A hybrid inverter performs all the functions of a traditional PV inverter — converting direct current from solar panels into alternating current for household use — but adds the ability to manage a storage system, communicating with batteries via dedicated ports (CAN/RS485).

There are three concrete advantages compared to a traditional inverter: maximized self-consumption, because excess solar energy is not fed into the grid but stored for hours without sun; partial or total independence, with the ability to operate in off-grid mode during blackouts thanks to the integrated switch with a transfer time of less than 10ms; economic optimization, thanks to the AI-EMS which automatically regulates charging and discharging based on tariff bands, reducing electricity costs.

Yes. The Flexi 3.0 Trifase 36-50kW is certified according to European grid connection standards, including EN50549-1 and C10/C11, which are exactly the standards required by the GSE (Gestore dei Servizi Energetici) for access to Italian state incentives, including net metering.

In addition to these, it holds VDE-AR-N4105 and VDE0126 certifications, recognized in Italy, as well as IEC62109-1/-2 safety standards. The inverter also integrates anti-reflux protection, an essential function for those participating in the net metering mechanism: without it, energy fed into the grid could not be correctly accounted for. For definitive confirmation of compatibility with your local distributor, it is always advisable to check with your installer.

The main difference lies in power and sizing: 20-30kW models are aimed at the high-end residential segment and small businesses, while 36-50kW models are clearly positioned for light commercial and medium to large-scale storage applications.

Comparing technical data, 36-50kW models feature 4 MPPT trackers with 8 strings, with a battery current up to 120A and a maximum charge/discharge power of 60kW;

20-30kW models, on the other hand, offer 2 MPPT trackers with 4 strings, with a maximum battery current of 60A and a maximum charge/discharge power of 30kW.

The difference is also reflected in size and weight: 36-50kW models (867×715×306mm, 81kg) are significantly larger and heavier than 20-30kW models (558×535×260mm, 29-36kg).

Both support lithium, lead-acid, and sodium chloride batteries with a voltage of 150-800V.

The fundamental difference lies in the presence or absence of the battery port and storage function: the GONEO string inverter (Flexi 3.0 Three-Phase - PV String Inverter) exclusively converts DC energy from the panels into AC, without managing batteries. The hybrid inverter (Flexi 3.0 Three-Phase - Hybrid Storage Inverter) adds the ability to connect and manage a storage system to this function.

The string inverter is the right choice for those with an existing PV system without storage and no intention of installing it in the future — it focuses on maximizing production with high MPPT efficiency (>99%) and stable output up to 60kW.

The hybrid inverter, on the other hand, is the complete solution for those who want to build an integrated energy system: it manages PV, batteries, and loads in a coordinated manner, with backup and tariff optimization functions. In summary: the string inverter is a pure converter, the hybrid is a true energy manager.
