Description
xSolis 80kW Three Phase Hybrid Solar Inverter High Voltage S6-EH3P80K10-NV-YD-H
The Solis S6-EH3P80K10-NV-YD-H is an 80kW three phase high voltage hybrid inverter for commercial solar PV and battery storage. It brings a large solar array, a high voltage lithium battery bank, the grid and a generator together in one unit, so a site can use its own solar during the day, store the surplus and keep essential loads running through a power cut.
It is the entry model of the Solis Solarator 80 to 125K series and suits farms, workshops, schools, cold stores and small industrial units with a three phase supply. Ten MPPT trackers, twin battery ports and fast on-grid to off-grid switching make it easy to design around, on a new build or as a retrofit to existing PV.
High Solar Input for Large Arrays
The 80kW model supports a recommended PV array of up to 160kW, twice its rated output, with a maximum input voltage of 1000V, a rated voltage of 600V and a wide MPPT range from 150V to 950V. Ten independent MPPT trackers take 20 strings in total, and each input handles up to 42A (21A per string), so it works with high power PV modules.
Two Ports for High Voltage Batteries
The inverter works with high voltage lithium batteries from 300V to 950V. Two independent battery ports, each with its own BMS connection, charge and discharge at up to 100A each, giving up to 200A of combined charge current for fast charging. Solis rates the range for battery modules from 100Ah to 314Ah, and the twin ports make it straightforward to split storage or add capacity later. Battery communication is via CAN.
Backup Power, Generator and Weak Grid Support
On-grid to off-grid switching takes less than 10ms for a single inverter, so critical loads carry on through a grid failure. In backup mode the 80kW model delivers 160% of rated power for 10 seconds and 200% for 200 milliseconds, which helps start motors, compressors and pumps. Battery reserve management and intelligent load prioritisation stretch the supply time for the loads that matter most.
A dedicated generator input rated at 80kW, flexible control for weak grid and genset hybrid systems, and a utility bypass that feeds backup loads directly from the grid all help keep a site running when the supply is unreliable.
Commercial Energy Management
Solar and storage work together for demand management and anti reverse flow (export limiting), and dynamic reactive power compensation helps improve the site power factor and reduce reactive power charges. AI integration and virtual power plant (VPP) readiness support dynamic tariff optimisation. Both DC and AC coupling are supported, and a three in one interface connects on-grid PV, wind power and diesel generators.
Parallel Operation up to 1.25MW
Multiple units can run in parallel for systems up to 1.25MW, with a Solis STS cabinet recommended above 6 inverters. In a parallel system of up to 6 inverters the switchover time is below 20ms. Each phase carries up to 33% of rated power, so plan for a balanced three phase load.
Monitoring and Communication
A 7 inch LCD display, Bluetooth and the Solis app handle local setup and commissioning. Wi-Fi, LAN and Bluetooth are standard and 4G is optional. The unit also provides two CAN-BMS ports, two CAN parallel ports, RS485 for the meter, RS485, DRM, five digital inputs and four digital outputs. This version is supplied with a CT or meter in the box.
Built for Demanding Sites
An IP66 enclosure, intelligent redundant fan cooling and Solis patented cooling design keep the inverter working from -25°C to +60°C, in 0 to 100% relative humidity and at altitudes up to 3000m.
Applications
- Commercial and industrial solar PV with battery storage
- Farms, cold stores and agricultural buildings
- Factories, warehouses and workshops
- Peak demand reduction and export limiting
- Backup power for critical loads
- Sites with a weak grid or a standby generator
Installation Notes
The S6-EH3P80K10-NV-YD-H is a high voltage battery inverter. It must only be used with compatible high voltage lithium battery systems in the 300V to 950V range and is not suitable for 48V battery banks. Solis lists G99 among the planned grid connection standards for this range, so please confirm certification status with us before specifying it for a UK grid connection. Installation, commissioning and grid connection must be completed by a qualified installer, with correct DC fusing, AC protection, surge protection and earthing. The unit weighs 170kg and measures 1174 x 814 x 400mm, so plan handling and mounting accordingly.
