Questions to ask installers about the SDT G3
- 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.
