Three figures govern it, all in the Technical Specifications: the MPPT voltage range, the maximum input voltage and the maximum DC power. Tell us which panel you're pairing it with and we'll confirm the string layout.

G98 covers installations up to 3.68kW per phase and is notified to your DNO after commissioning. Anything larger needs G99 approval agreed beforehand. We can flag which one your design falls under.

A hybrid inverter takes a DC-coupled battery directly. A standard string inverter needs an AC-coupled battery alongside it. The Technical Specifications show which type this unit is.

Yes, up to the maximum DC power figure in the specifications. Modest oversizing is normal practice - it lifts output in winter and at either end of the day, at the cost of brief clipping at midday peak.

An MPPT tracks the optimum operating point for a string of panels. You want one per roof orientation or pitch, because panels facing different directions on a single tracker drag each other down.

The standard manufacturer warranty is listed under the Warranty tab. Extended cover is available on most brands - see Warranty Extensions.
