What is a 250 kW 900VDC 3-Phase/380VAC irrigation pump inverter?
The TommaTech 250 kW 900VDC 3-Phase/380VAC Irrigation Pump Inverter is an irrigation pump inverter that converts the direct current from the PV array so that it can drive the pump motor. Thanks to its wide MPPT operating voltage range, it aims to draw output from the panels even though irradiance changes during the day. Settings are made on the device itself using the multifunction keypad.
Key technical specifications
The technical specifications are summarized below according to the information in the product name. The device comes in a metal enclosure. According to the supplier, the total warranty is 7 years: 2-year product warranty and 5-year parts warranty.

|---|---|
| Rated power | 250 kW |
| Maximum DC input | 900 V |
| AC / phase | 3 phase / 380 VAC |
| Enclosure | Metal enclosure |
Which projects is it suitable for?
This model is intended for irrigation associations, cooperatives and large pump stations that feed a very large area from a single center. The pump motor is in the 250 kW class; the number of panels and the string voltage must be designed so that the 900 VDC upper limit is not exceeded, also taking cold-morning conditions into account. Because exceeding the voltage limit can damage the device, the string calculation is always done before installation.
Use in Antalya and Solar Nexo support
In Antalya, irrigation demand and solar irradiance coincide in the summer months; because the pump runs on the panels' output in the middle of the day, no additional grid energy is needed. Solar Nexo reviews the well and pump information, designs the PV array, cabling and protections, and installs and commissions the system. The datasheet, certificates and user manual can be downloaded from the product page; you can contact our team for technical support after installation.
