What This Model Is Best For

A Three Phase three-phase on-grid inverter covering 3-12 kW, the entry point into three-phase PV for residential and small commercial rooftops below the R6 power tier. The 160 – 950 V MPPT range handles a wide variety of module string voltages, and 3L+N+PE grid output suits standard three-phase installations.

98.3%

  • Same compact wall-mount footprint as lower-power R5 single-phase units
  • Dual MPPT design enables mixed-orientation rooftop arrays with independent tracking
Technical & Grid Integration Specs
Grid IntegrationVDE-AR-N 4105, G99, EN 50549-1; active power control and Q(U) curve support
DC/AC ConfigurationUp to 1.5 DC/AC ratio with programmable active power derating
CommunicationRS485 Modbus RTU native, optional Wi-Fi/4G dongle for cloud monitoring
Surge ProtectionType II AC/DC surge protection, AFCI arc-fault detection optional

Use this model when…

  • The site requires a dedicated three-phase output up to 12 kW in compact footprint
  • The string current matches module specs with zero clipping risks
  • The installer has confirmed the matching local grid-code certifications

Choose another model when…

  • The total string open-circuit voltage exceeds safety limits
  • A different grid phase or system-level battery topology is required
  • Local regulations demand centralized substation inverter architectures

Quote-prep checklist

  • Verify grid operator's active power limitation requirements before commissioning
  • Ensure mixed-orientation strings are split across separate MPPT inputs
  • Confirm AFCI requirement based on local fire-code jurisdiction

Where This Model Fits Best

Three application scenarios for the R5-3k~12k Three Phase On-grid Inverter, showing where this 3-12 kW product belongs on the shortlist and where it does not. Review these before quote approval.

R5 urban rooftop application
01

Small Three-Phase Residential Rooftop

For residential homes with three-phase supply, this 3-12 kW model is the entry point for three-phase on-grid PV before stepping up to the R6 series. It provides enough power for a typical residential three-phase installation.

  • Three-phase grid meter confirmed at the property
  • AC output target within 3-12kW
  • MPPT voltage 160-950V compatible with string design

If your project is at 10-12kW, also review R6 15-25kW before making a final decision.

R5 mid-sized commercial rooftops application
02

Small Commercial Three-Phase PV

For small office buildings, retail units, or workshops with three-phase power, this inverter handles PV capacity up to 12kW. If the project needs more than 12kW, review R6 15-25kW.

  • Site electrical load and consumption profile
  • Three-phase grid-code requirements for the destination country
  • PV array design within MPPT and current limits

Projects near 12kW should be assessed for future expansion. R6 may provide headroom.

R5 application overview
03

R5-to-R6 Upgrade Boundary Project

When a project is at the boundary between R5 three-phase and R6 15-25kW: is the target AC output clearly above 12kW? If 10-12kW and you need 180-1000V MPPT or 32A string current, R6 may be the better fit. Review both datasheets.

  • Target AC output: below 12kW or above? confirmed
  • R5 3-12kW datasheet reviewed
  • R6 15-25kW datasheet reviewed for comparison
  • Grid-code compliance confirmed for selected model

This is a model-tier boundary. Do not guess — review both datasheets and confirm the numbers.

FAQ for Technical Review

Product-specific technical questions for buyers, installers, and distributors reviewing the R5-3k~12k Three Phase On-grid Inverter before quotation. Each answer includes technical criteria, a pre-quote checklist, and a caveat to avoid common procurement mistakes.

Is the R5 3-12kW the right three-phase on-grid inverter for my project?

Confirm your AC output target falls within 3-12 kW and that you have a three-phase grid connection (3L + N + PE, 220/380 – 240/415 V). If your project is above 12kW, review the R6 15-25kW model. If it is below 12kW but you only have single-phase, review the R5 single-phase range.

What to check

  • Confirm AC output target within 3-12 kW
  • Confirm three-phase grid connection available
  • Confirm MPPT voltage (160-950V) covers your module string
  • Review the R5-(0.7K-8K)-S2-15_User_Manual_en User Manual

If the project is at 10-12kW, also review the R6 15-25kW datasheet before making a final decision.

When should I choose R5 3-12kW instead of R6 15-25kW?

Choose the R5 3-12kW when your project needs 3-12kW three-phase output without the higher string current (32A) or wider MPPT range (180-1000V) of the R6. If your project is clearly in the 15-25kW range, or you need 32A string current and AFCI capability, move to the R6.

What to check

  • Confirm power target: 12kW or below
  • Confirm that 160-950V MPPT range is sufficient
  • Compare R5 3-12kW and R6 15-25kW datasheets

This is a power-tier boundary decision. Review both datasheets if uncertain.

What documents are needed before the R5 3-12kW quote?

Review the R5-(0.7K-8K)-S2-15_User_Manual_en User Manual for electrical specifications and the R5-3K-12K-Three-Phase-On-grid-Invereter-Datasheet for installation and wiring. Share the datasheet with the installer before quoting.

What to check

  • Review R5-(0.7K-8K)-S2-15_User_Manual_en User Manual
  • Review R5-3K-12K-Three-Phase-On-grid-Invereter-Datasheet for installation details
  • Confirm grid-code compliance for destination country

Technical review against the datasheet prevents specification misunderstandings during the quote process.

What project data should I send for a faster R5 3-12kW quote?

Send the destination country, AC output target, module specifications, and grid-code requirements. If the project is near the R6 boundary, note that so the quote can include both R5 and R6 options.

What to check

  • Destination country and grid code
  • AC output target and module specifications
  • Whether R6 15-25kW comparison is needed
  • Expected quantity and schedule

Do not send unsupported claims or unverified project data. Sunriver will confirm the technical fit before quoting.

What monitoring setup is available for the R5 3-12kW?

The R5 three-phase series supports communication via . Confirm Wi-Fi or Ethernet availability at the site and discuss the preferred monitoring app or portal with Sunriver before ordering.

What to check

  • Confirm communication path (Wi-Fi, Ethernet, 4G)
  • Verify site connectivity
  • Confirm monitoring portal access requirements

Remote monitoring configuration should be confirmed during the quote process, not after installation.
