Our verdict

Is a Fox ESS inverter right for you?

Well-specified hybrids at sharp prices, with seven-day phone support. Fox ESS is young, so its long-term record in Australia is still being written.

Rated 6.8/10, #6 of 9 brands we rate for inverters.

A good fit if

  • You want good specs at a good price
  • Weekend support matters to you

Maybe look elsewhere if

  • You want a brand with a long Australian history

What we like

  • Strong specs

    H3 Smart and 1K5 hybrids score highly on efficiency, MPPTs and heat.

  • Seven-day support

    Melbourne and Sydney offices, 1300 number, weekend hours.

Worth weighing up

  • Young brand

    Founded 2019, selling here since 2021.

  • Many overlapping ranges

    Make sure you know which series you're being quoted.

Questions to ask your installer

  1. 1Is this a hybrid, and which batteries can I add later?
  2. 2How many MPPTs, and which roof faces go on each?
  3. 3Can I see the warranty letter, and who services it locally?

A good installer will be glad you asked, whichever brand you choose.
