Our verdict

Is an Alpha ESS inverter right for you?

Capable hybrid systems at a low price, with a local office. Owner feedback on support is mixed, and it doesn't feature in installer votes or the installation rankings.

Rated 6.3/10, #8 of 9 brands we rate for inverters.

A good fit if

  • Budget matters most
  • You want an inverter and battery from one brand

Maybe look elsewhere if

  • Responsive after-sales support is a priority

What we like

  • Low price

    Among the cheapest grid-approved hybrid systems.

  • Three-phase option

    SMILE-G3 T scores well on efficiency and MPPTs.

Worth weighing up

  • Support reports

    SolarQuotes reports mixed owner feedback on warranty and technical support.

  • Not listed

    Privately held, with no installer-vote or SunWiz placing.

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.
