SPI Series 160-250 kW Cabinet-Type Irrigation Inverters

TommaTech SPI Series Cabinet-Type irrigation inverters serve the highest power range displayed in the official CW Enerji category. Three exact models provide inverter ratings of 160 kW, 185 kW and 250 kW, with officially listed compatible motor powers of 132 kW, 160 kW and 220 kW.

The family uses the same 300-750 VDC recommended operating range and 900 VDC maximum input as the standard three-phase SPI platform. High current capability and vertical-base cabinet construction make these models suitable for large agricultural pumping stations, high-volume water transfer and major irrigation infrastructure.

Final engineering should include hydraulic load analysis, motor-start and current verification, PV array design, protective devices, harmonic and cable assessment, ventilation, enclosure protection and local electrical compliance. These models should be treated as engineered project equipment rather than stand-alone catalogue items.

Recommended Applications

• Large-scale agricultural irrigation
• High-capacity deep-well pumping
• Irrigation cooperatives and shared water systems
• Large reservoir-filling and water-transfer projects
• Main-pump stations serving extensive drip or sprinkler networks
• Agricultural infrastructure using 132-220 kW pump motors

Model Selection Guidance

Use SPI-TT-160.0-TF for motors up to the officially listed 132 kW class, SPI-TT-185.0-TF for the 160 kW motor class and SPI-TT-250.0-TF for the 220 kW motor class, subject to nameplate current and project engineering. The category does not list the 200 kW or 220 kW inverter models shown in the broader technical sheet; they are therefore excluded from this CMS range.

Essential Shared Specifications

• AC input range: 380 V (-15%) to 440 V (+10%), three phase.
• Standard product protection level is stated as IP20; the complete installation must provide suitable environmental protection and cooling.
• Manual operating conditions: -10°C to +50°C with derating above 40°C; RH up to 90% without condensation.
• Altitude above 1,000 m requires 1% derating for every additional 100 m according to the official manual.
• The manual requires a DC input breaker; Type II DC surge protection is specified where the PV cable run exceeds 10 m.
• An output reactor is recommended when the motor cable exceeds 50 m.
• MPPT, water-level control, weak-light sleep/wake, PV/mains selection and fault diagnostics are configurable through the common SPI control platform.
