Photovoltaic Inverter
The solar inverter is the heart of the PV System. The energy produced by solar panels will be converted into electrical energy (DC), which in turn need to be converted into acceptable form (AC) to run electrical devices.
Being a world leader in Power conversion technology, Delta offers a complete product range of solar inverters, accessories and services to our partners and installers and the best photovoltaic systems to maximize profit.
Delta’s state-of-the-art high frequency topology and MPPT equipped portfolio includes Grid-tied range of RPI series from 3KW to 125KW and DelCEN Series 1 MW to 3 MW. Our inverters are compatible for both crystalline and thin film panels. Delta’s product range aims at catering customers with home, commercial and utility scale inverter requirements.
RPI & DelCEN solar inverters are not only the heart of your system, but also the intelligent control equipment of your power generation in conjunction with the monitoring systems offered by Delta.
Delta’s solar inverters are multifaceted and can be used in every system size as well as are compatible with all commercially available solar modules and system components.
Delta solar inverters come with a standard warranty of 5 years, which can of course be extended to 10 years
Delta is a leading provider of inverter models to consumers that are customized to Indian grid conditions. In addition to their Industry’s high efficiency, our inverters are characterized by a long service life and are easy to install, maintain and monitor. With our well-established local presence and highly motivated and trained Photovoltaic solutions’ team, we will be offering Delta customers fast and reliable local service support in terms of Application Engineering and after sales service.
Wind Converters
A doubly-fed induction generator (DFIG) converter is a key component in a DFIG wind turbine, a mainstream technology for wind turbines. It features grid-friendly operation to enables optimization of the system in wind turbines. Delta converters are available for 2.0, 2.5 and 3.0 MW DFIG Wind Turbines.
The stator of the doubly-fed induction generator is connected to the gr id through the main circuit breaker while the rotor is connected through DFIG converter to the grid. When a turbine’s rotation speed varies with the wind speed, the converter changes the frequenc y of the rotor magnetizing current by controlling the excitation current frequency of the rotor, which results in the output voltage and frequency of turbines in consistent with those of the grid.
ADFIG converter r consists o f a distribution cabinet , control cabinet and power cabinet . The distribution cabinet provides the housing for the switch gears which connect the converter and the grid as well as the stator. The auxiliary power supplies and the protection switches are included to meet customers ’distribution requirements . The control cabinet provides signal conditioning, control, and communication. The power cabinet enables the interaction and the transmission between roto r slip power and the grid , and controls the rotor excitation current , thus controlling the voltage, frequency, and active and reactive status of the stator.
