At 6 kg and roughly A4 size, this is one of the smallest 3 kW inverters, and it includes arc-fault protection and a longer warranty than most. It has a single MPPT tracker, so it works best when all your panels face the same way with no shade.
If your roof has two faces or partial shade, a two-tracker inverter such as the Growatt MIN 3000TL-X is the better fit.
