Questions to ask installers about the X1-Boost G4

Is it a hybrid (battery-ready) inverter, or solar only?
How much solar can it take, and how many separate panel inputs (MPPTs) does it have?
Is it single- or three-phase, and does that suit my home's supply?
Does it meet my network's export limit, and does it support dynamic export?
If I add a battery later, which batteries will it work with?
What's the warranty, and who handles claims in Australia?

Our inverter guide explains each of these, and hybrid inverters covers adding a battery.
