Own electricity for a three-phase supply
S5-GR3P20K uses module energy for normal grid-connected operation in a home, workshop or smaller business. Its 20000 W rating describes conversion power; daily kWh depend on irradiation, orientation and array size. Operation requires a PV array and connected utility grid. Local loads use generation directly at the supply point.
Two MPPTs for array design
Two independent trackers follow separate string groups. This model accepts up to 4 strings, two per MPPT. Operating current is limited to 32 A and short-circuit current to 40 A per tracker. Recommended maximum array power is 30000 Wp, start-up voltage 180 V, MPPT range 160–1000 V and maximum DC voltage 1100 V. Design compares actual module currents and open-circuit voltage at the local minimum temperature.
Output, phases and efficiency
The datasheet specifies 20000 W rated output, 22000 W maximum AC output and 22000 VA apparent power. Connection is 3/N/PE at 220/380 or 230/400 V, 50/60 Hz. Maximum efficiency is 98.7 %, European efficiency 98.1 % and THDi below 2 %. Adjustable power factor supports the actual grid requirements at the supply point.
Three-phase metering and export
The optional DTSD1352-C measures energy flow directly up to 80 A or through matching 150 A/5 A transformers. The manual also abbreviates the model to DTSD1352. A two-pin communication connector links the meter; its communication terminals are 21 A and 22 B. Export management supports grid-side or load-side metering. Select the actual meter and version as installation components.
Power control for the connection
Internal EPM configures permitted export and metering mode. Mode 01 uses average three-phase consumption; mode 02 bases limiting on the lowest-loaded phase. Configurable failsafe can report lost metering and stop generation. External EPM uses 5G-EPM or Others-EPM according to the actual device. Commissioning verifies flow direction and response.
Monitoring and generation overview
The LCD shows voltage, current, power, frequency, energy and operating state. Separate views track daily, monthly and yearly generation; diagnosis retains the latest 100 alarms and 100 warnings. An optional Wi-Fi or GPRS logger connects the system to monitoring. A 24-hour consumption overview uses a grid-side meter, enabled 24H Switch and configured Solis monitoring. Inverter addresses for shared monitoring range from 01 to 99.
Construction and operating environment
The 310 × 563 × 219 mm enclosure weighs 20.8 kg. The model uses intelligent fan cooling; typical noise is below 60 dB(A). IP66 is complemented by a −25 to +60 °C operating range, 0–100 % humidity and altitude up to 4000 m. A suitable indoor or outdoor location provides airflow and shelter from direct sun and rain.
Mounting and model-specific connections
Mount on a firm fire-resistant structure with appropriate clearance. The manual allows vertical mounting within ±5° or backward tilt up to 15°. The AC connector distinguishes L1, L2, L3, N and PE; the external earthing point uses an M6 lug and copper conductor of at least 6 mm². DC uses MC4 and 4–6 mm² conductors. Exact AC cross-section, torques and recommended breaker for this variant are listed in the technical overview.
Protection and logic control
Integrated functions cover DC polarity, short circuit, AC overcurrent, surge, grid monitoring, anti-islanding and temperature protection. The current datasheet lists AFCI 2.0 as optional. DRM uses RJ45 pins 5 and 6; when enabled, opening the contact allows output reduction to 0 W within five seconds according to the grid profile. Active power, reactive power and PF Curve settings match the actual connection.
Supplied inverter and system components
The standard package includes the inverter, backplate, two fastening screws, 4 DC connectors, one AC connector, one RJ45 connector and manual. This offer includes the DC switch. Select PV modules, meter, logger, wiring, protection and mounting accessories for the whole plant design. Any energy storage is provided by a separately designed compatible battery system with an appropriate converter.
Design around generation and consumption
Selection combines PV output, string voltage and current, available three-phase grid connection and the local consumption profile. Required energy in kWh is assessed separately from instantaneous kW. The Batterado product enquiry helps match system components. For storage the manual specifies −40 to +70 °C and 0–95 % non-condensing humidity; packaged units may be stacked up to three high.
