## Commercial module generation

S6-GC3P25K03-NV-ND uses a PV array for the three-phase supply of a business, workshop or larger building. Its 25 kW rating describes instantaneous conversion power; kWh energy depends on sun, orientation and array size. The inverter operates with connected modules and utility grid. Generation serves local consumption and export can be managed for the connection conditions.

## Three MPPTs and high-current modules

Three independent trackers each serve two strings, six overall. Each MPPT supports 42 A input and 52.5 A short-circuit current with 25000 W maximum input power. Recommended maximum total array power is 37500 Wp. Start-up begins at 180 V, MPPT spans 180–1000 V and maximum voltage is 1100 V. Design compares actual module currents and string voltage at the local minimum temperature; separate trackers provide clear grouping of modules.

## Exact output and efficiency

Rated and maximum AC output are 25000 W, with 25000 VA maximum apparent power. Rated and maximum current are 38.0 / 36.1 A at 380/400 V. Connection 3/N/PE uses 220/380 or 230/400 V at 50/60 Hz. Maximum efficiency 98.5% is complemented by 98% European efficiency and THDi below 3%. Adjustable power factor supports grid requirements. Transformerless construction has night consumption below 1 W.

## Bluetooth and SolisCloud in use

Local setup uses Bluetooth in the SolisCloud app for Android or iOS. Installer and Owner roles provide corresponding controls. Home shows PV/AC data and daily, monthly, yearly and total generation. Information includes model, serial number, output, DSP/HMI firmware and grid code. Diagnosis displays the alarm, its code, grade and relevant guidance. Status LEDs provide a quick check of power, operation, alarm and Bluetooth.

## Two independent RS485 interfaces

The 16-pin COM provides two independent interfaces. RS485-1 uses input 5 A/6 B and output 7 A/8 B for daisy chaining and EPM control. RS485-2 on pins 1 A/2 B serves the meter or, according to configuration, a third-party controller and monitoring platform. A separate USB COM serves an optional logger. For remote monitoring the manual lists Wi-Fi/GPRS/LAN sticks and multi-device boxes. Pinout, cable sizes and connector torques appear in the technical overview.

## Metering and export control

A compatible three-phase CT meter or suitable smart sensor provides export-control data. The app selects the actual meter, CT ratio/direction and permitted export. Built-in EPM serves one inverter; external EPM serves multiple devices. Modes include CT Sensor, Meter in Grid, Meter in Load and dedicated 24-hour monitoring modes. A full-day overview uses grid-side metering and enabled 24-Hour Load Monitoring with Solis monitoring.

## Adapting to the grid connection

Active output, PF Curve and power-change gradients help match generation to the connection. Grid modes include Volt-watt, Volt-var, fixed power factor, fixed reactive power and Power-PF. Grid protection parameters follow the approved connection. Metering failsafe and any G100V2 settings match the actual regulation scheme. The app also provides time, device addressing, generation calibration and multi-peak MPPT scan interval settings.

## Construction and environment

The 355 × 625 × 250 mm enclosure weighs 25.3 kg and offers IP66 with C5 corrosion resistance. Dust-tight protection against powerful water jets supports suitable indoor or outdoor locations. Intelligent fan cooling includes Silent, Normal and Performance modes. The current datasheet specifies typical noise at most 55 dB(A). Operating conditions are −25 to +60°C,0–100% humidity and altitude up to 4000 m. The site provides airflow and shelter from direct sun and rain.

## Mounting and electrical connections

A firm fire-resistant structure supports vertical mounting or backward tilt up to 15°. The manual shows 500 mm clearance above, at the sides and above floor. Two people or suitable lifting equipment use the upper handling points. External earthing uses at least 16 mm² copper and an M6 lug. DC conductors are 4–6 mm², AC 6–25 mm² with 25 mm² recommended; actual routing and design determine the size. AC terminal torque is 3–4 Nm and recommended protection 63 A. Exact bracket dimensions, cable details and diagrams appear in the overview and gallery.

## Protection and selected equipment

This offer includes AFCI 2.0 arc protection together with the DC switch and C5. Integrated functions cover DC polarity, short circuit, AC overcurrent, surge, grid monitoring, anti-islanding and temperature. The European logic interface uses pins 13 RefGen and 14 GND; when enabled, opening the contact limits output to 0 W within 5 s. Exact settings match the grid profile and control design.

## Equipment and complete system design

The package includes inverter, bracket, two screws, six DC connectors, five OT lugs, AC cover and quick installation guide. The 16-pin COM connector is a connection component according to the manual. Optional logger, meter or sensor, external EPM, modules and mounting components are selected for the plant. kW output is assessed separately from kWh energy; any storage uses a separately designed compatible battery system with an appropriate converter. Batterado helps match suitable components. Storage conditions are −40 to +70°C,0–95% non-condensing humidity and up to three packaged units high.
