Our verdict

Is a Sigenergy inverter right for you?

Excellent, modern hardware that installers rate highly. It's a young company and had a recall in 2025, handled with replacements, so the track record is still building.

Rated 7.5/10, #4 of 9 brands we rate for inverters.

A good fit if

  • You want a modern, all-in-one system you can expand
  • You're adding a battery now or soon

Maybe look elsewhere if

  • You want a brand with a long history

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.

    The AC plugs may overheat and become damaged, posing a risk of fire. Firmware limits sustained output until a replacement controller with an updated plug is fitted, plus an extra 2-year warranty.
