Grid Tie Inverters

Unidrive SPV Photovoltaic Grid Tie Inverter* Solutions

Over 12 MW per day, every day

SPV ModulesFor 35 years Control Techniques has specialized in power control and conversion. We currently manufacture more than 12MW of inverters per day worldwide. Our intelligent scaleable technology ensures optimum efficiency across varying radiation intensities, typically achieving 97% to 98%. This is achieved using the following key methods:

Inverter teaming operation

To enhance system efficiency over a wide radiation range, a separate smaller inverter is used during low light conditions and a larger inverter automatically switches in above a defined threshold. The small inverter is typically rated at 20% of array peak power, and the larger inverter at 100%+.

The picture below shows a complete solution for a 1.6MW array together with a 350kW teaming inverter for low light conditions. The complete system dimensions including the control section are 6000 wide x 2100* high x 800 deep (mm) (*including a 100mm plinth).

  • Assured performance

  • Proven reliability

  • Built-in redundancy

*A grid-tie inverter, or a (GTI) is a special type of electrical inverter that is used in a renewable energy power system to convert direct current (DC) into alternating current (AC) and feed it into the utility grid. An inverter is an electrical device that converts direct current to alternating current. Inverters are also referred to as AC Inverters, Power Inverters and AC Power Inverters.
