Fronius Verto Plus is a current three-phase hybrid inverter for larger residential and commercial systems. It combines PV conversion, a high-voltage battery interface and three-phase backup capability. It is a separate product from the PV-only Verto.
Power and PV inputs
The current UK family has 15, 17.5, 20, 25, 30 and 33.3 kW power classes. All have three MPPTs with two string inputs per tracker, a 150 to 870 V tracking range and a 1,000 V maximum DC input.
Those family figures do not set one universal string current. The exact power-class datasheet supplies its current limits.
Every listed power class is a three-phase inverter.
Battery and backup
Verto Plus has a high-voltage battery interface for compatible Fronius batteries.
Full Backup requires a compatible battery and the approved grid-disconnection arrangement; it is not active from the inverter alone.
Protection and installation
Verto Plus includes arc-fault detection, type 1+2 DC surge protection and type 2 AC surge protection. The enclosure is IP66.
