5-10kW | Single-phase String Inverter
The Solis S6-GR1P(5-10)K03-NV-ND-AU is a new-generation single-phase string inverter built for Australian homes. It comes in seven power ratings from 5kW to 10kW and has three MPPTs, so it suits homes with panels spread across several roof faces. It also includes zero-export control and 24-hour load monitoring. But how does it stack up?
Key features of the Solis S6-GR1P(5-10)K03-NV-ND-AU Inverter
- 3 MPPT design: Three independent maximum power point trackers let panels on east, west and north-facing roofs each run at their best, increasing total solar output.
- High string current: Each MPPT accepts up to 20A input current, so the inverter works with today’s larger, high-current solar panels.
- Wide operating voltage range: A low 60V start-up voltage and an MPPT range of 50–500V mean the inverter starts generating earlier in the morning and keeps working in low light.
- Export power control: An integrated CT and meter interface supports zero-export and export-limiting settings to meet network rules.
- 24-hour load consumption monitoring: With a CT or smart meter, you can see how much energy your home uses day and night, not just how much your panels produce.
- AFCI protection: Optional integrated AFCI 2.0 arc-fault detection helps reduce the risk of electrical fires.
- Built for Australian conditions: An IP66 rating, natural cooling and a -25°C to +60°C operating range make it suitable for outdoor installation. It also runs quietly, at under 40 dB(A).
- Easy setup and monitoring: An LED display and Bluetooth app connection simplify commissioning. Optional Wi-Fi or GPRS loggers add remote monitoring.

Applications for the Solis S6-GR1P(5-10)K03-NV-ND-AU Inverter
The Solis S6-GR1P(5-10)K03-NV-ND-AU is well-suited for:
- Residential homes: Ideal for households on single-phase power that want a mid-to-large solar system to reduce electricity bills.
- Complex or multi-facing roofs: The three MPPTs make it a strong fit for homes with panels on several roof orientations or with partial shading.
- Export-limited networks: Built-in export control makes it easier to meet local network export limits.
Pros of the Solis S6-GR1P(5-10)K03-NV-ND-AU Inverter
- Flexible system design: Three MPPTs and seven power ratings give installers plenty of options to match the inverter to the roof and household.
- Panel-ready: 20A per MPPT supports the latest high-output solar panels.
- High efficiency: Up to 98.0% peak efficiency maximises the energy you get from your panels.
- Smart energy management: Export control and 24-hour consumption monitoring are built in, with no extra hardware beyond a CT or meter.
- Safety-focused: Optional AFCI, an integrated DC switch and a full suite of protection functions.
- Durable and quiet: IP66-rated and runs at under 40 dB(A).
Cons of the Solis S6-GR1P(5-10)K03-NV-ND-AU Inverter
- No battery integration: This is a grid-tied inverter. Adding a battery later requires an AC-coupled inverter, such as the Solis S6-EA1P(3.6-6)K-L, or a hybrid inverter instead.
- AFCI is optional: Arc-fault protection isn’t standard on every unit, so check with your installer if it’s a priority.
- Heavier than smaller models: At around 16 kg, it’s heavier than compact inverters like the Solis Mini Series.
- Network limits may apply: Some networks cap single-phase inverter size or export, so check with your installer before choosing the larger models.
Is the Solis S6-GR1P(5-10)K03-NV-ND-AU Inverter right for you?
The Solis S6-GR1P(5-10)K03-NV-ND-AU is an excellent choice for:
- Medium-to-large residential systems: If you have a single-phase home and want a 5–10kW solar system, this range covers most needs.
- Homes with multiple roof orientations: Three MPPTs help you get the most out of every roof face.
- Energy-conscious households: Built-in consumption monitoring helps you understand and reduce your energy use.
However, if you plan to add a home battery, you may want to consider a Solis hybrid inverter from the start.
