Power for utility PV plants
Solis S6-GU3P350K06-EV-ND delivers 350 kW of PV power to a three-phase 800 V IT system in a utility plant. Six MPPTs serve thirty strings at up to 1500 V DC. This configuration includes PLC communication, PID functions, DC switches and Type II surge protection on both AC and DC sides. The solution is engineered together with a matching transformer, protection and plant control.
Six trackers and thirty strings
Each MPPT connects five strings with an 80 A maximum operating input and 125 A short-circuit limit. MPPT operating range is 480–1500 V, rated DC voltage 1080 V and start-up voltage 500 V. Strings are designed for cold open-circuit voltage, module current and series module count. Panel type, orientation, tilt and series counts are matched within each tracker for a shared operating point.
800 V connection and efficiency
The AC side uses L1, L2, L3 and PE at 800 V nominal. Operating voltage is 640–920 V with 252.6 A maximum output current. Rated active and maximum apparent output are 350 kW /350 kVA. Maximum efficiency reaches 99.0% and European efficiency 98.7%. Grid code, protection and transformer interface follow the plant’s specific connection; energy production in kWh follows array output and irradiation over time.
Protection and PV-array diagnostics
Integrated functions cover grid monitoring, anti-islanding, DC polarity, short-circuit, overcurrent and temperature protection. AC/DC Type II SPD is complemented by terminal temperature sensing. The manufacturer specifies intelligent string interruption, remote DC-switch release and MPPT-level insulation diagnostics. Individual-string monitoring and I/V-curve scanning support assessment of the PV array by the service team.
PID in a correctly designed system
Daytime Anti-PID and nighttime PID recovery support suitable PV modules. The manual requires an IT transformer and 1.8/3 kV-rated AC cable for this function; daytime operation uses a Solis S3-logger. These components and settings are included in the installation design. The quoted PID functions belong to PV generation and plant operation.
Reactive power and Night SVG
The inverter supports power-factor and reactive-power control according to grid requirements. Once enabled, Night SVG allows reactive-power settings from −60% to +60% of rated power. The manufacturer’s 20 ms response figure describes reactive-power control. Parameters are configured for the specific grid code and higher-level plant controller.
PLC and daisy-chain RS485
This offer includes PLC. The design selects PLC or RS485 as the communication path; the manual allows up to 1000 m over overhead AC lines and 500 m over buried lines for PLC. RS485 serves a chain of up to 15 inverters over 1000 m. The eight-pin COM connector provides separate input/output pairs and shield connections. Matching logger, PLC CCO and any PPC/SCADA are selected for the entire plant.
Local Bluetooth operation
LED indicators show local status and SolisCloud connects over Bluetooth. The installer role performs initial configuration, with owner access supporting ongoing visibility. Home, Info, Alarm and Settings display power/energy, PV/AC data, firmware, grid code and diagnostics. Output, power factor, EPM and grid protection are configured within the approved connection design.
Construction and operating environment
The 1098 ×813 ×378.5 mm enclosure has a 119 kg reference weight in the current manual. IP66 is complemented by C5-M corrosion protection. The −30 to +60°C operating range and intelligent redundant fan cooling support operation at an engineered outdoor site. Mounting provides required clearances, airflow and service access; typical noise in the manual is at most 80 dB(A).
Power conductors and earthing
According to the manual, M12 AC terminals use 95–400 mm² conductors and 20–30 Nm torque. Aluminium conductors use suitable bimetallic transition lugs. The protective conductor is sized to at least half the phase-conductor section; PE and external earthing have separate connection points and torque values. Reference 350/400 A AC protection is selected for the specific 800 V IT design. DC connectors and cables are prepared for the actual array according to the manual.
Delivery and overall design
The package includes inverter, mounting bracket, fasteners,30 DC connectors, eight-pin COM connector, four handles, sealing gland and manual. Modules, transformer, switchgear, metering, control and cable routes are designed as a connected whole. Any storage uses a separately engineered battery system. Selection first establishes plant output,800 V architecture, string parameters and control requirements, then assigns the specific components.
