Inverter Selection

Choose an On-Grid Inverter by Project Type

Grid-tie inverters convert solar DC power into utility-synchronized AC power. We offer options for single-phase installations, three-phase commercial systems and larger distributed PV arrays. Select the power rating and electrical configuration that match your project.

Single-Phase Grid-Tie Inverters

Suitable for smaller grid-connected PV installations where single-phase service is permitted. Selection depends on AC voltage, PV input limits and grid rules.

Three-Phase String Inverters

Designed for commercial rooftops and distributed PV systems. MPPT allocation, string design and three-phase grid requirements guide model selection.

View 20kW Inverter →

Large Commercial String Inverters

Higher-power arrays require appropriate PV input capacity, AC collection, grid protection, communications and installation access.

Engineering Compatibility

Six Checks for Grid-Tie Inverter Selection

1. Grid Phase and AC Voltage

Match single-phase or three-phase output to the site connection. AC voltage, frequency, neutral arrangement and utility requirements vary by market.

2. Maximum PV DC Voltage

Calculate string open-circuit voltage at the lowest expected cell temperature. The result must remain below the inverter's DC input limit.

3. MPPT Operating Window

Compare the PV string operating voltage across expected temperatures with the inverter's MPPT start-up and operating ranges.

4. MPPT Input Current

Check module Imp and Isc against the inverter's per-input current limits, including parallel-string arrangements and high-current PV modules.

5. Grid Protection and Certification

Review anti-islanding, voltage and frequency protection, export control and grid-code documentation for the selected model and destination.

6. Monitoring and Installation

Evaluate communication interfaces, monitoring options, enclosure protection, cooling clearances and maintenance access.

Project Applications

On-Grid Inverter Applications

Residential Rooftop PV

Single-phase grid-tie inverters can serve smaller residential systems when the building connection and local utility rules allow installation.

Commercial and Industrial Rooftops

Three-phase string inverters support commercial PV designs with multiple roof orientations, module strings and site-specific export requirements.

Ground-Mounted PV Arrays

Larger PV plants use inverter configurations coordinated with AC collection, protection, grid connection and monitoring systems.

A conventional on-grid inverter does not automatically provide backup power during an outage. Backup or battery operation requires a compatible system design.

Buyer Questions

On-Grid Solar Inverter FAQ

  • What is the difference between on-grid and hybrid inverters?

    An on-grid inverter converts PV electricity for grid-connected use and normally stops exporting during a utility outage. A hybrid inverter may also manage battery storage and backup loads, depending on its design and configuration.

  • Should I choose a single-phase or three-phase solar inverter?

    The choice depends on the property's electrical service, required AC power, export limits and utility rules. Commercial projects commonly use three-phase equipment, while smaller installations may use single-phase models where permitted.

  • How do I match solar panel strings to an on-grid inverter?

    Calculate maximum cold-weather string Voc, operating Vmp and module current. Compare these with the inverter's maximum DC voltage, MPPT operating range and input-current limits.

  • Can an on-grid inverter export excess solar electricity?

    Export may be possible when the inverter, metering, protection equipment and utility connection agreement permit it. Export limits and zero-export settings depend on the project and local rules.

  • Which certifications are needed for grid-tie inverters?

    Requirements vary by destination country and grid operator. Safety and grid-code approvals must cover the exact inverter model and planned grid connection conditions.

  • What information do you need for a wholesale inverter quote?

    Send the inverter power class, quantity, grid phase and voltage, PV module or string details, destination country, required certificates and target delivery schedule.
