Three-Phase (Trio) Inverters

Trio series three-phase inverters

The Trio series consists of on-grid inverters that work compatibly with a 400 V three-phase grid. The catalog includes the Trio Atom series in power steps such as 4, 5 and 10 kW; higher steps are also in the product list. A three-phase connection is the standard choice for load balance between phases and for high-power systems.

Selection criteria

• Power step: The ratio between installed panel power and inverter AC power is determined according to the project.
• Number of MPPTs: If roof surfaces face different directions, each direction is connected to a separate MPPT input.
• Grid protection: The distribution company's connection conditions and protection settings must be included in the project.
• Monitoring: In facilities with multiple inverters, central monitoring and communication accessories make operation easier.

Areas of use

Villas, hotels, workshops, warehouses and agricultural businesses are places where three-phase electricity use is common. In these facilities, the overlap of daytime consumption with solar production creates an advantage for self-consumption.

Reminder for Antalya

In tourism facilities where the air conditioning load increases in summer, the production and consumption profiles fall at similar hours. This makes reviewing consumption data valuable for sizing the inverter correctly.

String design

Because three-phase inverters have multiple MPPT inputs, different roof surfaces can be split into independent strings. The number and orientation of panels on each MPPT input are kept as identical as possible. Protection elements such as fuses, surge arresters and isolators on the DC side are included in the project.

In projects where more than one inverter is used in the same facility, the production of each device can be monitored separately and the total power is compared with the limits in the grid specification. After installation, phase sequence and grounding continuity are verified by measurement.
