8-15kW | Three-phase Low Voltage Hybrid Inverter
The Solis S6-EH3P(8-15)K02-NV-YD-L-AU is part of Solis’s Solarator Series, a range of three-phase hybrid inverters built for low-voltage (48V) batteries. It comes in five ratings from 8kW to 15kW and is designed for large homes that want dependable backup power, even where the grid is unreliable. It works on-grid and off-grid and can run alongside generators and existing solar systems. So how does it measure up?
Key features of the Solis S6-EH3P(8-15)K02-NV-YD-L-AU Hybrid Inverter
- Solar oversizing: Supports PV input of up to 160% of the inverter’s rated DC power, so you can install more panels and capture more sunlight.
- High-current PV inputs: Up to 20A per string makes it compatible with the latest high-power solar panels.
- 200% overload capacity: In off-grid mode it delivers twice its rated power for 10 seconds, helping motors, water pumps and air conditioners start reliably.
- Seamless backup switching: It switches from grid to backup power in under 10ms, keeping appliances running during a blackout.
- DC and AC coupling: It can connect to solar panels directly or to an existing grid-tied solar system, making it easy to expand PV or add a battery to current solar.
- Generator integration: Multiple generator connection methods with automatic control.
- Parallel operation: Up to six units can run in parallel to expand system capacity.
- Customisable backup reserve: Set how much battery charge is held back for outages.
- PV-only off-grid operation: It can run from solar alone without a battery, reducing upfront costs.
- AI-powered and VPP-ready: It supports smart energy optimisation and virtual power plant participation.
- 7-inch LCD screen: A large industrial-grade display makes local monitoring and settings easy.
- IP66 rated: Built for outdoor installation in harsh Australian conditions.

Applications for the Solis S6-EH3P(8-15)K02-NV-YD-L-AU Hybrid Inverter
The Solis S6-EH3P(8-15)K02-NV-YD-L-AU is well-suited for:
- Large three-phase homes: Ideal for households with three-phase power and high energy use, such as those with EVs, pools or ducted air conditioning.
- Areas with unreliable grid supply: A strong option for regional and rural properties that experience frequent outages.
- Homes with existing solar: Suits households that want to add battery storage without replacing their current solar system.
Pros of the Solis S6-EH3P(8-15)K02-NV-YD-L-AU Hybrid Inverter
- Handles unbalanced loads: It supports different loads on each phase, which suits typical homes where most appliances run on a single phase.
- Dual battery ports: Two battery inputs make it easier to connect larger battery banks, with charge and discharge currents of up to 290A.
- Efficient energy storage: 95.0% PV-to-battery charging and 94.5% battery discharge efficiency keep storage losses low.
- High grid passthrough: Up to 50A of grid power can pass through the inverter to your backed-up loads when the grid is available.
- Advanced safety monitoring: Insulation resistance monitoring, residual current detection, Type II DC surge protection and an isolated battery side add extra protection.
- Wired and wireless connectivity: Wi-Fi, LAN and Bluetooth come standard, with 2G/3G/4G available for sites with poor internet.
Cons of the Solis S6-EH3P(8-15)K02-NV-YD-L-AU Hybrid Inverter
- Heavy: At 42 kg, it needs a solid mounting wall and may take two people to install.
- Fan noise: Fan cooling runs at up to 65 dB(A), so it’s best installed away from bedrooms and living areas.
- Only two MPPTs: Homes with panels across three or more roof orientations may lose some output compared with a three-MPPT inverter.
- Low-voltage battery only: It won’t work with high-voltage batteries, and low-voltage systems need heavier cabling.
- AFCI is optional: Arc-fault protection isn’t standard on every unit, so check with your installer.
- Three-phase only: Single-phase homes will need a different model, such as the Solis S6-EH1P(10-16)K03-NV-YD-L-AU.
Is the Solis S6-EH3P(8-15)K02-NV-YD-L-AU Hybrid Inverter right for you?
The Solis S6-EH3P(8-15)K02-NV-YD-L-AU is an excellent choice for:
- Three-phase households wanting whole-home backup: If you want your entire home, not just a few circuits, to keep running during outages, this range has the capacity to do it.
- Homeowners planning to expand: If you expect to add more panels, batteries or inverters over time, this system can grow with you.
- Households with low-voltage batteries: It’s a natural fit if you already own, or prefer, a 48V battery system.
However, if you’d rather use a high-voltage battery, consider a Solis high-voltage hybrid such as the S6-EH3P(5-10)K-H-AU.
