5kW single-phase solar inverter costs $1,320 – $2,500. A 3-phase solar inverter costs between $1,900 and $2,300, depending on the quality. While inverters have a 15-year lifespan, but some makes and models are more reliable than others. Speak to your local installer about the best brands and models currently available.

How much does a 5kw solar inverter cost?

For example, decent-quality 5kW solar inverters, which can support up to 6.6kW of panels, start at $1,000 for budget single-phase models (e.g., Sungrow, Goodwe, or Solis) and up to $2,000 for premium single-phase models (e.g., Fronius or SMA). If you want a 3-phase, 5kW inverter; add around $400 to those prices.

Can a 5kw inverter be used with a 6.6kw Solar System?

For example, a 5kW inverter is suitable for use with a 6.6kW solar system. There are system losses as solar panels convert sunlight to electricity. It allows for the use of lower-rated inverters. Make sure that the inverter you buy has a long enough warranty.

How much does a 5kw Solar System cost?

The price of a 6.6kW system with a 5kW inverter is the same as for a 6.6kW system, expect to pay between $5,500 - $8,000. The cost of installing a 6.6kW system vs a 5kW system is negligible. For the extra system capacity, you are only paying more for the solar panels and some small additional installation costs.
