What is a 2.2 kW 900VDC 3-Phase/380VAC irrigation pump inverter?
The TommaTech 2.2 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.

Which projects is it suitable for?
This model is intended for small-scale gardens, greenhouses and single-well olive or citrus plots. The pump motor is in the 2.2 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
During Antalya's long, hot summer season irrigation demand peaks; since this demand coincides with the hours when the sun is strongest, the solar pump concept is a natural fit for the region. 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.
