80-125kW | Three-phase High Voltage Commercial Hybrid Inverter
The Solis S6-EH3P(80-125)K10-NV-YD-H-AU is the largest model in Solis’s Solarator Series of three-phase hybrid inverters built for high-voltage batteries. It comes in three ratings, 80kW, 100kW and 125kW, and is designed for commercial and industrial energy storage. With 10 MPPTs, two independent battery ports and parallel operation of up to 1.25MW, it’s built for large sites that need serious solar and storage capacity. But how does it perform where it matters?
Key features of the Solis S6-EH3P(80-125)K10-NV-YD-H-AU Hybrid Inverter
- 10 MPPTs with high-current inputs: Ten independent MPPTs, with up to 21A per string, suit large rooftops with multiple orientations and the latest high-power solar panels.
- 200% PV input capacity: You can connect up to twice the inverter’s rated power in solar panels, maximising solar generation.
- Dual independent battery ports: Two battery inputs, each controlled separately, allow flexible configurations and fast charging at up to 200A combined.
- Overload capacity: The backup port can handle short power surges when heavy equipment starts.
- Seamless backup switching: It switches from grid to backup power in under 10ms, keeping operations running during outages.
- Weak grid and generator hybrid control: Flexible control modes suit sites with unstable grid supply or that run generators alongside solar.
- Demand management and anti-reverse flow: Solar and battery work together to limit peak grid demand and prevent unwanted export.
- Dynamic reactive power compensation: It improves the site’s power factor, helping reduce reactive power charges.
- Utility bypass: The grid can supply backup loads directly when needed.
- DC and AC coupling: It can connect to solar panels directly or to existing grid-tied solar, making retrofits and expansions easy.
- Battery reserve management: Set how much battery charge is held back for outages across different scenarios.
- Three-in-one interface: A single port integrates grid-tied solar, wind turbines and diesel generators.
- AI-powered and VPP-ready: Dynamic tariff optimisation and virtual power plant participation help reduce energy costs and create extra revenue.
- Parallel operation up to 1.25MW: Multiple units can run in parallel to scale system capacity.
- 7-inch LCD screen and Bluetooth app: A large display and app-based setup make commissioning and local monitoring simple.
- IP66 rated: Built for outdoor installation in harsh Australian conditions.

Applications for the Solis S6-EH3P(80-125)K10-NV-YD-H-AU Hybrid Inverter
The Solis S6-EH3P(80-125)K10-NV-YD-H-AU is well-suited for:
- Industrial facilities: Ideal for factories, manufacturing plants and cold storage facilities with large, continuous energy loads.
- Large commercial buildings: Suits shopping centres, office buildings, hotels and warehouses with big rooftops and high daytime energy use.
- Agriculture: A strong fit for large farms, irrigation systems and processing facilities.
- Remote sites and microgrids: Suits mines, remote communities and other off-grid or fringe-of-grid locations.
Pros of the Solis S6-EH3P(80-125)K10-NV-YD-H-AU Hybrid Inverter
- Highly efficient battery storage: 98.2% PV-to-battery charging and 97.0% discharge efficiency keep energy losses low.
- Broad battery compatibility: A wide 300–950V battery range works with 100–314Ah battery modules, giving more choice and helping reduce overall system costs.
- Critical load prioritisation: Intelligent load management extends how long essential equipment can keep running during outages.
- Built for high temperatures: Patented cooling technology keeps the inverter running reliably in hot conditions.
- Advanced safety monitoring: Insulation resistance monitoring, residual current detection, Type II surge protection on both the DC and AC sides, and an integrated PV switch protect the system and site.
- Extensive site integration: Wi-Fi, LAN and Bluetooth come standard, with multiple digital inputs and outputs for connecting site controls and equipment.
Cons of the Solis S6-EH3P(80-125)K10-NV-YD-H-AU Hybrid Inverter
- Extremely heavy: At 170 kg and over 1.1 metres wide, it needs mechanical lifting equipment and a suitable installation area.
- Limited per-phase output: Each phase can supply only up to 33% of rated power, which may limit sites with heavily unbalanced loads.
- Short overload on larger models: The 100K and 125K models handle only 140% overload for 10 seconds, which may not suit equipment with heavy start-up surges.
- High standby consumption: It draws up to 45W while idle.
- High-voltage lithium batteries only: It doesn’t support low-voltage or lead-acid batteries.
- Extra equipment for large systems: Parallel systems of more than six units need a Solis STS cabinet, adding to project costs.
- AFCI is optional: Arc-fault protection isn’t standard on every unit, so check with your installer.
Is the Solis S6-EH3P(80-125)K10-NV-YD-H-AU Hybrid Inverter right for you?
The Solis S6-EH3P(80-125)K10-NV-YD-H-AU is an excellent choice for:
- Businesses with large energy bills: If your site uses a lot of power, this system can significantly cut your electricity costs.
- Operations that rely on continuous power: It suits sites where outages mean lost production, spoiled stock or safety risks.
- Large-scale and multi-stage projects: If you’re planning a big solar and storage project or expanding in stages, this range can scale to meet your needs.
However, if your site’s energy needs are more modest, the smaller Solis S6-EH3P(29.9-50)K-H-AU may be more cost-effective.
