Technical FAQs 4

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.
